Popis: | Muscidifurax zaraptor was more efficient at parasitizing house fly pupae than was Urolepis rufipes. Both wasp species preferred to oviposit on unparasitized pupae. Ovipositional restraints of M. zaraptor broke down at high parasitoid-to-host ratios; superparasitism caused a reduction in parasitoid emergence and in the percentage of females that emerged. Under competitive conditions, reductions in parasitoid emergence occurred for both species, but M. zaraptor dominated and showed greater discrimination between species. |
