(Euschistus servus) A brownish, medium-sized member of the stink bug family (Pentatomidae) that usually undergoes a generation on hosts, such as corn and other grass species, before moving into cotton, often during boll formation. Feeding by adults and large nymphs with needle-like stylets, often on bolls of all sizes, causes small, rounded, dark spots on the exterior carpel wall; feeding can transmit hardlock organism, resulting in unharvestable bolls and low-quality lint. Brown stink bugs are more difficult to control with pyrethroids than green stink bugs. This species’ life cycle (egg to adult) typically takes 40 days.
