CIMMYT. 1990. p. 286-28991-013583Summary: In England barley yellow dwarf virus (BYDV) is a problem associated mainly with autumn-sown cereals. The total number of two important vector species, Rhopalosiphum padi (L.) and Sitobion avenae (Fabricius), often differ greatly in suction trap samples in autumn. Three alate morphs of the dioecious R. padi are present in autumn, but only alate exules will colonize cereals, while gynoparae and males are in search of the primary host, Prunus padus L. In contrast, all alate morphs of the monoecious S. avenae will colonize cereals. Hence, differences in densities on crops, at this time, are usually much less pronounced.
