| 摘 要： | 本文通过对新菠萝灰粉蚧的雌成虫进行田间调查，应用David和Moore的聚集性指标、Cassie的指标C和Kuno的指标CA、Lloyd的平均拥挤度m*及聚块性指标m*/m 3个聚集性指标及Taylor的幂法则和Iwao的m* m的回归法对新菠萝灰粉蚧雌成虫的空间分布型进行了分析和检验。结果表明，其在剑麻株内的空间分布为聚集分布，且具有密度依赖性，引起聚集的原因主要是新菠萝灰粉蚧雌成虫自身习性，与环境因素也有一定关系。

| Abstract: | The spatial distribution pattern of the larvae of Dysmicoccus neobrevipes (Beardsley) female adults was studied by 3 aggregation indices and regressional analysis. The results showed that the spatial distribution pattern of the larvae was aggregated distribution in individual plants of the sisal, and density dependent. The aggregation of the populations of this insect was due to their behavior and some environmental factors. |
