Abstract:

Objective To investigate the susceptibility of Armigeres subalbatus to commonly used pesticides in Suqian city, Jiangsu province. Methods Dipping method was used to detect LC50 of Suqian field population of Ar. subalbatus to abate, fenobucarb, deltamethrin, betacypermethrin and permethrin. Results The LC50(mg/L)of Suqian population of Ar. subalbatus to abate, fenobucarb, deltamethrin, betacypermethrin and permethrin was 0.059 36, 2.563 5, 0.000 457 2, 0.000 443 2 and 0.001 701 respectively, was 7.24, 2.68, 0.21, 0.09, and 0.11 times of LC50 of Suqian population of Cluex pipiens pallens collected from same site on same pesticides. Conclusion Compared with Suqian population of Cx. pipiens pallens, Ar. subalbatus was more resistant to organophosphorus and carbamate pesticides, more susceptible to pyrethroids. IPM was recommended in the control of Ar. subalbatus. Controlling larvae by eliminating of dirty water of vessels and ditches, using pyrethroids or B.t.i. or B. sphaericus biopesticide, were better than controlling adults of Ar. subalbatus, but chemical control on adults of Ar. subalbatus would be the first selection at high vector density or during epidemic period of vector diseases.

摘要:

目的 了解江苏省宿迁市骚扰阿蚊对常用杀虫剂的敏感性现状。方法 采用浸渍法测定骚扰阿蚊宿迁种群对双硫磷、仲丁威、溴氰菊酯、高效氯氰菊酯和氯菊酯的半数致死浓度(LC50),了解其敏感性情况。结果 骚扰阿蚊宿迁种群对双硫磷、仲丁威、溴氰菊酯、高效氯氰菊酯和氯菊酯的LC50 分别为0.059 36、2.563 5、0.000 457 2、0.000 443 2和0.001 701 mg/L,是淡色库蚊敏感品系对相同杀虫剂LC50的148.40、10.13、0.35、0.12和0.06倍,是同一采集地淡色库蚊宿迁种群对相同杀虫剂LC50的7.24、2.68、0.21、0.09和0.11倍。结论 骚扰阿蚊宿迁种群对有机磷类和氨基甲酸酯类的耐药性程度要高过同一生境同时采集的淡色库蚊宿迁种群,但对拟除虫菊酯类较淡色库蚊宿迁种群更为敏感;宿迁市骚扰阿蚊的防治应采取以环境治理为主,化学防治为辅的综合治理措施;非密度高发期、非蚊媒传染病暴发等重大事件发生期,强调蚊幼虫的防治重于成蚊的防治,且蚊幼虫防治首选拟除虫菊酯类化学杀虫剂或苏云金杆菌(Bt.)、球形芽孢杆菌(Bs.)等生物杀虫剂;当骚扰阿蚊成蚊高密度或蚊媒传染病暴发等重大事件发生时,应加强成蚊的化学防治,同时做到科学合理用药。
