Biotsenotic Relations Of Aphids (Homoptera, Aphidoidea) With Acclimatized Trees And Shrubs

Abstract

The acclimatization of plants causes the aphid fauna of the same area to change, i.e. the formation of a specific aphidofauna. Along with the acclimatized plants, adventitious species that are not specific to the fauna of this region are emerging and becoming dangerous pests, while some local species are specializing in the survival of aphids on newly introduced plants.

According to the results of the study, 6 families of the dendroflora of Tashkent, 96 species of 46 genera of dendrophilic aphid live in 63 species of 23 families, 46 genera of acclimatized trees and shrubs.

The biggest number of aphid species, namely 33, live in the representatives of Rosaceae, Salicaceae, Fabaceae. This means that fauna consists of 34.4% of this aphid species. The role of Rosaceae and Salicaceae in this region is of particular importance, as only 19 species of aphids live in Rosaceae, while 9 species of these insects are pests in Salicaceae.

In general, the expansion of insect nutritional spectrum coverage plays an important role in the stability of the quantitative density of insect populations.
