摘　　要：目的掌握云南省瑞丽市埃及伊蚊和白纹伊蚊对常用杀虫剂的抗药性水平,为登革热媒介伊蚊综合治理提供依据。方法于2016年6-9月分别从云南省瑞丽市城区和姐告口岸采集埃及伊蚊和白纹伊蚊蛹或幼虫,实验室繁殖至子一代(F1),采用成蚊滤纸接触筒法,测定其对常用杀虫剂的抗药性,判定其抗性程度。结果瑞丽市城区埃及伊蚊对0.25%氯菊酯、0.03%氯氟氰菊酯、8.00%顺式氯氰菊酯、0.80%马拉硫磷、0.25%杀螟硫磷、0.10%残杀威和4.00%DDT的24 h后校正死亡率分别为1.40%(抗性)、20.12%(抗性)、80.31%(可疑抗性)、100%(敏感)、100%(敏感)、100%(敏感)和14.93%(抗性);姐告口岸埃及伊蚊对上述杀虫剂24 h后校正死亡率分别为0.55%(抗性)、2.13%(抗性)、62.35%(抗性)、100%(敏感)、100%(敏感)、100%(敏感)和0(抗性)。另外,瑞丽市城区白纹伊蚊对0.75%氯菊酯、1.80%氯氟氰菊酯、8.00%顺式氯氰菊酯、0.10%溴氰菊酯、3.00%高效氯氰菊酯、0.44%马拉硫磷、0.18%杀螟硫磷和0.06%残杀威的24 h后校正死亡率分别为8.11%(抗性)、83.85%(可疑抗性)、75.18%(抗性)、4.97%(抗性)、89.13%(可疑抗性)、99.23%(敏感)、100%(敏感)和100%(敏感)。结论瑞丽市埃及伊蚊和白纹伊蚊对拟除虫菊酯类杀虫剂均产生了不同程度的抗药性;对有机磷类和氨基甲酸酯类杀虫剂仍敏感。Objective To investigate the resistance of Aedes aegypti and Ae. albopictus to insecticides in Ruili city, Yunnanprovince, to provide the basis for integrated control of dengue vector. Methods Larvae of Ae. aegypti and Ae. albopictus were collected in Ruili city and Jiegao port and reared in laboratory to get F1 generation, to test their susceptibility todifferent kinds of insecticides by bioassays. The resistance level was decided by adjusted mortality. Results The 24 hmortality rate of adult Ae. aegypti in Ruili city to 0.25% permethrin, 0.03% λ-cyhalothrin, 8.00% α-cypermethrin,0.80%malathion, 0.25% fenitrothion, 0.10% propoxur, and 4.00% DDT were 1.40%（resistant）, 20.12%（resistant）, 80.31%（suspicious resistant）, 100%（susceptible）,100%（susceptible）, 100%（susceptible） and 14.93%（resistant）respectively. The24 h mortality rate of adult Ae. aegypti in Jiegao port to above insecticides were 0.55%（resistant）, 2.13%（resistant）,62.35%（resistant）, 100%（susceptible）, 100%（susceptible）, 100%（susceptible） and 0（resistant） respectively. In addition,the 24 h mortality of adult Ae. albopictus in Ruili city to 0.75% permethrin, 1.80% λ-cyhalothrin, 8.00% α-cypermethrin,0.10% deltamethrin, 3.00% beta-cypermethrin, 0.44% malathion, 0.18% fenitrothion and 0.06% propoxur were 8.11%（resistant）, 83.85%（suspicious resistant）, 75.18%（resistant）, 4.97%（resistant）, 89.13%（suspicious resistant）, 99.23%（susceptible）, 100%（susceptible） and 100%（susceptible） respectively. Conclusion Aedes aegypti and Ae. albopictus inRuili city have developed different levels resistance to pyrethroid insecticides, but present high susceptible to malathion,fenitrothion and propoxur.
