These studies were carried out to investigate the oviposition and host feeding characteristics of Neochrysocharis formosa Westwood, an endoparasitoid of Liriomyza trifolii. N. formosa female oviposited inside the abdomen at the rear end of the host larva. Number of eggs and host feeding per day of N. formosa tended to increase as temperatures go up. The ratio of oviposition and host feeding of N. formosa were 0.5, 0.9, 1.0 and 1.0 at 15, 20, 25, and 30$^{\circ}C$, respectively. In 25$^{\circ}C$, number of eggs and host feeding were 176.0 and 188.7, respectively, and aduly female longevity was 11.8 days. N. formosa female preferred to the 3rd rather than 1st and 2nd larva for oviposition and host feeding.
