庐山蛾类区系研究

庐山,地处中亚热带北沿,北纬29.35°,东经115.59°,属亚热带东部季风区域。庐山襟江带湖,雨量充沛,植物种类繁多,种子植物有1800余种,隶属158科642属。因此,庐山蛾类也较丰富。笔者于1975年5月开始,对庐山蛾类进行了调查,共鉴定出蛾类455种。现将庐山蛾类区系报告如下。 区系分析 庐山蛾类已鉴定出32科340届455种。区系情况如表。 从表可以看出:

STUDY ON FAUNA OF THE MOTHS IN LUSHAN

This is first paper on the fauna of the moths in Lushan. I started investigate since May 1975, until 1982. Now identified 455 species moths belong to 32 families and 340 genera. 1. The form faunal: Oriental species: 152 species, 127 genera (33.42% of total). Palaearctic species: 79 species, 63 genera (17.36% of total). Oricntal-Palaearctic species: 187 species, 149 genera (41.09% of total). Oriental-Neotropic species : 2 species (0.44% of total). Oriental-Australian species : 9 species (1.9% of total). Palaearctic-Nesarctic species : 2 species (0.44% of total). World'specics : 24 species (5.27% of total). From mentioned analysis can get this view : On fauna Lushan's moths, Oricntalspccics and Oriental-Palaearctic species are maintay 74.5% of total, the emphasis is on the oriental-Palaearctic. Besides Palaearctic species, and Few Oriental Australian, Oriental-Neoarctic, Palaearctic-Nesarctic, World's species arc have. 2. Perpendicular distributed: From the foot of the mountain to elevation of 200-300m, the Oriental species are 9.09%, Oriental-Palaearctic species are 35.72%, Elevation of 500-600m. in the middle of the mountain: Oriental species are 35.91%, Palaearctic species are 12.27%, Oriental-Palaearctic species are 40.45%, World' species are 9.09%. Other species are 2.20%. From 1000m. elevation to the top of the mountain. Oriental species are 31.61%, Palaearctic species are 19.80%, Oriental-Palaearctic species are 41.11%, World' species are 5.31%, Other species are 2.08%. Perpendicular distributed showed: From the foot to the top of the mountain, follow height of elevation gradually add, Oriental species gradually reduce, Palaearctic species gradually add. the perpendicular distributed of the moths is relate to height of elevation.
