Abstract: The influence of contents in "Qinyou 2" rape under application of different rates of N, Pand Kfertilizers of Myzus persicae is studied, and nine mathmatical models are established. The results show that soluble carbohydrates, potassium and moisture contents in rape plants affect significantly the population dynamics of Myzus persicae. The combination of lower Nand Kand midium Pis disadvantageous to Myzus persicae population growth.
