Abstract
The rice gall dwarf virus was transmitted in a persistent manner by the green rice leafhopper and was also transmitted through leafhopper eggs to 87% of the progeny. Transmission efficiency was the highest in Nephotettix nigropictus (Stal) followed by N. cincticeps (Uhler) and N. malayanus Ishihara and Kawase, while N. virescens (Distant) was an inefficient vector. Incubation period of the virus in N. nigropictus ranged from 12-18 days at 25.degree. C. Transmission efficiency of N. nigropictus increased as the acquistion access period was increased, reaching a maximum of 96% with a 12-day acquisition access period.
