摘要

Monthly light-trap surveys were conducted at Meifeng, Nantou county, Taiwan in 1990 and 1991. A total of 200 species of macroheteroceran species are recorded, most of which are in the families of Geometridae and Noctuidae. Species-abundance relations are examined and several diversity indeces are calculated. The relative abundance of trapped moth species fits a log-normal model, which indicates that the moth community in this habitat is in stable equilibrium. There is a significant relationship between numbers of moth and such climatic factors as temperature, and rainfall. Observed values of environmental variables can be used to predict species abundance. The possibility of using macroheteroceran species for ecological monitoring is discussed.

於1990及1991年間利用燈光誘集的方法在臺灣中部南投縣梅峰定期調查研究蛾類昆蟲相，兩年共採得200種大型蛾類，其中以尺蠖蛾及夜蛾佔最多數。採討物種豐度關係及計算幾種多樣性指數各種蛾類之豐度分布適合對數常態分布，蛾類昆蟲群聚在溫帶森林生態系中呈高度的平衡狀態。採集的蛾類昆蟲數與氣候因子特別是溫度與雨量最有顯著的相關性。本文附上樣區附近的植物相及各種蛾類昆蟲幼蟲之可能的食料植物提供參考並討論利用蛾類昆蟲做為生態監測的可能性。
