Solution(By Examveda Team)

The vector of rice tungro disease is Nepholettix virescens.
Tungro virus disease is transmitted by leafhoppers, wherein the most efficient vector is the green leafhopper, Nephotettix virescens.
The disease complex is associated with the rice tungro baciliform virus (RTBV) and rice tungro spherical virus (RTSV). RTBV cannot be transmitted by leafhoppers unless RTSV is present.
