| 摘 要： | 本文采用聚集度指标、Taylor幂法则、Iwao的m*-m回归分析法,对黑刺粉虱在4个茶树品种上的空间分布型进行了分析比较。结果表明:黑刺粉虱在茶树上空间分布均属聚集分布,个体间相互吸引,分布的基本成分是个体群,其聚集性随密度的增大而增加。经Blackith种群聚集均数测定,λ值均大于2,说明其聚集是由于害虫本身的群集行为与环境条件综合影响所致;方差分析表明,黑刺粉虱在树冠的中、下层叶片上分布显著多于上层叶片,在蜀永307上的分布数量显著多于福鼎大白茶、早白尖5号,南江1号上分布数最少,说明不同茶树品种对黑刺粉虱的抗性存在差异。

| Abstract: | The spatial distribution patterns of Aleurocanthus spiniferus in Four Tea Species were analyzed by five aggregation indices,Taylor's power law and Iwao's m-m regression analysis.The results showed that the spatial distribution pattern of Aleurocanthus spiniferus all belonged to aggregated distribution with the form of colony,which means they attract each other,and the basic component of the distribution was individual colony,and the aggregation intensity increased with increasing density.The aggregation cau... |
