摘　　要：目的了解南昌市野生种群德国小蠊2006-2016年10年间对常用杀虫剂的抗性发展趋势。方法分别于2006、2010、2014、2016年的6-7月在南昌市的农贸市场、餐饮店、宾馆及超市采集野生种群的德国小蠊带回实验室饲养,采用WHO推荐的药膜法及诊断剂量法(GB/T 26352-2010《蜚蠊抗药性检测方法德国小蠊生物测定法》)进行抗药性测试。结果 2006-2016年经药膜法检测,南昌市野生种群德国小蠊2010、2016年对DDVP的抗性系数分别为1.44和1.45倍,2014、2016年对乙酰甲胺磷分别为0.53和0.77倍,2006、2010、2014、2016年对残杀威分别为1.09、1.36、1.25和1.74倍,2006、2010、2016年对溴氰菊酯分别为1.36、12.73和16.01倍,2006、2010、2014、2016年对高效氯氰菊酯分别为4.99、3.57、4.72和10.04倍,2014、2016年对氯氟氰菊酯分别为2.34和5.39倍,2014、2016年对顺式氯氰菊酯分别为3.19和5.99倍。用诊断剂量法检测南昌市野生种群德国小蠊对DDVP、残杀威的抗药性,显示均已产生抗性。结论 2006-2016年南昌市野生种群德国小蠊对溴氰菊酯等拟除虫菊酯类杀虫剂抗性由低抗发展到中抗,部分达高抗水平,对DDVP、残杀威保持低抗水平,对乙酰甲胺磷较敏感。Objective To investigate the resistance dynamics for Nanchang field strain of Blattella germanica against the commonly used insecticides from 2006 to 2016.Methods Field B.germanica strains were collected from the farm product markets,restaurants,hotels and supermarkets on June and July in 2006,2010,2014,and 2016.Residual film method and diagnostic dose method were used.Results From 2006 to 2016,by examining with the residual film method,we found that the resistance ratios of the Nanchang field strain of B.germanica against each insecticide were as follows：DDVP,1.44,1.45; acephate,0.53,0.77; propoxur,1.09,1.36,1.25,1.74; deltamethrin,1.36,12.73,16.01; beta-cypermethrin,4.99,3.57,4.72,10.04;cyhalothrin,2.34,5.39,and alpha-cypermethrin,3.19,5.99.By diagnostic dose method,the resistance of Nanchang field strain of B.germanica against DDVP and propoxur has also been found.Conclusion From 2006 to 2016,the resistance to pyrethroid insecticides such as deltamethrin has developed from low to medium level,part of them reached high level.The resistance to DDVP,chlorpyrifos and propoxur remained low.The Nanchang strain of B.germanica remains susceptible to acephate.
