摘  要：
崆峒山昆虫群落的组成及生物多样性调查研究结果表明:(1)崆峒山有昆虫16目,107科,466属,909种。鳞翅目、鞘翅目为优势目。有天敌昆虫9目、32科、70属、160种,其它种类昆虫与天敌昆虫之比为4.7∶1,天敌自然控制害虫的作用显著。还有一些具有经济、药用、食用、传粉、观赏价值的资源昆虫。鉴定出甘肃省记录种79种。(2)崆峒山昆虫丰富度指数变幅较大,种类和数量都占优势的鳞翅目丰富度指数最大,d=58.76;鞘翅目居第2位,丰富度指数d=30.26;丰富度指数的变幅为58.76;崆峒山昆虫的丰富度指数与优势度成正相关。

摘  要：
The research on insect communities and diversity in Kongtong Mountain was made in the paper.The results are: 1) There are 909 species insects,belonging to 16 orders,107 families,and 466 genera.Among them,there are 160 natural enemy insect species,belonging to 9 orders,32 families,70 genera.The other pest insects and natural enemy insects' proportion is 4.7∶1,and the control effect of natural enemy insects on pest insects is remarkable.The natural enemy insect species are 17.60% in the whole insect species.There are economical,medical,edible,pollination,ornamental insects in the mountains,and among them there are 79 species newly recorded in Gansu Province.Lepidoptera,Coleoptera are two majorities.2) Insects species diversity index is changeable all the time.Lepidoptera index is in the first position and its d=58.76.Coleoptera index is the second position and its d=30.26.The change range of diversity index is 58.76%.The species diversity index is positively correlated with the predominance degree of insect in Kongtong Mountain.
