A parasitic wasp suppresses host pupation by microRNA‐mediated transcriptional silencing of OfE93 Parasitism by Macrocentrus cingulum induces miR-281a-5p upregulation in the host Ostrinia furnacalis larvae, which suppresses OfE93 expression and arrests pupation. This finding reveals a miRNA-media...
