 "O. ochracea" infestation has been shown to affect the behavior and reproduction of host field crickets.Early in the infestation period, non-reproductive behavior is largely unimpaired because the parasitic larvae do not consume the digestive system or central nervous system of the host.After the larvae migrate to the host’s abdomen, the host’s mating, egg-laying, and fighting ability decline, most likely due to tissue damage caused by the larvae.
