| 摘 要： | 本文采用聚集度指标法测定了木毒蛾(Lymantria xylina Swinhoe)卵、幼虫、蛹的空间格局。测定结果表明:木毒蛾卵块、幼虫和蛹在木麻黄防护林中呈聚集分布,分布的基本成分是个体群,幼虫在林内以聚集型扩散。应用Iwao方法,计算了在不同虫口密度下的林间最适抽样数,分析了中幼林中幼虫的序贯抽样。

| Abstract: | Spatial distribution patterns for egg-masses , larvae and pupae of Lymantria xylina Swinhoe have been measured by means of several indexes of aggregation in Fujian Province. The results show that the spatial distribution patterns of egg-masses, larvae and pupae are of an aggregation distribution in the forest of Casuarina sp., and that the basic component of spatial distribution pattern is loose colony. By Iwao's methods the optimal sampling size is determined, and the sequential analysis is also made. |
