FRESAPROTECT AND BERRYPROTECT

MIXES OF PARASITOIDS TO CONTROL ALL COMMONAPHID SPECIES ON PROTECTED SOFT FRUIT CROPS.

PRODUCTS DEVELOPMENT AND CASE STUDIESFROM THREE YEARS OF EXPERIENCE

IOBC VIII Workshop on Integrated Soft FruitProduction: 26-28 May 2014

Introduction

• Aphids: major pest in protected soft fruit

crops

• Chemical protection becomes more difficult (less active substances, multiresistance, health and

environnemental issues, consumers demand, less

residues, sustainable use directive)

→IPM with Parasitoids (Braconidae and

Aphelinidae)

• Viridaxis: company founded in 2004

specialized in aphid parasitoid production

• In 2007, Viridaxis started the

development of FresaProtect to facilitate

the implementation of biological aphid

control in strawberry production

• → ideal for IPM beginners

Two successful strategies:

After a chemical clean-up

Start at planting or beginning of the growth and after inspection of the crop.

First release often done too late!

• Different crop systems

FresaProtect

BerryProtect

• Cocktail of different parasitoid species (5 in

BerryProtect – no Ephedrus cerasicola)

• Main problem in raspberries: Amphorophora

idaei = virus vector (can cause up to 70% loss

in harvest), excellent parasitism through

Praon volucre

• Main problem in blueberries: Ericaphis

fimbriata (high resistance towards pesticides),

excellent parasitism through P. volucre.

• Both in raspberries and blueberries, difficulty

to reach the aphids with contact insecticides

in a dense canopy

Some case studies

PC Hoogstraten 2013FresaProtect in a elsanta crop (table top, unheated tunnel, 1000 m²).

Aphids: Acyrtosiphon malvaeMummies: Aphidius

• Start clean

• Aphids under observation threshold

most of the time

• Immediate control of all appearing aphids

PPK 2013FresaProtect in a candiss June bearer crop in plain soil (200 m²).

Aphids: Chaetosiphon fragaefolii, Acyrtosiphon malvae and Macrosiphum euphorbiae

Mummies: Aphidius, Praon and Aphelinus

• Start after a clean up treatment

• Good control of all appearing aphids

with all parasitoid species

• No economic damage

Treatment

First release clean crop

Thiaclopridagainst capsids

New release after waiting time of the treatment

Aphids (Amphorophora idaei) presents, Mummies observed regularly

Summer pruning and clean up treatment (spidermites)

Aphids present as single individuals, mummies regularly seen

A mix of parasitoids covering all commonlyfound aphids in a crop is a viable alternativeto chemical pesticides.

This concept, in conjunction with an easyapplication system, has gained the trust of growers and farmers involved in trials or usingFresaProtect or BerryProtect for theircommercial cultures.
