浙江九龙山国家级自然保护区昆虫群落结构及区系特征分析

Analysis of Insect Community Structure and Faunal Characteristics in Zhejiang Jiulongshan National Nature Reserve

为了解浙江九龙山国家级自然保护区昆虫的群落结构及区系特征,于2017—2021年在保护区采用网捕法、马氏网诱集法、灯诱等方法对昆虫野生资源进行了野外调查。结果表明:保护区已知昆虫共有21目217科1387属2253种,其中优势类群为鳞翅目、半翅目、鞘翅目、膜翅目和双翅目;在众多优势昆虫类群中,鳞翅目主要科的物种丰富度较高;优势类群的属种多度分析表明,该区域昆虫的群落结构比较稳定;区内昆虫各目的区系组成差异较大,其中中国特有种成分所占比例相对较高,占比63.65%,表明分布昆虫的特有性和古老性;同时,拥有天敌昆虫、食用昆虫、观赏昆虫和药用昆虫共计128科705种,占保护区昆虫总种数的31.29%。研究结果可为保护区内昆虫资源的科学保护和合理利用提供数据支持。

In order to understand the community structure and faunal characteristics of insects in Zhejiang Jiulongshan National Nature Reserve,a field survey of insect wild resources was carried out in Jiulongshan National Nature Reserve from 2017 to 2021 by means of net trapping,Mahalowitz net trapping and lamp trapping.The results showed that there are 2253 species of insects known in the nature reserve,belong to 21 orders,217 families,1387 genera.Among them,the dominant orders were Lepidoptera,Hemiptera,Coleoptera,Hymenoptera,and Diptera.Among the many dominant insect groups,the species richness of the major families of Lepidoptera was higher than others.The analysis of genus and species abundance of dominant groups showed that the insect community structure in this region was relatively stable.The floristic composition of different insect orders in this area was quite different,among which the proportion of Chinese endemic species was relatively high,accounting for 63.65%,indicating the endemic and ancient nature of insects distributed in this region.In addition,there are 705 species of natural enemy insects,edible insects,ornamental insects,and medicinal insects in 128 families,accounting for 31.29%of the total number of insect species in the reserve.The research results can provide data support for the scientific protection and rational utilization of insect resources in the reserve.
