Abstrakt: Boll-feeding bugs (plant bugs and stink bugs) continue to be an important group of insects requiring control in cotton in the USA. In the southeastern region of the country, stink bugs are the predominant group of sucking pests important in cotton production. During 2007, research on treatment thresholds for stink bugs in the Southeast (NC, SC, and GA) using population indices (bolls injured internally by feeding bugs) resulted in data that provided limited insight into refinement of currently recommended thresholds due to low stink bug pressure. As observed in 2006, a dynamic action threshold, based on varying injury levels by week of bloom (8 weeks: 50, 30, 10, 10, 10, 30, 30, and 50%), demonstrated promising results in refinement of thresholds for sucking bugs in the Southeast by highlighting the importance of weeks 3-5 of bloom. Considering the relatively low populations of stink bugs observed during 2007 and 2006, continued research in 2008 will allow further improvement of recommendations for managing stink bugs in the southeastern USA, especially considering the potential for a belated resurgence of high populations in the near future.
