  abstract = {{S}uperparasitism refers to the oviposition behavior of parasitoid females who lay their eggs in an already parasitized host. {T}his often yields intense competition among larvae that are sharing the same host. {W}hy would a female oviposit in such hostile habitat instead of looking for a better quality, unparasitized host? {H}ere we present a continuous-time model of host-parasitoid interaction and discuss alternative scenarios. {T}his model is first used to analyze the evolution of the superparasitism behavior of a solitary proovigenic parasitoid under both time and egg limitation. {T}hen, following the recent discovery by {V}araldi et al., we allow the parasitoid to be infected by a virus that alters the superparasitism behavior of its host to enhance its own horizontal transmission. {T}he analysis of the coevolution of this manipulative behavior with the oviposition behavior of uninfected females clarifies and quantifies the conflict that emerges between the parasitoid and its virus. {T}he model also yields new testable predictions. {F}or example, we expect that uninfected parasitoids should superparasite less after coevolving with the manipulative virus. {M}ore generally, this model provides a theoretical framework for analyzing the evolution of the manipulation of parasitoid life-history traits by microparasites.},
