Description

The spotted wing drosophila (SWD), Drosophila suzukii (Matsumura) (Diptera: Drosophilidae), a new berry pest, appeared in Québec in 2010. Damage to unprotected fruit can reach nearly 100%. The project consisted of sterilizing the pest in the laboratory and mass releasing it in crops as a biocontrol method.

Objective(s)

  • Evaluate the potential of sterile insects as a new biocontrol method for spotted wing drosophila.
  • Develop a sterilization protocol for D. suzukii
  • Evaluate the competitiveness of D. suzukii males irradiated in the laboratory under semi-natural conditions.

Service

This project will lead to better control of the spotted wing drosophila, the country’s most devastating berry pest, which first appeared in Canada in 2006.

Using multitask nets and mechanization to eliminate pesticide use in apple orchards

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.
