Hessian Fly

Hessian Fly Identification and Management

Hessian fly maggots and pupae feed on tillers in the fall and winter causing wheat to thin as the infected plants die. Maggots or pupae can be found at the base of the stems, inside the leaf whorl. If the pupae survive into the spring, they can reinfect the crop and cause lodging.

Variety resistance in 2014 and 2015, rotation, planting date, insecticidal seed treatments, and foliar insecticides can be effective controls. See Biology & Managment of Hessian Fly for details.
