IV. I. Honey bee Resources: Biology and Management
IV. i . l . Diversity, comb architecture and host specificity of honeybees
More than three fourth of the known animals are insects. They are the
most successful creatures among all the life forms on earth. Out of the 10
lakh insects in the whole world, about 20,000 of them are bees, of which a
few are honey producing bees belonging to the genus Apis, Trigona,
Melipona and Bombus. A majority of the honey production is mediated by
the genera, Apis and Trigona.
Asia has three native tropical species of Apis, the hive bee A. cerana
and the wild bees A. dorsata and A. florea. A. mellifera usually thrives in
temperate and sub-tropical climates and in some tropical regions where
there are no native honeybees.
In India, the genus Apis is represented by three different species,
A. dorsata, A. cerana, and A. f/orea. Apis cerana is found in two varietal
forms, A. cerana var. cerana and A. cerana var. indica. Even though, the
genera Trigona and Melipona are less productive, they are also utilized in
honey production.
The species of Apis are the common honeybees and are readily
distinguished by their size. A. dorsata Fabr, being the largest, A. c. indica
Fabr., the medium-sized and A. florea Fabr., the smallest. While all three
are common in India, they do not all appear to occur together.
Observations on dwelling places for individual honeybee species
presented strict preferences for host trees. The host preference varied
between different bee species. This host specificity was determined by the
behaviour of honeybee species, branching pattern, flowering phenology of
preferred species and tendency of tree species to form crevices in tree
trunks. Table 2 sumn~arizes the host preferences shown by different
honeybee species in the area under investigation.
Except in modern movable-comb hive, bees construct their nest by
building a group of parallel combs vertically downwards from the roof of the
hive or nest cavity. The distance they leave between the combs is an in built
character of the bee species and varies slightly for different species or sub-
species according to their body size. The bees observe this spacing very
precisely with regard to the combs in which brood is reared; these are
normally the central ones, where the temperature can most easily be
controlled. There is a greater tolerance to the spacing between the honey
storage combs above and around the brood nest.
Different honeybee species make their hives in different patterns and
this correspond to the behaviour of honeybees. The structural differences in
combs reflect even in the nature of honey. Hive architecture play a
significant role in the purity of squeezed honey and pollen concentration in
honey. The host specificity and the structural differences in hive make up of
different species are summarized below.

