摘　　要：对烟粉虱成虫在大叶女贞上的空间分布型进行研究的结果表明,烟粉虱成虫在大叶女贞上呈聚集分布,分布的基本成分是个体群,通过聚集均数λ说明环境条件和昆虫本身行为是引起聚集的两个主要因素,在大叶女贞上烟粉虱成虫的种群密度分布差异不显著。The spatial pattern of Bemisia tabaci adults on Ligustrum lucidum was studied. The results indicated that the pattern of Bemisia tabaci adults was aggregating and the basic component of distribution was colony. Factor causing aggregation was dicussed gathering average λ. Environmental factors and the aggregation nature of the insect were the main factors. The population density was little difference on Ligustrum lucidum.
