PHYTOPHAGES (LACHNIDAE, DIASPIDIDAE) OF OPEN-SEEDED TREES AND SHRUBS IN THE FERGANA VALLEY: FAUNA AND ECOLOGY
Abstract
In the article, sucking insects living in open-seeded plants in the conditions of the Fergana Valley are analyzed ecologically and faunistically. 7 species of aphids and 2 species of aphids were recorded in open-seeded trees and shrubs. Among them, Cinara pinicola Kalt., Carulaspis visci (Schrank, 1781) and Carulaspis minima (Targioni-Tozzetti, 1868) from the shields were recorded for the first time in the Fergana Valley.
According to the degree of attachment of sucking insects to food plants, species with a one-step feeding spectrum (Cinara picea, Eulachnus alticola, E.tauricus, Carulaspis minima, C.visci) and species with a two-step feeding spectrum (Cinara tujafilina) are divided into ecological series. Seasonal changes in the density of Cinara tujafilina, Eulachnus alticola, E.tauricus saps were analyzed by Fisher's "Z" method, and confidence levels were determined.
On the basis of studies on the biology and ecological characteristics of all species of aphids and aphids, special studies on entomophages of aphids were conducted and preliminary results were obtained.
