The aim of this study was to determine the diversity of bark beetle predators in the coniferous forests of the Balikesir Province of Turkey. Six plots were established that each contained five pheromone traps and two log traps. Eight bark beetle predator species: Aulonium ruficorne, Clerus mutillarius , Corticeus fraxini, Paromalus parallelepipedus, Platysoma elongatum, Raphidia ophiopsis, Temnochila caerulea and Thanasimus formicarius, belonging to six families were found. The six bark beetle predator families found were: Cleridae, Trogossitidae, Laemophloeidae, Tenebrionidae, Zopheridae, Histeridae, and Raphidiidae. Also it is included a description of which bark beetle galleries these predators were found in.
