摘要
选择南京市区典型杨树林样地,对蛾类昆虫群落结构和多样性进行分析。结果表明:南京市区杨树林蛾类14科60属63种,占南京市区蛾类总种数的12.6%;其中夜蛾科(Noctuidae)数量占有绝对优势(32.5%),其次是尺蛾科(Geometridae)(22.1%),夜蛾科、尺蛾科、螟蛾科(Pyralidae)、天蛾科(Sphingidae)及毒蛾科(Lymantriidae)5科个体数占总个体数的88.3%;优势种为掌尺蛾(Amraica superans)、畸夜蛾(Borsippa quadrilineata)、枥镰须夜蛾(Zanclognatha nemoralis)、斜纹夜蛾(Prodenia litura)和小地老虎(Agrotis ypsilon)等17种蛾类;各季节蛾类多样性指数趋势与均匀度指数、丰富度指数趋势一致,与优势度指数趋势相反。
Typical samples of poplars in the Nanjing area were selected to compare the moth community structure and diversity. The results showed that the moths in poplars of Nanjing belonged to 14 families, 60 genera and 63 species. Noctuidae was absolutely dominant in different families, occupying 32.5% of the total, followed by Geometridae, occupying 22.1%. The quantity of the five families of moths including Noctuidae, Geometridae, Pyralidae, Sphingidae and Lymantriidae accounted for 88.3% of the total. There were 17 dominant species including Amraica superans, Borsippa quadrilineata, Zanclognatha nemoralis, Prodenia litura and Agrotis ypsilon. The index of diversity was consistent to the indexes of evenness and richness in different seasons, but opposite to the index of dominance.
