近年来，臭虫在全球范围内经历了惊人的复苏。虽然报道主要集中在常见的臭虫，温带臭虫，在热带地区，半翅臭虫Cimex hemipterus（F.）（半翅目：Cimicidae），也重新出现。最近的报道C.在该物种自然分布区之外，将半翅目引入亚热带和温带地区，表明有可能建立和进一步传播。杀虫剂抗性机制可能有助于建立，例如存在敲低抗性（kdr）相关突变，这可能赋予拟除虫菊酯、除虫菊酯和有机氯杀虫剂抗性。在这里，我们提出的检测和可能建立的C。夏威夷檀香山的半翅目，来自2009年和2019年收集的样本。此外，通过对电压门控钠通道的部分测序，我们报告了所有样本中kdr相关突变的存在。这些研究结果的实施，旨在消除虫害的控制策略的影响。
In recent years, bed bugs have experienced a remarkable resurgence on a near global scale. While reports have primarily focused on the common bed bug, Cimex lectularius (L.), which has resurged largely in temperate regions, in tropical regions the tropical bed bug, Cimex hemipterus (F.) (Hemiptera: Cimicidae), has reemerged as well. Recent reports of C. hemipterus introductions to subtropical and temperate regions, outside of the species natural distribution, suggest the potential for establishment and further spread. Establishment may be aided by insecticide resistance mechanisms, such as the presence of knockdown resistance (kdr)-associated mutations, which potentially confer resistance to pyrethroid, pyrethrin, and organochloride insecticides. Here, we present the first report of the detection and likely establishment of C. hemipterus in Honolulu, Hawaii, from samples collected in 2009 and 2019. Furthermore, through partial sequencing of the voltage-gated sodium channel, we report the presence of kdr-associated mutations in all samples. These findings have implications for the implementation of control strategies aimed at eradicating infestations.
