The swede midge has been the main pest of crucifers (cabbage family) in Québec since 2003. Its presence throughout the season, the difficulty of detecting the damage it causes, and its cryptic behaviour make controlling this pest very complicated. Organic producers currently rely on pest exclusion nets, which are expensive to use. It is important, therefore, to develop other effective ways of controlling this pest.

By enhancing our understanding: 1) of the nitrogen supply dynamics associated with the use of mixed green and farmyard manure applications, and 2) of the timeline of nitrogen uptake by garlic; we hope to fine-tune fertilization strategies so they meet the needs of garlic crops, while minimizing phosphorus accumulation and nitrogen leaching.

This project aims to develop mass trapping strategies to keep damage caused by the striped cucumber beetle populations below the economic threshold, while minimizing the capture of pollinators and natural enemies.
