    烟粉虱卵在黄瓜上的空间分布及抽样技术

    Spatial Distribution Pattern and Sampling Technique of the Eggs of Bemisia tabaci on Cucumbers

    • 摘要: 对烟粉虱卵在黄瓜上的空间分布型进行了研究.结果为:Iwao回归模型α=1.148 2>0,β=1.423 1>1;Talor幂法则loga=0.398 4>0,b=1.517 4>1.表明烟粉虱卵呈聚集分布, 其聚集度随种群密度的升高而下降, 分布的基本成分是个体群, 个体间相互吸引.采用Iwao方法求出不同卵密度下的最适抽样数.
