Spotted Wing Drosophila (SWD), the subject of numerous publications worldwide, is a major berry crop pest in Québec. SWD sparked a literature review and the publication of a technical document in 2017 by Firlej and Vanoosthuyse that provided stakeholders with an overview of the available information on this insect.
The current project will update these documents to reflect today’s body of knowledge. This update, published by IRDA, will incorporate information from more recent scientific articles, including more than 100 scientific articles published within the past year, as well as information on new methods for controlling this insect. Along with these published updates, two video clips will be produced: one that describes methods for monitoring SWD adults and larvae, and the other that advocates best farming practices that minimize SWD infestations. This project will promote the integrated management of SWD by conveying useful tools directly to Québec’s berry growers and agronomists working in this area.

In highbush blueberry fields where stunt disease has been detected, plants that have never received nitrogen fertilizer are more vigorous and homogeneous than plants that have received nitrogen fertilizer.
Exclusion nets have proven to be effective against nearly all of these insect pests, which means that it’s possible to develop apple growing practices in Québec that are not only neonicotinoid free, but also devoid of all pesticides (including acaricides, given that mite problems are a consequence of broad-spectrum insecticide use). Although the net exclusion microsystem studied in Québec since 2012 has demonstrated its effectiveness in controlling insect pests, some issues remain to be studied before it can be unreservedly recommended. Among these are the handling times for the nets, i.e., installation/removal and opening/closing, and the system’s profitability and durability over the long haul for various cultivars.

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.
