Corn earworms will continue to be active across much of the corn-growing region in the next week especially given the active weather pattern predicted. Moderate corn earworm migration risks are in place tonight mainly across portions of Missouri, Illinois, Michigan, Indiana, Kentucky, Ohio, and portions of southwest Ontario, Canada as a cold front moves southeast through the remainder of the corn-growing region. Southwest winds in advance of the front and precipitation expected near the front may provide a corridor for insect drop-out especially across the Moderate risk area tonight into tomorrow morning. Low risks are in place for Saturday night into Sunday morning primarily south of I-90 and west of US 65 across portions of the Plains into the western Midwest as the next weather system develops in the Plains. As this system strengthens, south to southwest winds should increase and a Moderate corn earworm migration risk is predicted for Sunday night into Monday morning across portions of South Dakota, Nebraska, Kansas, Minnesota, Wisconsin, Iowa, Illinois, and Missouri. Another cold front should sweep east through the corn-growing region next week, shunting the primary migration risk to the east.
