摘　　要：云斑白条天牛在黄河三角洲地区严重危害白蜡树,本研究应用聚集指标法、Taylor幂法则、Iwao m*-m回归分析法,对危害白蜡云斑白条天牛种群卵、幼虫、成虫的空间分布型和抽样技术进行了研究。结果表明:危害白蜡云斑白条天牛种群的卵、幼虫、成虫均呈聚集分布,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,建立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公式及序贯抽样数公式,计算出了抽样调查时的理论抽样数据表及序贯抽样数据表,在生产实践中可根据实际需要查询表中数据确定调查样本数。Batocera lineolata is an important stem-borer, attacking ash trees in Yellow River Delta. In the paper, study on spatial distribution pattern and sampling technique of egg, larva, and adult of B. lineolata in ash trees was analyzed with aggregation indexes, Taylor＇ s power law, and Iwao＇ s distribution function. The results showed that the spatial distribution pattern of egg, larva, and adult of B. lineolata in ash trees were all aggregated, 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 formula, which the incisions, frass holes and emergence holes were control indexes, were established. The optimal and sequential sampling data table were calculated, and the data can be applied in the field control.
