FAUNA AND SEASONAL DYNAMICS OF THE COLLEMBOLANS OF UZBEKISTAN

Abstract

The article provides information on the species and quantitative composition of the collembolan communities of various soil layers of agrocenoses and natural ecosystems of northeastern Uzbekistan. As a result of research, 33 species were found in the clover agrocenosis soil layers, 30 in the soil layers of cotton fields, 31 species in the soil layers of apple orchards, and 49 soil species were found in the soil ecosystems of natural ecosystems. The agrocenoses and soil layers of natural ecosystems were dominated by such species as Isotoma notabilis, Isotomiella (Isotoma) minor, Folsomina onychiurina, Frisea (Triaeana) mirabilis, Xenyllodes armatus, Folsomina candida, Willmia anophtalma, Xenylla maritima, Oligaphorura (Lipura) groenlandica, Isotomodella pusilla, Panchaetoma (Isotoma) communa, Schoettella (Achorutes) ununguiculatus, Acherontiellina (Acherontiella) sabina. When studying the number of collembolans by seasons, the peak period of their seasonal dynamics is observed in spring and autumn, and when studying soil layers (10-20 cm), the number of collembolans was at its maximum, in spring and autumn in agrocenoses and soils of natural ecosystems in soil at a depth of 10-20 cm number of collembolans in spring was on average 3558 copies, and in the autumn there were 3298 copies.
