| 摘 要： | 白杨透翅蛾空间分布型可用一些聚集度指标测量,或用频率分布拟合,它的幼虫频率分布适合负二项分布,且同时适合Neyman—A型分布,用聚集度指标来检验,它的分布是聚集型的。 Iwao的回归和Taylor幂法则方法也是检验聚集型分布的好方法,检验的结果都说明白杨透翅蛾幼虫空间分布是聚集型的。 在上述分析的基础上,编制了序贯抽样分析表,可应用于白杨透翅蛾的幼虫防治效果的检验和虫害发生量的调查。

| Abstract: | The spatial distribution pattern of the larvae of Paranthrene abaniformis .Rotteribery ( Lepidoptera, Aegerildae ) was described twith several indexes of aggregation, orimitated by frequency distribution. The frequency distribution of the larvae fits to the negative binomial distribution and the Neyman-A distribution. The testing with several indexes of aggregation indicated that the distribution obeys aggregiaton battern.Iwao's regression method and Taylor's method of power function are good methods for detecting the aggregation pattern. The results showed that the spatial distribution of lavare obeys aggregation pattern too.According to the analysis the statistical tables of sequential sampling analysis 'were compiled which can be applied for testing the effect of elimination of pests. |
