Management practices for wheat midge, Sitodiplosis mosellana (Géhin).
Wheat midge is an established insect pest in most wheat-producing regions of the world. It was first detected in western Canada in the early 1900’s. However, the first major outbreak in Saskatchewan was not recorded until 1983. Since then, wheat midge populations have spread and now infest a large portion of the wheat-producing area of the prairies. Damage caused by larval feeding on kernels can reduce crop yields and lower the grade of harvested grain. Today, wheat producers in western Canada have access to one of the most comprehensive management programs of any insect pest of field crops. Forecasts and risk warnings, monitoring tools, cultural control, agronomic practices, chemical control, biological control and host plant tolerance are all available for producers to manage wheat midge and to conserve its natural enemies.
