摘　　要：考氏白盾蚧Pseudaulacaspis cockerelli(Cooley)是重要的观赏植物害虫,在我国分布广泛,本文对四种不同寄主同一寄生部位和同一寄主不同寄生部位的雌成虫形态及一龄若虫形态作了详细研究,并记述了二龄雌虫、二龄雄虫和雄成虫形态特征.研究表明,所观察一龄若虫形态相同,雌成虫形态有不同程度的变异,但难以截然划分为食干型和食叶型.附有5幅显微形态图.Pseudaulacaspis coclerelli(Cooley),an important pest insect feeding on quite variouskinds of ornamental plants,is widely distributed in China.The adult females of this speciescollected from various hosts,with median lobes varied in a practically continuous seriesfrom prominences to ones sunken into the apex of the pygidium,occur both on the barkand leaves,indicating that the variation of the median lobes is not entirely related to the fe-eding sites.The morphology of the adult female,adult male,1st instar larva,2nd instar fe-male,and 2nd instar male is described and illustrated.
