摘要: 本项研究根据昆虫的生境, 把沙坡头昆虫区系分为流沙区(S区), 沙地人工植被区(M区)和沙地农业改良利用区(A区)。S区以拟步甲科(Tenebrionidae)昆虫为优势种; M区以象甲科(Curculionidae)、螟蛾科(Pyralidae)、草蛉科(Chrysopidae)、和蝗科(Acridiidae)等多科昆虫为特征; A区以金龟甲科(Scarabaeidae)等多科农业昆虫为优势种。分析沙坡头昆虫区系组成, 灰斑古毒蛾(Orgyia ercae)有大发生现象, 但其寄主——花棒(Hedysarum scoparium)在人工植被演替过程中的地位已不重要, 所以沙坡头昆虫区系的指示作用表明, 控制花棒在人工植被中的发展就可以达到昆虫区系改造的目的。

Abstract: Based on habitats of insects in Shapotou area the insect fauna can be divided into three groups: Shifting sands area(S), artificial vegetation area(M), and agricultural reclamation area(A), Tennebri-onidae is predominant species in S area; Curculionidae, Pyralidae, Chrysopidae, and Acridiidae were predominant species in M ares;Scarabaeidae and other many families insects were chief species in A area, analysis of insects fauna showed that there were a swarm of Orgyia ercae occurred by chance in M area,these insect lived on Hedysarwm scoparium which is not impotant during the processes of artificial vegetation succession. Therefore, controlling the development of H. scopareum in artificial vegetation system could transform the insect fauna in Shapotou area.
