The spotted wing drosophila (SWD) is a particularly challenging pest for the berry sector due to its high egg-laying potential and end-of-season population explosion (near harvest time). Insecticides have limited ability to reach the larvae, which are buried in the fruit. In Québec, the battle against SWD generally involves repeated and alternating applications of insecticides that are also toxic to pollinators and, in some cases, pose significant risks to human health and the environment. The release of sterile insects is a promising and environmentally friendly pest control measure that can lessen the deleterious effects of SWD on berry crops. Furthermore, the Québec association for strawberry and raspberry producers (APFFQ) supports the development of this method as a research priority for the strawberry and raspberry sectors.
To follow up on the developmental work begun in 2014, we will
From 2018 to 2021
Pest, weed, and disease control
This project will encourage growers to adopt biological control methods and lead to reduced pesticide use.
Evaluate the toxicity of biological pesticides or repellents to control the spotted wing drosophila on everbearing raspberries grown in tunnels.

The aim of this project is to measure the potential of automated traps and extrapolate it to an apple-monitoring network.
The aim of this project was to field-test sound irrigation practices and band application of various types of fertilizers at ridging time to eliminate fertigation and increase the efficiency of fertilizer and water use under plastic mulch.
