摘要:

目的 了解深圳市龙岗区德国小蠊自然种群对5种常用杀虫剂的抗性现状,为指导全区科学合理地使用杀虫剂和提高德国小蠊杀灭效果提供参考。方法 采用粘捕法捕捉蜚蠊,分类鉴定后通过广口瓶药膜接触法检测德国小蠊对常用杀虫剂的抗性水平。结果 共捕获蜚蠊1026只,其中德国小蠊占97.95%,为优势种;龙岗区德国小蠊自然种群对高效氯氰菊酯、溴氰菊酯、双硫磷、残杀威和仲丁威均产生了不同程度的抗性,抗性系数依次为25.27、10.65、12.73、4.55和14.59,其中高效氯氰菊酯抗性最为突出(抗性系数>20)。结论 深圳市龙岗区德国小蠊对高效氯氰菊酯、溴氰菊酯、双硫磷和仲丁威已产生高抗性。

Abstract:

Objective To investigate the resistance of Blattella germanica to five kinds of insecticides in Longgang district of Shenzhen for providing scientific data for its effective control. Methods Insecticide membrane method was used to capture the insects, which were identified classified and tested for their insecticide resistance level with drug-membrane contact method. Results A total of 1026 cockroaches, of which the dominant species B. germanica accounting for 97.95%, were captured. The results indicated that the field-collected strain of B. germanica was resistant to all the 5 kinds of insecticides, with the resistance coefficient of it to beta-cypermethrin, deltamethrin, biothion, propoxur and fenobucarb being 25.27, 10.65, 12.73, 4.55 and 14.59, respectively, showing that the resistance to beta-cypermethrin was most significant (R>20). Conclusion B. germanica in Longgang district of Shenzhen has high resistance to beta-cypermethrin, deltamethrin, biothion, and fenobucarb.
