摘　　要：目的了解白纹伊蚊成蚊对常用杀虫剂的抗药性,为科学选择和使用杀虫剂提供依据。方法2018年9月在厦门市思明、集美、海沧区和2019年8月在厦门市思明、集美、翔安区,采用勺舀法采集野外白纹伊蚊幼虫和卵块,在实验室饲养至成蚊。采用接触筒法测定白纹伊蚊成蚊对7种常用杀虫剂的抗药性,计算1 h击倒率和恢复24 h死亡率。根据死亡率判断抗药性水平:≥98%为敏感群体(S);80%~<98%为可能抗性群体(M);<80%为抗性群体(R)。结果2018和2019年白纹伊蚊成蚊暴露于0.1%溴氰菊酯、0.4%高效氯氰菊酯、0.5%高效氯氟氰菊酯、1.4%顺式氯氰菊酯、3%氯菊酯、0.5%马拉硫磷、0.05%残杀威7种常用杀虫剂,1 h击倒率分别为95.1%(117/123)、98.3%(115/117)、100.0%(116/116)、99.2%(120/121)、98.4%(123/125)、97.5%(119/122)、100.0%(127/127)和96.7%(118/122)、98.6%(143/145)、100.0%(139/139)、100.0%(149/149)、98.0%(146/149)、96.8%(121/125)、100.0%(126/126)。2018年恢复24 h死亡率分别为91.1%(112/123)、78.6%(92/117)、75.0%(87/116)、88.4%(107/121)、96.0%(120/125)、99.2%(121/122)、100.0%(127/127),2019年恢复24 h校正死亡率分别为74.9%、76.9%、79.5%、91.4%、92.3%、100.0%、100.0%。结论厦门市白纹伊蚊成蚊对马拉硫磷和残杀威敏感,对溴氰菊酯、高效氯氰菊酯和高效氯氟氰菊酯等拟除虫菊酯类杀虫剂抗药性高。要加强抗药性监测,交替使用不同类型杀虫剂,以减少和延缓抗药性的产生。Objective To investigate the resistance of adult Aedes albopictus to commonly used insecticides,in order to scientifically select and use insecticides.Methods In Siming,Jimei and Haicang districts of Xiamen City in September 2018,and in Siming,Jimei and Xiang'an districts of Xiamen City in August 2019,larvae and egg blocks of Aedes albopictus in the field were collected by ladle method,and then raised to adult mosquitoes in the laboratory.The resistance of adult Aedes albopictus to 7 commonly used insecticides was determined by the contact tube method,and the knockdown rate of 1 h and mortality rate of 24 h recovery were calculated.The resistance level was determined according to the mortality rate:≥98%was the sensitive group(S);80%-<98%was potential resistant group(M);<80%was resistant group(R).Results In 2018 and 2019,adult Aedes albopictus were exposed to 0.1%deltamethrin,0.4%beta-cypermethrin,0.5%lambda-cyhalothrin,1.4%alpha-cypermethrin,3%permethrin,0.5%malathion and 0.05%propoxur,the knockdown rates of 1 h were 95.1%(117/123),98.3%(115/117),100.0%(116/116),99.2%(120/121),98.4%(123/125),97.5%(119/122),100.0%(127/127)and 96.7%(118/122),98.6%(143/145),100.0%(139/139),100.0%(149/149),98.0%(146/149),96.8%(121/125),and 100.0%(126/126),respectively.In 2018,the mortality rates of 24 h recovery were 91.1%(112/123),78.6%(92/117),75.0%(87/116),88.4%(107/121),96.0%(120/125),99.2%(121/122),and 100.0%(127/127),respectively.In 2019,the adjusted mortality rates of 24 h recovery were 74.9%,76.9%,79.5%,91.4%,92.3%,100.0%,and 100.0%,respectively.Conclusions Adult Aedes albopictus in Xiamen City is sensitive to malathion and propoxur,and it has a high resistance to pyrethroids insecticides such as deltamethrin,beta-cypermethrin and lambda-cyhalothrin.Therefore,it is necessary to strengthen resistance monitoring and use different insecticides in turn to reduce and delay the development of resistance.
