Control strategies to reduce the impact of the spotted wing drosophila
Annabelle Firlej
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

Using carbohydrate-balance bioclimatic modelling to develop carbaryl-free apple fruit thinning strategies
The model’s predictions will be used to calibrate the dose of a thinning agent (ANA) to be applied in two plots, one treated with carbaryl and the other without, over a two-year period.
