| 摘 要： | 研究了春白菜田小菜蛾幼虫空间分布型及其抽样技术.通过频聚集度指数的测定、M＊-M回归和Taylor幂法则分析,结果表明,小菜蛾在春白菜上为聚集分布,空间分布的基本成分是个体群,个体间相互吸引,应用Blackith的种群聚集均数检验了聚集的原因.根据Iwao抽样公式,获得了在各种密度下的最适抽样数,建立了序贯抽样模型.

| Abstract: | The paper deals with the spatial distribution and sampling technique of spring Chinese cab bage Plutella xylostella L. Ag indicates Plutella xylostella L gregation indices and IS in individual colony, and the individual the aggregation s of Plutella xyl the methods of Iwao and Taylor are used. The pattern, the basic element for the distribution ostella L attracts each other,and the individual result is an colonies is also attracted. The theoretical sampling number of Plutella xylostella L in the field, and sequential sampling model is established by Iwao method. The sequency sampling procedure is based on. |
