Description
The goal of the project is to select a strain of the mullein bug to control two spotted and red spider mites from July to August (period when populations tend to explode).
Objective(s)
- Select a voracious strain of spider mite predator through isogroup selection
- Field test minimum mullein bug introduction rates required to keep spider mite populations below the economic threshold
- Determine how long the predators stay on apple trees and how effective they are
- Improve mass rearing techniques by testing two food sources and two host plants
From 2016 to 2019
Project duration
Fruit production
Activity areas

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.
