BIOLOGICAL DIVERSITY OF SOIL MACROFAUNA OF SAMARKAND REGION

Abstract

The systematic composition, ecology and economic significance of the soil macrofauna of the gardens of the Samarkand region were studied. The study revealed 28 species of garden soil macrofauna belonging to 8 families and 20 genera. 9 species of terrestrial molluscs: 6 families and 6 generations; 5 types of earthworms: 1 family and 3 generations and 14 insects: 1 family and 10 generations. As new species for the study areas, 4 species of earthworms, 4 species of terrestrial mollusks and 6 species of insects were identified. Comparison of species distributed in the biocenosis and agrobiocenosis gave the following results. In the distribution of soil macrofauna of gardens in the Samarkand region in biocenoses, 28 species by species: 14 insect species in nuts and almonds, 5 earthworm species and 9 land mollusk species, 10 species in agrocenoses: 6 insect species in diamonds, vineyards and apricots 6 insect species were registered , 9 species of terrestrial molluscs. In the gardens, first laid out on the hills, macrofauna was sparse, only earthworms and insect larvae.
