| 摘 要： | 应用Taylor的幂法则、Iwao m*-m回归分析法及6个聚集指标,对韭菜迟眼蕈蚊(Bradysia odoriphaga Yang et Zhang)幼虫的空间分布型和抽样技术进行研究,以期指导韭菜迟眼蕈蚊田间防治.结果表明,韭菜迟眼蕈蚊幼虫呈聚集分布,分布的基本成分是个体群,其聚集性随密度的增加而增大；可运用Iwao m*-m回归分析法中的两个参数α和β值确定在不同精度下的理论抽样数及序贯抽样数.

| Abstract: | The spatial distribution pattern and sampling technique of Bradysia odoriphaga Yang et Zhang larva were analyzed using Taylor’s power law,Iwao’s m*-m regression equation,and six aggregation indexes.The results showed that the spatial distribution pattern of Bradysia odoriphaga larva was aggregated,and the basic component of the distribution was individual colony whose aggregation intensity increased with density.Using the parameters α and β in Iwao’s m*-m regression equation,the optimal and sequential sampling numbers were determined. |
