Abstract
The article presents data on the species and quantitative composition of nematode communities of soil layers of agrocenoses and natural ecosystems of the foothill regions of the Tashkent oasis of the Republic of Uzbekistan. As a result of studies, it was revealed that 54 species are widespread in the soil layers of wheat fields, 45 species in tomato fields and 65 species of nematodes in natural ecosystems. In the seasonal dynamics of the number of nematodes, spring and autumn peaks are observed, when the number of nematode individuals is several times higher compared to the summer and winter periods. Autumn temperature drop and a slight increase in soil moisture contribute to a new increase in species diversity and number of phytonematodes. A decrease in species diversity and number of phytonematodes in winter is associated with a decrease in temperature and the absence of a power source. The vertical distribution of soil nematodes and their accumulation in a particular soil layer, first of all, depends on the presence of the root system of plants, the optimum temperature and humidity of the soil and air. Various ecological groups of nematodes and their individual species do not react equally to changes in the conditions of existence, as the dynamics of para-isobionts were maximal in the spring, while in eusaprobionts, there was a small group that included only 4 species (4.1%) of nematodes. The species composition of devisaprbionts is more diverse in the spring and autumn. Phytohelminths are represented by 40 species (40.8%), in the dynamics of their species composition there are no sharp fluctuations that were observed in other ecological groups. The maximum number (27) of species is confined to the spring period. The difference in species diversity and the number of phytonematodes in different plants, soil layers and seasons was determined, which is associated with vegetation, changes in humidity and temperature in different soil layers.

Key words: Nematode, species composition, seasonal dynamics, agrocenosis, natural ecosystem, para-isobiont, eusaprobiont, devisaprobiont, phytohelminth, Tashkent oasis.
