During oviposition by endoparasitic wasps, secretions of maternal origin are injected into the host insect along with the egg(s). For many of these endoparasitoids in the families Ichneumonidae and Braconidae, the secretions contain endosymbiotic viruses (e.g., polydnavirus, entomopoxvirus), virus-like particles (VLPs) or ovarian proteins that aid in the manipulation or alteration of the host. Host regulation includes behavioral, biochemical and physiological changes, such as immunosuppression, altered hormone titers, and/or changes in protein expression, which functionally aid in the development of the parasitoid’s larvae. In most cases, the adult female also produces a proteinaceous venom that works synergistically or additively with the viral products. Some species also rely on embryonic factors such as teratocytes that may also contribute to host regulation and immune suppression by endoparasitoids. Typically, one or more of these maternally or egg-derived factors are necessary to...
