Abstract
Study of the species composition and diversity of insect communities in herb-shrub layer was conducted. Three hundred seventy four species from 10 orders were revealed. Coleoptera, Diрtera, Heteroptera and Auchenorrhyncha predominated. From 2 to 8 species prevailed in each order. These were Cixius similis Kirschbaum, 1868 , Neophilaenus lineatus (Linnаeus, 1758) , Lepyronia coleoptrata (Linnаeus, 1758) (Auchenorrhyncha), Lygus pratensis (Linnаeus, 1758) , Kleidocerys resedae (Panzer, 1797) , Stictopleurus crassicornis (Linnаeus, 1758) (Heteroptera), Lochmaea suturalis (Thomson, 1866) , Cyphon padi (Linnаeus, 1758) , and Plateumaris discolor (Herbst, 1795) (Coleoptera). The communities had a low species diversity and distribution of species by abundance. The most similar were insect complexes of habitats with herbs as well as habitats with predominant of dwart shrubs. A regression analysis showed a significant relation between species richness and diversity of insects and species composition of plants and their projective cover degree. Various methods of multivariant analysis (CCA and PCA) demonstrated the influence of these еnvironment variables on the spatial distribution of concrete species and their preferences of certain habitats.
