| 摘 要： | 本文以5种测定方法、6个聚集指标对山楂红蜘蛛的空间分布型进行了测定。结果表明:该害蟎是以疏松的个体群形式呈聚集分布,个体群内个体的分布是随机的;引起该害蟎聚集的主要因素是环境的异质性,而与本身的聚集行为无关。

| Abstract: | Based on the analysis of the data obtained from a preliminary
investigation, the comparative method of frenquency distribution,
the Iwao methed, the Taylor method and the aggregated index
method were used to test the spatial distribution pattern of hawthorn
red mites (Tetranychus crataegi Hirst). The results showed that the
pest was distributed aggregately in a loose individual community and
individuals in the community were distributed random. The different
characters of environment were the principal factor influencing the
aggregative habits of the pest. |
