A favorable weather pattern for corn earworm migration is expected to continue across portions of the corn-growing region in the next couple nights. A cold front is expected to push from northwest to southeast through the region with south to southwest winds persisting to the east. Precipitation along the front may serve as a region of insect drop out. Moderate migration risks are predicted tonight into Saturday morning across sections of Kansas, Nebraska, South Dakota, Minnesota, Iowa, Missouri, Wisconsin, and Illinois. As the cold front pushes east Saturday into Sunday, the Moderate risk area shifts to the east as well and includes fields in eastern Kansas, Missouri, Iowa, southeast Minnesota, Wisconsin, Illinois, southwest Michigan, Indiana, and western Kentucky. Only a Low risk is predicted late in the weekend into early next week to the east of I-57 in Illinois as the front moves out of the corn-growing region. Growers with crops still at susceptible stages to damage (especially the fresh market and processors) are urged to monitor their fields closely over the next several days to week as corn earworms may make or increase their presence in fields by that time.
