摘　　要：采用平行跳跃取样法对设施桃树上的桑白蚧发生危害及空间分布进行了调查。结果表明:桃树品种对雌雄虫的发生有不同的影响,蟠桃园的雌蚧虫数量显著多于油桃园,而雄蚧虫在二者间则没有差异;蚧虫在空间上有聚集分布的趋势,但在枝条或树干上的分布没有显著差异。The occurrence,spatial distribution and spatial distribution of P. pentagonaon on peach trees in greenhouse were investigated using parallel jump sampling method. The results showed that there was different damage among the peach species by P. pentagonaon,and the number of female adults on fiat peach orchard were significantly more than nectarine orchard, but there was no difference in number of male adults in both orchards;the population of the pests had a trend of aggregation in spatial distribution on peach trees in greenhouse, but no significant difference of damage was found between branches and bole.
