SUCKING PHYTOPHAGES OF OPEN-SEEDED TREES AND SHRUBS IN THE FERGANA VALLEY (LACHNIDAE, DIASPIDIDAE): FAUNA AND ECOLOGY

The article provides an ecological-faunistic analysis of sucking insects living on open-seeded plants in the Fergana Valley. In open-seeded trees and shrubs, 7 species of sap and 2 species of shield were recorded. Of these, Cinara pinicola Kalt., Carulaspis visci (Schrank, 1781) and Carulaspis minima (Targioni – Tozzetti, 1868) were first recorded in the Fergana Valley. Species with a single-stage food spectrum (Cinara picea, Eulachnus alticola, E.tauricus, Carulaspis minima, C.visci) are divided into ecological series of species with a two-step food spectrum (Cinara tujafilina) according to the degree of attachment of sucking insects to food plants. Seasonal changes in the quantitative densities of cinara tujafilina, Eulachnus alticola, E.tauricus sap were analyzed by Fisher's Z method and reliability levels were determined. On the basis of studies on the biology and ecological properties of all species of algae and thyroid, special studies on the entomophagous of the thyroid have been conducted and preliminary results have been obtained.
