Evidence for Receptor-Mediated Endocytosis Regulating Luteovirus Acquisition by Aphids

The ability of five cereal grain aphid species to acquire four vector-specific isolates of barley yellow dwarf luteoviruses was tested. Aphids from New York clones of Rhopalosiphum maidis, R. padi, Schizaphis graminum, and Sitobion avenae acquired the New York type isolates of MAV, PAV, RMV, and RPV when fed on infected plants, regardless of the ability of each species to transmit the virus. Aphids from a California clone of Metopolophium dirhodum acquired MAV, PAV, and RMV, but not RPV []
