There is very little documentation on the link between the number of spotted wing drosophila captured in traps and berry crop damage and associated economic losses. The aim of this project was to gather the necessary data to determine whether trap captures can predict damage levels and yield losses in the field. Traps were installed for two years in five raspberry fields in Québec. Numbers of adults in the traps and larva in the fruit, as well as yield losses and the percentage of undamaged fruit were evaluated every week during the harvest season.

The aim of this project was to field-test sound irrigation practices and band application of various types of fertilizers at ridging time to eliminate fertigation and increase the efficiency of fertilizer and water use under plastic mulch.
The aim of this project was to test the general hypothesis that exclusion nets, when properly used, can prevent attacks by most apple pests and reduce disease incidence with no major adverse effects on fruit quality.
