Abstract
The biology and ecology of parasitic insects are closely related to the life of people, and the leading role belongs to animal husbandry. It is difficult to overestimate the negative influence of parasitic dipterans on productive animals, especially during the season of their mass reproduction and distribution. The work aimed to study the species composition of Diptera in different livestock biocenoses in eastern and central Ukraine. Entomological nets and traps were used to capture zoophilic flies, the number of insects was determined using the fly index, and luminescent markers TAT 33 with a powder fraction of 30 microns. The collected insects were identified according to the existing modern identifiers. As a result of the studies, the presence of Musca domestica (Linnaeus, 1758) was determined in all livestock facilities for keeping animals and birds. The largest number of house flies was noted in the facilities for keeping sows with suckling pigs (312.0±35.3) and fattening animals (277.5±6.1). M. domestica, M. autumnalis, and S. calcitrans accounted for 75.57% of the entire complex of zoophilic flies. The species M. vitripennis, M. tempestiva, L. irritans, H. atripalpis also occupied an important place among the species that form the entomoparasitocenosis (18.91%). In pasture biotopes, two species of flies (Ortellia caesarion Meigen and Ortellia cornicina Fabr.) have been identified. They do not attack animals, but are mineralisers of cattle feces. Luminiferous marker L-1 basic green (TAT 33) fixes well on insects and lasts for 5 days. The density of the fly population in the pig houses is 36% higher than in the calf houses. The results obtained are the basis for the development of innovative, scientifically grounded schemes for control and the fight against parasitic insects at livestock enterprises
Highlights
Today, there are approximately 1.5 million, 5.5 million, and 7 million species of beetles, insects, and terrestrial arthropods in the world, respectively [1]

Summary
There are approximately 1.5 million, 5.5 million, and 7 million species of beetles, insects, and terrestrial arthropods in the world, respectively [1]. Among a large number of insects, some are herbivores and provide invaluable benefits to the ecosystem [2]. Some insects feed on organic substrates or are predators of other species [3; 4]. True flies (Muscidae), one of the large families of the suborder Diptera (Brachycera), are distributed throughout the world, and about 5000 species from 100 genera have been described in the world fauna [6; 7]. Flies can lay eggs on several types of substrates, which in turn allows them to colonise many regions [9]. There is competition between different species of flies in nature, which manifests itself in behavioral characteristics during feeding and reproduction [10]
