Description

This project’s goal is to develop a large-scale inundative release method using the same trichogramma species employed in a previous project. More specifically, we will compare two large-scale release systems administered at different doses. We will perform a cost-benefit analysis to determine which method is most cost-effective for producers and compare it to existing insecticide treatment methods.

Objective(s)

The overall objective is to develop a biological method for controlling the black-headed fireworm using trichogramma. The method will be made available to Québec cranberry growers as an alternative to insecticides. The specific aims are to

  • develop a release method with low mortality and low loss in the trichogramma system;
  • compare the effectiveness of two large-scale release methods;
  • compare two doses of trichogramma; and
  • perform a cost-benefit analysis of the two proposed methodologies and compare the better of the two against existing insecticide treatments.

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.
