Abstract: We introduced the technology research and its extention application status of control Myzus persicae by Aphidius gifuensis, and evaluated of control Myzus persicae effects using Aphidius gifuensis as well.We thought that we should promote the large scale propagation and its releasing level in the future on Aphidius gifuensis extension,and the propagation equipment and its professional team construction,that can promote the industrialization development and using of Aphidius gifuensis,and reinforce the status and its function of Aphidius gifuensis in biocontrol of Myzus persicae
