Voronova N. Ecology of larvae Culicidae Diptera of the upper reaches of the Kakhovsky reservoir.

Bloodsucking mosquito's (Culicidae, Diptera). To find out a possibility of use of modifications fauna, phenology and morphology Culicidae for an evaluation of a condition water and near-water ecosystems. A common technique of researches. Microscope, COMPUTER. Due to the use of sinecological indices the analysis of forming the fauna of the Culicidae for all period of the Kakhovsky reservoir exis-tence has been conducted. The phenology of 18 species of bloodsucking mos-quito's was established. It was made the scheme for preimaginal phases, where the changes in the phenology of the se insects are shown for last 20 years. Ecological peculiarities of larvae were established in the area of research. There also was marked the influence of the pH value content of dissoluble oxygen on larvae den-sity of two mass species of Aedes. In the present work the analysis of the content of 8 morphological properties of larvae of the 4th stage of 7 species Culicidae has been made. The analysis shows the absence of the act ion stabilizing selection, and no stability of the conditions of their existence. The use of the index of specializa-tion index nutrition was proposed for estimation of the reservoirs state, and also for the changes of the fauna end phenology, morphology for prognostication an epi-demiological situation of the region with a heavy anthropogenic load. The schemes of biogeocenotic connections of bloodsucking mosquito's have been elaborated. The results of the present work found their introduction in the work of sanitary-epidemiological service and in the study processes.
