This study was carried out to investigate the development and fecundity of Liriomyze chinensis under different temperatures. Egg periods were 4.5, 2.9 and 1.9 days, larval periods 12.7, 5.8, 4.5, days, pupal periods 20.1, 16.3 and 13.0 days, and total development periods from egg to adult emergence were 32.5, 25.0 and 19.4 days under 20, 25, $30^{\circ}C$ of constant temperatures, respectively. Based on this results, developmental threshold temperatures were calculated as 13.0, 11.0 and $7.2^{\circ}C$ and total effective temperatures as 33.0, 86.1 and 293.6 degree-days for egg, larva and pupa, respectively. seventy-eight% of the tested files emerged within four hours and a half after lighting, and none was emerged after eight hours and a half. The longevities of male and female were 5.0 and 8.5 days and the female fly laid 165.8 eggs with her life and punctured 983.8 stipples at $25^{\circ}C$.
