Abstract: In this study, bark and ambrosia beetle species collected by red winged sticky traps in Quercus cerris L. forests of Aksu District in Isparta Province, South-Western Turkey during the years 2011 and 2012 were evaluated. A total of 8 species belonging to 3 tribe of the Scolytinae were recorded. All collected species were found the first time in Isparta Province. Among those species, Taphrorychus ramicola (Reitter, 1894), T. villifrons (Dufour, 1843), Scolytus intricatus (Ratzeburg, 1837), Anisandrus dispar (Fabricius, 1792), Xyleborus dryographus (Ratzeburg, 1837) and X. monographus (Fabricius, 1792) were recorded as new species for the Scolytinae fauna of the Western Mediterranean region of Turkey. X. dryographus was also found the first time in the whole of Mediterranean Region and Southern part of country. T. ramicola and Scolytus rugulosus (Muller, 1818) were determined the first time on Quercus cerris in the world by this study. In addition to these two species, S. intricatus, X. dryographus and X. monographus were recorded on Q. cerris in Turkish forests for the first time. Among the collected specimens, X. saxesenii (Ratzeburg, 1837) (64.3%), A. dispar (Fabricius, 1792) (28.25%) and T. villifrons (5.13%) were found as abundant species.
