(1987). v. 94(6) p. 578-583Summary: The life cycle of the bird cherry-oat aphid, Rhopalosiphum padi, was studied comparing specimens carrying BYDV (PAV isolate) and virus free. Sections of leaves of wheat and oats, infected with BYDV and virus-free, were used to rear the aphids in Petri dishes. Daily observations of selected parameters of the life cycle were recorded in all treatments. The data, analyzed separately for each crop, showed the aphids had a shorter longevity and adult life on virus-infected wheat. There were also differences for longevity when analyzing wheat cultivars x BYDV-infection. Feeding on virus-infected wheat increased reproductive capacity of the aphids, while no significant differences were detected when using oats