IV. 1. 1. 1. Apis dorsata
These are comrnonly known as Rock bees and are the big bees that
build large nests in the forest and away from cultivation. These are photo
tactic bees and make their dwellings on parallel branches of huge trees. The
hives appear as semi-.lunar structures and occur widely in natural forests.
The comb cells near to the branch are found filled with pollen loads, below
which the cells have larvae and the lower most part of the hive is filled with
honey. The presence of larval zone in between the pollen and honey zone is
a distinguishable feature of these combs. This brings ease for larval feeding
by pollen as well as honey. Majority of the honey produced in natural
forests is contributed by this species and is not yet proved to be tamable for
honey industry.
These bees generally preferred the parallel branches of huge trees
like Bombax ceiba L., Artocarpus hirsutus and Knema attenuata. A strict
specificity of A. dorsata to Bombax trees was a significant observation in the
natural forest ecosystern. Bombax ceiba L., a member of Bombacaceae, is
a prickly tree ranging from a height of about 6m to 60m. The flowering period
coincides with the swarming of A. dorsata. The coincidence of colony
multiplication, swarming and search for new nesting place with the well built
tree architecture with loosely held parallel branches allowing sufficient
sunlight between, efficient floral display and abundant rewards of pollen and
nectar might have contributed for this specificity. The tree put forth many
horizontal branches and flowering extends from October to February. During
this season, the trees are completely defoliated and the bright red flowers
with efficient floral display fill the whole canopy. The flowers are auxiliary,
solitary or 1-3 together. In most of the seasons, one and the same tree was
found to have many hives and the number varied between 6 to even 48.
Similarly. Artocerpus hirsutus and Knema attenuata also presents a
well-built system of tree architecture offering sufficient nesting places for
A. dorsata bees. These are frequent in evergreen and semi evergreen
forests at lower elevations adjacent to streams or rivers in Kallar and
Bonnoccord.
IV. 1.1.2. Apis cerana indica F .
These are photophobic bees and make their dwellings in crevices of
tree trunks. These are commonly known as Indian bees and are the
commercially exploited bees in beekeeping. They are smaller than the rock
bees and are less aggressive than the former. In artificial hives, they store
honey in upper hive cells, pollen in lower cells and the larva in between. In
natural forest hives also they follow the same pattern but without a distinct
demarcation between the zones but rather with a transition from one to
other.
IV. 1.1.3. Apisflorea F.
These are the smallest honeybees and known as little bees. They
make their dwelling on small branches of bush-like plants and are photo
tactic. They store honey in those cells near to the branch where the
attachment of the hive occurs, larva below this zone and pollen in lower most
cells.
IV. 1 . 1 . 4 . Trigona irridipennis
These are sting less bees, which store nectar and pollen in globular
cells. With reference to the pattern of storage of pollen and honey, two
different forms ex~st (Plate 1 ).
'Cherutheneecha': This is one form of T. irridipennis. In this the pollen and
honey are stored in separate region. In the hive, the globular cells containing
larvae are seen in between the honey and pollen zone (Plate 1- Fig. a -c).
'Arakki': This seems to be a variant of the above one and here a beak like
projection of bees wax guards the entrances of the hives. In these hives,
there is no distinction between the honey zone and the pollen zone. Here
pollen and honey are stored in intermittent cells and the larval cells are near
to this zone. The honey obtained from these hives contains more
concentration of pollen grains and the occurrence of honey and pollen in
intermittent cells may be the reason for this (Plate 1- Fig. d - h).
IV.1.2. Annual bee management and commercial honey production
Bee keeping as an industry is not getting much attention here in
Kerala even though 'the climatic and vegetation elements are supportive.
However, the farmers who earn their living through this are actively engaged
in this profession. Topography and vegetation constituents of this district are
positive elements in honeybee management. Mountainous and midland
zones are the potential sites of honey production. Hilly areas with flourishing
vegetation constitute floral elements, which can contribute critical resources
for honeybees throughout the year except during rainy season. But these
areas are not getting exploited in this respect. Lack of scientific knowledge
62
b of 'Cherutheneecha' ; b. Pollen and larval zone of 'Cherutheneecha , d. Bees wax guardlng the entrance of 'Arakkl' (Slde view) ;
on seasonal flowering and potentiality of critical resources these plants can
offer are the two major factors for non- exploitation. Inaccessibility to some
areas also creates hindrances to this. But the accessible available resources
are in no way utilized by the commercial beekeepers.
The maximum utilization of floral elements for honey industry has
been concentrated on midland zone, where most of the areas are under
cultivation. Hevea brasiliensis, one of the major plantation components in
this area is utilized by beekeepers in honey production. Extra floral nectaries
at the base of the compound leaves secrete nectariferous liquid during
flushing of trees. This period, Jan-May is the honey flow season in this
region. While mountainous and midland zones are potential areas of honey
production, the coastal zone having coconut cultivation serves winter
management areas for honeybees. Another interesting factor in this respect
is that most of the beekeepers of the district belong to the coastal zone and
only a few belong to m~dland areas.
The professional beekeepers of the coastal zone practice migration of
their hives to midland and a part of hilly tracks, before honey season. By the
month of October, the beekeepers transfer their hives to Rubber plantations
and the areas in between Rubber plantation and forest outskirts. This
transfer is done on anticipation of the flushing of Hevea trees by the end of
December and the beginning of January. During this period, they utilize the
flowering of small herbaceous plants and weeds near hive areas. These
include Antigonon, Manihot sp., Mimosa pudica, Peuraria sp., etc. Lack of
flowering plants necessitates the feeding of bees by sugar solutions. During
this period, bees actively engage in pollen collection and storage. By the
middle of January, the honey flow begins. They actively engage in nectar
collection and the beekeepers extract the honey stored in comb cells with an
interval of 8 days.
By the onset of honey flow season, the bee colonies become
populous and may undergo swarming. But the beekeepers divide the
colonies, according to the needs of individual colonies, thus adding up to the
total strength of the colonies. Then by the end of May, "honey spring" comes
to an end with the onset of monsoon. By keeping necessary amount of
honey in the combs, they' migrates their hives into the coconut laden central
zones, for monsoon management. Coconut provides the pollen necessary
for brood rearing. The monsoon with heavy rainfall is the most adverse
period for the beekeeping industry here. During this time, the bees may
easily get affected by pests and mites leading to the destruction of the hive.
So the beekeepers pay more attention to their hives by periodical
observations. At this time feeding of the hives with sugar syrup is a
necessity.
By the beginning of August, the strength of rain decreases with
intervening sunny days. Then the bees start coming out of the hive in search
of food. Cocos nucifera is the most important plant giving its pollen to the
pollinator visitor. With the storage of enough of pollen load, brood rearing
takes place. With the newly emerged little bees, the population of the
individual colonies increases and beekeepers divide the colonies. By
October the hives are ready to migrate to different parts of the district.
The winter season from October to December marks the critical brood
rearing season. During this period the pollen resources available to the
younger generation forms the limiting factor for the preparation of the bee
colony. High lands of the district with diverse flora are not utilized for the
present time for bee keeping. The study has also been focused on the
utilization of floral resources in the critical brood rearing season in the
transition zones of high land and midland. From this it is clear that the
highlands and nearby areas can hold the bee colony during the winter. The
presence of honey stores in these hives in a small quantity also suggests
that some plants can offer nectar resources too during this period. This can
reduce the artificial feeding rates of the colony in these periods, which is a
major problem now the bee keepers are facing.
IV.1.3. Beekeeping in Rubber plantations
The beekeepers of the state in general and the district in particular
depend on monocultures of Hevea braziliensis for commercial honey
production. Flowers are either male or female and self-pollination within an
inflorescence is roughly 10 - 20% productive as cross-pollination. Some sting
less bees of the genus 'Trigona collect pollen both in the new world and the
old, but provide minimal pollination and Apis often do not collect the pollen at
all, or only visit the extra floral nectaries and very seldom visit the female
flowers.
Beekeepers practice migratory beekeeping to these plantations at the
midland zone after the monsoon management at the coconut laden coastal
zone. They m~grate their bee colonies by the month of October, anticipating
the flushing of Hevea trees by December. The bees forage on the extra floral
nectaries of these trees and make honey from this nectar. The dependence
of beekeepers on monoculture plantations like Rubber, even though gives
sufficient quantity, the necessary quality for export is not reached and this is
a major problem for honey exporters in Kerala. The exploitation of natural
forest resources of southern Western Ghats may solve the problem. For this,
forest management policies must have a flexibility to accommodate the
requirements of the beekeepers.
IV.1.4. Impact of Thai sac brood Disease
The period between 1990 -1994 created severe damage to the
A. cerana indica colonies of many beekeepers. Many people gave up this
business and turned to other activities. But those colonies which overcome
this menace, started establishment during 1995 and at present many people
have better colonies and had a better income during the last few honey flow
seasons. The viral disease that affected the apiary bees has an impact on
