Alert Details

Western bean cutworm emergence is expected to continue across virtually all of the corn-growing region in the next five days as heat unit accumulations continue to rapidly climb with the above average temperatures in place. High development/emergence risks remain in place from southern Nebraska and far northern Kansas east into portions of Iowa and Missouri where heat unit accumulations are the greatest. Moderate risks are predicted from Nebraska and Kansas as far east as Ohio by the end of the five day period. Low risks extend north into South Dakota, Minnesota, Wisconsin, and much of lower Michigan by early next weekend. Trap counts across the corn-growing region are showing increased consistency in nightly catches especially in Nebraska, Iowa, northern Illinois, and even into lower Michigan and Ohio with the highest catches being reported in southern Nebraska and portions of Iowa.
