莫干山竹林蜘蛛的研究

莫干山位于浙江省德清县西北部,属天目山支脉。它由塔山、中华山、荫山、金家山、炮台山等组成,其中以塔山最高,海拔为719m,中心区位于北纬30°36′,东经119°52′。山上有毛竹、花竹、淡竹、刚竹、紫竹、早竹、苦竹、箬竹等20余种竹子。1983—1985年间,莫干山毛竹Phyllostachys pubescens遭受卵园蝽Hippota dorsalis的严重危害,死竹达32000余株。常年又受到竹笋夜蛾Oligia vulgaris竹织野螟Algedonia coclesalis竹虎天牛Chlorophorus annularis、竹红天牛Purpuricenus temminckii等危害,毛竹的产量、质量受到严重影响,自然景观遭到不同程度的破坏。蜘蛛为农林害虫的重要捕食性天敌,对害虫起着一定的控制作用。

A PRELIMINARY STUDY ON SPIDERS FROM BAMBOO FOREST OF MOGAN MOUNTAIN

In 1985-1989 the author collected about a thousand of spider specimens from bamboo forest of Mogan Mountain in Zhejiang Province. A tatol of 105 species belonging to 26 families, 74 genera were identified, in which the anyphaenidae is the first record from China. Stratification of the spiders in bamboo forest shows remarkable differences.All the spiders control to a certain extent pests such as bug(Hippota dorsalis), aphid, mosquito, fly, etc. The number of spiders and their species are higher in bamboo-tree mixed forest than those in pure bamboo forest.
