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.
