摘　　要：在保定市对园林植物上5种蚧虫寄主的选择以及在资源利用上的空间和营养生态位进行了研究。结果表明:5种蚧虫在不同的空间资源类型分布广,对寄主植物选择有偏好性,碧桃、紫叶李、国槐和白蜡为多种蚧虫喜食树种。从空间和营养生态位来看,扁平球坚蚧最大,皱大球蚧最小,朝鲜球坚蚧的营养生态位大而空间生态位小;从生态位重叠来看瘤坚大球蚧和皱大球蚧、扁平球坚蚧和草履蚧以及和瘤坚大球蚧的重叠度均较高,朝鲜球坚蚧与瘤坚大球蚧的营养生态位重叠度最小。On the widespread occurrence of garden plants in Baoding, five kinds of serious harmful levels of scale insects and host selection and utilization of spaee and nutritional niche for a preliminary study. The results showed that： 5 kinds of scale insects in a different space, with more on the distribution of resource types, selection of host plants with preference, Prunus persica, Prunus ceraifera, Sophora japonica and Fraxinus chinensis for a variety of scale insect eating species. The point of view from the Space niche and Nutritional niche, Parthenolecanium eorni Bouche has the biggest space and nutritional niches , Eulecanium kuwanai Kanda has the smallest space and nutritional niches. Didesrrtococcus koreanus Borchsenius has the bigger nutritional niches and smaller space niches The point of view from the niche overlap , Eulecanium gigantean has the biggest space niche overlap with Eulecaniam kuwanai kandn, Parthenolecanium corni Bouche has the biggest space niche overlap with Drosicha corpulenta and Eulecanium gigantean , Didesmococcus koreanus Borchsenius has the smallest space niche overlap with Eulecanium gigantean.
