The field tests demonstrated that control effects of the mixture fenpropathrin+abamectin 19% EC at the rate of 9.5 g (a. i.)/667m2 to Liriomyza sativae Blanchard in 3～11days after application was 87.22%～91.32%, which was significantly better than that of fenpropathrin, and its effect in 3～7 days after application was significantly better than that of abamectin, but after 11 days there was no difference among them. The control effects at the rate of 7.5 g(a.i)/667m2, 5.625 g(a. i.)667m2 and 3.75 g(a. i.)/667m2 to L. sativae in 3～11 days after application was 85.59%～89.09%, 77.15%～85.95% and 78.52%～79.96%, respectively.
