目的 了解浙江省白纹伊蚊成蚊对5种常用卫生杀虫剂的抗性现状，为防控白纹伊蚊提供科学依据。方法 2016年4-6月采集浙江省12个市的野外白纹伊蚊幼虫，在实验室饲养至成蚊，采用WHO推荐的接触筒法测定其抗药性。结果 将白纹伊蚊成蚊暴露于3%高效氯氰菊酯、0.1%溴氰菊酯、3%氯菊酯、0.44%马拉硫磷和0.06%残杀威各1 h，24 h死亡率分别为89.33%~100%、97.78%~100%、97.78%~100%、50.67%~100%和90.67%~100%。结论 浙江省白纹伊蚊成蚊对马拉硫磷已经产生抗药性，对高效氯氰菊酯和残杀威的抗性还需进一步确定。应加强白纹伊蚊的抗药性监测，科学合理使用杀虫剂，以预防或延缓抗药性的产生。
Objective To investigate the resistance status of adults Aedes albopictus to five commonly used insecticides in Zhejiang province, providing guidance to the control of Ae. albopictus. Methods Larval mosquitoes were collected in 12 cities of Zhejiang province, and were reared to adults in the insectary, then tested using WHO standard test kits from April to June, 2016. Results Adult mosquitoes exposed to 3% beta-cypermethrin, 0.1% deltamethrin, 3% permethrin, 0.44% malathion and 0.06% propoxur for 1 h, the mortality 24 h later were 89.33%-100%, 97.78%-100%, 97.78%-100%, 50.67%-100%, and 90.67%-100%. Conclusion Aedes albopictus showed resistance to malathion, and further researches are needed to confirm the resistance to propoxur, beta-cypermethrin. In practice, insecticides resistance surveillance should be highlighted and insecticides should be used strategically to prevent and reduce the development of resistance.
