Antiviral immunity in Drosophila involves RNA interference and poorly characterized inducible responses. Here, we showed that two components of the IMD pathway, the kinase dIKKβ and the transcription factor Relish, were required to control infection by two picorna-like viruses. We identified a set of genes induced by viral infection and regulated by dIKKβ and Relish, which included an ortholog of STING. We showed that dSTING participated in the control of infection by picorna-like viruses, acting upstream of dIKKβ to regulate expression of Nazo, an antiviral factor. Our data reveal an antiviral function for STING in an animal model devoid of interferons and suggest an evolutionarily ancient role for this molecule in antiviral immunity. Goto et al. show that the kinase dIKKβ and the NF-κB factor Relish control replication of picorna-like viruses in flies through induction of antiviral genes, including a homolog of STING. A STING-IKKβ-NF-κB cassette participates in resistance to picorna-like viruses, pointing to an evolutionarily ancient role of STING in antiviral immunity.
