Lymantria dispar (Linne), gypsy moth, is known as euryphagous insect and one of forest pests having wide range of host. Female of European Gypsy Moth (EGM) are flightless whereas those of the Asian Gypsy Moth (AGM) are strong fliers. So, we studied flight ability of female AGM by using flight mill device. The flight measurements of female AGM are recorded for an hour using 1- and 2-day-old mated and unmated individuals. As a results, mated females were observed more active the unmated. But, flight speed of unmated females are faster than mated. Flight frequency wasn't showed any significant difference between mated and unmated females.
