根据贵州不同地区８个柑桔园的１６组资料，用最近邻体法测定了黑刺粉虱［Ａｌｅｕｒｏｃａｎｔｈｕｓｓｐｉｎｉｆｅｒｕｓ（Ｑｕａｉｎｔａｎｃｅ）种群在柑桔叶片上的分布，测定结果均为聚集分布。
Based on the data of measurement of the citrus leaves with citrus spiny [Aleurocanthus spiniferus (Quanitance)] taken from 8 citrus orchards of the different districts in Guizhou Province,using the nearest neighbour method, the distribution pattern of leaf surface of cirtrus spiny blackfly on the citrus leaves was calculated .
