Abstract

In this study, to grasp the current status of cone insects occurrence on Korean fir (Abies koreana) in Mt. Halla, 117 cones damaged by cone insects in three areas in Mt. Halla were collected and placed in growth chamber until adults emerged from the cones from August to October on 2019. And species and numbers of adults emerged from the cones were identified. Also proportion of cones damaged by cone insects was examined at four study plots in Mt. Halla. As a result, total 233, 101, and 4 adults of Dioryctria abietella (Denis & Schiffermüller), Cydia kamijoi Oku, and Scathophaga stercoraria (L.) were identified from 117 collected cones, respectively. The average number of emerged adults per cone was 1.99 for D. abietella and 0.86 for C. kamijoi. And the average damage rate of cone insects in four study plots of Mt. Halla ranged from 49.7-80.1 percent, with differences between regions. Also, our results show that positive correlation between the damage rate per tree and the number of cones per tree, and between number of emerged cone insects and the size of cones were found. It suggests that the cone insects prefer host trees with lots of cones per tree and with larger size of cones.

한라산 구상나무 군락지에서 구과 해충의 발생 현황을 파악하기 위하여 2019년 8-10월에 3개 지역의 4개 조사구에서 구과 117개를 수집하여 생육상에서 우화시킨 후 출현종과 개체수를 확인하였다. 지역별 구과 해충의 피해율 조사를 위해 4개 조사구에서 93그루 1,235개 구과의 구과해충 피해를 확인하였다. 조사 결과, 채집된 117개 구과에서 솔알락명나방 233개체, 구상애기잎말이나방 101개체, 똥파리 4개체가 확인되었다. 구과 당 평균 개체수는 솔알락명나방 1.99, 구상애기잎말이나방은 0.86개체로 솔알락명나방이 2배 이상 많은 것으로 나타났다. 그리고 한라산 4개 조사구 전체 구상나무 구과의 평균 피해율은 49.7에서 80.1%로 조사구별 차이를 보였다. 또한, 구과 피해율은 수목 당 구과 수가 많을수록, 피해 구과에서 우화하는 구과해충 수는 구과의 크기가 클수록 증가하는 것으로 나타나 본 연구에서 확인된 구과 해충은 수목 당 구과 수가 많으면서 상대적으로 큰 구과를 갖는 구상나무를 선호할 것으로 예상되었다.
