| 摘 要： | 云斑天牛Batocera horsfieldi是我国南方杨树的重要蛀干害虫, 研究云斑天牛种群的空间格局和抽样技术, 可为该虫的危害调查与防治提供理论依据。应用Taylor的幂法则、Iwao m*-m回归分析法及6个聚集指标, 对云斑天牛种群的卵、幼虫、蛹或成虫的空间分布型和抽样技术进行了研究, 并做了影响因素分析。结果表明: 云斑天牛的卵、幼虫、蛹或成虫在杨树上均呈聚集分布, 分布的基本成分是个体群, 其聚集性随密度的增加而增大。运用Iwao m*-m回归中的两个参数α和β值, 计算出了在不同精度下以刻槽、排粪孔和羽化孔为防治指标时的理论抽样数据表及序贯抽样数据表，生产中可查阅使用。 |

| Abstract: | Batocera horsfieldi is an important poplar stem-borer in south China. Studies on spatial distribution pattern and sampling technique can provide theoretical base for the damage survey and control of B. horsfieldi in poplars. In the study, the spatial distribution pattern of egg, larva, pupa or adult of B. horsfieldi in poplars was analyzed with Taylor’s power law, Iwao’s distribution function, and six aggregation indexes. The results showed that the spatial distribution pattern of egg, larva, pupa or adult of B. horsfieldi in poplars was all aggregated, and the basic component of the distribution was individual colony, and the aggregation intensity was increased with population density. By using the parameters α and β in Iwao’s m*-m regression equation, the optimal and sequential sampling numbers when the oviposition incisions, frass holes and emergence holes were selected as control indexes were determined and can be applied in the field control. |
