Abstract
The cereal leaf beetle, (Oulema melanopusj, a serious insect pest of small grains, including oats, was detected in the eastern half of Iowa in the early 1990s. Iowa's five leading counties for oat production are located in northeastern Iowa, and field surveys were conducted in this area to document Entomology the levels of cereal leaf beetle infestations, potential impact on production, and the presence of natural enemies. Findings showed that current cereal leaf beetle numbers are too low to cause economic damage and no compelling need exists to establish a management program aimed against this particular pest
