Description
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.
Objective(s)
- Adjust the parasitoid (Trichogramma minutum) application method used in inundative releases to control the obliquebanded leafroller.
- Compare three strategies for controlling the obliquebanded leafroller that combine crop practices, a Bacillus thuringiensis var. kustaki insecticide, and the inundative release of Trichogramma minutum in commercial orchards using mating disruption against the codling moth.

Investigating key physicochemical and environmental factors that could account for variable lowbush blueberry yields
As part of this project, the soil water status at a chosen blueberry farm will be monitored at 40 spots over the course of the production year. We will seek to identify the relationship between water extraction, physicochemical and environmental factors, and yield levels that could help explain yield variability.
