Field Bioassay for Longhorn Pine Sawyer Beetle Monochamus alternatus (Coleoptera: Cerambycidae) in Korea Based on Aggregation Pheromone 2-(Undecyloxy)ethanol

국문 초록 (Abstract)

소나무재선충(Bursaphelenchus xylophilus)은 소나무재선충병을 유발하여 한국의 소나무 숲에 심각한 영향을 미치고 있다. 소나무재선충에 감염된 소나무는 일반적으로 훈증 또는 파쇄처리되지만 소나무재선충병 피해지역의 방제효과를 검증할 수 있는 효과적인 방법은 아직 없다. 본 연구에서는 소나무재선충병 방제효과 검증에 적합한 솔수염하늘소 집합페로몬의 농도를 알아보기 위해 2-(Undecyloxy)ethanol, 알파-피넨, 에탄올을 이용하여 경상북도 포항시의 소나무재선충병 피해지역에서 필드테스트를 시행하였다. 총 27마리의 솔수염하늘소가 유인되었으며 고농도(700 mg)의 집합페로몬을 사용한 트랩이 가장 효과적이었다. 집합페로몬 2-(Undecyloxy)ethanol은 솔수염하늘소 개체수 조사와 소나무재선충병 방제효과 검증에 사용할 수 있을 것으로 사료된다.

The pinewood nematode Bursaphelenchus xylophilus (Nematoda: Parasitaphelenchidae) poses a serious threat to pine forests in Europe and East Asia, leading to a debilitating pine wilt disease. Infected pine trees in Korea are generally fumigated or crushed to small wood chips after felling. Although pine wilt disease often recurs in pest management sites, there are no adequate means to monitor the effectiveness of pest control measures in those sites. Recently, a male-produced aggregation pheromone, 2-(undecyloxy)ethanol, was shown to be useful for attracting several Monochamus species, which are vectors for the pinewood nematodes. In this study, we investigated the abilities of 2-(undecyloxy)ethanol at three different doses (175, 350, and 700 mg), as well as host plant volatiles (α-pinene and ethanol), to attract M. alternatus (Coleoptera: Cerambycidae) at a pine forest in Pohang, Korea where infected pine trees had been cut down and fumigated. Twenty-seven M. alternatus were captured in cross-vane panel traps made of polyethylene terephthalate bottles and acrylic sheets. The results indicate that a high dose of 2-(undecyloxy)ethanol (700 mg per trap) is the most effective for attracting M. alternatus. The aggregation pheromone could be used to monitor the effectiveness of pest control measures as well as M. alternatus populations.
