title: Insecticide resistance studies on Blattella germanica (Dictyoptera:Blattellidae) from Cuba.
abstract: We studied the levels of resistance to seven insecticides: malathion, chlorpyrifos, pirimiphos-methyl, propoxur, cypermethrin, deltamethrin, and lambda-cyhalothrin in nine strains of Blattella germanica (Linnaeus, 1717) collected from sites in Santiago de Cuba and Havana City. The strains from Santiago de Cuba, generally had high levels of resistance to malathion, cypermethrin, deltamethrin, and lambda-cyhalothrin, but only low levels of resistance to pirimiphos-methyl, chlorpyrifos, and propoxur. In the strains from Havana City we found a moderate resistance to the organophosphate insecticides, resistance to the pyrethroids (except for three strains that showed susceptibility to lambda-cyhalothrin), and susceptibility to the carbamate insecticide (propoxur).
