Abstract

Each summer since 1994, a few soybean fields throughout Iowa have been attacked by imported longhorned weevils. This insect is typically a minor pest, but serious defoliation can occur when the beetles concentrate in border rows or spots in a field. Problems typically appear in mid-June and early July. The weevils are almost always associated with grass, either following set-aside ground or dispersing out of adjacent pasture. The weevils can strip all the leaves from V5 or smaller soybean plants, but older plants apparently produce leaves faster than the weevils can defoliate them.
