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

Pest, weed, and disease control

Service
