국내 전역에 분포되어 있는 잣나무(Pinus koraiensis)에 소나무재선충(Bursaphelenchus xylophilus)을 옮기는 새로운 매개충으로 북방수염하늘소(Monochamus saltuarius)에 의한 발병이 보고되면서 소나무재선충의 빠른 확산이 우려되고 있다. 잣나무의 주요 성분이며 Monochamus속에 유인성분으로 보고된 $alpha$-pinene과 에탄올, 나무종류의 유인성분으로 알려진 Ips 속 페로몬(ipsenol, ipsdienol)에 대하여 혼합 유인효과를 검토한 결과, ipsenol + ipsdienol에서 67.9%, 그리고 ipsenol과 ipsdienol을 $alpha$-pinene + 에탄올과 혼합 처리 시 각각 67.7%, 79.3%의 유인력을 보였다. 특히 ipsenol에 비해 ipsdienol의 $alpha$-pinene + 에탄올에 대한 혼합효과가 높았으며, 북방수염하늘소의 수컷에 비해 암컷이 높은 유인력을 나타냈다.
The pine sawyer, Monochamus saltuarius Gebler (Colepotera: Cerambycidae) was newly known as a vector of pinewood nematode causing the pine wilt disease in Korean white pine (P. koraiensis Siebold & Zucc.) forestry. Recently, it has a serious problem to spread fast and widely throughout Korea by transferring M. saltuarius. For the control of M. saltuarius, this study was investigated the attractants by analyzing from the Korean white pine. Major components of Korean white pine was analyzed as $alpha$-pinene and ethanol, and reported as an attractant against Monochamus genus. Ipsenol and ipsdienol, the pheromones of Ips genus known as attractant components of woodboring beetles, were tested to the attractive efficacy against Monochamus saltuarius. The attractive efficacy showed 67.9% of Ipsenol plus ipsdienol and ipsenol, ipsdienol mixed with $alpha$-pinene plus ethanol was showed 67.7% and 79.3%, respectively. Especially, ipsdienol with $alpha$-pinene and ethanol was shown the high synergy effect, and the attractant effect was higher at M. saltuarius female than male.
