The development of resistance in the housefly (Musca domestica) to azamethiphos, pirimiphosmethyl, bendiocarb, permethrin, cypermethrin, and deltamethrin was investigated on pig farms over a 4-year period. The results obtained in laboratory tests were compared with those obtained under practival conditions in piggeries. An intensive use of insecticides induced resistance in the course of 2 to 3 seasons. The classic spray regimes of insecticides led to the development of high resistance after one or two seasons. Integrated control, based on rotational applicaton - organophosphate, pyrethroid, carbamate, pyrethroid, organophosphate - retained the resistance at low to moderate levels. The rotational application of azamethiphos and permethrin or cypermethrin having sufficient insecticidal effect retained the resistance at low to moderate levels over a 4-year period. Although the alteration of insecticides cannot prevent the development of resistance, it can extend several times the period of their successful application on farms.
