As fields are being scouted for second-generation bean leaf beetles, stink bugs are being found in greater abundance than usual during late summer. These stink bugs are unlikely to cause any economic damage (i.e., damage that would justify an insecticide application). There are three species of stink bugs that are fairly common in Iowa soybean: the green stink bug, brown stink bug, and spined soldier bug. The green stink bug and brown stink bug are both pests and can damage pods. See the August 20, 2001, ICM article on page 121 for information on the green stink bug and damage to soybean.
