This gall midge is a serious pest of oilseed rape (''Brassica napus'') in Europe. The females lay eggs into developing pods and the larvae feed on the inner pod wall and secrete enzymes, causing the pods to turn yellowish, swell and deform. Yield losses can exceed 50%. Alternative hosts are turnip rape (''Brassica rapa'' subsp. ''oleifera'') , cabbage, radish, and some cruciferous weeds. Management involves usually the application of pesticides. | This gall midge is a serious pest of oilseed rape (''Brassica napus'') in Europe.

This gall midge is a serious pest of oilseed rape (Brassica napus) in Europe.
