| Abstract: | The spatial distribution pattern of Myzus persicae Sulzer was determined by the application of index of aggregation,Iwao's Law,Taylor's Law.All the results showed that its spatial distribution pattern was characterized by aggregated distribution,and the fundamental constituent of distribution was individual population.The cause of aggregation was the condition of environment. |

| Keywords: | Myzus persicae(Sulzer) spatial distribution index of aggregation |
