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
