摘 要：
在西双版纳热带雨林中的木瓜榕和对叶榕两个种群内共采集昆虫标本 2 0 0 88号 ,其中访问木瓜榕的昆虫有 8目 2 1科 33属 ,共 4 0种 ,在对叶榕上采集到 37种昆虫 ,隶属于 7目 2 1科 32属。两种榕树的昆虫群落组成特点表现为 :害虫种类多 ,种类达群落总种数的 94 6 %～ 97 0 % ,但个体数量少 ,主要是鳞翅目、鞘翅目及同翅目等类群的昆虫 ;许多昆虫既喜食榕果又可危害叶片 ,部分种类仅取食叶片和蛀干 ;这些类群中在隐头花果内外活动的昆虫种类最多 ,达 5 4% ,数量上占到 93 1%～ 94 3%。益虫种类少 ,则个体数量多 ,尤其是传粉榕小蜂种群数量占绝对优势 (86 4 %～ 90 2 % ) ,它的成功传粉影响着榕树群落的构建和稳定

摘 要：
Ficus auriculata Lour and Ficus hispida Linn are important plant species in the tropical rainforest They provide foods and habitats for insects, birds and so on 20 088 samples of insects have been collected, including 8 orders, 21 families, 33 genera and 39 species on the F auriculata and 7 orders, 21 families, 32 genera and 37 species on the F hispida Common characteristics of insect communities show that pests species is abundant, the ratio is 94 6% 97 0%, but amount per species are limited and they belong mainly too Lepidoptera, Coleoptera and Homopyera etc Some insects not only eat fig fruits but also eat leaves, other eat leaves or branches In these insect communities, insects species are the most on the syconia, the ratio is about 54%, and amount is 93 1% 94 3% On the contrary, though species of beneficial insects are low, they have huge individual quantities The amount of pollination fig wasp is 86 4% 90 2% of all insects, and its successful pollination influences stability and development of fig trees communities
