Interpretive Summary: The wheat stem sawfly, Cephus cinctus Norton (Hymenoptera: Cephidae), is a major wheat pest in North Dakota and the northern Great Plains causing significant yield and quality losses. Damage is caused by larval feeding within the stem. Wheat stem sawfly management includes the selection and use of resistant cultivars and a variety of cultural practices including tillage and swathing. Biological control provides variable and inconsistent control and pesticides are generally too costly and ineffective to be utilized. Pest management decision making requires knowledge of pest population densities and protocols for monitoring pest population dynamics by producers. This extension bulletin provides producers with mangement options for the wheat stem sawfly in North Dakota.
