Tang et al. show that microRNAs derived from an endoparasitic wasp Snellenius manilae bracovirus (SmBV), SmBV-miR-199b-5p and SmBV-miR-2989, target domeless and toll-7 in its host Spodoptera litura, suppressing the innate immune responses of parasitized hosts. This study provides insights into how parasites maximize their fitness by regulating host immunity.
