在烟株上对玛绢金龟（ Ｍａｌａｄｅｒａｓｐ．） 成虫的空间格局进行了测定。采用Ｔａｙｌｏｒ 幂法则、Ｉｗａｏ 聚集格局回归分析法和负二项概率模型来处理调查数据。结果显示： ３ 种方法的聚集指数（ｂ， β， ｋ） 都表明玛绢金龟在烟株上的空间格局为聚集分布， Ｔａｙｌｏｒ 幂法则拟合田间数据优于Ｉｗａｏ 聚集格局回归分析法。负二项概率模型系数ｋ 与样方平均数相独立， 表明公共ｋ （ｋｃ） 值的存在， 测定得知公共ｋｃ 值为０－６５２９。为进一步建立玛绢金龟序贯抽样方法提供了基础数据。
The spatial pattern of adults of Maladerasp. Was determined on tobacco plants. Taylor power law, Iwao aggregation pattern regression analysis and negative binomial probability model were used to process the survey data. The results showed that the clustering index (b, β, k) of the three methods all indicated that the spatial distribution of the Smilar chinensis was aggregated distribution, Taylor power law fitting field data was better than the Iwao aggregation pattern regression analysis. The negative binomial probability model coefficient k is independent of the quadrat average, indicating the existence of a public k (kc) value, which indicates that the public kc value is 0-6529. It provided the basic data for establishing the sequential sampling method of the sericulture.
