赤水河流域蝴蝶种类及区系组成

Species and Faunal Composition of Butterflies in Chishui River Basin

【目的】为研究赤水河流域蝴蝶多样性及区系组成,在贵州省仁怀市、习水县和赤水市等赤水河流域用样线法调查采集蝴蝶标本,并进行区系组成分析。【结果】调查共采集鉴定蝴蝶标本119种,包括凤蝶科、粉蝶科、蛱蝶科、珍蝶科、环蝶科、眼蝶科和斑蝶科等10个科,表明赤水河流域蝴蝶种类十分丰富,调查中还发现了较为珍稀的枯叶蛱蝶。就种数而言,以蛱蝶科最多,有35种,占总数的29.41%,眼蝶科次之,有20种,占总数的16.81%,之后较多的是凤蝶科和粉蝶科,赤水河流域广泛分布碧凤蝶、美凤蝶、金凤蝶和巴黎翠凤蝶等大型观赏蝶类。区系分析结果表明,赤水河流域蝴蝶同时分布在华南区的有83种,占总种数的69.75%,同时分布在华北区的有63种,而同时在华中区、蒙新区和东北区的较少,同时分布在青藏区的最少,仅15种,占比12.61%。说明赤水河流域的蝴蝶种类与华南区和华北区具有较高的相似性,与青藏区和东北区差异较大。【意义】研究结果为赤水河流域物种多样性研究提供基础资料。

[Purposes]To clarify the butterfly diversity and the faunal composition in Chishui River Basin,the species of butterflies were collected in Chishui River Basin of Renhuai City,Xishui County and Chishui County,and the faunal composition was analyzed in the paper.[Findings]The results showed that 119 species of butterflies were collected and identified in the area,including 10 families of the family Papilio,Pieridae,Nymphalidae,Enterobiaceae,Rhododendron,Ophthalmidae,and Monarchidae,showing that the species of butterflies in Chishui River Basin was very rich,and a relatively rare dead leaf Nymphalidae was also found in the survey.Besides,35 species of Enterobiaceae,accounting for 29.41%of the total,and 20 species of Ophthalmidae,accounting for 16.81%,were found in the area,and large ornamental butterflies such as Achillides bianor Cramer,Papilio memnon Linnaeus,P.machaon Linnaeus and P.paris Linnaeus were widely distributed in Chishui River Basin.The faunal composition results showed that 83 species of butterflies in Chishui River Basin were also distributed in South China,with the proportion of 69.75%,and 63 species were also distributed in North China,but the species number also distributed in Central China,Mengxin District and Northeast China was less,and only 15 species were distributed in Qinghai-Tibet District,with the proportion of 12.61%.It showed that the butterfly species in Chishui River Basin had a high similarity with that in South China and North China,but was quite different from that in Qinghai-Tibet and Northeast China.[Significances]The above studies provided basic data for the butterfly diversity research in Chishui River Basin area.
