This study verified the host species of the parasitoid Hemencyrtus herbertii Ashmead (Hymenoptera: Encyrtidae), in Lavras, Minas Gerais, Brazil. The pupae were obtained by the flotation method. They were individually placed in gelatin capsules until the emergence of adult flies or their parasitoids. The overall occurence of parasitism was 6.5%. The occurrence of parasitism presented in the hosts Chrysomya megacephala (Diptera: Calliphoridae) and Sarcodexia lambens (Diptera: Sarcophagidae) was 1.3% and 29.4%, respectively.
