[Objectives]  To investigate the potential of using Aphidoletes aphidimyza (Rondani) reared on Megoura japonica (Matsumura) as a biological control for Myzus persicae (Sulzer), and thereby clarify the benefits of conducting short-term prey habituation before releasing aphid gall mosquitoes for biological control purposes. [Methods]  The predatory responses of A. aphidimyza feeding on either M. japonica or M. persica were measured and compared under laboratory conditions. [Results] The predatory response of A. aphidimyza fed on M. japonica for a long period and M. persica for a short period was consistent with a Holling type Ⅱ model; an initial increase that subsequently levelled off with increasing prey density. A one-way analysis of variance indicates that there was no significant difference in the daily number of prey consumed by A. aphidimyza in the two treatment groups (P > 0.05). The instant attack rates of each treatment group on M. japonica and M. persicae were 0.170 2 and 0.155 4, respectively, and their respective prey processing times were 0.116 9 d and 0.107 0 d, respectively. A one-way analysis of variance indicates that the density of A. aphidimyza own had no significant (P > 0.05) effect on the daily average consumption of M. persicae. [Conclusion]  A. aphidimyza raised on M. japonica do not require short-term exposure to M. persicae before release.
