In this scientific-research work, the nematode fauna of annual wild grasses growing in the biocenoses of the Karatepa mountain massif was studied. As a result of the research, in the biocenoses of the Karatepa mountain massif, Carthamus oxyasanthus Bieb, Strigosella tursestanica Litv., Capsella bursa-pastoris (L.) Medic., Bromus L., Ranunculus arvensis L. plants and 58 species of nematodes in their rhizosphere soil was determined. The identified species consisted of representatives of two classes (Adenophorea, Secernentea), 4 subclasses (Enoplia, Chromadoria, Rhabditida, Diplogastria) and 6 families (Dorylaimida, Mononchida, Monhysterida, Araeolaimida, Rhabditida, Tylenchida). The identified nematodes were divided into groups of bacteriotrophs, polytrophs, predatory nematodes, mycohelminths and parasitic nematodes according to their nutrition and ecological characteristics. Parasitic nematodes, in turn, are divided into ectoparasites, those that feed on the root epidermis, migratory and sedentary endoparasites. There are many species found in all regions of the Karatepa mountain massif Species of the genera Ditylenchus, Pratylenchus, Aphelenchoides (Ditylenchus intermedus, D. dipsaci, Pratylenchus vulnus, P. pratensis, P. thornei, Aphelenchoides parietinus) with a large number of individuals were recorded in vegetative parts of plants.
