AbstractSuperparasitism created a food shortage and thereby reduced survival and size of adult Nasonia vitripennis (Walk.) (Hymenoptera: Pteromalidae) reared on pupae of the house fly, Musca domestica L. Superparasitism also reduced the percentage of females in the adult progeny but had no effect on rate of development, ability to emerge, or incidence of diapause in N. vitripennis.

AbstractDevelopment time for the parasite Nasonia vitripennis (Walk.) was shorter on young pupae (less than 48 hours old at 24.5 ± 0.5 °C) than on older pupae of the house fly, Musca domestica L. This was primarily because of intrinsic differences between young and old house-fly pupae as hosts. Though less important, two other conditions in young hosts favoured a shorter mean development period for N. vitripennis: first, the smaller proportion of very small parasites, which mature more slowly than the larger ones; and, second, the greater number of parasite larvae per host, which is associated with more rapid development in this species.

AbstractFemales of Nasonia vitripennis (Walk.) lay a smaller percentage of fertilized (i.e. female) eggs on house fly, Musca domestica L., pupae previously parasitized by their own species, by Muscidifurax zaraptor K. & L., or by Spalangia cameroni Perk. (Hymenoptera: Pteromalidae) than on unparasitized hosts. They respond to changes in the fly pupae associated with death, and in the case of house flies attacked by N. vitripennis, to "venoms" injected at that time or to changes unrelated to death. By not fertilizing eggs that they lay on attacked hosts, the females also conserve sperm, for immature N. vitripennis on previously-attacked fly pupae are usually killed by parasite larvae already present.

AbstractFemales of Nasonia vitripennis (Walk.) (Hymenoptera: Pteromalidae) laid fewer eggs on parasitized than on unparasitized pupae of the house fly, Musca domestica L. Chemical and/or physical conditions of parasitized pupae are detected by the female’s ovipositor, causing this restraint. These conditions may in part result from the host’s death, caused by earlier parasitization, but other factors are also involved. These may include venom injected by the female parasite before she lays, and internal injury to the host resulting from insertion of the parasite’s ovipositor. The female parasite does not discriminate because of physical or chemical traces on the surface of parasitized puparia, of eggs or a surface wound on the pupa, or of absence of heart beat in the pupa.

AbstractInferences regarding the value of Nasonia vitripennis in the natural control of Musca domestica based on laboratory research should consider the general absence of this parasite on that host in nature. Predominant natural parasites of M. domestica are listed.
