Rice Hoja Blanca Virus - Vector

Vector

The planthopper Tagosodes orizicolus (Muir) is both a host and vector of RHBV. The virus is acquired through feeding on an infected plant, and there is a period of 17–22 days of viral propagation before the planthopper becomes viruliferous. There is a high rate of transovarian transmission to the progeny, and these nymphs can transmit the virus shortly after they emerge.
