Nematodes Used as Test Objects for Parasitological and Biological Studies (literature review)

The purpose of the research is reviewing national and foreign literature on nematodes used as test objects for parasitological and biological studies.Statistics is given on the importance of nematodes in the agricultural sector; the role is shown that nematodes play as biological models in studying fundamental processes in biology, screening chemicals against phytohelminths, and searching agents of biological control of phytonematodes. A description is given of direct and indirect relationships between nematodes and mycorrhiza-forming fungi. A detailed description is provided of mycohelminth application in fungoid disease control, and creation of nematode-resistant varieties and agricultural crop hybrids. The perspectives of using nematodes as test objects for parasitological and biological studies are shown
