Type: conference-paper
Abstract: The article provides data on the species composition, ecological groups, and distribution of plant nematodes in cabbage agrocenoses in Eastern Fergana. The result identified 39 plant nematode species that belonged to two subclasses, 7 orders, 15 families and 25 genera. In terms of species composition, representatives of the orders Rhabditida, Dorylaimida and Tylenchida dominated. Aphelenchida species had an average abundance; species of Plectida, Mononchida and Enoplida orders had the lowest abundance. Most of the identified species were distributed in the root system and rhizosphere. The above-ground organs and the root system of the cabbage mainly contained species of the genera Rhabditis, Panagrolaimus, Chiloplacus, Aphelenchus, and Ditylenchus. In terms of nutrition and ecology, pararhizobionts and devisaprobionts predominated; eusaprobionts, nonspecific and true phytohelminths were less common. Of true parasites, the most common species were Ditylenchus dipsaci, Meloidogyne hapla, and M. incognita. Of which, species of the genus Meloidogyne were more often found in the Jalaquduq and Asakinsky Districts, and the infection of cabbage roots by these nematodes was observed. Plant nematodes in cabbage agrocenoses were uneven in species and quantity. By region, number of species and their composition, the most common parasites were found in agrocenoses of the low adyr zone.
