目的 :了解乌鲁木齐市德国小蠊对常用杀虫剂的抗药性基数和现状 ,指导科学、合理使用杀虫剂。方法 :微量点滴法。结果 :野外 3个品系德国小蠊对氯氰菊酯、溴氰菊酯、二氯苯醚菊酯和敌敌畏的抗性系数分别为 3 .65～19.69、1.92～ 7.90、0 .78～ 9.3 3、0 .64～ 1.66;对氯氰菊酯产生了较高的抗性。结论 :乌鲁木齐市德国小蠊对
Objective:To direct scientific and rational use of insecticides, the cardinal numbers and status of resistance of Blattella germanica to 4 different insecticides were determined in Urumqi.Methods:The micro-drop method.Results:The resistance indexes of 3 field-collected strains of german cockroaches to cypermethrin, deltamethrin, permethrin and dichlorvos were 3.65-19.69,1.92-7.90,0.78-9.33 and 0.64-1.66, respectively. The resistance to cypermethin reached a high level. Conclusion:Field-collected strains of german cockroaches in Urumqi have already developed various degrees of resistance to these 4 kinds of insecticides in common use.
