摘要: 利用生态位理论,对新疆塔城、伊犁两地区麦田的麦双尾蚜Diuraphis noxia (Mordvilko)、麦二叉蚜Shizaphis graminum (Rondani)、麦长管蚜Sitobion avenae (F.)和禾谷缢管蚜Rhopalosiphum padi (L.)等4种麦蚜生态位宽度和重叠度进行了估测和分析。在塔城麦田麦双尾蚜时间生态位宽度最大,麦双尾蚜和麦二叉蚜时间生态位重叠最大,竞争激烈。伊犁麦田禾谷缢管蚜时间生态位宽度最大,麦二叉蚜在空间生态位和时空二维生态位上均占有明显的优势,麦长管蚜和麦双尾蚜的时间生态位重叠最大,麦长管蚜和麦二叉蚜在空间生态位和时空生态位重叠最大。

Abstract: The niche breadth and overlap of the four wheat aphids, Diuraphis noxia (Mordvilko), Schizaphis graminum (Rondani.), Sitobion avenae (F.) and Rhopalosiphum padi (L.), were measured based on the survey data in Tacheng and Ili, Xinjiang Uygur Autonomous Region. D. noxia and R. padi occupied longest temporal niche in Tacheng and Ili wheat field respectively. S. graminum had the greatest spatial and tempo-spatial niche breadths in Ili. Temporal niche of D. noxia overlapped mostly with that of S. graminum in Tacheng. However, in Ili, S. avenae and D. noxia overlapped mostly in their temporal niches. S. avenae and S. graminum heavily overlapped in both spatial and tempo-spatial niches.
