摘要
用两个矩阵描述了红圆蚧（Ａｏｎｉｄｉｅｌａａｕｒａｎｔｉ）一龄若虫的扩散格局，把柑桔树简化成中心辐射的枝条结构，利用红圆蚧自然种群生命表的资料，建立了红圆蚧群动态的矩阵模型．通过改变寄生率的水平，在计算机上模拟了１０年内红圆蚧的种群动态变化。
he present paper employed two types of dispersal matrix to describe the first instar nymphsz’ dispersal in intratwigs By simplifying a citrus tree into a tree of center-radiated structure of twigs we constructed a new model for dynamics of Aonidiella aurantii population and predicted the development of it within the period of 2～10 years,thus opened a new way for the forcasting and controling of Red Scale
