【Abstract】 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.更多还原
