Heavy populations of immature grasshoppers were found in field borders in south central Nebraska corn fields this week. Scout and if numbers warrant, treat now when they're small and concentrated in borders. See story for identification tips, treatment thresholds, and control recommendations.
Scouting and Treatment of First Generation European Corn Borer
June 12, 2018
While European corn borer numbers have greatly decreased regionally since the introduction of the first Bt corns, local populations may still cause damage on untraited corn such as popcorn or white corn or in field planted to non-BT corn to take advantage of lower seed costs. These fields should be scouted now.
Burrower Bugs in Soybeans

Video: Populations of wheat stem sawflies, a serious pest of wheat in western Nebraska, are at high numbers this year. Surveys are underway in wheat fields, grasslands and pastures to evaluate grass hosts for the pest and its parasitoids.
Insect Light Trap Data Available for 3 Sites

UNL Extension Entomology is monitoring crop insect pests (primarily moths) using black light traps at the Haskell Ag Laboratory near Concord, the South Central Ag Laboratory near Clay Center, and the West Central Research and Extension Center near North Platte.
Scout Emerging Corn for Insects; Don't Take Protection for Granted
May 16, 2018
As corn begins to emerge, be alert to the potential for damage from early season insects such as cutworms, wireworms, white grubs or wheat stem maggot. Seed treatments provide some protection, but can be overwhelmed in some circumstances, allowing losses.
