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

IRDA will select a strain of mullein bug to control two-spotted and red spider mites, two major apple pests.

Adding organic matter and biostimulants to restore and maintain soil health and yields in a matted row strawberry field with a history of decline

The objective of this project was to determine whether the addition of two types of organic fertilizers or biostimulants would produce more vigorous plants less subject to decline.

Variable economic injury for the apple leafcurling midge and modelling of population abundance of this emerging pest

The apple leafcurling midge is a new apple pest in Québec. The aim of the project is to explore the pest’s phenology, establish variable economic injury thresholds, and incorporate the results into a phenology model in CIPRA.
