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.
Introducing the 'Western Bean Cutworm Central' Webpage
March 8, 2019
This new webpage is designed to serve as a clearinghouse of information related to western bean cutworm biology, behavior, and management in both corn and dry bean agroecosystems.
The Biology and Management of Ear-Feeding Lepidopteran Pests of Corn in Nebraska
January 9, 2019
A guide to Identification and management of European corn borer (Ostrinia nubilalis), western bean cutworm (Striacosta albicosta), corn earworm (Helicoverpa zea), and fall armyworm (Spodoptera frugiperda).
Scouting and Treating Western Bean Cutworm
July 11, 2018
Western bean cutworm egg masses have been reported on field corn in a number of locations across the state this week. Here's what to look for in the field, treatment thresholds and recommendations.
Using Degree-Day Models to Predict Western Bean Cutworm Flights
June 21, 2018
By using a degree-day model, growers can account for the effect of temperature on insect development and approximate when certain insect stages will occur. See predicted cutworm flights and recommended scouting periods for 14 Nebraska locations.
Efficacy of Foliar Insecticide Treatments for Western Bean Cutworm in Corn
April 11, 2018
Researchers report on three years of field research in west central Nebraska where 4-14 insecticide treatments were tested under irrigated conditions.
Establishing a Western Bean Cutworm Colony in the Laboratory
October 4, 2017
The western bean cutworm is an important pest of corn and dry beans in Nebraska and is a major focus of research at the Agroecosystems Entomology Laboratory at the West Central Research and Extension Center in North Platte. Because WBC has only one generation per year, researchers are now growing their own population to use in laboratory and field studies.
Scouting and Treatment Recommendations for Western Bean Cutworm
July 11, 2017
Scouting is urged for Western bean cutworm in corn as moth flights are active and particularly heavy in south central Nebraska this week. This article includes trapping reports and recommendations for scouting and treatment.
