Abstract
The life table parameters of Thrips palmi Karny were determined at four constant temperatures, 15, 21, 25, and 30°C, on eggplant leaves for three generations. The results indicated that the age-specific fecundity (mχ), the daily fecundity (fχ5), and the age-specific maternity (lχmχ) were highest at 25°C. The intrinsic rate of increase (r) rose from 0.033 day-1 at 15°C to between 0.046 and 0.157 day-1, then dropped to 0.118 day^(-1) at 21, 25°and 30°C, respectively. The net reproductive rate (R0) was highest at 25°C at 18.6 eggs/individual. The mean generation time (T) shortened gradually from 15 to 30°C, but was only one day shorter at 30°C than at 25°C. The standard error of r, λ, R0, and T were estimated by using the Jackknife method. Accordingly, the management strategy for T. palmi was suggested based on this study.
