Abstract: The effects of high temperature and time combinations were tested on the rate of emergence of Liriomyza sativae Blanchard. The corrected mortality rate was 67.2% at 50℃ after 2 h treatment. The mortality rate at 44℃ for 2 h was close to 50℃. Others treatment had significant difference compared to 50℃. No adult was emergence at the treated of 50℃ for 4hours, 48℃ for 24hours and 40-46℃ for 72hours, that indicating the temperature and period had a direct effect on the mortality of pupae. Field experiments showed that no adult was emerged when treated by high- temperature windtight shed for 5-7days, and markedly reduced the population of Liriomyza sativae Blanchard.
