Abstract The resistance ratios (RR) of Plutella xylostella in Wuhan were 197.47-and 100.29-folds to fenvalerate and phosemet compared with a susceptible ( S) strain. The RR declined when the Wuhan field strain ( WH) was reared on fresh cabbage leaves in the laboratory.There was no resistance in WH strain after 20 generation because of complete resistance reversion.The susceptibility of both WH and S strain to methomyl was low and the resistance reversion was also slow. The application of this study in insecticide re...
