| 摘 要： | 对荔龟背天牛幼虫于荔枝园中的空间分状况调查和分析，表明该虫的空间分布为负二项分布；空间图式是聚集型；分布的基本成分为疏松的个体群。聚集行为受环境因素（主要是荔枝品种）的影响，此外，利用分布型参数确定了龟背天牛的理论抽样数并建立了序贯抽样检定表。

| Abstract: | Various methods were used to determine the spatial distribution patterns of Aristobia testudo larvae in lichi orchards. The . results showed that the spatial distribution of the larvae conformed to negative binomial distribution and the spatial pattern was aggregative. Basic distribution component of population distribution was loose individual groups. The cause of aggregative distribution seemed to be due to some environmental factors such as the strains of lichi. The theoretical sampling numbers were estimated in different population densities with different estimated errors and confidence limits. Iwao's sequential sampling was established with Iwao's regression equation. |
