What is the problem?

“The gaping hole in the toolbox for future control of Queensland fruit fly, no matter what form it takes, is the absence of an effective attract and kill lure for female flies.”

Andrew Finlay, Chairman, Summerfruit Australia

Female lure developedMilestone R2.1.9

NEXTPHASE

PBCRC 3152

To deliver a commercially viable device that traps female Qfly in the field.

PRIMARY AIM OF PROJECT 3152


What are we doing about it?Step 1: Do fruit odours attract female flies?

• Blends containing fruit ripeningvolatiles attract female Qfly

Proof of concept

11V


What are we doing about it?Step 2. Designing a more complex lure

?

Aggregation volatiles

Microbial volatiles

Deterrents

aromatics

esters

LURE DEVELOPMENT FIELD TRIALS


What are we doing about it?Step 3. Transforming technologies for designing lures

Excitation patterns in the antennal lobe provide information on how odours are percieved

ethyl propionate z-3-hexenyl acetate

acetoin Qfly brain

Reading the insect brain (antennal lobe imaging)


How will this research be delivered?

• A field effective female lure

• Possibility for patenting

• New technologies in lure design


Who will benefit from this research?

Commercial fruit growers / consultants Monitoring / surveillance Reducing Qfly damage Lowering within / between season populations Reducing urban Qfly populations

Sterile Insect Technique Assessment of success Lowering populations

Scientists Olfactory research Developing new technologies for pest management


Benefit for our horticultural industries

• Reduction in production losses (improved control of Qfly) • Improved profitability and market access for horticultural

industries


Future

A field effective female lure is the starting point

… integration into Qfly control practices… more powerful attractants

… better traps
