Abstract

Objective To understand the resistace status of Blattella germanica to common used insecticides,and provide scientific and reasonable evidence for its control.Methods Using membrane method.Results Blattella germanica was caught on the spot in Luohe and Xinyang city to compare with sensitive strain.The resistance coefficient to beta-cypermethrin,deltamethrin and propoxur was 2.34,2.73;7.48,13.45;1.72,1.84 respectively.The resistnace of Blattella germanica to deltamethrin was on high level in Luohe city.Conclusion Blattella germanica is sensitive to propoxur in Luohe and Xinyang city.It also has a certain degree resistace to beta-cypermethrin and deltamethrin.
