目的：监测河北省城市蜚蠊对５种常用杀虫剂的抗性。方法：采用ＷＨＯ推荐的测定德国小蠊对杀虫剂敏感性的标准方法。结果：德国小蠊对５种常用杀虫剂的ＫＴ５０值范围为１７．７１～５３．２７ｍｉｎ，Ｒ／Ｓ值范围为１．９６～９．９６。结论：本省城市蜚蠊对常用的５种杀虫剂都已程度不同地产生了抗药性，溴氰菊酯对德国小蠊的ＫＴ５０值和Ｒ／Ｓ值最低，残杀威Ｒ／Ｓ值次之，在药物灭蟑工作中可考虑选用。
Objective: To monitor the resistance of cockroaches to five commonly used insecticides in Hebei Province. Methods: The WHO recommended standard method for the determination of Blattella germanica insecticide sensitivity. Results: KT50 values of German cockroach for five commonly used insecticides ranged from 17.71 to 53.27 min with R / S values ranging from 1.96 to 9.96. Conclusion: Cockroaches in urban areas of this province all developed resistance to commonly used five insecticides. Deltamethrin had the lowest KT50 value and R / S value to German cockroach and the lowest R / S value , In the drug cockroach work can be considered selection.
