Selection for permethrin and fenvalerate resistance in the red flour beetle Tribolium castaneum Herbst
Issue Date
4-2004
Abstract
A population of red flour beetle originally collected from Vigan, Ilocos Sur received a continuous selection of 8 generations with either permethrin or fernvalerate. The result strains were subjected to toxicity test with and without synergist. The selection resulted in the development of resistance not only to the selecting agents but also to deltamethrin and cypermethrin. The synergist, piperonyl butoxide (PBO) partially suppressed both permethrin and fenvalerate resistance, while S,S,S,-tributyl phosphorotrithioate (DEF) only partially suppressed permethrin resistance. The synergism with themetabolic inhibitors and cross-resistance to Deltamethrin and cypermethrin suggest the presence of multiple mechanism for pyrethroid resistance, i.e. increased degradation and reduced sensitivity at the site of action. High level of resistance to carbaryl and malathion are also exhibited by the pyrethroid-selected strains. Resistance to pirimiphos methyl, fenitrothion and chlorpyrifos methyl was marginal. A combination of pirimiphos methyl, deltamethrin and PBO effectively controlled the susceptible strain for four and a half months storage period. Effect of the combination treatment, however, was not sufficient to control pyrethroid-selected strains.
