Researchers reported the world’s first gene-edited biting midges (Culicoides), opening a new path for studying how these vectors transmit livestock diseases. The advance targets Culicoides, small blood-feeding insects responsible for spreading bluetongue virus, Schmallenberg virus, and epizootic hemorrhagic disease virus—major drivers of losses in global livestock production. Because Culicoides are only 1–4 mm, the lab work has historically been difficult, limiting mechanistic studies of vector competence. The gene-editing capability described in the report is intended to make those studies tractable by enabling controlled experimentation on the biology of transmission. If the approach scales, it can support vaccine, surveillance, and vector-control strategies by pinpointing which genetic factors influence viral spread rather than relying on correlative studies alone.
