Description

The apple leafcurling midge (ALM), Dasineura mali (Kieffer), is a new apple pest in Québec. Its impact on the growth and future yields of young apple trees is still little known. 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.

Objective(s)

  • Assess the annual and cumulative impact of ALM infestations on the growth and yield of young apple trees in the establishment phase
  • Monitor the abundance of ALM adults in relation to infestation levels in commercial orchards in three apple growing regions
  • Model adult populations and develop a variable economic injury threshold

From 2014 to 2017

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.
