This study was conducted to estimate temperature effect on the hatching success of Asian Gypsy Moth (AGM), Lymantria dispar (Linne) in different temperature conditions (15, 20, 25, 30, and 35℃). The egg masses were collected during winter season and stored in cold room (4℃). The hatching rate was evaluated from the number of hatched caterpillar for period of 50 days. As a result, hatching rates were 89.80, 92.94, 95.51, 62.02, and 18.35% at 15, 20, 25, 30, and 35℃, respectively. The optimal temperature on the hatching success of AGM egg might be 20~25℃.
