摘要:

  【摘要】 目的 应用一种家蝇抗药性早期检测方法即乙酰胆碱酯酶(AChE)法,了解南昌市不同生境家蝇对常用的有机磷和氨基甲酸酯类杀虫剂的抗性现状及其发展趋势。方法 采用微量点滴法进行生物测定,同时采用AChE检测不同生境家蝇对敌敌畏和残杀威的抗性水平。结果 生物测定结果表明,居民区、餐饮店、垃圾中转站和农贸市场4个家蝇品系对敌敌畏和残杀威产生了不同程度的抗性,对敌敌畏的抗性指数依次为34.07、22.57、20.05、17.43倍,其中农贸市场品系为中抗水平,其余3个品系均达高抗水平;对残杀威的抗性仍处于低抗水平,抗性指数依次为2.68、3.48、2.15、2.74倍。AChE法的检测结果表明,居民区、餐饮店、垃圾中转站和农贸市场品系对敌敌畏的抗性个体频率依次为100%、82%、55%和29%,均为敌敌畏抗性品系;对残杀威抗性个体频率依次为28%、42%、12%、27%,其中垃圾中转站品系抗性个体频率<20%,其他3个品系均为残杀威抗性品系。结论 AChE法检测结果与生物测定结果基本相符,该法可以应用于野外家蝇抗性的早期检测。南昌市不同生境家蝇对敌敌畏达中抗或高抗水平,建议停用;对残杀威也产生了一定程度的抗性,且有发展的趋势,应换用或轮用其他杀虫剂,以避免或延缓抗性的发展。

Abstract:

  【Abstract】 Objective To detect the resistance of Musca domestica in various habitats in early phase with the method of acetylcholinesterase. Methods The  traditional  assay  method  and  acetylcholinesterase  were  used  to  detect  the  resistance  of M. domestica  in  various  habitats  to  dichlorvos (DDVP)  and  propoxur. Results The  bioassay results showed that 4 strains of M. domestica in the residential areas, restaurants, refuse transfer stations and agricultural fair had different resistance to DDVP, and the resistance ratio were 34.07, 22.57,20.05 and 17.43, respectively. The resistance ratio to propoxur was 2.68, 3.48, 2.15 and 2.74, respectively. The DDVP-resistance individual rates of 4 strains in the residential areas, restaurants, refuse transfer stations and agricultural fair were 100%, 82%, 55% and 29%, while propoxur-resistant individual rates of them were 28%, 42%, 12% and 27%, respectively. Except for the strain in refuse transfer stations, the others had resistance to DDVP and propoxur. Conclusion The detection results of acetylcholinesterase were basically consistent with that of bioassays, and it could be used to the early detection of resistance. The 4 resistant strains had middle or high resistance to DDVP and low resistance to propoxur. So, DDVP should be inhibited, and the mixed and rotational use measure could be taken to avoid and delay the development of resistance.
