Summary:Patch exploitation strategies have received considerable attention since the development of the marginal value theorem. As an excellent biological research object, parasitoids have been extensively studied in regard to patch exploitation, including the effect of parasitoid states. Longevity and fecundity are state-dependent traits that may affect foraging decisions, oviposition behavior and patch residence time. We investigated the impact of Trichopria drosophilae (Hymenoptera: Diapriidae) states on patch exploitation. As an important endoparasitic wasp in the Drosophila pupal stage, T. drosophilae has potential as a biological control agent. Our results demonstrate that female age, food availability and mating state modulated the patch residence time of T. drosophilae . In addition, the time taken for females to enter a patch was changed by oviposition experience, age, and food availability. Our results are consistent with models that predict that the patch exploitation strategy must be fundamentally dynamic in parasitoids. Differences between patch foraging behavior in wasps with different internal state can be explained by the maximum fitness they achieved.
