Low corn earworm migration risks are in the forecast mainly across the southern Great Lakes and eastern corn-growing region both Thursday and Friday nights. A corridor of south to southwesterly winds is expected to set up east of a low pressure system and trailing cold front mainly east of the Mississippi River by that time. Isolated early-summer moth flights may occur east of I-55 in eastern Illinois, Indiana, Kentucky, Ohio, southern lower Michigan, and into far southern Ontario, Canada. The main concern at this point is with sweet corn and other vegetables that would be at a growth stage that would serve as a host and/or food source.