the natural forest A. cerana colonies also. The frequency of occurrence of
colonies also diminished during the peak period of the disease. A gap then
generated for nectar and pollen sources in natural habitat. This might have
created an emergence of Trigona colonies in the forests.
IV.1.5. Introduction of Apis rnellifera
The beekeepers of the district made an attempt to domesticate the
introduced Itallan bee, the Apis mellifera through Khadi and Village
Industries Commission. The attempt ended in utter failure. The probable
reasons are,
1. Large size of the bees results in slow speed in foraging and hence, bee-
eaters especially Drongo catch these bees with more ease than A. c. indica
bees. Hence, few bees return the hive after each foraging mission. This
reduces the colony strength resulting in loss of the colony.
2. Inadequacy of large foraging field blossoms like mustard in northern
states.
3.Different specles of honeybees have evolved through the ages under
particular environmental and climatic conditions to suit the local
requirements and this natural phenomenon can be the reason for the failure
of acclimatization of A. mellifera here. This confirms that the introduction of
an exotic species that has proved superior in an area may not necessarily be
superior in a different geographical region (Kshirsagar, K.K, 1968).
IV.2. Honey Plant Resources: Biology and Management
IV.2.1. FORAGING
The species vary considerably in aggression and in mode and degree
of communication between foraging workers and these differences have
profound effects on the manner in which a colony finds and harvests
resources. Some species can recruit quickly to large numbers; others do not
recruit at all. Some species consistently forage in groups, but others forage
as solitary workers. Some species employ aggression as a competitive
technique to sequester resources from rival bees and other species are
rarely seen in agonistic encounters.
Group foraging behaviour is well suited for rapid, efficient and
monopolistic exploitation of localized, high reward resources, whereas
solitary foraging in social bees is better suited for exploiting low density, low-
reward resources. As far as A. c. indica bees are concerned, they can recruit
quickly large numbers of workers and they consistently forage in groups.
IV.2.1.1. Nectar foraging and honey production
Honey is made by bees, and their raw material for nearly all the
world's supply of honey is nectar produced in the nectaries of flowers, and a
much smaller amount comes from the plants having extra floral nectaries.
Most of the variations between honeys originate in differences between the
nectars from which the honeys are derived.
The amount of honey that can be produced from the nectar of a single
flower depends on the total amount of nectar secreted and on the sugar
concentration of the nectar. In most flowers, only a minute amount of nectar
is available at any orle time. Honey can only be made by bees after raw
materials have been collected from plants. If the nectar is inaccessible to
bees, or not sweet enough to attract them, or if the bees find a flower
tiresome to collect from because of floral structure and behaviour, then it is
unlikely that the nectar will be used for honey. So, higher nectar productivity
of a particular species does not imply that it is a good source of honey
production. Here floral structure, floral display and the bee behaviour on
individual species act together so as to offer the sweet for the bee visitor.
Neither the plants honey potential nor can the bees' foraging potential
be realized in poor weather. Bees do not fly to collect nectar if the
temperature is less than I;!" C and the plants cannot yield nectar unless the
temperature is high enough.
Rain or high humidity can make nectar more dilute and give the bees
much extra work, both in carrying nectar home and in evaporating-off the
excess water. Climatic variation is the major factor underlying year-to-year
variations in nectar flows from the same plant species apart from the
damages by diseases and pests and catastrophes such as fire.
IV.2.1.2 Nectar foraging on Bombax ceiba L.
Bombax ceiba (Semal) belonging to Bombacaceae is one of the
major elements of deciduous forest. The trees of this species emerge above
the canopy line of the forest occupying the gaps. These trees are leafless
during the blooming periods and their large sized flowers accumulate good
stores of nectar. This species is typically an ornithophilous one, offering
abundant stores of nectar for the bird visitors.
But the analysis of honey and pollen loads collected by the native
honeybee colonies showed the abundance of pollen grains of this species in
honey as well as in pollen stores of the comb cells. This implies the species
as a better resource of nectar and pollen for the honeybees. Based on this
observation, foraging of Apis cerana indica bees on this species was
analyzed.
IV.2.1.2.1. Phenology
The huge trees of this species shed the leaves during the month of
December with the onset of winter. Flowering season extends from January
to February and the flushing of leaves begins by March. The flowers are
large, showy, fleshy and red in colour. They are hermaphrodite, protandrous,
actinornorphic and pentamerous. It consists of numerous stamens arranged
in bundles. The anthers host numerous large plano-convex pollen grains.
The nectaries situated at the base of the petals secrete abundant nectar of
about 3.25-mll flower, which form the resource for visiting bees and birds.
IV.2.1.2.2. Nectar quantification
On the previous day of quantification, 4 different mature unopened
flower buds were bagged in order to avoid nectar robbing. The flowers were
marked as FI, F2, F3 and F4. The flowers FI and F2 were continuously
bagged while F3 and F4 were kept open after the first quantification of nectar
at 6.30AM. The quantification was done using micropipette with duration of
one hour. The colour of the nectar was light blue and was less dense.
The kept opened flowers were visited by Apis cerana indica foragers
for pollen collection. 'These bees collected only pollen even though flowers
contained abundant nectar. This indicated that the pollen foragers and
nectar foragers are different in Apis cerana indica bees. The details of
nectar quantification are summarized in table 3. The total amount of nectar
produced by a single flower during single day ranged from 2309 to 3696 pl.
Table 3. Nectar quantification in Bombax ceiba
IV.2.1.2.3 Quantification of flower productivity
Total nectar production of a single Bombax tree:
No. of large branches = 25
NO. of small branches in a large branch = 10
No. of branches in a tree = 25 X l o = 250
No. of branch lets in a small branch = 10
No. of branch lets = 250 x lo= 2500
No. of flowers in a single branch let = 20
Total No. of flowers in a tree = 2500 x 20 = 50,000
Quantity of nectar in a single flower = 3267~1 = 3.25 ml
Total nectar productiorl of the tree = 50,000 x 3.25 = 162500 ml
=162.5 liters
IV.2.1.2.4. Foraging behaviour for nectar and pollen
Observations for foraging were made in the same tree in which nectar
quantification was done. The table 4 summarizes the details of bee activity
in 5 different flowers. Even though one more tree was considered for
observation, because of less number of fresh flowers, bee activity was
negligible. The detailed bee activity during the day in intensive observation is
outlined below.
6.30 AM - Pollen foraging was lacking. Bees were found to rest on anthers
but forag~ng was absent. They sweep inside and suddenly flies away.
6.40 AM - Anther dehiscence occurred.
7.00 AM - Both pollen and nectar foragers were found in one and the same
flower. Nectar foraging was found to be instant. The nectar foragers rest on
71
one of the petal side and sweeps into the nectar and flies away.
7.15 AM -Active poller~ foraging.
7.25 AM - Foraging as a whole in this tree is high. Most of the freshly
opened flowers are having bees and most of them are pollen foragers.
Random sampling of bees at this time presented varying numbers of pollen
foragers. Each flower was having 11,8,7,8,5,10 etc. numbers of bees. After
collecting the grains on the corbiculae, the bee rests on the petal and
arranges the load and flies away.
8.00 AM - 6 bees in F3, 7 bees and 1 Melipona bee in F4.
8.05 AM - 16 bees were found foraging in a single flower. F5 was having 12
bees and F4 was having 5 bees. Anthers near to the stigma were preferred.
At the peak foraging period, strong competition between bees could be
observed.
8.15 AM - On the tree as a whole, the activity was less. Only 5-6 bees were
found in the tree (random obsewation). Only the freshly opened flowers
showed active foraging. Bees were found circling the bagged flowers.
8.45 AM - (F4); One A. c. indica, visited the central anthers and spent 10
seconds.
9.15 AM - One A. c. indica came to one flower, goes inside, coming to
anther, then again goes inside and flies away. (Time 58 seconds).
9.35 AM - Fland F2 are bagged flowers and in these, the pollen grains at
the surface of the dehisced anthers are abundant. But in F3 and F4, the
surface of the anthers are absolutely devoid of pollen grains and this is
because of the voracious feeding of bees in these left opened flowers. By
9.00 AM, the pollen foraging was found to be ceased. By this time, the
temperature rises; heavy sunshine was found falling on the tree. After this a
few Meliponinae were found making glance visits and this may be for nectar
foraging. Foraging of sting less bees after the ceasing of foraging activity
may be because of the high competition offered by A. cerana indica bees.
Hence a critical observation of the periodicity of nectar production
and foraging by bees in Bombax ceiba L. indicated that the species offers
the maximum resources for the insect and bird visitors during the peak
periods of foraging. When the flowers bloom, they are full of nectar and the
production of nectar continues through out the day. The peak foraging was
found to be between 7 AM and 9 AM and this declines, as the temperature
rises. The anther dehiscence occurs at about 6.40 AM and this may also
be a reason for this peak foraging.
The observation indicates that these flowers produce nectar through
out the day so that it can offer their resources even to those small insect
visitors, which cannot compete with the active foragers. As this species is a
protandrous one, the stigma attains maturity only very late and this is also
one of the reasons for the production of the nectar through out the day.
By evening, nectar production stops and there is no further activity of
bees. The absence of foraging of honeybees between 11 .OO AM and 4.00
PM is because of high atmospheric temperature and the energy utilization
during flight at this period may reduce the efficiency of foraging.

