The southern chinch bug, Blissus insularis, is the most damaging insect pest of St. Augustinegrass lawns in the southeastern United States. Turfgrass managers and homeowners tolerate little damage, so control has traditionally consisted of periodic preventive insecticide applications. By developing a laboratory colony of southern chinch bugs, more is currently being learned about its basic life cycle. Little is known about the importance of natural enemies, or how to effectively release or conserve their populations in southern lawns. Based on laboratory tests, the big-eyed bug, Geocoris uliginosis, can attack all life stages of chinch bugs. Its ability to survive different rates of insecticide (bifenthrin, carbaryl, and imidacloprid) treatments is currently being assessed, as well as the effect of chinch bug diet (five different St. Augustinegrass cultivars) on predation and predator survival. Other environmental factors which may impact southern chinch bug populations include the amount of irrigation or fertilization used, or soil/thatch temperature.
