海南岛粉蝶的区系及其生态分布的研究

A Study On the Fauna and Ecologic Distribution of White in Hainan Island

１９８９～１９９１年，在海南岛收集到粉蝶３５种，加上文献记载的２种共３７种，它们隶属于１３个属，大多是典型的东洋区种类（占６７．５７％）。这些粉蝶多分布于植物种类较丰富的热带山地雨林、热带常绿季雨林和热带半落叶季雨林中。在热带山地雨林中收集到粉蝶３１种，占总种数的８３．７８％。亚洲热带区域的特有种有１０种，热带山地雨林中就有９种分布。每年４～６月为多数粉蝶的盛发期．

Hainan Island is situated in the southwest of Guangdong Province,and thenorth of South Sea(18°09′～29°11′N and 108°37′～111°04′E).It is the second big Island ofabout 33 600 square kilometres and largest tropical district in China. In the Island there areseveral forest vegetation types,abundant fauna and many plant species. There are 37 speciesof white in Hainan Island,of which 35 species have been collected by us and the other 2species are estimated from other publications. The 37 species come from 13 genera. Many ofthem are typical species of Orient Region. 67.57 percent of the white are distributed in Ori-ent Region. Most of the white species are distributed in tropical semi-deciduous monsoonforest,tropical evergreen monsoon forest and tropical mountain rain forest. In tropical, mountain rain forest,species of living beings are abundant,31 species of white have beencollected,accounting for 83.78% of the total. 10 species of them are peculiar species inAsian tropical district,9 species of them are distributed in tropical mountain rain forest. Thetopmost appearance period of many white species are found in April～June every year.
