Saproxylic insect species of Köyceğiz and Fethiye Anatolian sweetgum forests in Muğla province

In this study, it was aimed to reveal the contribution of Anatolian sweetgum tree Liquidambar orientalis forests to saproxylic Coleoptera insect diversity. The study was carried out in selected old (d age; 36.0-51.9 cm diameter at breast height) Anatolian sweetgum forests in Köyceğiz and Fethiye. In order to sample insects, five trees were selected in both areas and two trap types (Window and Pitfall trap) were used on each tree. Traps were installed on March and checked once a month for six months (April-September). In addition to the traps, standing and fallen dead trees were examined in both areas and 22 individual collected. In addition, on July 23 saproxylic beetle, mostly Cerambycidae and Elateridae, were obtained using the light trap method in the Fethiye area. At the end of the sampling periods, 1 302 individuals, representing 109 species in 33 families were obtained. Seventeen beetle species were determined new records for the Turkish fauna. 1 219 individuals from 97 species were collected with window type traps and 38 individuals from 19 species with pitfall traps. The traps set in Köyceğiz yielded 765 individuals belonging to 73 species, whereas 492 individuals belonging to 71 species were obtained from the traps set in Fethiye. Curculionidae (555), Anobiidae (325) and Tenebrionidae (104) were the most commonly found families. The highest number of species were from Anobiidae (15), Elateridae (14), Curculionidae (8) and Staphylinidae (8). Xyleborinus saxesenii (Scolytinae) has the highest number of individuals with 492. Propomacrus bimucronatus from the Euchiridae family are in the IUCN red list of Vulnerable (VU).
