Corn earworm migration risks are in the forecast on a nightly basis through at least early next week as a fairly persistent southwesterly wind flow pattern sets up over a good portion of the corn-growing region. Southerly winds are not expected to be particularly strong through the period, but the duration may set up some localized isolated corn earworm moth flights and potentially scattered flights in some areas. For now, Low risks are predicted west of I-35 tonight into tomorrow, and then expand east to near Lake Michigan and into Illinois tomorrow night into Friday, and finally cover much of the corn-growing region near I-90 and I-94 and as far east as the I-75 corridor in southeast lower Michigan, western Ohio, and central Kentucky. At this point in the growing season, the most concern lies with fresh market and processing growers who should continue to monitor traps and scout fields until harvest.
