The relationship between development and temperature in Recilia dorsalis was analyzed by laboratory experiments in applying the following equations ; 1/Y=-0.1037+0.0076X (γ=0.9820) for the egg stage, and 1/Y=-0.0736+0.0053X (γ=0.9849) for the nymphal stage, where Y is the duration of the developmental period (days) and X is the temperature (℃). Developmental zero and effective accumulative temperature were then estimated at 13.7℃ and 127.9℃ for the egg stage and 14.0℃ and 193.9℃for the nymphal stage, respectively. Developmental rate of the nymphal stage did not increase at temperatures exceeding 30℃. Daily number of eggs oviposited by a female increased day by day from 3 days until 10 days after emergence and reached a constant level, ca. 5 eggs/female/day, until 0-2 days before death. The mean pre-oviposition period was 4.5 days. Great variations were, however, observed in the number of eggs oviposited, namely mean fertility : 39.6 eggs/female, mean duration of oviposition : 11.8 days, and mean survival period : 14.7 days. On the basis of these data and daily record of temperature, R. dorsalis was estimated to undergo 4 generations in a year in Kagawa Pref.
