Technical Abstract: The Reoviridae are large, architecturally-complex viruses containing segmented double-stranded RNA genomes that infect plant hosts through insect vectors. Rice Dwarf Virus (RDV) is a leafhopper-transmitted member of the Phytoreoviridae that infects graminaceous hosts. The Glassy-winged sharpshooter, GWSS, Homalodisca coagulata, has become established in California and has drawn attention as the main vector of Pierce’s Disease of grapes, however, recent findings suggest that other crops are also at risk from plant diseases which may be being transmitted by this fast spreading insect pest. A Rice Dwarf-like virus was isolated from the salivary glands of the GWSS. The presence of Rice Dwarf-like virus indicates that the GWSS may be causing more economic damage than just as a vector of Pierce’s Disease, and expanded monitoring in other crops that are susceptible to viruses within the Phytoreoviridae would be prudent.
