Özet: Dendroctonus micans has been continuously colonizing the native oriental spruce forests after its discovery in 1966 in Turkey. Solitary females attack the trees and they usually do not kill its hosts. This study aims to contribute the understanding of this solitary attack strategy and development of D. micans on oriental spruce in Turkey. The pattern of tree infestation was analyzed from 2001 to 2004 and 2006 in 120 experimental plots. Field surveys were carried out in the north east of Turkey in Artvin, Giresun, and Maçka (Trabzon) from May to October of each year. A total 3010 trees were examined in plots. D. micans infestation up to 2 m of trees were examined and the successful and aborted attacks were recorded. Development stages and numbers of the beetles were recorded in the galleries. The sizes of the old brood chambers were measured in the abandoned and infested trees
