Damage to Soybean Seeds By South American Stink Bugs

Resumen

Tests with caged soybean plants in the field near Palmira, Colombia, showed that two stink bugs which are common there in soybean fields, Thyanta perditor (F.) and Acrosternum marginatum (Beauv.), damage soybean seeds by piercing the pode. The daniage, consisting of punctures, wrinkling and staining of the seed coat and discoloration of the cotyledons, matches published descriptions of darnage to soybeans by North American and Brazilian stink bugs.
