To maintain and enhance environmental and health gains, this project will develop a strategy for biological control of the obliquebanded leafroller in orchards where mating disruption is being used against the codling moth.
The initial phase of the project will involve fine-tuning applications of the parasitoid Trichogramma minutum so that releases to control OBLR are uniform and cost effective.
In the second phase we will assess the obliquebanded leafroller populations in a number of Québec orchards.
In the third phase we will compare three strategies for controlling the obliquebanded leafroller that combine crop practices, a Bacillus thuringiensis var. kustaki (Bt) insecticide, and the inundative release of Trichogramma minutum into commercial orchards already using mating disruption against the codling moth.

A cropping system based on adding organic matter through soil amendments and organic fertilizers can restore soil health and strawberry yields by limiting the occurrence of disease symptoms.

An attract and kill technique to control plum curculio was recently proposed by U.S. researchers, but it is very little used in orchards and virtually unknown in Québec.
