Wheat Midge Risk Maps


Each year NDSU Extension agents collect soil samples in North Dakota to measure levels of overwintering wheat midge larvae (cocoons). These samples help indicate the risk for wheat midge (Sitodiplosis mosellana) in the coming growing season.

Below you'll find information on the wheat midge risk for the past 10 years in North Dakota.

For information on the management of wheat midge including identification, life cycle, crop damage, pheromone trapping, degree day modeling, field scouting, economic threshold, cultural methods biological control and chemical control, see Integrated Pest Management of the Wheat Midge in North Dakota.


The annual Wheat Midge Larval Survey is funded by the North Dakota Wheat Commission.
