[Aim] The aim of this study was to optimize the breeding technology of parasitic wasps to provide a reference for the biocontrol of Tirathaba rufivena. [Method] The parasitic effects of the pupae parasitic wasp, Chouioia cunea(Hainan population) and the larval parasitic wasp, Bracon adoxophyesi, on four kinds of insects were studied in the laboratory, and the best inoculation proportion of wasp and host was also screened. [Result] B. adoxophyesi showed a better parasitic effect in Galleria mellonella larva than in Corcyra cephalonica and exhibited no parasitism to Tenebrio molitor and Zophobas atratus. The best inoculation proportion between B. adoxophyesi and G. mellonella larva was 1∶1 and 2∶1. The parasitic ratio and offspring produced by G. mellonella larvae were 76.67% and 34.60% in proportion of 2∶1, respectively. All pupae of the host assessed could be used to rear C. cunea with the best parasitic effect in T. molitor, considering the host rear cost and parasitic effect. The inoculation proportion of 2∶1 C. cunea to T. molitor led to 148.60. [Conclusion] The difference in host and inoculation proportion could influence the parasitic effects, the most suitable host for B. doxophyesi was G. mellonella, and the appropriate inoculation proportion of wasp and host was 1∶1 and 2∶1; while for C. cunea, the recommended host was T. molitor at a proportion of 2∶1.