IV.2.2. Pollen foraging and beebread production
Pollen is an essential resource for bees as it provides the proteins
required for larval development and growth. Bees typically collect pollen
from a limited subset of the available plant species, indicating that bees
perceive qualitative or quantitative differences between species. Despite
the joint requirement of nectar and pollen for survival and the concurrent
production of pollen and nectar by many plant species, bees do not often
collect pollen and nectar simultaneously. While collecting pollen bees visit
more different plant species than in nectar collection.
Plant species differ considerably in many pollen characteristics that
may influence the selective behaviour of pollen-collecting bees, including
standing crop, grain size and protein content. Bees are responsive to
variation in the amount of pollen available per plant and can be expected to
adjust their behaviour l:o collect pollen from plant with the highest standing
crop. Pollen grain size could also affect pollen value because bees use only
the protoplasmic nutrients found in pollen and discard the pollen wall.
The behaviour of bees, while collecting pollen from a single plant
species depend on foraging time and metabolic costs in a manner that is
consistent with maximization of gross pollen-collection efficiency. The
observations on pollen loads collected by native bee species have shown
the abundance of Dillenia pentagyna pollen in southern deciduous forest
zones. With this background information, an attempt has been made to
observe the pollen foraging of Apis cerana indica bees in this species.
IV.2.2.1. Pollen foraging on Dillenia pentagyna L.
Dillenia pentagyna L. (Dilleniaceae) is an important element of
deciduous forest patches of southern Western Ghats. By the end of
February the whole tree gets defoliated and all the branches simultaneously
set into bloom. Flowers are bright yellow and are fascicled on nodes of old
branches. Each fascicle consists of 3-6 flowers and the flowers are
actinomorphic and pentamerous. Stamens are arranged in two whorls and
the anthers linear dehiscing by slits.
IV.2.2.1 .I. Quantification of flower productivity
1 Inflorescence = Average 5 flowers.
lsmall branch = 22 inflorescences.
1 large branch = 112 srnall branches.
Itree = 6 large branches.
Total No. of small branches = 6x 112 = 672
Total No. of inflorescences = 672 x 22 == 14784
Total No. Flowers = 14784 x 5 = 73920 Flowers
IV.2.2.1.2. Bee activity for pollen collection
Obsewat~ons for bee activity on this species were initiated at about
6.30 AM and ceasing of foraging was recorded by 9.30 AM. Details of
foraging are outlined below;
Three different trees were selected for observations on foraging.
Dehiscence of anthers takes place even before the opening of flowers. In
mature unopened buds, anthers were dehisced. Not a single bird was found
visiting the trees. The bees were the dominant insect visitors. As the
dehiscence of anthers occurs before the opening of flowers, this plant must
be a self-pollinated one. Even though the whole tree is having intense
foraging, the time each bee spends in a single flower decreased by 7.45
AM. This may be because of the decrease in pollen forage in each flower
after the heavy foragrng. By this time the temperature starts rising and
humidity decreases. In one of the tree, three different branches were
selected for observation. The 0 b S e ~ a t i o n ~ of bee activity in three different
branches are outlined in table 5.
Buzz~ng of bees was prominent and by 9.00 AM the A. c. indica
foraging was found to be decreasing, but the Melipona bees were found
collecting pollen. This may be because of the fact that Meliponinae need
only very less amount of pollen and this might have left even after the active
foraging of A. c. indica bees. A. c. indica bees and Meliponinae were found
actively foraging for pollen between 8.15 AM and 9.00 AM. Prominent loads
were found on bee corbiculae and the colour was found to be orange red.
IV.2.3. Pollen Analysis and Biological Standardization
The study of pollen in honeys or honeybee loads is important not only
for gaining knowledge on the honey flora, but also for making an insight into
the nutritional aspects of the honeys as related to pollen grains. It is known
that the pollen constituents of the honeys is the chief source of vitamins,
mineral contents, fatty acids and amino acids in honeys and it varies with
the different pollen grains and amount of each pollen type contained in the
specific honeys. Such information will provide a new base to promotion of
apiary industry by raising the plants flowering at various times covering a

whole year and producing nectar and pollen in desirable quantities around a
specific bee colony un~t.
Of the varlous botanical problems connected with apiculture, the
more important ones are the resource identification (both for nectar and
pollen), preparation of floral calendars, toxicity to bees and detection of
botanical composition and geographical origin of honeys.
Analysis of pollen grains in honey provides information about the
geographical origin and period of honey production as pollen grains in honey
indicate the plants visited by bees. (Deodikar et a/, 1958; Chaubal, et a/,
1963; Nair, 1964; Sharma, 1970; Chanda and Ganguly, 1981; Bhattacharya
et a/, 1983). Many of the identified honey plants are important ecological
indicator types in the area of honey production (Agwu and Akanbi, 1985).
Based on the quantity of pollen grains in a given honey sample, the degree
of its purity in commercial honey can be tested. The nature of mixing native
honeys with the exotic can also be effectively judged from honey pollen
analysis.
A detailed characterization of all the honey and pollen samples
collected from different agro-ecological situations of the district with respect
to honeybee species and species preference for the nectar and pollen
requirements have been done in order to find the potential resource diversity
for the apiculture ~ndustry in this part of the state. The results showed the
presence of 58 different identified major species and 26 unidentified species
in chance occurrence. The pollen characteristics of these species are
summarized below.

