BIOLOGICAL PECULIARITIES OF SOME CATTLE NEMATODE SPECIES IN UZBEKISTAN DEVELOPING WITH THE PARTICIPATION OF DIPTHERS

This article presents the results of many years of our own research and literature data on the biological characteristics of some types of nematode parasites of cattle, developing with the participation of Diptera insects in the biocenoses of Uzbekistan. In cattle of Uzbekistan, 71 species of helminths are registered, of which 12 species belong to the class Cestoda Rudolphi, 12 species to the class Trematoda Rudolphi, 1808 and 47 species to the class Nematoda Rudolphi, 1808. their adaptation to a variety of environmental conditions, contributing to the development of parasites in all phases of life cycles. Of the identified 47 species of cattle nematodes in Uzbekistan, 10 species develop with the participation of dipterous insects. Biological features are highlighted - Onchocerca lienalis (Stiles, 1892), Stephanofilaria stilesi Chitwood, 1934, Stephanofilaria assamensis Pande, 1936, Thelazia rhodesi (Desmaresi, 1827), Parabronema skrjabini (Rassowska, 19240) and Setaria labiatopapillosa (Alessandrini, 1838) - bovine parasites livestock developing with the participation of dipterous insects in various biocenoses of Uzbekistan. The data obtained by us will serve as a scientific basis for planning and carrying out therapeutic and prophylactic measures against pathogens of nematodosis in cattle and other ruminants that develop with the participation of Diptera in specific biocenoses of Uzbekistan.
