| 摘 要： | 杨十斑吉丁虫空间分布型可用频次分布拟合或用一些聚集度指标来度量。它的幼虫频次分布符合负二项分布,用聚集度指标度量适合聚集型分布。Iwao回归与Taylor幂法则也是确定聚集型分布的好方法,结果都说明是聚集型的。以此可以确定抽样调查的最适抽样数,编制序贵抽样分析表,用于防治效果的检验与危害程度的分级。

| Abstract: | The spacial distribution pattern of larvae of Melanophila decastigma Fabri-cius is negative binomial distribution fitted by the fiequency distri bution , and is aggregation distribution fitted by means of several indexes of aggr- egation Iwao's method of regression of mean crowing (X) on mean density (X) and Taylor's power method of mean variance (s2) on mean density (X;) are good methods for detecting the aggregation pattern. All of them show that the spacial distribution pattern is aggregation distribution, so it is eazy to determine the optimum sampling size and to compile the tables of sequential simpjing analysis for testing the effect of pest control and classifying the harmed level by pests. |
