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.

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.

The western bean cutworm is a pest of corn and dry bean. Typically, control is achieved by pyrethroids or transgenic traits. However, control with pyrethroids may prove difficult and transgenic traits are not available for dry bean. Biological control may prove to be a useful tool for growers of both crops.

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.
