摘要
目的测定张家港市淡色库蚊对溴氰菊酯、高效氯氰菊酯、氯菊酯、双硫磷、仲丁威等5种常用杀虫剂的抗性。方法在张家港市郊区采集淡色库蚊幼虫,采用WHO生物测试法进行测定。结果 2016年张家港市淡色库蚊对上述5种杀虫剂的抗性倍数分别为6.54、6.17、2.13、65.15、8.25。张家港市淡色库蚊对双硫磷已产生高度抗药性,对溴氰菊酯、高效氯氰菊酯、氯菊酯、仲丁威也已产生不同程度的抗药性,但抗性水平较低。结论应该根据不同杀虫剂的抗性合理选择用药,加强淡色库蚊的抗药性监测,预防或延缓抗药性产生。
Objective To detect the resistance of Culex pipiens pallens to five commonly used insecticides including deltamethrin,beta-cypermethrin,permethrin,biothion and fenobucarb. Methods Larvae of Cx. pipiens pallens were collected in the suburbs of Zhangjiagang City,and tested with WHO standard bioassay to calculate LC50. Results Culex pipiens pallens developed 6. 54,6. 17,2. 13,65. 15 and 8. 25 folds resistance respectively to deltamethrin,betacypermethrin,permethrin,biothion and fenobucarb. Conclusion It is necessary to apply insecticides rationally and scientifically. Resistance surveillance should be strengthened to delay the development of mosquito resistance.
