| 摘 要： | 应用频次分析法和聚集度指标法对微红梢斑螟在马尾松和火炬松林中的空间分布进行研究．微红梢斑螟在马尾松和火炬松林中的分布为聚集分布，主要是负二项分布．其聚集是某些环境作用所致，而不是微红梢斑螟本身的聚集习性．

| Abstract: | This paper deals with the spatial distribution patterns of the larvae of Diorycitria rubella in masson pine and loblolly pine using the frequency distribution analysis and aggregation indices.The results indicate that it was an aggregation distribution pattern,especially the negative binomical distribution.The aggregation distribution pattern of the larvae was not caused by their habit,but by some environmental factors. |
