TO KNOWLEDGE OF THE FAUNA OF СURCULIONOIDEA BEETLES (INSECTA: COLEOPTERA: СURCULIONOIDEA) FROM THE TERRITORY OF THE POLESSKY STATE RADIATION AND ECOLOGICAL RESERVE, REPUBLIC OF BELARUS

Abstract

The research was carried out on the territory of the Khoiniki part of the Polessky State Radiation and Ecological Reserve (PSRER). The territory belongs to the VII Polesye-Dnieper geobotanical district (Gomel region). The materials were collected from 2007 to 2024 by standard methods accepted in entomological researches. The identified species belong to two families: Brentidae (7 species) and Curculionidae (38 species). One species is registered for the first time for the fauna of the Republic of Belarus – Cionus clairvillei Boheman, 1838, which is a monophage on the medicinal mullein, or hairy mullein (Verbascum phlomoides Linnaeus, 1753) and has a central-southern European geographic range. Forty-two species of weevils were recorded for the first time in the PSRER, and 9 species were recorded for the first time for the Poliesko-Dnieper Geobotanical District (Aspidapion aeneum (Fabricius, 1775); Perapion oblongum (Gyllenhal, 1839); Thryogenes festucae (Herbst, 1795); Hypera melancholica (Fabricius, 1792); Lixus tibialis Boheman, 1843; Lixus albomarginatus Boheman, 1842; Eusomus ovulum Germar, 1824; Charagmus gressorius (Fabricius, 1792); Sitona callosus Gyllenhal, 1834). A very rare species for the fauna of Belarus, Centricnemus leucogrammus (Germar, 1824), was found, it is typical for the forest-steppe and steppe zones; it is polyphagous mainly on herbaceous plants of the Cistaceae, Fabaceae and Lamiaceae families. An alien species, Aspidapion aeneum (Fabricius, 1775), has been found. It has distributed quite widely in the Belarusian territory and it is a narrow oligophage on Malvaceae. It is registered for the first time in the Polesie-Dnieper Geobotanical District. According to trophic specialization, the majority of species are oligophages – 57.1%, polyphages consist of 31%; monophages – 11.9%.
