This article highlights the dynamics of the nematode fauna in the roots and rhizosphere of tomato in greenhouses. In the process of analyzing the distribution of nematodes in terms of the phases of tomato development, the largest number of individuals was determined at the budding stage. In each phase of the plant development, the following characteristic types of nematodes have been established: in the sprouting (germination) phase - Eudorylaimus labiatus, Heterocephalobus elongatus, Diplogaster longicaudata, Eucephalobus oxyroides, Psilenchus clavicaudatus; in the seedling phase - Geomonhystera villosa and Dorylaimoides elegans; in the budding phase - Xylorhabditis operosa, Panogralaimus armatus, Paraphelenchus pseudoparietinus, Nothotylenchus acris; in the flowering phase - Clarcus papillatus, Melonchulus solus, Mesorhabditis irregularis, Aphelenhoides subtenuis; in the phase of initial fruit development - Aphelenhoides limberi and Aph. saprophilus; in the ripening phase- Eudorylaimus centrocercus, Heterocephalobus filiformis, Chiloplacus lentus, Acrobeles complexus, Aphelenchus solani, Helicotylenchus nannus, Meloidogyne arenarie. Among the real parasites, nematode species, including Meloidogyne arenarei, Ditylenchus dipsaci, Pratylenchus pratensis, Psilenchus lavicaudatus, Bitylenchus dubius, Helicotylenchus nannus were identified.
