Abstract

The flight potential of Nephotettix virescens (Distant), the most important vector of rice tungro virus disease, was assessed using tethered flight techniques. Most individuals tested were not willing to fly in response to stimulation, or flew for very short times. A small proportion of leafhoppers flew for long periods and one female flew for almost 7 h, indicating the potential for long distance dispersal of insects and inoculum. Few individuals flew before four days of age and thereafter flight profiles were similar for insects aged between four and 12 days. Mature females were more flight willing when kept as adults in mixed groups with males than when caged separately. There was no consistent effect on flight performance when insects were reared on rice varieties with different levels of leafhopper resistance. The flight activity of N. virescens was greater when leafhoppers were reared on mature, compared with young, rice plants. Leafhoppers reared through one generation on tungro-diseased rice plants were less willing to fly than individuals maintained on healthy plants of the same age and variety, whereas those tested after a 24-h access period to tungro-diseased plants were more flight-willing. The results are discussed in relation to the spread of tungro and to management interventions for the control of the disease.
