Abstract
<jats:p>This article presents the results of a comprehensive study of the effectiveness of pest control measures in livestock buildings using various types of spraying equipment. Experimental work was conducted at the Abdibekov farm in the Kostanay region from May to October 2025. Entomological monitoring identified eight species of zoophilic flies belonging to three genera and families: Muscidae, Calliphoridae, and Sarcophagidae. Representatives of the Muscidae family were dominant, with a dominance index of 60.2%. Peak insect numbers were observed in the second ten days of July, after which a gradual decline was noted. For pest control, the insecticides "Cyperil 10%" and "Delcid" were used, using "Zhuk" and "Colorado" hand-held backpack sprayers and a "SOLO 416" motorized sprayer. Results showed that after treatment with Delcid, fly population recovery occurred within 35 days, compared to 20 days with Ciperil 10%. The delarvation efficiency of substrates, including manure storage facilities and larval breeding sites, was 70%. Test data on aqueous emulsions of Ciperil 10% and Delcid at concentrations of 0.005% and 0.125%, calculated at a rate of 12.5 ml per 10 liters of water, confirm the high effectiveness of insecticidal and mechanized means for disinfestation and delarvation.</jats:p>
