Abstract: In order to reduce the cost of mass rearing Aphidius gifuensis Ashmead, this experiment compared dilution rearing methods with normal rearing methods in terms of rearing quantity. The results showed that the number of A. gifuensis (245.5 heads per plant) reared by dilution method was more than that by normal methods (182.2 heads per plant), and the efficiency of the former method is 34.7% higher than the latter. In summary, the method of dilution rearing is much more efficient, which is worthy for promotion.

Key words: Aphidius gifuensis, Myzus persicae, mass rearing
