| 摘 要： | 2004年3–4月对西双版纳自然保护区季节性雨林、山地雨林、半常绿季雨林、落叶季雨林、石灰岩山季雨林、季风常绿阔叶林、暖温性落叶阔叶林、暖热性松林、热性竹林等9种植被亚型中象甲科昆虫多样性进行了研究。运用震落法采集标本853号,隶属于18亚科52属96种。跳象亚科个体数量最多,隐喙象亚科种类最丰富。季节性雨林和半常绿季雨林中不仅物种数最丰富,狭适种和稀有种也最多。暖温性落叶阔叶林及季节性雨林个体数量最丰富,落叶季雨林及半常绿季雨林最贫乏。9种植被亚型中象甲群落极不相似。季节性雨林和半常绿季雨林在生物多样性保护上具有重要地位,应予以优先考虑。

| Abstract: | We studied the species diversity of Curculionidae in seasonal rain forest,mountain rain forest,semi-evergreen monsoon forest,deciduous monsoon forest,karst monsoon forest,monsoon evergreen broad-leaf forest,warm deciduous broad-leaf forest,warm pine forest, and hot bamboo forest in Xishuangbanna Nature Reserve, Yunnan. A total of 853 weevils were captured by shaking-off collection, be-longing to 96 species, 52 genera, and 18 subfamilies. Among the subfamilies, Cryptorrhychinae, Otior-rhynchinae, Rhynchaeninae, Tychiinae, Curculioninae, Barinae, and Conoderinae contributed more than five species. Cryptorrhychinae, the most abundant subfamily, was represented by 21 species occupying 21.9% of the total. Rhynchaeninae, Curculioninae, Cryptorrhychinae, Otiorrhynchinae, Anthonomnae, Conoderinae, Barinae, Tychiinae, and Cioninae were represented by more than 10 weevil individuals, of which Rhyn-chaeninae had 394,comprising 46.2% of the total number. The greatest densities of individuals occurred in the warm deciduous broad-leaf forest and the seasonal rain forest, while relatively less occurred in the de-ciduous monsoon forest and the semi-evergreen monsoon forest. Every weevil community in the nine vegeta-tion subtypes had its own stenoecious and rare species. Seasonal rain forest was the richest in stenoecious and rare species, while semi-evergreen monsoon forest ranked second. Considering species richness, seasonal rain forest was the richest, whereas warm deciduous broad-leaf forest was the poorest. The weevil communi-ties in the nine vegetation subtypes are very dissimilar. More attention should be paid to seasonal rain forest and semi-evergreen monsoon forest for their important roles in biodiversity conservation. |
