东疆部分地区寄生蜂资源的初步调查

本文通过对新疆东部部分地区寄生蜂资源进行初步调查,并应用生物多样性主要特性指数的分析方法,对不同地区采集到的5 705头标本进行多样性分析。东疆的寄生蜂资源主要集中在以姬小蜂科Eu loph idae、金小蜂科P terom a lidae、环腹瘿蜂科F ig itidae、茧蜂科B racon idae、蚜茧蜂科A ph id iidae、姬蜂科Ichneum on idae等为主的27科。结果表明:巴里坤山前草地的寄生蜂多样性指数最高,而在巴里坤农田的寄生蜂多样性指数最低;木垒山地草原的寄生蜂丰富度指数最高,而多样性指数则比较低;各地物种优势度相差不大。

Preliminary Investigation of Parasitic Wasps Resources from Eastern Regions of Xinjiang

This essay is the primary investigation of Parasitic wasps resources from eastern regions of Xinjiang,based on 5,705 specimens collected.According to our investigation,there were 27 families distributed in some eastern regions,and the analysis result of main biological diversity index shows that the major familes of Parasitic wasps from the east parts of Xinjiang are Pteromalidae,Figitidae,Braconidae,Aphidiidae,Ichneumonidae and so on.The results also showed the speices competitions were fierce,and the ecological balance was weak in Balikun mountainious lawn and desert of Qitai;Biodiversity index is the biggest in Jimusaer mound of mountain,and the Dominance index is lowest in Mulei mountainious grassland,where each species of the community keeped in the equilibrium state.
