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.
Avoiding Injury from Seed Corn Maggot
April 7, 2021
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 13, 2022
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.
CW Podcast: Late-Maturing Crops and Insects
September 13, 2019
In this month’s CropWatch Podcast Extension Educator Michael Sindelar is joined by entomologist Robert Wright to discuss insect issues in late maturing corn and soybeans.
Western Corn Rootworm Beetles Emerging, Time to Scout
July 7, 2020
Western corn rootworm beetles began emerging in southeast and south central Nebraska at the end of June. Beetles emerge somewhat later in northeastern and western Nebraska.
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.
