Tests for Transmission of Pea Enation Mosaic Virus by Oligophagous Mustard and Grain Aphids. L. R. Nault, Associate Professor of Entomology, Ohio Agricultural Research and Development Center, Wooster 44691; Phytopathology 65:496-497. DOI: 10.1094/Phyto-65-496.

The oligophagous grain aphids, Macrosiphum avenae, Rhopalosiphum padi, and Schizaphis graminum transmit pea enation mosaic virus (PEMV) from pea to pea, a nonhost of the vector, if placed on barley, a natural vector host, for a 48-hour incubation period following virus acquisition. The oligophagous mustard aphids, Brevicoryne brassicae and Hyadaphis erysimi, failed to transmit PEMV when induced to feed on sinigrin-treated PEMV-infected pea and sinigrin-treated pea test plants.
