云南南滚河自然保护区昆虫丰富度分析

为揭示南滚河自然保护区的昆虫多样性，采用样地调查法和文献研究法考察、分析该保护区的昆虫丰富度，合计记录12目，110科，604属，934种。在前人研究基础上新增记录1目，9科，127属，287种，显著丰富了蚁科、叶蝉科、蛱蝶科、白蚁科的物种。丰富度分析表明，在科级和属级阶元上丰富度依次为鳞翅目＞鞘翅目＞半翅目＞膜翅目；在种级阶元上丰富度依次为鳞翅目＞膜翅目＞鞘翅目＞半翅目。以往对南滚河自然保护区鳞翅目、鞘翅目、半翅目的研究比较全面，对双翅目、膜翅目、同翅目、直翅目、等翅目及其他小目的调查明显不足。与高黎贡山、文山、无量山自然保护区的昆虫考察结果相比较，南滚河自然保护区的昆虫丰富度最高。

Analysis of the Insect Richness in Nangun River Nature Reserve of Yunnan Province

In order to reveal insect diversity of Nangun River Nature Reserve,insect richness of the nature re-serve was surveyed and analyzed through sample-plot survey and literature investigation methods.Totally,934 spe-cies belonging to 604 genera,1 10 families,and 12 orders of Insecta were recognized.Besides,1 order,9 families, 127 genera,and 287 species are newly supplemented on the basis of former researchers.The species of Formici-dae,Cicadellidae,Nymphalidae,and Termitidae were significantly enriched.The results of families and genera richness analysis showed that Lepidoptera〉Coleoptera〉Hemiptera〉Hymenoptera.In species,Lepidoptera 〉Hy-menoptera〉Coleoptera〉Hemiptera.There were relatively sufficient researches on Lepidoptera,Coleoptera,and Hemiptera of the nature reserve in the past.In contrast,the investigations of Diptera,Hymenoptera,Homoptera, Orthoptera,Isoptera and other small orders were obviously insufficient.Comparing with insect expedition results of Gaoligong Mountain Nature Reserve,Wenshan Nature Reserve,and Wuliang Mountain Nature Reserve,the insect richness of Nangun River Nature Reserve is on the top of numerous nature reserves in Yunnan Province.
