The spatial,temporal and two-dimensional niche breadths and niche overlaps of Hyalopterus amygda/i, Myzus persicae and their main natural enemies were studied in this paper. The results showed that the synchronism and sympatry of the pests and their natural enemies Harmonia axyridis, Propylaea japonica and Chrysopa septempunctata were both higher, which provided a foundation for protecting and using natural enemies to control the two pests.Key words: Hyalopterus amygdali; Myzus persicae; Natural enemies; Ecological niche
