| 摘 要： | 研究惠东黄蚜小蜂的方位动态,结果表明:在马尾松林中的不同坡位上、树冠不同方位上其平均密度差异不显著;在树冠的不同层次上其平均密度差异显著,主要表现为下层>中层>上层.应用聚集度指标法和回归分析法测定惠东黄蚜小蜂空间分布特征,结果表明:12块标准地惠东黄蚜小蜂聚集度指标均服从聚集分布.Iwao和Taylor幂法则回归方程分别为:M·=1.1447-x+1.7983和S2=2.90681-0.8501x,两个方程的相关系数较高,表明惠东黄蚜小蜂的种群分布在一切密度下都是聚集的,分布的基本成分是疏松的个体群,这种种群聚集与其寄主害虫松突圆蚧的空间分布特征有关.最后列出其最适抽样数和序贯抽样方案.

| Abstract: | The spatial distribution of Aphytis huidongensis population was different on different orientation of pine forest.The average density was the highest in lowest crown of pine trees,and there was no distinct difference among different slope position and crown orientation of pine trees.The methods of comparative frequency distribution were employed to measure the spatial distribution pattern of parasitoids of A.huidongensis in pine forest.The spatial distribution pattern were measured by the indexes of aggrega... |
