摘要
目的：了解德国小蠊敏感品系（ｓ）和北京市区４个野外品系（Ｄ、Ｃ１、Ｃ２、Ｈ）对氯氰菊酯、溴氰菊酯、二氯苯醚菊酯及敌敌畏的敏感性，以便通过抗性水平来指导合理用药。方法：药膜接触法。结果：北京市区４个野外品系对上述４种杀虫剂的平均抗性系数分别为敏感品系的３．８１、２．３０、２．９４、３．１６倍；其中二氯苯醚菊酯与敌敌畏在Ｈ品系中、氯氰菊酯在Ｄ品系中均产生了较高抗性，其抗性系数分别为５．３８、６．９７和５．３１。
Objective:To estimate the susceptibility or resistance of german cockroaches,including normal strain and four fieldcollected strains (D,C1,C2,H) to deltamethrin,cypermethrin,permethrin,and dichlorvos.Method:The method of contact with chemical cover was used in this study.Result:The average resistance ratios of fieldcollected strains to deltamethrin,cypermethrin,permethrin and dichlorvos are 3.81,2.30,2.94,3.16 respectively.The resistance ratios of permethrin and dichlorvos are high in Hstrain,(R=5.38,6.97).The resistance also reaches the high level to cypermethrin in Dstrain.(R=5.31).Conclusion:Field collected strains of german cockroaches in Beijing have already developed varied resistance to these four kinds of insecticides.
