The American Serpentine Leafminer, Liriomyza trifolii (Burgess) was reared at 25℃ on kidney bean, pakchoi, tomato, cherry tomato, celery, gerbera, chrysanthemum and melon, and at different temperatures on tomato. The pupation rates at 25℃ varied from 56.2% on melon to 97.8% on kidney bean and were significantly different between crops. The adult emergence rates varied from 82.8% on celery to 96.5% on tomato. There were no large differences in the mean generation time between crops. Large differences in the net reproductive rate were found between crops, ranging from 25.21 on tomato to 271.99 on pak-choi. The intrinsic rates of natural increase on kidney bean, pak-choi, tomato, cherry tomato, celery, gerbera, chrysanthemum and melon were 0.2384,0.2268,0.1607,0.1684,0.2008,0.1866,0.1709 and 0.1429,respectively. The reproductive rates per day varied from 1.269 on kidney bean to 1.154 on melon. The hatchabilities on tomato were not significantly different between different temperatures, but the pupation rates and emergence rates were significant different between temperatures. The female fecundity varied from 3.3 at 15℃ to 29.4 at 25℃, and female longevity was negatively correlated with temperature. The mean generation times varied from 55.85 at 15℃ to 14.27 at 30℃. The net reproductive rate was 25.21 at 25℃, and the intrinsic rates of natural increase at 15℃, 20℃, 25℃ and 30℃ were -0.0042,0.0655,0.1607 and 0.0995,respectively. The population growth rate of L. trifolii was highest at 25℃.
