EXPERIENCE OF CONTROLLING ZOOPHILLIC FLIES IN CATTLE FARMS IN THE IVANOVO REGION
Zoophillic flies cause great harm to animal husbandry, which consists of two components: flies carry pathogens of various infectious and invasive diseases on their bodies; microorganisms spread by flies cause damage to livestock products. During the period of flying in large numbers, such damage consists of insufficient milk and a decrease in the daily weight gain of animals. The faunistic collection of zoophillic flies was carried out in calve sheds – prophylactorium houses of cattle farms in the Ivanovo region, Palekhsky district. The comparative efficacy of insecticides with the active substance (AS) thiamethoxam, imidacloprid, and cypermethrin was assessed. The analysis of the data obtained shows that the fauna of zoophillic flies in livestock farms is represented by three families: Calliphoridae (51%), Muscidae (48.2%) and Anthomyiidae (0.8%). The fastest effect of acute insecticidal activity was observed in the drug with the AS imidacloprid, namely, 4 minutes after insects contacting with treated surfaces. In drugs with the AS thiamethoxam and cypermethrin, insecticidal properties appeared after 8 minutes. The longest insecticidal effect was observed in the drug with the AS imidacloprid, it was 13 days, while in drugs with the AS thiamethoxam and cypermethrin, it was just over half of this period.