IV.2.3.2. Pollen Spectra of honey and Pollen loads
Based on the above pollen characteristics, pollen combinations of
individual samples with respect to the honeybee species were worked out
and this lndlcated wide variability in resource preference and resource
sharing among the bees.
1V.2.3.2.1. Apis dorsata honey ('Thookkuthen')
The characterization Included 4 different honey samples and a pollen
load of A dorsata collected from four different localities. The details of
individual honey samples are outlined below:
93
Honey sample 32
The concentrations of pollen grains were less and a total of 14
different species were present in the sample and 11 of them were identified
up to the species level. Of which Terminalia paniculata was dominant,
Dillenia pentagyna and Lannea coromandelica were frequent and all others
were present in meager concentration. (Fig.3)

Honey sample 69
This sample has been collected from a transition zone between a
cultivated land and a forest ecosystem. The pollen concentration was more
and showed the presence of both wild, cultivated and weedy plants. The
sample harbors 6 different species and Lagerstroemia speciosa was the
dominant one. (Fig.4)

4. Helixanthera wal1ic:hiana 5. Pennisetum polystachyon 6. Type 4.
Honey sample 70
The pollen combination of the sample showed the presence of only
three different grains, of which Olea dioica and Lagerstroemia speciosa
showed more or less equal distribution. (Fig.5)

5. Type 15
Pollen load 70
The pollen loads isolated from the combs also showed the presence
of only those grains, !which were present in honey sample ie. Olea dioica and
Lagerstroemia speciosa.
Honey sample 91
The sample showed the presence of 7 different species and the
frequency of occurrence of Schleichera oleosa was far more than other
species. (Fig.6)

lV.2.3.2.2. Apis cerana indica honey ('Thoduthen')
The characterization of honey samples from this bee species included
16 samples from wild habitat, 32 samples from apiaries and 6 samples from
markets. The critical arlalysis showed variations in species preferences of
this bee in wild and domesticated habitats.
A. Wild samples
Honey sample 2
The forest zone from where the sample has been collected was near
to the cultivated land and the pollen presentation showed a mixture of wild,
weedy and cultivated species. There were 13 different species and all
frequent grains were identified. (Fig.7)

Honey sample 3
The area of collection and the period in which the sample has been
collected was more or less similar to sample 2. The bees showed
preferences for some other species also like Schleichera oleosa. This shows
that one and the same species in the same area may show different
preferences. (Fig.8)

Honey sample 5
This sample has been collected from a region where there is
abundance of exotic, introduced ornamental species, which forms a
continuous supply source of nectar and pollen. But the analysis showed a
strict avoidance of these exotic food resources and showed preferences for
native ones. (Fig.9)

The pollen analysis showed unifloral loads of Cocos nucifera, bifloral
loads of Cocos nucifera and Schleichera oleosa and multifloral loads with
Cocos nucifera and Holigarna arnottiana as dominant grains and Areca
catechu and an unidentified perforate grain as frequent ones.

B. Apiary samples
32 different apiary samples collected from different parts of the district
were analyzed for species preference of the honeybees. The colour, texture,
flavor and taste of the apiary samples do not showed much differences and
this may be due to the preference for nectar from Hevea trees. Those
apiaries, which were close to the forested highlands, were having more
species preference than those in Rubber plantations.

Analysis of pollen grains in honey and pollen loads indicated the
presence of 58 different identified species, of which 26 of them were
frequent in the samples; and about 26 species in chance occurrence with one
or two grains in each sample. Graphical representations of the frequency
distribution of the incidence of 26 major species in the honey samples are
given in Fig.67. Species having distribution in more than 10 samples are
taken for this graphical representation.
The Apis dorsata bees preferred 20 different species, Apis cerana in
apiary condition 31 species, in wild habitat 34 species, in market samples 24
species, Apis florea 15 species and Trigona irridipennis 52 species. This
shows the wide range of diversification in diet preference of Trigona
irridipennis.
The dominant species in each sample were identified with reference
slides and the details of dominance of individual species in samples are

summarized in table 6. This showed the dominance of 22 different species
in the samples. The species were listed in the order of dominance as Dl, D2
and D3. This indicates the fact that these species can offer better resources
for the honeybees and can contribute to the honey production of the district.
lV.2.3.3. Resources for honey production
The frequency distribution of the incidence of different species in the
honey samples showed that out of the 58 identified and 26 chance species,
26 of them were frequent in the samples (Fig. 67), each with distribution in
10 - 70 samples. At th~e same time the dominance of species in individual
samples (Table 6) showed 22 species as dominant ones in honey samples.
A critical analysis of the data shows that 17 species share the
dominance and frequency (Fig.68) and contribute the major resources for
the apiculture industry. Table 7 summarizes the dominant and frequent
species and contribution of the resource as nectar, pollen or both.
The difference in data in frequency distribution and dominance of
individual species shows the importance of all these 3ldifferent species in
the apiculture industry in this part of the state. Even it can be concluded that
17 species recorded both as frequent in the samples and dominant in
individual samples be regarded as the key resources for beekeeping.

