Description

The bean leaf beetle is an annual pest of soybean in Iowa. Adults feed on aboveground plant parts and are especially fond of soybean pods late in the growing season. Larvae, which are similar in appearance to com rootworm larvae, feed below the soil surface on soybean nodules, but their impact on yield or plant health is not known. In addition to the physical injury that bean leaf beetle adults cause to soybean plants, this insect also transmits bean pod mottle virus-a potentially yield-robbing plant disease that makes proper management of this insect even more critical. This paper focuses on the performance of insecticides in controlling this pest.
