Abstract: Arma chinensis is a predator that can effectively suppress a wide range of agricultural and forestry insect pests. Mass rearing of A. chinensis at low costs for use as biocontrol agents is of great significance in sustainable pest management. In this study, the content of Antheraea pernyi pupae was added to former insect-free artificial diet formulated using proteomic methods. Over 3 generations of rearing, the predator was smaller and nymphal development was extended significantly in the diet-fed A. chinensis compared to those reared on pupae of A. pernyi. However, adult weight, fecundity and longevity were higher or longer for the diet-fed A. chinensis compared to those reared on former artificial diet formulated using proteomic methods. The A. chinensis reared on diet with 50% (v/v) content of A. pernyi pupae showed an increased fecundity by 231.05% compared to those reared on former artificial diet formulated using proteomic methods and the female and male adults lived as long as 83.6 d and 103.7 d, respectively. The results indicate that the diet with 50% content of A. pernyi pupae is more suitable for rearing A. chinensis compared to those with 75% content of A. pernyi pupae, considering the rearing costs and the biological performance of the predator.
