Abstract:
Forest ecosystems fulfill their functions by creating a number of important habitat types and also have key roles in sustainable development. Pest insects are among the main factors which affect the health of forests in Turkey. Bark and wood-boring beetles (Coleoptera: Bostrichidae; Curculionidae: Platypodinae and Scolytinae) have quite a significance among the harmful species to widespread on forest trees in Turkey. The aim of the study is to describe the diversity and compare the similarity of bark and wood-boring beetles fauna in two endemic [Sweetgum (Liquidambar orientalis Mill.) and Kasnak oak (Quercus vulcanica (Boiss. and Heldr.ex) Kotschy)] and one relict [Oriental beech (Fagus orientalis Lipsky)] deciduous forest tree species of Mediterranean region. Field studies were conducted in two different stands of Sweetgum (Muğla-Köyceğiz and Isparta-Sütçüler provinces) and one for each Kasnak oak (Isparta-Eğirdir province) and Oriental beech (Kahramanmaraş-Andırın province). In order to determine the bark and wood-boring beetles spread over these stands, ethanol baited red winged sticky traps were used. In addition, specimens were taken from drying or fallen trees. The red winged sticky traps used in the study are consisting of two crossing rectangles with dimensions of 15 × 21 cm made of red plastic and were made more attractive with a mixture of ethyl alcohol and toluene. A white cylindrical cup of 9 cm diameter and 18 cm depth with 4 holes of 2 cm diameter was hung underneath the trap and half of the cup was filled with a water mixture of 96% ethyl alcohol and 1% toluene. Based on the material collected from research areas between 2011 and 2016, a total of 22 species from Bostrichidae and Curculionidae families were identified. 6 species belonging to 3 tribe of Bostrichinae subfamily and also 1 tribe of Lyctinae subfamily from Bostrichidae; 2 species of Platypodinae subfamily and 14 species belonging to 5 tribe of Scolytinae subfamily from Curculionidae were determined. These species are; Amphicerus bimaculatus (Olivier, 1790), Bostrichus capucinus (Linnaeus, 1758), Lyctus linearis (Goeze, 1777), Sinoxylon muricatum (Linnaeus, 1767), Scobicia chevrieri (Villa&Villa;, 1835), Xylopertha retusa (Olivier, 1790) (Bostrichidae: Bostrichinae); Platypus simulans Schedl, 1941, Platypus cylindrus (Fabricius, 1792) (Curculionidae: Platypodinae); Anisandrus dispar (Fabricius, 1792), Dryocoetes villosus (Fabricius 1792), Hylesinus crenatus (Fabricius, 1787); H. varius Fabricius, 1775, Hypoborus ficus Erichson, 1836, Scolytus intricatus (Ratzeburg, 1837), S. mali (Bechstein 1805), S. rugulosus (Müller, 1818); Taphrorychus ramicola (Reitter, 1894); T. villifrons (Dufour, 1843); Trypodendron signatum (Fabricius 1787), Xyleborus monographus (Fabricius, 1792), X. xylographus Say, 1826 and Xyleborinus saxesenii (Ratzeburg, 1837) (Curculionidae: Scolytinae). Among Bostrichidae species, both of A. bimaculatus and X. retusa were found at Oriental beech stand in Andırın and at sweetgum stand in Köyceğiz. B.capucinus specimens were determined in Kasnak oak, Oriental beech and Köyceğiz sweetgum stands. L. linearis was found in both Kasnak oak and Oriental beech stands. S. chevrieri specimens were determined in both sweetgum stands in Köyceğiz and Sütçüler provinces, by the way S. muricatum was found only in sweetgum stand of Sütçüler. As member of Platypodinae (Curculionidae) species, Platypus simulans was collected from only sweetgum forest of Sütçüler province whereas P. cylindrus was found in only Oriental Beech stand in Andırın. Among Scolytinae (Curculionidae) species, Anisandrus dispar and Xyleborinus saxesenii were found all four studied stands. Scolytus intricatus, Taphrorychus ramicola, T. villifrons and Trypodendron signatum specimens were collected from both Kasnak oak and Oriental beech stands. Dryocoetes villosus, Hylesinus crenatus, H. varius, S. mali and S. rugulosus were determined in only Kasnak oak stand of Eğirdir province. Hypoborus ficus and Xyleborus xylographus specimens were collected in only Sweetgum forest in Sütçüler province, whereas X. monographus was found in only Oriental beech stand in Andırın province.
