乌牛早茶园蜡蝉类与其8种天敌空间关系的聚块样方方差分析

为了分析在不同聚块大小条件下,天敌对蜡蝉类Fulgoroidea空间上跟随关系的密切程度、聚集原因和聚集范围,为评价蜡蝉类的天敌优势种和确定样方大小提供科学依据,运用聚块样方方差分析法、灰色关联度法、空间聚集强度指数法、种群聚集均数法和ρ指数法对安徽省合肥市乌牛早茶园不同大小聚块条件下的蜡蝉类及其8种天敌进行分析。蜡蝉类与其8种天敌均方差峰值时聚块样方数的关联度分析结果表明:与蜡蝉类空间上跟随关系密切的前三位天敌依次是茶色新圆蛛Neoscona theisi(0.8010)、草间小黑蛛Erigonidium graminicolum(0.7617)和三突花蟹蛛Misumenops tricuspidatus(0.7613)。在聚块内基本样方数K为1、2、4、8时,随着聚块内基本样方数的增多,聚集分布格局时的扩散系数C不断增大,均匀和随机格局时扩散系数不断减小。聚块内基本样方数K为1、2、4、8时其相互之间的蜡蝉类及其天敌的空间分布聚集程度差异均不显著。蜡蝉类及其天敌的种群聚集均数λ多数情况均大于2,其聚集是该虫本身原因引起的,并且λ的绝对值随着聚块内基本样方数的增加而不断增大。用蜡蝉类不同大小聚块的ρ指数判断个体群聚集时的最小范围是聚块中有4个基本样方,即本文的16 m^2。为该虫抽样时确定样方大小提供了科学依据。聚块样方方差分析法是分析害虫与天敌空间关系的一种简便而又实用的方法。
