In the transmission of rice waika virus (RWV) by the green rice leafhopper N. cincticeps, transmission efficiency slightly decreased in older adults, but no difference in efficiency was demonstrated between sexes. Acquisition and inoculation threshold periods were about 30 min. The rate of infective insects increased as the acquisition feeding period was increased to 12 h. No definite latent period in the leafhopper was demonstrated. Nymphs lost their infectivity after they molted. Leafhopper adults retained infectivity for a short period after the termination of acquisition feed. Infectivity decreased drastically with time and the longest retention period was 2 days at 25.degree. C. After losing infectivity, insects became reinfective by fresh access to a diseased plant. RWV is classified as a semipersistent leafhopper-borne virus based on the definition by Sylvester (1969).
