The first occurrence of oak wilt disease(OWD) in Korea was reported in 2004 and a Platypodid beetle, Platypus koryoensis, was known to contribute significantly the occurrence of the disease. To reduce the oak wilt disease, it is necessary to control density of P. koryoensis under injury level. This experiment conducted to clarify the flying period of adult P. koryoensis. Four forests containing dead trees by OWD were selected and the location of the experimental sites were Mt. Surak in Seoul, Goyang-si, Paju-si in Gyeonggi-do, Hongcheon-gun in Gangwon-do. Sticky trap or vertical multi-funnel trap was settled on Quercus mongolica trees located in infested forest. Density of P. koryoensis was survey with one or two week interval from May to October in 2007 and 2008. The number of the beetle collected by the vertical trap and sticky trap was positively correlated (r2=0.69). The optimum flying period of the beetle was ranged from late June to late July with geographical variations.
