Scouting and Treatment Recommendations for Western Bean Cutworm
July 8, 2020
The first western bean cutworm moths were captured in University of Nebraska-Lincoln black light traps June 23 at North Platte, June 26 at Clay Center, and July 7 at Scottsbluff.
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.
Spring Miller Moth Invasion
May 26, 2020
During the daylight hours the army cutworm moths seek shelter in cracks and crevices including those found in houses and other buildings. The moths begin to emerge from these locations at dusk to resume their feeding and westward migration.
Scouting Advised for Alfalfa Weevil
May 6, 2020
Alfalfa weevils have been reported damaging alfalfa in north central Kansas. As temperatures warm up, expect to see alfalfa weevil larvae in southern Nebraska and slightly later, in northern Nebraska.
Army Cutworm Scouting Urged in Western Nebraska Wheat and Alfalfa
March 27, 2020
Army cutworms have been spotted in Kansas and Nebraska crop fields this month. This is an important time to scout for this pest, particularly in wheat and alfalfa.
Painted Lady Butterflies Are Abundant In Many Areas—What Now?
July 10, 2019
Treatment is not recommended for the painted lady butterfly currently being seen in high numbers and could endanger beneficial insects. Treatment thresholds offer guidance for treating feeding caterpillars.
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.
First ECB Resistance to Bt Corn Reported in Canada
May 22, 2019
The first case of field-evolved resistance of European corn borer (ECB) to Bt transgenic corn has been reported in Canada. What does this mean for Nebraska corn farmers and how can they help maintain resistance here?
