| 摘 要： | 聚集度指标测定、Iwao's M~·,(?)线性回归和Taylor's幂的法则分析结果表明:豆田龟纹瓢虫的空间分布型为聚集型,其基本成分是个体群,且聚集度随种群密度增加而升高。聚集的原因是由环境条件引起的。由于属聚集分布,用Iwao's资料代换法求取每块田龟纹瓢虫的相应y值。根据Iwao's抽样公式和序贯抽样公式的计算结果,为大豆蚜虫的防治提供理论依据。

| Abstract: | The results obtained by measurement of the indices of aggregation intensity, analysis of Iwao' M' X regression and of Taylor's spower rules indicated that the spatial distribution pattern of Propylaea japomca Thunberg in soybean fields showed aggregation distribution and individual group. And it's aggregation degree increased with increase of population density. Aggregation was caused by environmental conditions. Because the distribution showed aggregation performance, the corresponding Y value of Propylaea Japomca Thuuberg in every fields was calculated by Iwao's data replacement method. The calculated results by Iwao's sampling formula and order sampling formula could be used as theoretical basis for prevention and control of soybean aphids. |
