Abstract: Objective To determine the resistance status of Aedes albopictus to commonly used insecticides in Wuhan, China, 2019-2021, and to provide a basis for formulating scientific and reasonable prevention and control measures. Methods Insecticide susceptibility tube test was used to examine the mortality of Ae. albopictus adultsto six insecticides at the diagnostic dose, and larva dipping test was used to examine the toxicity of nine insecticides to Ae. albopictus larvae. SPSS 20.0 software was used for probability regression analysis to calculate the median lethal concentration or half maximal inhibitory concentration of the insecticide to Ae. albopictus larvae. Results Ae. albopictus adults developed varying degrees of resistance to deltamethrin, permethrin, beta-cypermethrin, and lambda-cyhalothrin, with mortality rates ranging from 5.88% to 68.75%, and showed sensitivity to propoxur and malathion, with mortality rates of 100%. Ae. albopictus larvae demonstrated different degrees of resistance to deltamethrin, beta-cypermethrin, propoxur, Bacillus thuringiensis, and pyriproxyfen, with resistance ratios ranging from 4.40 to 76.20, and showed sensitivity to malathion and temephos, with resistance ratios of 0.30 and 2.38, respectively. Conclusion Ae. albopictus in Wuhan develops varying levels of resistance to different types of insecticides, including pyrethroids, carbamates, biological insecticides, and insect growth regulators. Surveillance and management of resistance of Ae. albopictus should be strengthened to further improve to formulate scientific, reasonable, and comprehensive prevention and control measures.

摘要: 目的 了解2019-2021年武汉市白纹伊蚊对常用卫生杀虫剂的抗药性水平,为制定科学、合理的防制措施提供依据。方法 采用成蚊接触筒法检测白纹伊蚊在6种杀虫剂诊断剂量下的死亡率;采用幼虫浸渍法检测9种杀虫剂对白纹伊蚊幼蚊的毒性,并使用SPSS 20.0软件进行概率回归分析,计算杀虫剂对白纹伊蚊幼蚊的半数致死浓度或半数抑制剂量。结果 白纹伊蚊成蚊对溴氰菊酯、氯菊酯、高效氯氰菊酯和高效氯氟氰菊酯均产生不同程度的抗性,死亡率在5.88%~68.75%;对残杀威和马拉硫磷表现为敏感,死亡率均为100%。白纹伊蚊幼蚊对溴氰菊酯、高效氯氰菊酯、残杀威、苏云金芽孢杆菌及吡丙醚均产生不同程度抗性,抗性倍数为4.40~76.20倍;对马拉硫磷和双硫磷为敏感,抗性倍数分别为0.30和2.38倍。结论 武汉市白纹伊蚊对拟除虫菊酯类、氨基甲酸酯类、生物杀虫剂以及昆虫生长调节剂等类型杀虫剂均产生了不同程度抗药性。建议加强白纹伊蚊抗药性的监测和治理,进一步完善并形成科学、合理的综合防制措施。
