European Corn Borer (ECB), Ostrinia nubilalis, (Lepidoptera: Crambidae) is an economic pest in corn, Zea mays L., as well as other crops in the U.S. Populations of ECB have declined since the introduction and widespread adoption of corn hybrids expressing Bacillus thuringiensis (Bt) toxins. Our goal is to monitor ECB flights to determine adult emergence for the different voltinism and biotypes in North Dakota. Two modified Hartstack wire traps were placed in grassy ditches along corn field edges in the major corn producing areas of North Dakota. Traps were monitored weekly for moths from early June to mid-August at multiple field sites from 2018 to current field season (2022). Trap data from North Dakota will be summarized and used to validate the Midwest degree-day model for ECB emergence
