Synanthedon bicingulata (Lepidoptera: Sesiidae) is one of the major insect pest infliting on Prunus serrulata.This species attack the cambium of host plants in larval stage and weaken tree vigor. This study was conducted to figure out the injury characteristics of P. serrulata by investigating the damage rate and distribution of damage parts. For the survey of appearance period, we used delta traps with female-sex pheromone lure. Damage rate of S. bicingulatawas highest at site 5 (yanggu-gun) with 71%. And there was a large number of damaged part as DBH is large. The damage parts were distributed intensively below 50cm in height. Peak emergence period of male S. bicinigulatawas mid-september.
