  This study was performed to investigate the emergence timing and daily emergence from the different tree species logs (Korean white pine, Pine, and Japanese larch) at Cheongwon, Chungcheongbuk-do from 2006 to 2008. Pine sawyer adults began to emerge on early May (2~10th day) and finished on mid-June (4~20th day) in the Korean white pine and pine logs. However, pine sawyer adults began to emerge on mid-May (13th day) and finished late May (27th day) in Japanese larch logs. Japanese larch logs shows shorter emergence timing of pine sawyer adult compare to those of other two tree species. Emergence timing shows no difference between males and females. Sex ratios of emerged adult in 2007 were 0.55 from Korean white pine, 0.46 from Pine, and 0.59 from Japanese larch, it shows no difference among tree species. Female and male adults emerged throughout 24 hrs, 22.8% of the total adults emerged from 12~14:00 (22.8%) and adults emerged lowest from 06~08:00. Of the adults emerged from the logs, 98.9% was univoltine and the rest was biennial which emerged next year.
