The dispersal of three species of plant-and leafhoppers was studied in a rice plant nursery and in the paddy field, using the mark-recapture method, i.e. Delphacodes striatella, the small brown planthopper (S.B.P.) ; Nephotettix cincticeps, the green rice leafhopper (G.R.L.) ; and Deltocephalis dorsalis, the zigzag striped leafhopper (Z.S.L.). When the rate of recapture was high, the relation between log-transformed numbers of recapture and distance from point of release was expressed by a linear regression. Dispersal rates strongly decreased with time. In the nurseries, the maximum distances of recapture after one day were : -S.B.P., 10〜15m ; G.R.L., 7〜13m ; Z.S.L., 10〜13m. After five days the maximum distances were : -G.R.L., 15m ; Z.S.L., 28m. In the paddy fields, G.R.L. had covered the maximum distances of 23〜41m in the first day, and of 26〜35m in the second and third days. In the nurseries, the mean distance of dispersal per day were estimated at 7.5m for S.B.P. ; 6.3m for G.R.L. ; and 7.1m for Z.S.L. In the paddy fields, the mean distance of dispersal for G.R.L. were estimated at 12.5m per day, and 13.7m per two days in Station B ; and 16.6m per three days in Station C.
