摘要
通过网扫、黑光灯诱集、马氏网诱集等方式,对浙江凤阳山国家级自然保护区昆虫多样性进行了为期2 a的系统调查,共采集标本23 231号;结合文献记录,共发现凤阳山昆虫25目239科1 161属1 690种。通过对该区昆虫4个优势目鳞翅目Lepidoptera,鞘翅目Coleoptera,膜翅目Hymeuoptera和双翅目Diptera中科的属种多度进行的分析显示,各科昆虫结构主要以单种科、寡种科和单属科、寡属科组成,昆虫群落稳定性较好。利用Margalef物种丰富度指数(d),Simpson多样性指数(D),Shannon-Wiener多样性指数(H′)和Pielou均匀度指数(J′)进行的分析表明,该区昆虫物种丰富。提出应营造多样性的植物群落、减少人为干扰和加强对昆虫资源潜在价值的研发与利用,以对昆虫多样性进行保护。
23 231 insects were collected by the methods of net,light trap,malaise trap and etc.to conduct a two years＇ intensive survey on the diversity of insects from Fengyangshan Mountain in Zhejiang Province.Totally,1 690 species in 1 161 genera,239 families and 25 orders were found,including previous records.The four dominant orders（Lepidoptera,Coleoptera,Hymeuoptera and Diptera） were mostly composed of monotypic families,oligotypic families and mono-genus families,oligo-genus families,which suggested stable insect communities in this area.Community structures were expressed by Margalef＇s species richness index（d）,Shannon-Wiener＇s diversity index（H′）,Simpson＇s diversity index（D） and Pielou＇s species evenness（J′）.In order to protect insect resources in this area,it was suggested creating diversified plant communities,reducing human disturbance and strengthening the research,development and utilization of the potential values of insect resources.[Ch,3 fig.2 tab.14 ref.]
