Аннотация

Subjects of the inquiry: Phytoncmatodcs, whcatcn agroccnosis, wild and weed plants. Aim of the inquiry: Study all complex of kind content of nematodes,populated plants, near root soil of the wheat and wild plants as wel, clearing out the role of wild cereals as reserves of parasitic kinds, causing damage to this culture and their distribution and ecological peculiarities. Method of inquiry: Phytohclmintological and ecological methods of study have been used in the research. The results achieved and their novelty: Have been carried out complex phytohclmintological research of wheat, accompanying it’s weeds, and wild plants in conditions of Uzbekistan; have been established the ecological groups of phytoncmatods and their trophic connections with wheat; have been revealed the change laws of qualitative and quantitative content of phytoncmatods in the period of vegetation of plants; found out the importance of weed and wild vegetation in formation of fauna complexes of phytoncmatodcs of wheat and their role in accumulation and distribution of nematodes invasion in agroccnosis; given assessment to an opportunity of use of morphometric parameters identification of parasitic kinds of nematodes. Practical value: The practical aspect of work allows to asses phytohclmintological status of grain cultures, to allocate the kinds having potential value, also establishing the distribution area of the parasitic nematodes allow to work out the prophylactic measures to fight against them. Degree of embed and economic effectivity: The results of researches of the author can be used at the account and preventive maintenance of phytohclmintoses, and also for an assessment of efficiency held agrotechnical, biological and chemical measures on agroccnosis. Sphere of usage: The results of the research can be used for forecasting of occurrence of the centers of nematode illnesses, organization of plant protection from nematodes, soil and ecological researches, in educational process in delivering courses on zoology of invertebrates, phytohelmintology, soil zoology and ecology at universities, agricultural institutes.
