景宁望东垟高山湿地自然保护区和景宁大仰湖湿地群自然保护区昆虫多样性研究

Composition and Diversity of Insect in Wangdongyang Alpine Wetland Nature Reserve and Dayanghu Wetlands Nature Reserve

2017年8月—2019年7月,利用网捕法、马氏网诱捕法、灯诱诱集法等对景宁望东垟高山湿地自然保护区和景宁大仰湖湿地群自然保护区进行了昆虫资源调查,并分别从物种组成、属种多度和多样性等方面进行分析。结果表明,望东垟保护区和大仰湖保护区共有昆虫23目243科1385属2195种;优势类群鳞翅目Lepidoptera、鞘翅目Coleoptera、半翅目Hemiptera、双翅目Diptera和膜翅目Hymenoptera的种数分别占保护区昆虫总种数的44.51%、13.49%、12.26%、8.7%和6.74%;拥有天敌昆虫、药用昆虫、食用昆虫和观赏昆虫累计113科556种,占保护区昆虫总种数的25.3%;由优势类群的科属多度分析表明,2个保护区昆虫群落结构稳定;由物种多样性指数也表明,2个保护区昆虫的Shannon-Wiener多样性指数、Simpson优势度指数、Margalef丰富度指数变化趋势一致,多样性指数较高,群落稳定性好。以上研究结果为保护区的昆虫资源保护和利用提供了科学依据。

During August 2017 to July 2019,investigation of insect resources was conducted by different methods in Jingning Wangdongyang Alpine Wetland Nature Reserve and Dayanghu Provincial Wetlands Nature Reserve,Zhejiang province.The result demonstrated that there were 2195 species belonging to 1385 genera,243 families and 23 orders.The dominant orders Lepidoptera,Coleoptera,Hemiptera and Diptera,were accounted for 44.51%,13.49%,12.26%and 8.7%of the total species in nature reserves.The natural enemy insect,medicinal insect,edible insect and ornamental insect had 556 species of 113 families,accounting for 25.3%of the total species.The genera abundance of dominant families and genera were analysed,which suggested stable insect communities in this area.At the same time,community structures were expressed by Shannon-Wiener Index,Simpson Dominance Index,Margalef Species Richness Index and Pielou Evenness Index.The results revealed that Wangdongyang Nature Reserve and Dayanghu Nature Reserve have high insect diversity indices and stable community.
