THE TROPHIC STRUCTURE OF THE SUBCORTICAL ENTOMOFAUNA OF COLEOPTERA IN THE DECIDUOUS PLANTATIONS OF THE HOMILSHA WOODS NATIONAL NATURE PARK

Abstract

The research was carried out in 2019/2020 in the Homilsha Woods National Nature Park in the plantings with different levels of anthropogenic load: an economic area (with selective sanitary felling in 2017); ‘recreation + felling’ in winter 2019); a protected area; an area of regulated recreation; an area of stationary recreation. A total of 63 species from 49 genera of 23 families of subcortical Coleoptera with the predominance of Cerambycidae and Curculionidae: Scolytinae were identified. Xylophages (23 species, or 36.5%) and entomophages (16 species, or 25.4%) predominated in terms of the number of species. Saproxylophages included 13 species (20.6%), xylomycetophages – 7 species (11.1%), myxomycetophages – 3 species (4.8%), mycetophages – 1 species (1.6%). Xylophages are represented in four families, xylomycetophages in two ones, entomophages in eight ones, saproxyphages in eight families, and mycetophages in one family. In the area of regulated recreation, 37 species of subcortical Coleoptera were identified (58.7%), in the areas of stationary recreation and protected area – 25 and 32 species, or 39.7 and 50.8%, respectively. In the plantings of economic and recreational ones, where selective felling was carried out, 27 and 25 species were identified respectively (42.9 and 39.7% of the total number of detected species). In the economic and recreational areas, where selective felling had just been carried out, xylophages accounted for 51.9 and 56%, and entomophages for 18.5 and 20% of all subcortical Coleoptera species found in each area. In the protected area and the area of regulated recreation, xylophages make up 25 and 29.7% respectively, and entomophages – 28.1 and 24.3%, respectively. With the help of the Sorensen-Chekanovsky index, the plantings with the high similarity of the subcortical fauna of Coleoptera were determined as: 1 – areas of economic and recreational areas where felling was carried out, and 2 – areas of the protected area and regulated recreation area.
