Utilization of freeze-killed house fly, Musca domestica L., and stable fly, Stomoxys calcitrans L., pupae for development by the pteromalid parasitoids, Muscidifurax zaraptor Kogan and Legner, Pachycrepoideus vindemiae (Rondani) and Spalangia nigroaenea Curtis was investigated. All three species of parasitoids used both fly species as hosts. Parasitoid emergence from house fly and stable fly puparia was not significantly different for M. zaraptor and P. vindemiae. However, emergence of S. nigroaenea was significantly higher from house fly puparia than from stable fly puparia. When given a choice, all three pteromalid species preferred ovipositing on house fly pupae, as indicated by parasitoid emergence. Parasitoid emergence from house fly puparia comprised ca. 75, 58 and 90% of the total combined emergence from house fly and stable fly puparia for M. zaraptor, P. vindemiae and S. nigroaenea, respectively. For M. zaraptor, the proportion of female progeny from house fly puparia (ca. 60%) was significantly higher than that from stable fly puparia (ca. 47%). The proportion of females from house fly and stable fly puparia for P. vindemiae and S. nigroaenea was not significantly different.
