Bark beetles are recently considered as important forest insect pests in several countries. Damage of bark beetles has increased in Korea, and monitoring of these beetles become important. However, there has been no study on development of monitoring skill on bark beetles in Korea. In this study, we tested the attractiveness of (-)-α-pinene, ethanol, (-)-α-pinene+ethanol for monitoring of bark beetles. Some bark beetles strongly attracted to (-)-α-pinene or (-)-α-pinene+ethanol. Some ambrosia beetles strongly attracted to ethanol. Our results indicated that (-)-α-pinene, ethanol, or (-)-α-pinene+ethanol could be useful infochemicals for the monitoring of bark beetles.
