| 摘 要： | 研究了小麦生长中后期麦长管蚜和禾谷缢管蚜的垂直分布及生态位,结果表明,2种麦蚜在麦田混合发生,种群动态相似,主要分布于小麦穗部和中上部叶片,时间生态位和空间生态位宽度值接近,生态位相似性比例分别高达0.8513和0.8418,禾谷缢管蚜的空间生态位重叠值大于麦长管蚜,麦长管蚜的时间生态位重叠值大于禾谷缢管蚜。

| Abstract: | The vertical distribution and niche of two species of aphids in the late-mid period of wheat were studied.The results showed that both Macrosiphum avenae and Rhopalosiphum padi did damage to wheat in the same period,which had similar population dynamic,mainly distributed in the ears and upper-mid leaves,possessed near time and spatial niche breadth with the similarity of 0.8513 and 0.8418,respectively.The spatial niche overlap of Rhopalosiphum padi was bigger than that of Macrosiphum avenae,but time niche overlap of Macrosiphum avenae was bigger than that of Rhopalosiphum padi. |
