WATER AND AMPHIBIOTHIC INSECTS (INSECTA: ODONTATA, EPHEMEROPTERA, PLECOPTERA, TRICHOPTERA, MEGALOPTERA, HEMIPTERA, COLEOPTERA) OF KRASNOGUBKA RIVER AS INTACT ECOSYSTEM

Abstract

The taxonomic composition of water and amphibiotic insects of the Krasnogubka River fauna on the territory of Berezinskiy biosphere reserve (Belarus) is discussed in the article. This river is an intact ecosystem. The criteria of intactness for river and stream ecosystems. have been developed.

The entomofauna of amphibious and water insects (excluding the Diptera) of the Krasnogubka River includes 78 species (Coleoptera — 28 species, Trichoptera — 24, Heteroptera — 9, Odonata — 6, Ephemeroptera — 6, Plecoptera — 4, Megaloptera — 1 species). Among them, indicators of water purity, are fixed such as Taeniopteryx nebulosa (Linnaeus, 1758), Chaetopteryx villosa (Fabricius, 1798), Odontocerum albicorne (Scopoli, 1763) and Deronectes latus (Stephens, 1829). In the river 8 species-indicators of intact river and stream ecosystems (Sialis nigripes, Taeniopteryx nebulosa, Chaetopteryx villosa, Odontocerum albicorne, Cordulegaster boltonii, Velia saulii Tamanini, 1947, Gerris sphagnetorum Gaunitz, 1947 and Deronectes latus) were revealed. Two species of Trichoptera (Psychomyia pusilla (Fabricius, 1781) and Chaetopteryx villosa) have been recorded for fauna of Berezinskiy biosphere reserve for the first time.
