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.
