Insecticidal efficacy of the drug «Phytocreolin», which affects the number of zoophilic flies

This article examines the insectoacaricidal effectiveness of the drug «Phytocreolin» on the number of zoophilic flies in open and closed livestock premises. For the first time, the authors conducted studies of the insectoacaricidal efficacy of the drug «Phytocreolin» based on pine tar, how it differs from creolin, and having a repellent effect against insects and, thereby, contributing to a decrease in the number of zoophilic flies in livestock premises. Studies conducted to establish the background number of imago flies in open and closed types, followed by an entomological assessment of zoophilic flies, showed that the dominant biological species was the gray meat fly (Sarcophaga bullata), which accounted for about 80% of the total number of flies. Such a large number of this species is due to the active summer season, as well as the time of research. The housefly (Musca domestica) was also found in the insects, the number of which amounted to 10% of the total number of zoophilic flies. In addition, the autumn stable fly (Stomoxys calcitrans), which accounted for about 7%, and the common green carrion (Lucilia caeza), 3% of the total number of zoophilic flies, were also found in livestock facilities. It was found that the effectiveness of the insecticide drug in the disinfection of livestock premises of a closed type for the entire period of experience, when disinfecting with a 25% solution of the drug in reducing the number of insects was 15,3%, when treated with a 50% solution, the effectiveness was the best and amounted to 29,8% and when disinfecting with a 100% solution, the decrease in the number of zoophilic flies was about 21,7%. Similar results of the effectiveness of the use of an insecticidal drug were obtained in open-type livestock facilities. So, over the entire period of the experiment, when disinfecting with a 25% solution of the drug, the decrease in the number of insects was 9,6%, when treated with a 50% solution – 23% and when disinfecting with a 100% solution, the insecticidal efficiency was the best and amounted to 26%.
