Corn earworm migration risks return to the extended portion of the forecast as south to southwest winds are predicted to return to a good portion of the corn-growing region by late in the weekend and into next week. Corn earworm moth captures across the southern and mid-south regions of the country are running at or above average for this time of year, and may also indicate that the first generation of this particular insect that can affect the corn-growing region may be ready to move north given a favorable weather pattern. High pressure is expected to hold through the early portion of the weekend so no risk is in place through Sunday morning. Low migration risks, however, are in the forecast starting Sunday night into Monday mainly from Kansas and eastern Nebraska through Iowa, Missouri, far southern Wisconsin, and much of Illinois with the risk then spreading north and east into Michigan, Indiana, and Ohio by Monday night into Tuesday. Growers are advised that while the first generation of moths does not directly harm the crop given the present crop stage, the second generation that results from the first may be a threat later in the growing season. As a result, growers are advised to monitor trap counts over the next week especially if included in the risk area.
