| 摘 要： | 广州小斑螟Oligochroa cantonella Caradja是红树林的灾害性害虫之一。为了研究该虫在广西白骨壤林内的空间分布情况,在广西合浦县山口镇白骨壤林对该幼虫进行了调查研究,应用扩散系数(C)等6种指标分析,确定了该虫在白骨壤林中空间分布型为聚集分布。在此基础上,给出了不同虫口密度以及不同误差要求的最适抽样数。

| Abstract: | Oligochroa cantonella Caradja was one of the main pests attacking mangrove.Indices such as diffusion coefficient(C),mean crowding(m*) were used to analyze the spatial distribution of Oligochroa cantonella Caradja.The results showed that its spatial distribution pattern was assembly distribution.The optimum sampling numbers according to diffrent population densities and errors were given. |
