Insecticide susceptibility of house flies (Musca domestica) from a livestock farm in Tyumen region, Russia

The susceptibility of the field populations of the house fly Musca domestica L. (Diptera:Muscidae) from a livestock farm of the Tyumen region, Russia, to six insecticides (deltamethrin, cypermethrin, thiamethoxam, permethrin, fipronil, chlorfenapyr) is reported. After a forced contact of adult flies of susceptible strains and first generation of field populations with the residues of insecticides at the bottom of glass cups, the median lethal dose of each insecticide was determined by probit analysis. According to the resistance ratio, the susceptibility of the evaluated field population to insecticides increased in the order: cypermethrin < deltamethrin < permethrin ≤ chlorfenapyr < thiamethoxam < fipronil
