Differential responses of body growth to artificial warming between parasitoids and hosts and the consequences for plant seed damage.

ABSTRACT: Temperature increase may disrupt trophic interactions by differentially changing body growth of the species involved. In this study, we tested whether the response of body growth to artificial warming (~2.2 °C) of a solitary koinobiont endo-parasitoid wasp (Pteromalus albipennis, Hymenoptera: Pteromalidae) differed from its main host tephritid fly (Tephritis femoralis, Diptera: Tephritidae; pre-dispersal seed predator), and whether the plant seed damage caused by wasp-parasitized and unparasitized maggots (larval flies) were altered by warming. In contrast to the significant and season-dependent effects of warming on body growth of the host tephritid fly reported in one of our previous studies, the effect of artificial warming on body growth was non-significant on the studied wasp.
