系统调查了油菜不同时期各叶位的蚜量，求得各时期的时间生态位宽度、空间生态位宽度及时间—空间二维生态位宽度，并加以分析比较。
The numbers of Myzus persicae in all leaves of rape plants in different developmental periods were investigated and the indexes of three ecological niche breadthes e.g.time,space and time-space were obtained,compared and analyzed in this paper.
