摘  要：
2005年7~9月在四川省二郎山区域选择不同的海拔区域(1400~2300 m2、300~2600 m、2600~3100 m和3100~3400 m)和微生境(草堆、森林铺垫物、粪便、真菌、腐肉和腐木)进行隐翅虫资源调查,共设置样地72块,收集各海拔区域和各微生境内隐翅虫的物种组成和数量数据。结果表明:共获隐翅虫标本2389号,分属12个亚科,75个属,206个种。从个体数量上来看,前角隐翅虫亚科个体数最多,占48.35%,隐翅虫亚科次之,占14.48%;在物种数量上表现出同样的趋势,前角隐翅虫亚科物种数最多,占28.64%;隐翅虫次之,占16.99%,它们为该地区隐翅虫的优势类群;在个体数量上,胸片隐翅虫亚科、毒隐翅虫亚科、异形隐翅虫亚科、尖腹隐翅虫亚科、大眼隐翅虫亚科、筒隐翅虫亚科、和四眼隐翅虫亚科所占比例均在1%以上,它们为该地区的常见类群。总体上,隐翅虫个体数和物种数随海拔的升高呈现逐渐减少的趋势,在微生境选择上,草堆和森林铺垫物内隐翅虫个体数和物种数均明显多于其他几种微生境。

摘  要：
72 plots were designed to investigate the composition and number of Staphylinid beetles on different elevation gradient(including 1400~2300 m,2300~2600 m,2600~3100 m and 3100~3400 m) and microhabitats(including grass pile,forest litter,dung,epiphyte,carrion and decaying wood) of Erlang mountain in Sichuan province from July to September in 2005.The results showed that: 2389 specimens of Staphylinid beetle,including 12 subfamilies,75 genus and 206 species,were captured.Of these beetles,for the proportion of individual number in specimens,Aleochorinae was the highest and accounted for 48.35%,and followed by Staphylininae and accounted for 14.48%;similarly,for the proportion of species in specimens,Aleochorinae and Staphylininae accounted for 28.64% and 16.99%,respectively,and both of them could be considered as dominant groups of Staphylinid beetle in the study area.The number of other subfamilies like Xantholininae,Paederinae,Oxytelinae,Tachyporinae,Steninae,Osoriinae and Omaliinae each took more than 1% of the total,and they were considered as common-occurring groups in the study area.Generally,the species and individual number of Staphylininae were gradually decreased with the increment of elevation,and more Staphylinid beetles were captured in grass piles and forest litter than in other microhabitats.
