臺大實驗林溪頭及鳳凰地區桑科植物鱗翅目昆蟲初探

鱗翅目（Lepidoptera）昆蟲廣泛分布於全世界，其物種多樣性占昆蟲網約15-20%，大部分種類為植食性昆蟲，為生態功能群中重要的營養循環因子。瞭解鱗翅目昆蟲相的組成，對研究森林生態系的營養循環與動態提供了很重要的基礎資料。本研究首次針對臺大實驗林所轄的溪頭自然教育園區及鳳凰自然教育園區內桑科（Moraceae）植物的鱗翅目昆蟲相進行調查且飼育，海拔範國約800m至1100m，自2013年2月起至12月止，發現利用桑科植物為幼蟲寄主之鱗翅目共計7科15種，包含蛺蝶科（Nymphalidae）3種，蠶蛾科（Bombycidae）4種，草螟科（Crambidae）1種，尺蛾科（Geometridae）2種，毒蛾科（Lymantriidae）1種，夜蛾科（Noctuidae）3種，榕蛾科（Phaudidae）1種。臺灣地區桑科植物多樣性以海拔500m以下最為豐富，並承載多樣性頗高的鱗翅目功能群，是研究生物多樣性的極佳材料，未來若能於實驗林全區域進行桑科鱗翅目功能群研究，將可發現更高的物種多樣性。本研究資料可做為生物多樣性研究及兩自然教育園區生態解說教育之參考資料。

Lepidoptera is widely distributed over the world that is accounting for 15-20% in Insecta in terms of diversity. Most of them are herbivores and play an important role to nutrient recycling in ecosystem. This investigation provides a fundamental data on nutrient recycling and dynamic of forest ecosystem to understand the Lepidoptera composition . Therefore this study focused on Lepidoptera investigation with larvae bred on Moraceae plants in Xitou and Fenghuang area and the elevation range from 800 to 1100 meters during February to December 2013 in the Experimental Forest, National Taiwan University. The results showed that fifteen species belonging to seven families of Lepidoptera are recorded including three Nymphalidae species, four Bombycidae species, one Crambidae species, two Geomeridae, one Lymantriidae species, three Noctuidae species, and one Phaudidae species. The data could use as reference for biodiversity study and environmental education in Xitou and Fenghuang natural education area. Considering Taiwan has rich Moraceae plants below the elevation of 500 meters, which in turn carries great diversity of Lepidoptera. This research theme could anticipate higher species diversity of full-region survey in the near future.
