摘　　要：运用聚集度指标法、Iwao法、Taylor法测定了桃蚜的空间分布型,结果表明:桃蚜的空间格局为聚集分布,分布的基本成份为个体群.聚集的原因是由于环境条件引起的.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.
