The wheat midge (Sitodiplosis mosellana) is found in most areas around the world wherever wheat is grown. In recent years, significant damage to wheat crops due to wheat midge has been reported in Alberta, Saskatchewan, Manitoba, southern British Columbia, Minnesota, North Dakota and Idaho. Although this midge also attacks other members of the grass family, infestations on these plants are usually not serious enough to warrant control.

Find out about this midge’s lifecycle, crop damage, control, monitoring and best management practices.
