摘要: 目的 了解重庆市德国小蠊对常用卫生杀虫剂的抗药性状况,为该地区合理用药提供依据。方法 2015-2016年采用药膜接触法对重庆市10个区的德国小蠊进行抗药性测定,计算各药剂对德国小蠊的半数击倒时间和抗性倍数。结果 重庆市10个区德国小蠊对高效氯氰菊酯、溴氰菊酯、氯氰菊酯、乙酰甲胺磷、DDVP、毒死蜱和残杀威的抗性倍数分别为13.76~32.93、5.26~15.25、4.81~21.02、1.01~2.11、1.05~7.38、1.00~1.20和1.02~2.12倍。乙酰甲胺磷和毒死蜱对重庆市不同地区德国小蠊野外种群的72 h平均死亡率均为100%;DDVP、溴氰菊酯、氯氰菊酯、残杀威和高效氯氰菊酯对德国小蠊的72 h平均死亡率分别为94.0%、92.0%、81.0%、79.0%和78.0%。结论 重庆市德国小蠊对7种卫生杀虫剂产生了不同程度的抗药性。建议合理选用杀虫剂,以延缓德国小蠊抗药性发展。

Abstract: Objective To investigate the susceptibility of Blattella germanica to commonly used insecticides and optimize future application of insecticides. Methods The surface contact method was used, calculating the medium knock-down time(KT50) and obtaining resistance ratios by comparing with susceptible strain from 2015 to 2016. Results The resistance index of field-collected strains of B. germanica to beta-cypermethrin, deltamethrin, cypermethrin, acephate, DDVP, ehlorpyrifos, and propoxur were 13.76-32.93, 5.26-15.25, 4.81-21.02, 1.01-2.11, 1.05-7.38, 1.00-1.20, and 1.02-2.12. The average mortality of B. germanica in different areas of Chongqing after 72 h of contacting to acephate, ehlorpyrifos, DDVP, deltamethrin, cypermethrin, propoxur, and beta-cypermethrin were 100%, 100%, 94.0%, 92.0%, 81.0%, 79.0% and 78.0%. Conclusion Field collected strains of B. germanica in Chongqing have already developed different resistance to seven kinds of insecticides. Insecticides should be applied strategically to manage the insecticide resistance of B. germanica effectively.
