Western Bean Cutworm
The annual western bean cutworm peak flight appears to be subsiding in many areas but moth pressure is still rather high but mainly on a very spotty basis. High risks remain from Nebraska into far southeast South Dakota, southern Minnesota, northwest Iowa, portions of Wisconsin, and also central/northern Michigan into southern Ontario, Canada. Moderate risks continue from Nebraska into South Dakota, Iowa, Minnesota, northern Illinois, far northern Missouri, Wisconsin, northern Indiana, Michigan, northern Ohio, northwest Pennsylvania, northwest New York, and southern Ontario, Canada. There are indications that peak flight is now subsiding in Nebraska and also in portions of Wisconsin and Michigan where trap counts are decreasing and field reports are lessening. Growers should continue to monitor their fields and take any action based on what is observed in those fields as problems are spotty but locally intense.
