摘要:

目的 了解江苏省部分地区淡色库蚊幼虫对常用杀虫剂的抗性状况,指导对蚊幼虫防治药物的合理使用。方法 选择7种常用化学杀虫剂,采用幼虫浸渍法对江苏省南京、南通、淮安地区的淡色库蚊幼虫进行抗药性测定。结果 与实验室敏感品系比较,南京、南通、淮安地区的淡色库蚊幼虫对敌敌畏抗药性均为最高,南通和淮安种群对氯菊酯的抗药性最低,南京种群对生物丙烯菊酯抗药性最低,对氯菊酯的抗药性与对生物丙烯菊酯的接近。结论 在对蚊幼虫防治时,杀虫剂的选择应考虑当地抗药性情况,并合理控制使用,减少使用抗性较高的敌敌畏、残杀威和双硫磷,选用抗药性较低的拟除虫菊酯类杀虫剂。

Abstract:

Objective To determine the resistance of Culex pipiens pallens larvae to commonly used insecticides in parts of Jiangsu province, providing the guidance on proper administration of mosquito control agents. Methods Using 7 common chemical pesticides, the resistance of Cx. pipiens pallens larvae in Nanjing, Nantong and Huaian regions of Jiangsu province was measured by larval impregnation. Results Compared with the laboratory susceptible strain, the Cx. pipiens pallens larvae from Nanjing, Nantong and Huaian each had the highest resistance to dichlorvos, while the populations from Nantong and Huaian had the lowest resistance to permethrin. The Nanjing population had the lowest resistance to bioallethrin, and similar resistance to permethrin. Conclusion Suitable insecticides should be used for prevention and control of mosquito larvae, taking into account the regional resistance. To properly apply insecticides, dichlorvos, propoxur, and temephos which mosquitoes are highly resistant to should be gradually replaced by pyrethroids.
