Faunistic studies on Carabidae, Cerambycidae, Curculionidae, Elateridae, Scarabaeidae and Staphylinidae (Coleoptera) families detected by pitfall and bait trapping methods in Balya region (Balıkesir Province) in Türkiye

This study was carried out in oak fields located in the Balya region of Balıkesir province of Turkey. Our study aimed to identify species belonging to the Coleoptera order using bait and pitfall traps. Our research was conducted between 28 May-19 October(2019) and 10 May-21 October(2020). As a result of the study, 37 species belonging to 26 genera from the families Carabidae, Cerambycidae, Curculionidae, Elateridae, Scarabaeidae and Staphylinidae, included in the Coleoptera order, were recorded. Among the identified species, 31 species were recorded in Çamavşar and 29 species in Kocaçay. The pitfall trap was more effective than the bait trap in capturing the species. While Polydrusus gracilicornis Kiesenwetter, 1864 was detected only in the bait trap, 9 different species were recorded in both trap methods. 17 of the 37 species identified are saproxylic insects. 6 of these species are on the red list of the International Union for Conservation of Nature (IUCN). These species include Cerambyx cerdo Linnaeus, 1758 NT (near threatened), Hesperophanes sericeus Fabricius, 1787, Hylotrupes bajulus Linnaeus, 1758 and Icosium tomentosum Lucas, 1854 species LC(common) from the Cerambycidae family; Ampedus praeustus (Fabricius, 1792) and Lacon punctatus (Herbst, 1779) species from the Elateridae family are in the LC category.
