摘要: 本文根据田间调查资料,用7种检验分布型的方法进行检定,得出苹果黄色叶螨的分布型呈聚集分布。聚集程度是卵>若螨>成螨。成、若螨是以松散个体群存在,卵是以紧密个体群存在。以各虫态平均密度横向看,中部显著高于其它方位。从纵向看,各方位都显示出若螨>卵>成螨的规律。

Abstract: The spatial distribution pattern of Apple yellow mite (Tetranychus sp.) was analyzed by seven aggregation indices. The results showed that the type of the distribution of the eggs、nymphs and adults was ageregated. The density was eggs nymphs and adults in proper order. Adults and nymphs lived in groups of individual looscly, eggs were laid densely. In the horizontal average density of these various stages of mites the middle part was evidenly higher than the other parts. In vertical average density, nymphs density were higher than the others and the eggs were higher than the adults.
