摘　　要：文章应用3种检验分布型的方法分别检验了白刺夜蛾的分布型,结果表明:白刺夜蛾卵、幼虫和蛹的空间分布型均呈聚集分布,分布的基本成分是个体群。应用Iwao模型中的参数估计了田间调查时的最适抽样数。kinds of methods were applied to test the pattern of spatial distribution of L eiometonon siyrides Stautinger. The result showed that the ovum,grub and pupa of L . syrideswere all rally distribution and basic composition was single warm.The mostsuitable sample number was estimated by the parameter in lwao model.
