With respect to both species number and mechanisms that lead to successful parasitism, endoparasitic wasps are known to inject secretions at oviposition, but only a few lineages use viruses or virus-like particles (VLPs) to evade or to suppress host defences. Extending our investigations to proteins encoded by open reading frames of certain ascoviruses and bracoviruses, hosts and bacteria, in the light of recent analyses about the involvement of the replication machinery of virus groups related to ascoviruses in lateral gene transfer [29] , we discuss the robustness and the limits of the molecular evidence supporting an ascovirus origin for ichnovirus lineages.	./cache/cord-000012-p56v8wi1.txt	./txt/cord-000012-p56v8wi1.txt
