Calling male field crickets (Gryllus spp.) are acoustically located and subsequently parasitized by the parasitoid fly, Ormia ochracea (Diptera: Tachinidae). Parasitism by O. ochracea results in cricket death. The reproductive compensation hypothesis posits that when a host's residual reproductive value decreases, it would be adaptive for that host to shift its resources into current reproduction. Reproductive compensation has not been observed in the cricket-fly system. Here we review the studies to date that have investigated reproductive compensation in the cricket-fly interaction, in an attempt to understand why crickets do not compensate for their future reproductive losses. We conclude that the cricket-fly interaction may not be an ideal system in which to investigate reproductive compensation and furthermore, that reproductive compensation has been poorly investigated in this system.
