Abstrakt: Muscidifurax raptorellus is a parasitoid wasp which is commonly used in the biological control of harmful dipterans in stables. In this study, the adaptation of M. raptorellus to different species of dipteran hosts—detrimental to both agriculture (Diptera: Tephritidae) and livestock (Diptera: Muscidae)—as well as several quality parameters of this commercial parasitoid was assessed under laboratory conditions. Our results showed a higherparasitism rate of M. raptorellus onmuscidthan ontephritid hosts and a significant effect of the natal host on M. raptorellus female longevity and fertility; however, despite this and the innate preference formuscid hosts, M. raptorellus showed similar fecundity, fertility and sex ratios when reared on pupae of Ceratitis capitata and on muscidpupae. Furthermore, both fertility and the sex ratio of commercially available M. raptorellus individuals showed values within an acceptable range of quality. Our results suggest that M. raptorellus could be recommended as a natural enemy in biological control programmes against dipteran pests harmful both to livestock and cultivated plants.