IV.2.4. Species diversity and relationships in honey samples -
A Cluster Analysis
A comparative analysis of the honey samples with respect to the
frequency of occurrence of pollen grains of 58 different species revealed
inter relationships, irrespective of the honeybee species and nature of the
honey samples.
For the elucidation of the relationship and resource sharing between
honeybee species, 9Ei different honey samples of 4 different honeybee
species namely A. c. iindica, A. dorsata, A. florea and Trigona irridipennis,
where sufficient pollen representation was found were selected. The species
representation in honey samples were selected on the basis of light
microscopic analysis, their frequency distribution and relative dominance.
The cluster analysis using NTSYS-pc grouped the 95 honey samples
into 11 base clusters with 12 sub clusters having 6 individual samples
showing close affinity and 1 complex group with unique grouping of its own
with 15 samples (Fig.69).
The species preference of different honeybees in different
geographical zones grouped the samples in distinct clusters. The analysis
by three different methods namely single link, complete link and unweighted
pair group method showed distinct clustering among the samples and this
imply the inter relation between the samples and hence the resource sharing
among different honeybees.
I / P', k.-: I
Fig. 69. Unweighted pair group methad analysis (UPGMA) I . ' .
The characteristic:^ of each cluster are outlined with emphasis on the
species preference, lioneybee species and morphological nature of the
flowers visited by the different honeybee species.
Cluster 1 : (Fig. 70)
This cluster grouped 4 different wild samples of Trigona irridipennis
and one wild Apis cerana indica honey sample collected from three different
floristic locations of the study area. Clustering was between S1, S24, S82,
S33 and S26 and the sharing of nectar resources between A. c. indica and
Trigona were seen in Bombax, Lannea, Aporosa, Dillenia, Phyllanthus,
Schleichera and Dentlrophthoe. The dissimilarity coefficients ranged
between 5.701 and 8.293, maximum similarity was between S24 and S82
with a percent similar~ty of 94.299.
Cluster 2:(Fig. 70)
This is a small cluster of three A. c. indica honey samples having
dissimilarity coefficients between 4.531 and 5.909. The samples of this
cluster viz, S2 and S74 were wild collections and S92 was an apiary
collection. The resource sharing in these samples in wild and apiary habitat
were that of Mimosa, Cocos, Syzigium, Areca, Dillenia, Aporosa and Vateria.
This occurred because of two different factors. The S2 sample collected from
the forest was near to a cultivated zone of mixed crops and the apiary from
where the S92 was c:ollected was near to a forest zone in two different study
locations.
Cluster 3:(Fig. 70j
This is a complex cluster with 16 honey samples of A. c. indica bees
with 4 sub clusters. The dissimilarity coefficients ranged between 0.000 and
4.262. The grouping inc;luded 12 apiary samples, 2 market samples and 2
wild samples. This indicates the similarities in the resource preference in
apiary habitat and the possible origin of market samples from the apiaries of
the district. The grouping of 2 samples from the natural habitat indicates the
nearness of the forest to a cultivated zone. The pollen concentrations of all
these samples were meager and that showed the origin of the honey from
the extra floral nectarines of Rubber.
Sub cluster 1: This includes S3 a wild sample and S39 an apiary sample.
The species shared were Cocos, Mimosa and Terminalia. The dissimilarity
coefficients ranged between 3.576 and 4.075.
Sub cluster 2: This sub cluster includes two apiary samples S65 and S68
and a sample collected from natural wild habitat, S9. The coefficient of
dissimilarity ranged between 1.995 and 3.665. The resource sharing was
observed in Cocos, Fdirnosa and Lagerstroemia.
Sub cluster 3: This sub cluster grouped two market samples of A. cerana
indica S22 and S41 with three apiary samples viz; S47, S50 and S58. In
these cluster two-apialy samples, 550 and S58 from two different collection
localities showed 100% similarity indicating the resource specificity of A.
cerana indica. The coefficient of dissimilarity ranged between 0.000 and
3.315. The clustering of market samples along with the apiary samples
indicate the possible origin of the market honey from the apiaries where the
pollen concentration was very meager and there is dependence on extra
floral nectaries. The significant resource is the extra floral nectar from
Hevea brasiliensis and other species shared were Mimosa and Syzygium.
Sub cluster 4: This grouped 6 samples of apiary honey with dissimilarity
coefficients ranging between 0.000 and 4.262. In this sub cluster also 4
samples showed 100% similarity in species preference viz; S37 and S67,
and S52 and S53. S36 and S99 grouped in this cluster with dissimilarity
coefficients 2.521 and 4.262 respectively. All the samples showed the
preference of Cocos and Mimosa with Lannea in S36 and Syzygium in S99.
Cluster 4: (Fig. 70)
This is a small interesting cluster, which grouped one wild honey
sample of Trigona irridipennis viz; S30 and one sample of Apis dorsata, viz;
S70. The presence of (?lea dioica grains in both the samples is the reason
for grouping these in one cluster with a dissimilarity coefficient of 2.538. This
cluster indicates the preference of A, dorsata and Trigona to one and the
same resource irrespective of the nature of the honeybee species.
Cluster 5: (Fig. 70)
This includes two samples of A. cerana indica honey collected from
the apiaries of the study area, with a dissimilarity coefficient of 2.089. S34
and S72 showed the presence of Mimosa, Cocos and Olea.
Cluster 6: (Fig. 70)
This is also a major cluster, which grouped 16 samples of which 11
are A.c.indica apiary honey, 2 are A.c.indica wild, one A.c.indica marketed,
one Trigona wild sarnple and one A. dorsata sample. The coefficient of
dissimilarity ranged between 0.000 and 6.898, and the cluster include two
sub clusters and two individual samples showing similarity to these sub
clusters. These individual samples were S66 a wild A. c. indica honey and
the other S69 a wild A. dorsata sample. The preference for Cocos nucifera
is the basic reason for grouping of these samples in this cluster.
Sub cluster 1: This sub cluster includes 10 A.c.indica apiary honey samples
and one wild sample of the same honeybee. The coefficient of dissimilarity
ranged between 0.000 and 5.703. S28 and S48 showed 100% similarity
showing preference for Cocos nucifera, Syzygium cumini, Mimosa pudica,
Pennisetum polystachy12n and Hopea ponga. The wild sample that has
been collected from a transient zone between wild and cultivated species
grouped in this cluster, because of the preference of the species for Cocos
and Mimosa along with Ceiba and Aporosa. In general the apiary samples
in the cluster showed relatively less frequency of pollen grains and
dependence on species like Cocos and Mimosa.
Sub cluster 2: This sub cluster grouped two samples of A. c. indica, one
marketed viz; S16 and the other apiary honey viz; S35 and a wild Trigona
honey sample. 588. 'The dissimilarity coefficients ranged between 4.906 and
6.068.
Cluster 7 : (Fig. 70)
This includes 4 samples of A. c. indica samples, two wild S31 and
S101, and two from the apiaries, S86 and S54. These apiary samples from
Kulathupuzha and Kottur showed wide preference in resources, as there is
sufficient availability of' these species. Because of this range in resource
preference, these apiary samples got clustered along with wild samples.
The species shared among them are Erythrina, Syzygium, Pennisetum,
Dillenia, Vateria and Holigarna. The dissimilarity coefficients ranged between
5.189 and 7.476
Cluster 8: (Fig. 71)
This cluster grouped 11 samples in 4 sub clusters and one sample
showing close similarity to these sub clusters. The dissimilarity coefficients
ranged between 4.563 and 8.838. The individual sample, which grouped in
this cluster, was an /I\. c. indica wild sample S56, with preference for Dillenia,
Careya, Terminalia, Phyllanthus, Cocos and Mimosa.
Sub cluster 1: This group includes two A. c. indica honey samples,
marketed S76 and wilcl 578, and one Trigona sample S6. The dissimilarity
coefficient ranged between 4.563 and 7.577. Resource sharing between
Trigona and A. c. iridica was observed in Dillenia, Terminalia, Helicterus,
Schleichera, Holigarna, Aporosa, Careya, Elaeocarpus, Lannea and
Syzygium.
Sub cluster 2: This sub cluster grouped S91 an A. dorsata sample along
with S98 a Trigona honey. They showed a similarity index of 94.135%.
Sharing of resources in these two different honeybees is seen in Lannea,
Dillenia, Vateria, Careya and Tinospora.
Sub cluster 3: This includes two A. c. indica honey samples, viz; S14 an
apiary collection and S93 a wild one. The clustering of a typical tribal
collection with an apiary one indicate the nearness of the apiary to a forest
zone where resource availability was more or less similar to the forest zone
from where the wild sample has been collected. Resource preferences in
these geographical zones include Terminalia, Syzygium, Dillenia,
Schleichera, Cocos, Aporosa, Phyllanthus emblica and Olea. The presence
of Cocos pollen in wild sample indicates the strong preference of A. c. indica
to this species.
Sub cluster 4: Here the clustering was between two Trigona samples S42
and S43 and one A. c. indica wild sample S19 and dissimilarity coefficients
ranged between 5.:255 and 8.365. Cocos, Mimosa, Areca, Dillenia,
Syzygium. Passiflora, ,Pennisetum and Vateria were the common species
found in these samples.
Cluster 9: (Fig. 71 )
This cluster includes 13 different honey samples, of which 9 are
Trigona honey, 3 are A. c. indica honey and one A. dorsata honey. In this
cluster, 8 Trigona honey samples clustered as a distinct sub cluster and the
second sub cluster is formed by one A. c. indica wild sample and a Trigona
sample. Along with this, two A. c. indica samples viz; S20 and S94, and one
A. dorsata sample S32 showed similarity to this cluster with a dissimilarity
coefficient of 9.575. 'These samples were grouped in this cluster because of
the sharing of resources like Dillenia, Lannea, Syzygium, Elaeocarpus,
Holigarna and Pennisetum.
Sub cluster 1: This is a compact sub cluster, which grouped 8 samples of
Trigona irridipennis. This cluster reveals the specificity of Trigona bees in
their resource preference in different localities. The coefficient of
dissimilarity ranged between 5.451 and 8.777. The species preferred were
Aporosa, Dillenia, VBteria, Pennisetum, Holigarna, Mallotus, Careya,
Syzygium, etc. An important observation was the diversity of resource
preference of Jrigorna irridipennis and each honey sample was a
combinatton of nectar resources from 13 to 16 different species and almost
all the honey samples were multi floral in origin.
Sub cluster 2: This sub cluster include one A. c. indica honey S5 and a
Jrigona sample S84. They show a dissimilarity coefficient of 9.265.
Cluster 10: (Fig. 71)
This is also a compact cluster of 6 Jrigona honey samples, with a
range in dissimilarity coefficients from 6.779 to 10.528. An important
observation is the clustering together of 5 different samples from different
locations of the same collection locality viz; Ponmudi. This confirms the
utilization of pollen analytical data to find the geographical origin of honey
samples. The specie!; preferences in all these samples were more or less
similar.
Cluster 11: (Fig. 71)
This is a small cluster with two, marketed A. c. indica samples S21
and S40 with a similarity coefficient of 89.784 (dissimilarity coefficient =
10.216). The pollen c:oncentration in both these samples were meager and
the species recorded were Syzygium, Dillenia, Jerminalia, Caesalpinia
bonduc, M~rnosa pudicca and Pennisetum polystachyon. The presence of
typical deciduous elernents like Jerminalia, Dillenia etc. and relatively low
frequency of grains indicate the chance of mixing up of honey collected from
apiaries and that from forest zones.
Unique samples: (Fig. 71)
Of the total !samples studied, 15 of them stand separately in the
clustering analysis because of the unique plant preferences of their own. The
wide range of variability was shown by S100, the A. florea honey with a
variability coefficient of 19.636. It showed a unique preference in resources,
mainly Vernonia art)orea, Leptonychia moacurroides and Bambusa
arundinacea along with 13 other species, which has been shared among
other honeybee species.
Other samples that showed wide variability in decreasing order were
S4, S23, S7, S59, S55, S81 (all Trigona samples), S46 (A. c. indica), S97,
S17 (Trigona sample), S57, S15 (A. c. indica), S12 (Trigona sample), S38
(A. c. indica) and S25 (Trigona honey). The dissimilarity coefficients ranged
between 8.881 and 118.082.
IV. 3.Dietary preference ofApis cerana indica F .
Pollen grains provide the proteins needed for the larval growth and
development among the bees. Even though the pollen forage covers a wide
spectrum of plants, only a few species are of significance, in terms of
preference by the bees. Honeybee pollinators come across a vast
assemblage of plants to provide them food security, which include nectar
and pollen, each with it.s own value.
Despite this czornbined requirement and the concurrent production of
pollen and nectar by many plant species, bees do not often collect pollen
and nectar simultaneously. In brood-rearing insects, pollen collection for the
brood is generally more significant than nectar collection and in collecting
pollen, bees visit more different plant species than that visited for nectar
collection. The pollen constituents of pollen loads are often limited to a few
species because of species-specific nutritional benefits as known from
varying chemical cornposition of the pollen (Stanley & Linskens 1974).
Even though, bees can collect pollen from many plant species, the
pollen constituents of the pollen loads often found limited to a few species.
Such pollen preference is advantageous because bee larva could derive
essential components from certain pollen grains. Maximization of foraging
efficiency by a pollen-c:ollecting bee could result in preferences for particular
plant species by two non-exclusive reasons. First, bees may be able to
harvest pollen with less effort from a particular species, so that pollen
collection from that species is less costly. Foraging gains increases through
specialization because! individuals do not have to pay the learning costs
associated with switching between plant species (Laverty, 1994). Secondly
bees may consistently collect pollen from a particular plant because its
pollen provides some specific benefit such as the concentration of adequate
nutrients for growth.
It is therefore! imperative that natural field knowledge on foraging is
essential for the management of native bee species of any one floral unit
with potentiality in commercial apiculture. In Kerala Apis cerana indica is the
commercially exploitecl species in bee keeping. However the studies on
pollen foraging and food sources in this area is lacking and hence the
present investigation.
While laying standards for the present investigation, the critical
resource-limiting period has been chosen, since this period marks the brood
rearing season in the bee management cycle of the area under investigation.
Also the key pollen sources were identified which can help in the sustenance
of future generation. Further the dietary importance of these species was
assessed using percent composition and pollen volume in the corbicular
pollen loads.
IV.3.1. Species representation in pollen load samples
Plant species differ considerably in many pollen
characteristics and that may influence the selective behavior of pollen
collecting bees. Because of such diversity in size and morphology of grains,
they differ in the harvest ability and easy handling. Pollen grain size affect
pollen value, because bees use only the protoplasmic nutrients in pollen and
discard the pollen wall. So in calculating dietary preference of bees, pollen
grain volume is important (Buchmann, et a/, 1991).
Location based experiments are essential for the elucidation of forage
preference at a specific: location and for the enhancement of apiculture in a
particular area. Bees; have a definite capacity of perception of form, size,
colour, number, pattern, taste and smell, blended together in the form of a
definite composite memory which conditions their responses and behaviour
towards specific floral types for collection of nectar, pollen or both, with the
result that the foraging worker bees get almost exclusively confined to the
flowers of the same species or even to the same varieties.
Many pollen loads captured at the hive entrance are found to contain
few grains of 'foreign' pollen. These may have been brought to the flower by
the flies or other insects that visit flowers indiscriminately, or they may have
been scraped up frorn the alighting board in the act of capturing the pollen.
Mixed pollen loads are of two kinds, namely segregated (S) and mixed (M)
type. In the 'S' mixture, the two kinds of pollen are distinct, the bee having
started collecting frorn one plant and then changing over to another,
resulting in a load with partition coloured bands of pollen. Sometimes one
part of the segregated load consists of pure pollen of one type, while the
other is a mixture of lwo types, or a load appears differentially coloured
because, one type preponderates in one part and the second in the other. In
an 'M' type, the two kinds of pollen are mingled and the load is all of one
colour and can only be identified as mixture under the microscope. The most
potent cause of mixtures is propinquity (nearness). In a small number of
cases the constituent plants of a mixture may have been growing at a
distance apart, but in a majority they are found to have been growing
intermingled.
The number of species utilized significantly lower than the species in
flower suggesting that only some species are important (Fig 72). Average
pollen types of each hive was about 5.5 with a range from 4 to 7 the bees
used only 8 species of' the 110 flowering species available at the site, and
this confirms the selectivity of A.cerana indica for pollen resource. Most of
the foragers (84%) utilized only one floral source on each trip, thus exhibited
unifloral constancies. More than 50% of the workers transported unifloral

