ENTOMOFAUNA (INSECTA: EPHEMEROPTERA, ODONATA,PLECOPTERA, HEMIPTERA, COLEOPTERA, MEGALOPTERA, TRICHOPTERA)OF INTACT WATER ECOSYSTEMS OF SOME SPECIALLY PROTECTEDNATURAL AREAS OF BELARUS

Abstract

The water and amphibiotic entomofauna (Ephemeroptera, Odonata, Plecoptera, Hemiptera, Coleoptera, Megaloptera, Trichoptera) of intact natural water ecosystems in the territory of the Berezinsky biosphere reserve, the National park “Pripyatsky” and the Republican landscape reserve “Stronga” is discussed in the article.

In intact natural water bodies in the Berezinsky biosphere reserve 200 species of water and amphibiotic insects
have been recorded, in the landscape reserve “Stronga” — 113 species, in the territory of the Pripyatsky national park —
71 species.

In the study of specially protected natural areas 11 species — indicators of intact natural watercourses
(dragonflies Cordulegaster boltonii (Donovan, 1807) and Ophiogomphus cecilia (Fourcroy, 1785), spring-grass Taeniopteryx nebulosa (Linnaeus, 1758), bugs Velia saulii Tamanini, 1947 and Gerris sphagnetorum Gaunitz, 1947,
beetles Deronectes latus (Stephens, 1829), Nebrioporus assimilis (Paykull, 1798) and Hydraena gracilis Germar,
1824, alderfly Sialis nigripes Pictet, 1865, caddisflies Chaetopteryx villosa (Fabricius, 1798) and Odontocerum
albicorne (Scopoli, 1763)), the indicator of intact rivers, old river-beds, lakes and bogs — dragonfly Brachytron
pretense (Müller, 1764), the intact dystrophic lakes indicator — caddis Agrypnia obsolete Hagen, 1864, three
indicators of intact upland and transitional bogs (beetle Ilybius wasastjernae (Sahlberg, 1824), dragonflies Aeshna
subarctica Walker, 1908 and Somatochlora arctica (Zetterstedt, 1840)) have been recorded.

The main directions of transformation of communities of model groups of water and amphibiotic insects in
natural water ecosystems under anthropogenic impact are determined.
