Abstract: Since the 1950s, artificial reproduction of Trichogramma and their application technologies have been systemically studied in China, and a great success in selection and application of intermediate hosts suitable for mass production has been achieved. In recent years, we have made some progresses in mass production of Trichogramma with the large eggs of Chinese oak silkworm, Antheraea pernyi Guerand small eggs of rice moth, Corcyra cephalonica (Stainton). In this paper, we summarized the new progresses in mass production with large eggs from the matched production facilities and processes, and with small eggs from the artificial diet composition and breeding device for larvae and collection methods for adult moth. In addition, we introduced the technologies with releasing Trichogramma for one time to long-term control corn borers and mixed-releasing two Trichogramma species produced using large eggs and small eggs to control rice striped stem borers. Ever since 2004, the total release area was approximately 13 million hectares. Overall, the great success has been achieved in the biological control of agricultural pests with Trichogramma in China. Finally, the problems and development trends in mass production of Trichogramma in future were discussed.