pollen loads of Cocos nucifera L. (Arecaceae) followed by Mimosa pudica L.
(18%- Mimosaceae) Terminalia paniculata L. (Lamiaceae - 7%).
Among the multifloral corbicular loads two types of grains were often
found (61 .I 1 %), three types in 27.77% loads and rarely four types (1 1 .I 1%).
The grains in mixed loads showed conspicuous difference in pollen
combinations. The results in table 8 show the forager's pollen on a single trip
from plants of different families with morphologically distinct flowers, and
inflorescence. Thus the analysis showed that the bees preferred
actinomorphic flowers with less complexity in morphology (75%) and the
grains, which are mostly psilate and having least ornamentation patterns.
An assessment on dietary importance in the critical resource limiting
period was made by analyzing the pollen volumes of species preferred,
correlated with pollen frequencies (table 9) Using mean individual grain
volume (n = 10) for each taxon, total pollen volume was calculated by
multiplying it with the concentration of each grain in total multi floral loads.
This was found to vary from 1.872 X cm3 to 89.79 X 10.~ cm3.
Percentage representation by slide count was significantly different from
percentages of total pollen volume by six species preferred in the multi floral
loads (fig 73).
Even though, Mimosa pudica L (Mimosaceae) represented by 57.74%
in the slide count, it c:or~tributes only 2.54% of the total pollen volume. On the
other hand the largest Cocos nucifera L. counts to 4.84% in the slide but the
species contributes the maximum pollen volume of 39.28%. The percent
pollen volume contribution in the unifloral pollen loads was more for Cocos

