Features of Betula pendula Roth cenopopulation entomocomplexes in Mari El Republic

The structure of entomocomplexes of Betula pendula Roth of various ontogenetic state in areas of Mari El Republic is described. 131 types of Insecta are connected with cenopolulation of Betula pendula. Trophic groups of insects, groups on food range width, a way of life and injuriousness, seasonal dynamics of activity of Carabidae are characterized. It is shown that a variety of Insecta complex in the cenopopulation of Betula pendula Roth both by ecological conditions of areas of a research, and anatomical-morphological features of trees of various ontogenetic state on which insects live is defined. It is suggested that for the organization of long monitoring of a condition of uneven-age wood plantings it is necessary to estimate not only a damage rate of trees, but to study a biodiversity, relative abundance of various ecological-trophic groups of insects.
