GRAND FORKS, N.D. (AP) — Grasshoppers are not doing as much damage in the Upper Midwest as officials had feared. A federal study of adult grasshoppers last year concluded that the pests could be a threat this summer in much of the region, particularly in Montana and South Dakota. Warm, dry conditions last fall extended the grasshopper egg-laying season, and the mild winter was kind to the insects. Officials feared that drought this summer would further boost grasshopper numbers. But Gary Adams with the federal Animal and Plant Health Inspection Service tells Agweek that the situation isn't as bad as expected. He says the reason is unclear but disease might play a role. South Dakota State University says grasshoppers in eastern South Dakota haven't reached the level to economically justify spraying pesticides on soybeans.
