Abstract
The control of Myzus persicae on green pepper seedlings achieved by the release of flightless adults or second instar larvae of Harmonia axyridis was evaluated. Twenty flightless adults or 100 larvae per m2 were released in each plot at one time. The release of flightless adults was more effective to suppress the aphid density. The suppression of the aphid density was maintained for 10-14 days after release. The release of larvae using a net (15 cm×15 cm) more effectively suppressed the density of aphids compared to the release without a net. The aphid density remained suppressed for 7-10 days after release.
