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.

Compared with insecticide applications, this method reduces the risks to human health and the environment.

The aim of our project was to increase the acreage on which mating disruption is used against the codling moth in all of Québec’s apple-growing regions.

The main aim of this project is to test a bacterial detection technique developed in Austria that consists of quantifying inoculum carried by bees.

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.
