Аннотация

Subjects of research: Coccinellidae of biocenoses and agroecosystems of Bukhara oasis, sucking pests of plants. Purpose of work: the main purpose is the study of the fauna, ecology and industrial importance of Coccinellidae in Bukhara oasis. Methods of research: entomological and ecological methods of studies are used in the work. The results obtained and their novelty: forty-one Coccinellidae spp. of 2 subfamilies, 9 tribes, of which 33 are common and 8 are rare, and 14 have first been recorded under conditions of Bukhara oasis. It was for the first time established that Coccinella septempunctata feeds on 93 aphid species of 5 families of the suborder Aphidinae. Besides, trophic links of Adonia variegata and Chilocorus bipustulatus have been established. The confinement of Coccinellidae species to habitats, as well as to different types of wintering grounds, has been established. Causes of large-scale death of Coccinellidae from the effect of anthropogenic factors have been revealed and methods of protection and improvement of their effectiveness against the pests of agricultural crops suggested. Practical value: conservation of Coccinellidae biodiversity and increase in the numbers of their species in agroecosystems enables the decrease in the numbers of pests of agricultural crops. Degree of embed and economic effectivity: the results of this study on the revealing of the role of local Coccinellidae species in Bukhara oasis, their protection and involvement in pest control yield a significant economic effect. Field of application: environmental protection, education, scientific studies.
