The recent resurgence of bed bugs, Cimex lectularius L. (Heteroptera: Cimicidae), has increased the demand for information about effective control tactics. Several studies have focused on determining the susceptibility of bed bug populations to insecticides. However, behavioral responses of bed bugs to insecticide residues could influence their efficacy. The behavioral responses of bed bugs to deltamethrin and chlorfenapyr, two commonly used insecticides for bed bug control in the United States, were evaluated. In two-choice tests, grouped insects and individual insects avoided resting on filter paper treated with deltamethrin. Insects did not avoid surfaces treated with chlorfenapyr. Harborages, containing feces and eggs and treated with a deltamethrin-based product, remained attractive to individuals from a strain resistant to pyrethroids. Video recordings of bed bugs indicated that insects increased activity when they contacted sublethal doses of deltamethrin. Insecticide barriers of chlorfenapyr or deltamethrin did not prevent bed bugs from reaching a warmed blood source and acquiring blood meals. We discuss the impact of these responses on bed bug control practices.
臭虫（温带臭虫，Cimex lectularius L.，半翅目：臭虫科）近期再度肆虐，这使得人们对有效防治策略相关信息的需求增加。多项研究聚焦于确定臭虫种群对杀虫剂的敏感性。然而，臭虫对杀虫剂残留的行为反应可能会影响其防治效果。本研究评估了臭虫对溴氰菊酯和氯虫苯甲酰胺这两种美国常用臭虫防治杀虫剂的行为反应。在二选一试验中，成群的臭虫和单独的臭虫都会避免停留在用溴氰菊酯处理过的滤纸上。臭虫不会避开用氯虫苯甲酰胺处理过的表面。含有粪便和虫卵且用基于溴氰菊酯的产品处理过的栖息场所，对来自拟除虫菊酯抗性品系的臭虫个体仍具有吸引力。臭虫的视频记录显示，当接触亚致死剂量的溴氰菊酯时，臭虫的活动会增加。氯虫苯甲酰胺或溴氰菊酯的杀虫剂屏障并不能阻止臭虫接近温热的血源并获取血餐。我们讨论了这些反应对臭虫防治实践的影响。
