Emerald ash borer (Agrilus planipennis Fairmaire, Coleoptera: Buprestidae [EAB]) is an invasive forest pest introduced to North America from Asia most likely in the mid-1990s. Since its introduction, EAB has caused significant mortality in North American ash (Fraxinus spp.). In national survey protocols, the week of initial EAB emergence is typically defined as the accumulation of 450 growing degree days (base 50). Twenty sites were selected in six states (Indiana, Kentucky, Michigan, Missouri, Ohio, West Virginia), nine standard EAB plastic panel traps were deployed at each site, traps were checked bi-weekly, and ten EAB female and male individuals were sub-sampled from each total trap capture for each trap check. Individual body length and mean trap check body weight were measured.
