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.
From 2014 to 2017
Pest, weed, and disease control
This work will help apple growers control new pests more effectively.

Biological control of the obliquebanded leafroller in orchards where mating disruption is being used against the codling moth.
An attract and kill technique to control plum curculio was recently proposed by U.S. researchers, but it is very little used in orchards and virtually unknown in Québec.

IRDA drew up a list of insects and mites in Québec known to be or likely to become resistant to pesticides.
