Degree-days for Prediction of Western Bean Cutworm Flight

June 21, 2022
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.

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.

Novel Strategies for the Management of the Western Bean Cutworm

January 22, 2020
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.

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.
