 ,  , The striped fruit fly, Bactrocera scutellata, damages pumpkin and other cucurbitaceous plants. The developmental period of each stage was measured at seven constant temperatures (15, 18, 21, 24, 27, 30, and 33±1.0℃). The developmental time of eggs ranged from 4.2 days at 15℃ to 0.9 days at 33℃. The developmental period of larvae was 4.2 days at 15℃, and slowed in temperatures above 27℃. The developmental period of pupa was 21.5 days at 15℃ and 7.6 days at 33℃. The mortality of eggs was 17.1% at 15℃ and 22.9% at 33℃, Larval mortalities (1st, 2nd, 3rd) were 24.1, 27.3 and 18.2%, respectively, at 15℃, Pupal mortalities were 18.2% at 15℃ and 23.1% at 33℃. The relationship between developmental rate and temperature fit both a linear model and a nonlinear model. The lower threshold temperatures of eggs, larvae, and pupae were 12.5, 10.7, and 6.3℃, respectively, and threshold temperature of the total immature period was 8.5℃. The thermal constants required to complete the egg, larval, and pupal stages were 33.2, 118.3, and 181.2DD, respectively. The distribution of each development stages was described by a 3-parameter Weibull function.
