Description

The spotted wing drosophila, Drosophila suzukii, is an exotic pest from Asia that was observed for the first time in Québec in 2010 and has been considered as a major pest since 2013. Our project aims to promote a biocontrol solution by testing a complex of natural enemies that attack the pest at different development stages.

Objective(s)

Delay pesticide treatments for the spotted wing drosophila
Test the efficacy of predators and parasitoids against the pest in the laboratory
Test different combinations of natural enemies under semi-natural conditions
Determine the effect of biological insecticides used against the pest on the selected natural enemies

From 2016 to 2019

Project duration

Fruit production

Activity areas

Pest, weed, and disease control, Organic farming

Services

Drosophila sterilization lowers the need for pesticide applications on ripe fruit.

Attract and kill strategies for control of the plum curculio in conventional and organic apple orchards

An attract and kill technique to control plum curculio was recently proposed by U.S. researchers, but it is very little used in orchards and virtually unknown in Québec.
