Abstract

Mosquito-borne pathogens are a threat to US troops stationed in the Republic of Korea. From April 2023 until December 2024, larvae and pupae of Aedes albopictus, Ae. koreicus, and Culex pipiens collected from U.S. Army garrisons were screened for resistance to chlorpyrifos, deltamethrin, etofenprox and permethrin using the Centers for Disease Control and Prevention bottle bioassay. Colonies of Cx. pipens var. molestus from Camp Humphreys, Camp George, and the Busan Storage Facility were established and tested against permethrin and permethrin + piperonyl butoxide (PBO). No resistance to deltamethrin or chlorpyrifos was detected in Ae. albopictus populations, but 1 population from Camp George showed possible resistance to permethrin. Aedes koreicus indicated possible resistance to etofenprox from Camp Casey in 2023 and resistance to etofenprox from Camp Casey in 2024. All populations of Ae. koreicus tested were susceptible to chlorpyifos, permethrin, and deltamethrin. Culex pipiens field-collected populations were susceptible to chlorpyrifos and resistant to permethrin, etofenprox, and deltamethrin. Exposing laboratory Cx. pipiens var. molestus to PBO and then permethrin restored susceptibility to all 3 colonies. Screening will be ongoing to track changes in resistance status for these species.

美国疾病控制与预防中心（CDC）对驻韩美军驻地白纹伊蚊、朝鲜伊蚊和淡纹库蚊（2023年和2024年）杀虫剂抗性检测的瓶子生物测定法。

蚊媒病原体对驻韩美军构成威胁。从2023年4月至2024年12月，白纹伊蚊的幼虫和蛹，伊蚊。采用美国疾病控制和预防中心的瓶子生物测定法，对美国陆军驻地的库蚊和库蚊进行了毒死蜱、溴氰菊酯、乙醚菊酯和氯菊酯的抗性筛选。Cx的殖民地对来自汉弗莱营、乔治营和釜山储运设施的斑蝽进行了对氯菊酯和氯菊酯+吡啶酰丁醇（PBO）的抗性试验。对溴氰菊酯和毒死蜱均无抗性。除乔治营1只白纹伊蚊对氯菊酯可能产生抗性外。伊蚊在2023年和2024年分别对凯西营的乙托苯丙酯和凯西营的乙托苯丙酯产生抗药性。所有种群的伊蚊。对毒死蜱、氯菊酯和溴氰菊酯敏感。现场采集的库蚊种群对毒死蜱敏感，对氯菊酯、乙醚菊酯和溴氰菊酯耐药。暴露实验室Cx。用氯菊酯处理后，小纹库蚊对PBO的敏感性均有所恢复。将继续进行筛选，以跟踪这些物种耐药性状况的变化。

期刊介绍： The Journal of the American Mosquito Control Association (JAMCA) encourages the submission of previously unpublished manuscripts contributing to the advancement of knowledge of mosquitoes and other arthropod vectors. The Journal encourages submission of a wide range of scientific studies that include all aspects of biology, ecology, systematics, and integrated pest management. Manuscripts exceeding normal length (e. g., monographs) may be accepted for publication as a supplement to the regular issue.
