In collaboration with apple advisors, we will continue to implement the use of mating disruption against codling moth across Quebec. To do this, we will organize and carry out training and information activities for advisers and apple growers. We will also offer agronomic support for the use of the mating disruption control method in orchards.
Data on CP harvest damage and codling moth insecticide applications and associated risks will continue to be collected. They will be incorporated into the results of project PV-3.2-2015-004, entitled "Large-scale use of mating disruption against the codling moth (Cydia pomonella) in Quebec orchards" and the results of the previous mandate in order to have an environmental portrait over more than 7 years.
The mandate consists of coordinating and consolidating the use of the codling moth mating disruption control method. The objective is to increase the percentage of adoption of codling moth mating disruption, in number of apple orchard businesses in Quebec or in areas in production, to 35% at the end of the first year, to 40% at the end of the second year and 45% at the end of the mandate.

Exclusion nets have proven to be effective against nearly all of these insect pests, which means that it’s possible to develop apple growing practices in Québec that are not only neonicotinoid free, but also devoid of all pesticides (including acaricides, given that mite problems are a consequence of broad-spectrum insecticide use). Although the net exclusion microsystem studied in Québec since 2012 has demonstrated its effectiveness in controlling insect pests, some issues remain to be studied before it can be unreservedly recommended. Among these are the handling times for the nets, i.e., installation/removal and opening/closing, and the system’s profitability and durability over the long haul for various cultivars.

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.
