Alert Details

Low corn earworm migration risks are in the forecast for the next couple days in association with Tropical Storm Bill as it, or its remnants, moves north through Texas into Oklahoma and Kansas. Southerly winds in advance of Bill may result in isolated moth flights especially into eastern Kansas and Missouri overnight tonight, and then across the same area but also potentially further east into Illinois tomorrow night into Thursday morning. Precipitation is also predicted across the source and risk area in association with Bill, but history has shown that some isolated moth flights may occur with such systems. Looking into next weekend, a strong cold front is predicted to push southeast through the corn-growing region and may pose a fairly widespread risk of isolated corn earworm moth flights. The risk initially is across the Plains into the western Midwest, or I-35 west and south of I-90, Friday night into Saturday and then generally east of a line from Springfield, Missouri to Chicago, Illinois Saturday night into Sunday morning. Growers should be on the alert for isolated moth flights in the next week, both in association with Tropical Storm Bill and then with the cold front next weekend.
