Abstract

Stink bugs are the most economically important insect pest of soybeans in Mississippi. This study focused on several aspects of stink bug biology and management. One study examined the residual activity of certain insecticides. Rain was shown to reduce residual activity and after three days most insecticides provided very little control of stink bugs. Stink bugs complete at least one generation a year on early season hosts before moving into soybeans. A study of these early season hosts found that rice stink bug was more prevalent on grasses than the other hosts sampled. Brown stink bug was found on all hosts, while other species were not found very frequently. A third study to determine the effects of an automatic insecticide on insect populations in soybeans found that yield was not affected, but stink bug populations later in the year were lowered during the 2011 study.
