Low corn earworm migration risks remain in the forecast for the next two nights as a cold front and associated low pressure systems move across the corn-growing region. The risks will focus mainly east of I-35 from northern Missouri, eastern Iowa, and southeast Minnesota into southwest Ontario, Canada and western Ohio as one wave of low pressure and a cold front push further to the east from the Plains states tonight into tomorrow morning. Low risks mainly focus from Illinois and southeast Wisconsin eastward tomorrow night into Saturday morning as a second wave of low pressure moves northeast along the same front. Precipitation along/east of the front may limit the overall migration threat, but growers located especially in the Great Lakes region should monitor for some new moth arrivals this weekend. No additional risks are in the forecast through Monday, but Low risks re-enter the forecast by Monday night and Tuesday morning mainly to the west of a Saint Louis, Missouri to Green Bay, Wisconsin line as the next low pressure system begins to develop in the northern Plains and southerly winds increase. Growers with crops still at susceptible stages to damage, most notably in the upper Midwest and Great Lakes regions, should continue to monitor traps and scout fields as some new migrants may have or could enter these fields in the past or future few days.
