Corn earworm migration risks appear rather limited this week as northwest flow should dominate the weather pattern across much of the corn-growing region. There will be, however, some Low risks especially across the Plains states where more focused yet overall light southerly winds may occur. Some isolated corn earworm moth flights will be possible from Kansas and western Missouri north into Nebraska, western Iowa, southern South Dakota, and into southwest Minnesota tonight into tomorrow night. No risk is predicted tomorrow night into Thursday morning, but Low risks then return the Plains states and eventually further east into Minnesota, Iowa, and Missouri by the middle of the weekend. Growers all across the corn-growing region, however, should be monitoring traps and scouting fields as some corn earworm flights have occurred as a result of the favorable weather pattern that was in place last week and this past weekend.
