Bioecological properties of nematodes of the sub-order filariat skrjabini, 1915 -mammal parasites in various biocenoses of Uzbekistan

This article reveals the many year‘s results of research and literature data on the fauna and bioecological features of filariat -parasites of mammals in various biocenoses of Uzbekistan. In mammals of Uzbekistan, 23 species of filariat were found belonging to 9 genera -Onchocerca, Dipetalonema, Dirofilaria, Litomosa, Parafilaria, Skrjabinodera, Micipsella, Setaria, Stephanofilaria and 5 families -Filariidae, Dipetalonemidae, Onchoceridae and Stephanarii. As the results of research show, among invertebrates, a significant role as intermediate hosts for mammalian filariat belongs to blood-sucking dipterans, related to the genera Lyperosia, Stomoxys, Haematobia, Aedes, Culex, Culicoides, Simulum, Anopheles, Odagmia, Friesia, which are closely related to mammals. The areas of the noted dipterans in all cases overlap the areas of the corresponding helminthes and practically coincide with the areas of mammals -the final hosts. This indicates that the causative agents of helminthiasis such as onchocerciasis, setariosis, stefanofilariasis, parafilariasis, dipetalonemia, and dirofilariasis have the potential opportunity to expand their areas. The presented materials have important scientific and practical value for the development of rational measures for the prevention of filariasis in productive animals, the pathogens of which develop with the participation of various invertebrates.
