| 摘 要： | 本文应用多种方法测定了杨梅防火林带小卷蛾幼虫的空间分布格局．结果表明：小卷蛾幼虫符合负二项分布，分布的基本成份是稀疏的个体群，幼虫在林带内以聚集型扩散．根据Ｉｗａｏ法计算了在不同虫口密度下的林带间调查的最适抽样数 |
| 关 键 词： | 小卷蛾 空间格局 聚集度指标 回归模型群 |

| Abstract: | Several methods were used to measure the spatial distribution pattern for the larva of Olethreutinae spp in Myrica rubra Sieb et Zucc plantation in Fijian Province The results showed that the larva obeyed Negative Binomial distribution, and which basic component of spatial distribution is loose colony,the aggregated distribution would diffuse continually The optimal sampling number was calculated by Iwao 's method |
| Keywords: | Olethreutinal spp spatial distribution aggregation index regressive models |
