Аннотация

Subject of research: The biocenotic complex of the plant nematodes of the wheat and barley under conditions of the irrigated bogharic land and un-irrigated soil in the foot-hill soil, analysis of the taxonomic and ecological composition of plant nematodes, revealing of plant nematodes, an opportunity of using the Anguina picridis in the organization of the weed control of the Russian centaury. Purpose of work: study of the biocenotic complex of plant nematodes of the wheat and barley under conditions of the un-irrigated bogharic lands and irrigated adyrs in the foot-hill zone, the analysis of the taxonomic and ecological composition of plant nematodes, revealing of parasitic species and opportunities of using the Anguina picridis in the organization of the weed control of the Russian centaury. Methods of research: Common methods applied in the phytohelminthological and ecological studies and static analysis of data obtaining were used Results obtained and their novelty: A comparative study of biocenotic complexes of plant nematodes in agroecosystems of wheat and barley in different soil-hydrothermic conditions of the foot-hill zone of Uzbekistan was conducted; regularities of changes of the species ecological composition of plant nematodes depending on the conditions of plant growth were established; an idea was expressed on possible use Anguina picridis for the control of Russian centaury Practical importance: An integrated study of plant nematodes of cereals enables revealing the importance of separate species and ecological groups in agroecosystems; the study of biology and ecology of parasitic species gives an opportunity of developing measures of their control. Level of embed and economic effectivity: The results of the study can be used for the revealing of the importance of plant nematodes in agroecosystems and for the prognosis of the emergence of focuses of diseases caused by plant nematodes and their control. Obtained data can be used in soil and ecological studies, as well as in the educational process when delivering lectures on zoology, ecology and soil zoology for the students of biological and higher educational agricultural institutions. Field of application: the results of the study can be used for the prognosis of the emergence of diseases caused by plant nematodes in agroecosystems, as well as in soil-ecological studies and delivering lectures on zoology, plant nematology and ecology at universities and higher educational agricultural institutions.
