摘　　要：目的了解上海市长宁区白纹伊蚊成蚊和幼虫对辖区内常用杀虫剂的抗药性情况。方法2023年6月在长宁区5个点位采集野外白纹伊蚊成蚊,在室内饲养1代,选择羽化后3~5 d未吸血雌蚊以及3龄末4龄初幼虫分别进行抗药性测定,成蚊采用接触筒法,幼虫采用浸渍法。结果上海市长宁区白纹伊蚊成蚊对0.2%杀螟硫磷和0.08%高效氯氰菊酯产生抗性,24 h死亡率分别为54.40%和67.20%;对0.05%残杀威和0.07%高效氯氟氰菊酯敏感,24 h死亡率分别为99.22%和98.20%。白纹伊蚊幼虫对吡丙醚、双硫磷产生中抗,吡丙醚的IE 50为0.000394 mg/L,双硫磷的LC_(50)为0.01633 mg/L,对倍硫磷敏感,LC_(50)为0.00308 mg/L。结论上海市长宁区白纹伊蚊对杀螟硫磷、高效氯氰菊酯、吡丙醚,双硫磷均产生不同程度抗药性,对残杀威、高效氯氟氰菊酯、倍硫磷敏感,应在后续减少使用已产生抗药性的药物,选择残杀威、高效氯氟氰菊酯、倍硫磷等敏感药物用于辖区内蚊虫防制。同时应加强蚊虫抗药性的监测,根据抗药性结果科学合理使用杀虫剂,预防与延缓杀虫剂抗性的产生和发展。Objective To investigate the resistance status of Aedes albopictus to commonly used insecticides in Changning District,Shanghai.Methods In June 2023,adult Ae.albopictus were collected from 5 sites in Changning District and their next generation was bred in the laboratory.The non-engorged female adults 3-5 days post eclosion and late third instars and early fourth instars were collected for insecticide resistance testing with the immersion test for larvae and WHO tube test for adults.Results The adults Ae.albopictus were resistance to 0.2%beta-cypermethrin and 0.08%fenitrothion,with 24-hour mortality rates were 54.40%and 67.20%,respectively;sensitive to 0.05%propoxur and 0.07%lambda-cyhalothrin,with 24-hour mortality rates were 99.22%and 98.20%,respectively.The larvae showed moderate resistance to pyriproxyfen and temephos.The IE 50 of pyriproxyfen was 0.000394 mg/L,and the LC_(50)of temephos was 0.01633 mg/L.They were sensitive to fenthion,and its LC_(50)was 0.00308 mg/L.Conclusion Ae.albopictus in Changning District has developed varying degrees of resistance to fenitrothion,beta-cypermethrin,pyriproxyfen and temephos,but is sensitive to propoxur,lambda-cyhalothrin and fenthion.The use of insecticides which resistance has occurred should be reduced.Sensitive insecticides such as propoxur,lambda-cyhalothrin and fenthion can be selected for mosquito control in Changning District.At the same time,the monitoring of mosquito resistance should be strengthened,and insecticides should be used scientifically and rationally based on the results of resistance,so as to prevent and delay the occurrence and development of insecticide resistance.
