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.
Using Degree-Day Models to Predict Western Bean Cutworm Flights
June 21, 2019
With late planting, slow emergence, and cooler summer temperatures affecting corn development, will corn be spared from western bean cutworm damage in 2019. Unfortunately, models indicate WBC growth is also delayed. See a table of predicted dates for 2019 WBC flights in Nebraska and surrounding states.