nucifera, followed by Hyptis suaveolens, Terminalia paniculata and finally
Mimosa pudica. As per the criterion established by Ramalho et a1 (1985), the
main sources exploited by bees are types with frequencies equal to or higher
than 10% and it was found that Cocos nucifera L., Mimosa pudica L., Hyptis
suaveolens L. and Tt?rminalia paniculata were the major sources utilized by
A. indica bees.
Though the immediate vicinity of the hive at the deciduous forest was
having an abundant flowering of Helicterus isora, Butea pamiflora and
Terminalia paniculata, the grains of Terminalia paniculata occurred very
rarely, the pollen of the other two species on the other were not collected at
all. The relative preferences to native and introduced vegetation observation
in the transient zone hive presented the results of strict avoidance of
introduced exotic pollen and instead showed a preference to native ones.
W.4. Status, prospects and pattern of Folk Apiculture
Indigenous people with a historical continuity of resource use often
posses a broad knowledge system of the behaviour of complex ecological
systems in their own localities (Gadgil, 1993). Kanikkars were nomadic
agriculturists practicing shifting cultivation and had considerable dependence
on hunting and gathering in their immediate neighborhoods. But now they
practice settled agriculture, which enables them to live in one place and
accumulate the necessities of life (Sashi, 1994). In the past 'Kanis' were
having a total forest based livelihood. Their economy was based on shifting
cultivation, collectiori of NWFPs, hunting and fishing. Because of the
restrictions rendered by Governmental policies, now they are forced to
practice permanent cultivation. Hunting and fishing are also gathering less
importance in the ecorlornic status of the Kanikkars.
Honey forms one of the major non-wood forest product, which they
depend on for their daily livelihood. The fanatic craving for honey sends men
on long gathering trip!; to collect this flavorful substance. These people are
having a tremendous knowledge on honey, honeybees, their behaviour and
uses of different h~ve based products.
IV.4.1. Honey Hunting
Kanikkars go in groups to gather honey, with each man taking his own
trail. When a honeycomb is noticed, the honey gatherer whistles twice as a
call to his companions to join him. In order to reach the place housing the
honey comb, a zigzag ladder is prepared by piecing together bamboo strips
fitted into each other, by means of sharpening one end of each strip to fit into
the successive top piece, and of tying up the nodal region of the bamboos to
the tree. In fact, after climbing up the ladder, they crawl for some distance to
reach the actual hive location.
While extracting honey from Apis dorsata (rock bees) the gatherers
climb up the tree at night, with their bodies smeared with a paste of tubers of
"Chenthikizhangu" (Zingiber zerumbet), which acts as an insect repellent to
avoid bee bite. A torch with the leaves of same plant is made for smoking
the comb, following which the honey comb is cut out, lowered to ground in a
bamboo basket tied to a rope, and the whole operation is completed with the
squeezing and collection of honey in the hollow bamboo internodes
('thencombu').
141
Honeys gather~ng from A. c. indica colonies also follow the same
procedure but are done during daytime, and further, the honey-containing
comb cells alone are cut. Collection of honey from Trigona irridipennis does
not require any smoking, as these bees are sting less.
IV.4.2. Identification and classification
The Kanikars are having a sound knowledge on honey, honeybees,
their behaviour and uses of different comb based products. They can
identify the genus Apis, as 'theneecha' by the size and comb architecture of
different species, presence of honey, banding pattern and behaviour of
different honeybees. Based on the above traits, they identify four different
bee groups and the respective honeys, namely A. dorsata (producing the
honey 'thookkuthen'), from A. cerana ('thoduthen'), A. florea ('cothen') and
from Trigona as ('cher~~then').
I. Thookkuthen (A, dorsata honey)
This honey is obtained from the colonies of A. dorsata. The combs of
these bees are see11 on parallel branches of large trees like Bombax ceiba
and Arfocarpus hirsutus. These are light loving species and are having an
attacking nature. These occur widely in natural forests. The tribes distinguish
3 distinct zones in the hive. Hive cells near to the parallel host branches
have pollen cells, middle portion is occupied by the egg and larvae and the
lower portion by honey cells. Most of the combs are having a semi lunar
shape.
2. Thoduthen (A. cerana honey)
This type of honey is produced by thodutheneecha. These people
also call these bees 'Njodiyil'. These are photophobic species and Kanikkars
identify them by their hives in the crevices of tree trunks. Here also they
distinguish honey zone, pollen zone and brood zone.
3. Cothen (A. jlorea honey)
The tribes distinguish this as the rarest species in their locality. The
hives are so small and are light loving and make the hives in the branches of
small bushy plants. They denote this honey as the king of all the honey
samples. They believe that this honey is so powerful that if one drop of this
fell into honey from other species, the same may become watery. Bees wax
from this species is utilized while preparing golden ornaments.
According to them, this honey is the most tasty one and medicinally
important. But the quantity of honey obtainable from a single hive is very
less. Moreover, very rarely these bee colonies are found in the forests.
When they locate a comb of this species they blow away the little bees and
consume the honey containing comb cells. They do not collect this honey for
marketing.
4.Cheruthen (Trigona :honey)
Cheruthen is obtair~ed from the sting less bees of the genus Trigona
irridipennis. On the basis of differences in hive architecture and honey
complexion these people distinguish two different types in this category;
1. Cheruthen: In this bee colony honey, pollen and larva are stored in
separate regions. The globular honey cells are widely separated from the
143
pollen stores. Hence low pollen content is a characteristic feature of this
honey.
2. Arakkuthen: This honey is stickier in nature. Here the pollen load and
honey are seen in intermixed cells. There is no gap between honey region
and pollen region. This honey is more dense and rich in pollen content. This
is because of the chances of squeezing out of pollen stores in intermixed
cells.
IV.4.3. Introduction of Bee keeping in tribal settlements
Many governmental and non-governmental agencies made some
initiatives for the ir~troduction of hive bee keeping in Kani settlements.
Selected members from most of the settlements were given IS1 type hives
and honey extractors for the up-liftment of these tribal community. Many of
the houses were found to have these beehives, but without proper
management. They were ignorant of the management practices for
honeybees.
In some of the settlements they were not given the extractor and
hence they squeeze the honey samples. Many people says that the hive
bees will not stay for a long time in the artificial hives and they easily migrate
to the nearby forests as most of the settlements are either nearer to the
forests or within the forests. According to them bee keeping by artificial hives
is a failure and thus implies the lack of hive management practices among
these indigenous people.
IV.4.4. Folk Apiculture of Kanikkars
Trigona irridipennis
Kanikkars are having inherent potential for the sustainable utilization
of honey. This has been signified by their traditional practices of bee
management. When they locate a natural hive of Trigona irridipennis in the
crevices of tree trunks they widen the mouth of the hive entrance by an axe.
They squeeze out honey only from the honey containing cells. They transfer
the larvae and cells; containing pollen stores into a Bamboo internode or
Areca stem, cut into two halves.
They make an entrance for the bees and the two lengthwise halves
were tied together after keeping larvae and pollen loads. They keep this
structure near to the natural hive for one or two days so that the bees get
settled down in a new host structure viz., Bamboo internode or Areca trunk.
This structure is transferred to the neighborhoods of their hut in order to
extract honey seasonally. They also keep these bees in earthen pots struck
to the mud cliffs.
Apis cerana indica .E
Kanikkars keep these bees also in wooden boxes in order to extract
honey in the next honey flow season. Here they extract honey from the
natural hive and transfer the queen bee along with few workers into the
wooden box. Before transference of queen bee, they keep some portion of
the hive cells containing larvae in the box in order to avoid the queen bee
from escaping out of the wooden box. They keep this box near to the host
tree for one or two days and then transfer it to the nearby areas of their hut.
145
IV.4.5. Honey Adulteration
Kanikkars adulterate the honey by adding the juice from the
inflorescence of 'Channakoova' (Costus speciosus). The extracted juice
from the flowering twig is added to honey and is slightly heated. Heating is
done to prevent the detection of adulteration by Costus speciosus. Honey is
also adulterated by the addition of a reddish brown resin of 'Venga'
(Pterocarpus marsupiilrn) produced from the bark, which increases the
colour concentration of honey.
IV.4.6. Use of antidotes
The leaf extracl from Dioscorea tomentosa (Dioscoreaceae),
traditionally called as "Nooli" because of the mucilaginous exudates in the
tuber, is used as an antidote against bee sting. They make a paste of this
leaf and 'Kookirithettam', the soil plowed by the earthworms, and apply it to
the affected sting area. In addition they use the extract of Zingiber
zerumbet, traditionally called as 'Chenthikizhangu', which are used as a
repellent to avoid bee sting.
IV.4.7. Traditional Uses of hive products
I. Pollen load: The poller~ loads of the hive they call 'poovu' are eaten raw
and is a delicious item far them.
2. Bees wax: The wax obtained from the comb cells of A. florea is utilized
during the preparation of golden ornaments. The wax obtained from A.
dorsata and A. cerana indica are used for the preparation of traditional
candles and also for sealing holes of utensils and mouth of bottles.
146
Kanikkars from settlements near Agastyamala use the wax obtained from
Trigona bees, during the blowing of heavy wind. During this period, they
make a fire heap and put this wax into the fire. Heavy dense fumes having a
particular smell generated from this rises up and the strength of wind get
diminished and finally ceases. They practice this regularly and found very
effective during heavy winds of January.
3. Bee larva: These tribes prepare delicious curry preparations using bee
larvae from A. cerana indica.
4. Puli: In Trigona bees the eggs are laid in globular cells. After hatching
these egg cells transform into a sour tasting substance named as puli. They
assign high medicinal value for the same and they use this against cough.
5. Honey: Kanikkars use honey for different ailments. 'Cheruthen' (Trigona
honey) is used for cough in young children. Most of them use honey as a
delicious food. Honey is used against burns also.
IV.5. Sustainable Utilization and Management of honey as a non- wood forest produc~t
Kerala is one of the smallest states in India, but produces the
maximum amount of honey. Dependency on monoculture plantations like
Rubber (Hevea brasiliensis) has reduced the quality of honey in the export
market even though it was possible to exploit the higher production
potential. In this con'text, an investigation has been made on natural forest
honey, resources with higher production potential, its potentiality as a non-
wood forest product and its role in the economy of the tribal people.
For the elucidaticln of the traditional management practices and
sustainable utilization of this NWFP, a case study has been formulated among
the indigenous tribal cornrnunity, the Kanikkars at the extreme end of Southern
Western Ghats.
IV.5.1. Honey - A unique NWFP
Out of hundreds; of non-wood forest products occurring in the whole
world, honey is unique in its origin as an intermediate interaction product of
insect-plant relation. Most NWFPs are having either floral or faunal origin. In
contrast to other NWFPs, in normal conditions, its production and extraction do
not adversely affect the species composition, population structure and
regeneration of forest ecosystems and is one of the significant aspect in which
honey extraction differs markedly from the impact of extraction of other NWFPs.
Honey being a plant-animal interaction product, the term 'sustainable extraction'
cannot be used in the same sense as to other NWFPs. Here sustainable
extraction holds a narrow meaning and extraction can be effected in such a
way, it does not destroy the host individual (honey bee) and also do not deplete
the product. Here the scientifically managed extraction itself leads to
sustainability of the product. Moreover, import of cheaper and superior
substitutes for some fi~rest products will lower the local value of the forest
product. But in the case of honey no cheaper substitutes are possible, and
hence there is no depreciation of its local value.
In most of the PdWFPs the increasing commercialization leads to
depletion of the produl:t, which may promote domestication or deforestation.
But increase in honey commercialization may lead to increased rate of
domestication, but it does not affect forest structure or its regeneration.
The vast untapped potential in this product for production is another
unique feature of honey. Here continued extraction without causing harm to the
individual colony, give chances of more production and it make the bees store
more honey. Hence it is evident that, in contrast to other NWFPs strategies for
production extraction and sustainable management of honey should be viewed
in a different context with emphasis on generation of expertise in such aspects
among forest dependent people.
IV.5.2. Marketing Channel
In Kerala, the collection of non-wood forest products (NWFPs) is
organized through 35tlifferent tribal co-operative societies and marketing is
done through the Kerala State Federation of Schedule Caste and Schedule
Tribes development co-operatives. The co-operative societies issue passes for
collection of NWFPs to individuals of tribal community and they have to sell the
collected materials only to the Tribal Development Societies. NWFPs collected
by the tribal societies are sold at public auctions. The Federation takes 5% of
the sale value as overhead charges and gives interest free advance to the
societies to meet collec:tion charges.
The honey, that has been collected by the individuals are generally sold
through two different channels, one through the Tribal Development Societies
and the other by direct marketing. Even though they prefer to sell the product
directly to the consumers, because of greater income they receive than
marketing through TDs, they have to stick to this marketing channel because of
the restrictions they impose on collection passes and marketing.
IV.5.3. Honey extraction
All the five settle~nents were situated within the deciduous zone of the
forested areas. It was found that all the people in these settlements were found
to be involved in one of the three jobs; viz. Agriculture, (AGR) daily wage (DW)
and NWFP collection. Even though agriculture is less productive, in most
settlements, more man-days are utilized for this occupation. The percentage
income derived from each occupation showed that, with respect to man-day
utilization, the income derived from agriculture is very less but for honey
collection it is more. I11c13me /man-day showed a greater index for honey
extraction against all other occupations. The amount of honey collected per
annum showed a greater variation between the settlements ranging from 21Kg
to 1460Kg.
Here honey is produced by 4 different bee species, viz. Apis dorsata, A.
cerana indica, A. florea and Trigona irridipennis. Honey collected from A.
dorsata and A. cerana intlica are marketed together. Details of extraction are
shown in table 10.
Pollen is not utilized in any of the settlements and wax has been collected
from A. dorsata colonic!; and has been sold in only one of the settlements ie.51
Kg. Honey from Trigona irridipennis is not marketed through the society, instead
they market it directly.
Critical analysis of the present status (Table1 I), it can be found that there
is maximum exploitatior~ olf honey in one of the settlements (Potomov). This is
because, here more individuals are dependent on Non-Wood forest products
and there is limited man-day utilization on less productive agriculture. The
people in this settlement clearly distinguish the productive seasons and extract
honey only during the season. They are aware of the expected income and
there is a well-established direct marketing facility in this settlement (TDs).
But in other settlements, increased literacy level leads to options for
other jobs like daily wage and this in turn created a distraction of younger
generation from forests. Most people utilize more man-days in less productive
agriculture and they lack confidence and are ignorant of available resources
and expected income. Inadequate marketing facility was the most important
factor that was found to guide their utilization of honey resource in these areas.
IV.5.3.1. Extraction Procedure
Generally, the hives of A. cerana indica and Trigona irridipennis are seen
in crevices on tree trunks. In contrast, the hives of A. dorsata hangs on
branches of huge trees like Bombax ceiba and that of A. florea on branches of
small shrubs.
Once the hives have! been located within the forest, they generally smoke
out the bees with fumes or they chew the rhizomes of Zingiber zerurnbet and
blow air into the hive. This forces the bees for a withdrawal due to the insect
repellent property of the volatile oils in the rhizomes. At times they cover the
body with juice of Zingiber rhizomes, in order to escape from the insect bite.
Then they cut honey-clontaining portion of hive and squeeze the honey and
sieves it and seal the bottle with bees wax.
IV.5.4 Indigenous Management practices
The societies with colnsiderable dependence on hunting and gathering in
their immediate neighborhoods are most likely to have accumulated long series
of historical obsewatio~ns; of relevance to sustainable resource use and
conservation of diversity. Self-regulatory mechanisms tend to evolve in such
societies, when they are faced with resource limitations. Hence in the present
extraction level itself, these people are having their own indigenous
management practices for the sustainable extraction of honey.
In an annual coloriial bee life cycle, there are three distinct stages with a
dormant period extending from June to August coinciding with the monsoon
season; brood-rearing period extends from September-November and a honey
flow season from December- May. Kanikkars clearly distinguish this seasonal
variation within the hives and there is seasonal distinction of the extractive
reserves. They extract honey only in the honey flow season. Then, while
extraction, mostly they squeeze only the honey containing cells and keep the
egg and larvae intact. This is commonly applied while extracting honey from
Trigona irridipennis. In this matter, they utilize the traditional knowledge of
distinguishing three different regions in the bee hive viz. the honey zone
(Thenada), pollen zone ~(Poovada) and the brood zone (Kunjada).
While extracting honey from Apis cerana indica colonies they practice a
traditional technique called method of placing "cherup". Here they remove the
honey containing cells for extraction of honey from the colonies in crevices on
tree trunks. After this they cover the mouth of the crevice with a stone, so that
the colony does not get migrated. By this method, they are able to extract
honey from the same hive in the next honey flow season.
After extraction of honey from natural colonies of Trigona irridipennis in
tree trunks, these tribes generally transfer the brood and pollen loads into
Bamboo internodes. They keep this for at least one day near the tree from
where the honey has been extracted. By doing this the bee colony get settled in
the new Bamboo internode, and they transfer this structure and keep near their
huts for frequent extraction of honey. That is, even without any advanced apiary
techniques, they already domesticated the Trigona and A. c. indica colonies by
transferring them from the forests for seasonal extraction of honey. This
indicates their inherent pc~tential for the acquisition of modem methods of
apiculture.
