Infestations of the bed bug, Cimex lectularius L. (Heteroptera: Cimicidae), are increasing around the world at an alarming rate and have become a major public health concern. The evolution of insecticide resistance could be a primary factor in explaining this resurgence. Extremely high levels of resistance to two pyrethroid insecticides, deltamethrin and lambda-cyhalothrin, relative to a susceptible colony, were detected in populations collected from human dwellings in Kentucky and Ohio. Offspring of a cross between a resistant and susceptible colony had intermediate susceptibility. Evaluations of populations from across the United States indicate that resistance to pyrethroid insecticides is already widespread. Without the development of new tactics for bed bug management, further escalation of this public health problem should be expected.
臭虫（温带臭虫，Cimex lectularius L.，半翅目：臭虫科）的侵扰正在以惊人的速度在全球范围内增加，并已成为一个主要的公共卫生问题。抗药性的演变可能是解释这种复苏的主要因素。在从肯塔基州和俄亥俄州的人类住所收集的种群中，检测到相对于敏感群体对两种拟除虫菊酯类杀虫剂（溴氰菊酯和氯氟氰菊酯）具有极高的抗性水平。抗性群体和敏感群体杂交的后代具有中等敏感性。对来自美国各地种群的评估表明，对拟除虫菊酯类杀虫剂的抗性已经广泛存在。如果不开发新的臭虫管理策略，预计这个公共卫生问题将进一步升级。
