| 摘 要： | 用聚集度指标法和格局纹理分析,对李始叶螨活动螨(幼、若、成蟥)的空间格局进行了测定,结果表明,在各种密度水平下,该害螨在苹果树内的分布格局均呈聚集型,聚集度在低密度下最高,分布的基本成分是疏松的个体群,个体群的分布是聚集的,个体群内的分布是随机的.个体群大小约4～6片叶.

| Abstract: | Based on the analysis of the data obtained from a preliminary investigation,the comparative method of the Iwao method,the Taylor method and the aggregated index method were used to study the spatial pattern of E.pruai Orulenraas.The results showed that the distribution of the mobile mite was of an aggregate pattern.The mobile mite occur as loose colonies (mean size=4 to 6 leaves).Distribution of the colonies is aggregate and infra-colony distribution is obviously random. |
