Фауна пластинчатоусых жуков (Coleoptera, Scarabaeoidea) городских и целинных территорий Юго-Востока Украины

Abstract

As а result of investigation carried out during 1986 to 1997, 61 species of scarabaeids have been found, in the territory of Donetsk and Makeevka towns in the Kamennye Mogily Reservation -80, in те Streltsovskaya Step Reservation -73, in the Provalskaya Step Reservation -80, in the Khomutovskaya Step Reservation -70. The comparison of urban and steppe territories showes significant decrease in quantity of xerophyle steppe species in towns, as well as absence of а number of species common for both reservations and agricultural territories: Heptaulacus sus (Herbst), Gymnopleurus mopsus (Pall.), Onthophagus semicornis (Panz.), Caccobius schreberi (L..), Aphodius hydrochoeris (F.), A. sordidus (F.), A. ictericus (Laich.), A. sturmi Har., Blitopertha lineata (F.), Anisoplia segetum (Herbst.), A. agricola (Poda.), Potosia metallica (Herbst.), P. hungarica (Herbst.). In urban fauna, thanks to presence of lots of wood growih and traces of ravine forests which covered town territories in the past, а number of typical forest species still exit. They have their extreme south border of distribution in Steppe Zone: Lucanus cervus (L.), Dorcus parallelopipedus (L.), Geotrupes stercorarius (L), G. stercorosus Scriba., Aphodius brevis Er., A. rufipes (І..), A. depresus (Kug.), A sticticus (Panz.), Oxyomus silvestris (Scop.) Urban fauna has minimal species diversity and minimal index of mean value for Jackar's coefficient, as compared with steppe territories (Kj=0,61).
