초록

이 연구의 목적은 전남 영광군 일대 불갑산에 서식하는 나방의 고도 및 계절에 따른 다양성을 알아보는 것이다. 2016년 2월부터 10월까지 자외선등 트랩을 사용하여 총 5회 조사를 실시하였다. 그 결과 나비목 곤충 17과 177종 911개체가 채집, 확인되었다. 출현한 종 수는 자나방과가 51종 282개체, 태극나방과 46종 248개체, 밤나방과 34종 219개체, 포충나방과가 11종 42개체, 갈고리나방과 10종 56개체 등으로 나타났다. 계절별로는 5월과 7월에 종 수 및 개체수가 최대값을 나타내는 M-자형 양상을 나타내었다. 이 조사에서 확인된 종 수와 개체수를 바탕으로 계산한 기대 종 수 Chao 1은 224~326종으로 나타났지만 예상치가 점근선에 도달하지 않아 더 많은 종이 분포할 것으로 예상된다. 조사지 중 천연기념물로 보호를 받고 있는 참식나무군락 주변의 경우 가장 높은 종 다양성을 나타내고 있으며 우점하는 나방의 식성은 참나무와 밀접한 관련을 갖는 것으로 확인되었다. 나방 출현시기는 환경변화와 밀접한 연관을 짓기 때문에 추후 이 지역에 대한 종합적이고 지속적인 연구가 지속되어야 할 것으로 생각한다.

This study investigates the spatial and temporal variations of moth diversity of Bulgapsan Mountain, Younggwang, Jeonnam. Moth collecting was carried out using a UV light trap at three different sites from February to October 2016 (5 times). A total of 177 moth species and 911 individuals in 17 families were identified. The family Geometridae (51 species and 282 individuals) was the most dominant in the numbers of species and individuals, followed by Erebidae (46 species, 248 individuals), Noctuidae (34 species, 219 individuals) and others. Seasonal change of the number of species and individuals showed a M-shaped pattern with May and July peaks. The Chao 1 estimated number of species using the observed species was 224~326 species, but the graph did not reach an asymptote. Among the surveyed sites, the Neolitsea sericea community showed the highest numbers of species and individuals.
