摘要：
The influence of potato cultivar (Solanum tuberosum L. cvs. Albatros, Borwina, Fasan, Kormoran, Pirol, Salome, Romanze and Terrana) and leaf zone on the reproduction rate of green peach aphid, Myzus persicae (Sulzer) and potato aphid, Macrosiphum euphorbiae (Thomas) (Homoptera: Aphididae), was assessed in glasshouse experiments. Aphids were caged in five leaf zones of each cultivar. M. persicae prefers senescent leaves. Fecundity and reproductive rate of M. persicae were greater on the lower leaves than on upper leaves (P< 0.001). The total fecundity and reproduction rate of M. euphorbiae were greater on the upper leaves than on lower leaves (P< 0.001). The results showed that the reproduction rate of M. persicae and M. euphorbiae differed significantly (P< 0.05) among cultivars.
