摘要
用聚集度指标、Iwao法、Taylor法对茶园中的茶尺蠖与其天敌三突花蛛的空间分布格局进行了测定检验。结果表明,茶尺蠖与三突花蛛在茶园中都呈聚集分布,分布的基本成份为个体群,而且个体间相互吸引。茶尺蠖与其天敌三突花蛛在空间分布格局上一致,后者对前者有一定的空间追随关系。
Three methods of aggregated indices, Iwao＇ s way and power law of Taylor were used to test the spatial distribution pattern of Earopis oblique Prout and its natural enemy Misumenops tricusphtatus in tea garden. The results indicated that both of them were in the spatial pattern of aggregation distribution, with a group of individuals as a unit. The spatial distribution patterns of Ectropis oblique Prout and its natural enemy Misumenops tricuspidatus were consistent, and tile latter was spatially following the former.
