The evaluation of the effectiveness of fipronil and chlorfenapyr against Musca domestica L. on the objects of veterinary supervision

The aim of the study was to evaluate the effectiveness of the mixture of insecticides fipronil, chlorphenapir and separately as a part of decoy agents against houseflies Musca domestica in production conditions. As a binary bait, the developed Mukhnet FX products with the content of active substances fipronil 0.0015 % and chlorphenapir 0.06 %, and monocomponent preparations MukhentF (fipronil 0.15 %), Mukhent X (chlorphenapir 6 %) were tested. The Russian Federation patents RU 2711383 for a mixture of insecticides and RU 2646044 separately were obtained for the methods of using these agents. The research was conducted in livestock and poultry facilities of agro-industrial enterprises in Tyumen Region. The number of the flies was recorded before and after treatment with insecticide baits until they were completely restored using sticky sheets (10×50 cm). During the observation period, the number of flies in the premises ranged from 3.2 to 38 thousand per m2 of the registration sheet. The preparations were diluted with water in a ratio of 1:3 and then applied to substrates (20×60 cm) at the rate of 250 ml per 1 m2 of surface, and fly clusters were treated in the amount of 5 pieces per 100 m2. On the first day after processing it was revealed that all the preparations showed more than 90 % efficiency. The number of flies almost returned to the initial level after treatment with Mukhnet X and Mukhnet F on the eighth day, and after applying Mukhnet FH only up to 30 %, a complete recovery occurred on the 14-th day of observations.
