湖南八大公山斗篷山林区鞘翅目多样性初步调查

Diversity of Coleoptera in Doupeng Forest Area of Badagongshan Nature Reserve in Hunan Province

为了解八大公山自然保护区鞘翅目昆虫的多样性,2021年7~8月,利用灯诱法结合网捕法对八大公山斗篷山地区鞘翅目昆虫进行调查,并分析了该地区的鞘翅目昆虫种类、区系分布以及多样性情况。结果表明:本次调查共采集标本1969份,共收集到鞘翅目昆虫种类104种,分别隶属于28科93属,其中新记录属7个,新记录种8种。区系分析表明该地区东洋种占优势,广布种次之,古北种最少,其所占比例分别为60.58%、34.61%、4.81%。而多样性分析则表明该地区鞘翅目昆虫群落稳定,在时间分布上7月的生物多样性普遍要高于8月。

To understand the diversity of Coleoptera in Badagongshan Nature Reserve,we investigated Coleoptera insects in the Doupeng Mountain area using light traps and net traps from July to August 2021.All the species collected were cataloged,and faunal composition,combined with species diversity were analyzed.The results showed that a total of 1969 specimens were collected in this survey,including 104 species of Coleoptera,belonging to 93 genera and 28 families,among which 7 genera and 8 species were newly recorded.The faunal analysis showed that oriental species were predominant,followed by widespread species,and Palaearctic species were the least,accounting for 60.58%,34.61%,and 4.81%,respectively.The diversity analysis indicated that the coleoptera insect community were stable in this area,and the biodiversity in July was higher than that in August.
