Watch for Aphids in Corn
July 27, 2023
Aphids cause the greatest amount of injury while they are feeding within the whorl prior to tassel emergence. Treatment may be needed if pollination is no more than half complete and more than half of the corn tassels are covered with aphids.
Degree-days for Prediction of Western Bean Cutworm Flight
June 29, 2023
Measuring the amount of heat between an upper and lower threshold to which an insect has been exposed, degree-days models can provide a high level of precision in predicting western bean cutworm peak flight.

For producers concerned about seed corn maggot, these recommendations could help reduce injury in soybean fields this year.
Scouting and Treatment Recommendations for Western Bean Cutworm
July 12, 2023
Scouting should be prioritized in fields that are at the preferred growth stage for egg-laying and/or do not have the VIP3A Bt trait to protect them from western bean cutworm injury.
Western Bean Cutworm Flight Predictions for 2020
June 17, 2020
The growth stage of corn during WBC flight is critical as moths prefer to lay their eggs on corn plants between the late whorl to early tassel stage. Survival of young WBC larvae is highest if they can feed on newly emerged tassel prior to moving into the ears.
