Populations of immature grasshoppers are being reported in areas bordering crop fields in several parts of Nebraska. If these grasshopper species are one of the four major species that are likely to infest cropland, control may be warranted if high numbers are present.

Potato leafhoppers have the potential to injure alfalfa in Nebraska every year and have been reported recently in southeast Nebraska. Generally they are a second and third cutting pest.

UNL Extension Entomology is monitoring crop insect pests (primarily moths) using black light traps at university facilities at North Platte, Clay Center, Mead and Concord.
