РЕЗИСТЕНТНОСТЬ ПРИРОДНЫХ ПОПУЛЯЦИЙ MUSCA DOMESTICA L. К СОВРЕМЕННЫМ ИНСЕКТИЦИДАМ

Abstract

To plan and improve the efficiency of disinsection measures at livestock and poultry facilities, the information on the susceptibility of houseflies to modern insecticides is needed. The goal of this study was to determine the susceptibility level to fipronil, acetamiprid, ivermectin, and chlorfenapyr in Musca domestica L. field populations inhabiting agricultural facilities. The study was conducted in one poultry and in two livestock farms. The susceptibility of M. domestica adults of the first generation to insecticides was assessed by the method of dosed contacting, after which the median lethal doses and the resistance ratio were calculated relative to the laboratory culture. According to the results, the fly population from a cattlebreeding farm, in which neonicotinoid fly baits were used for ten years, was highly resistant to acetamiprid (resistance ratio 57) and tolerant to ivermectin (resistance ratio 10). The fly population from poultry farms, in which neonicotinoids were used as baits against flies for four years, was tolerant to acetamiprid (resistance ratio 5). The fly population from a livestock farm, in which insecticides have not been used for more than five years, was susceptible to all insecticides tested. The obtained results and literature data confirmed that the rate of the development of insecticide resistance in field populations of M. domestica depends on the form and duration of the application of insecticide formulations.
