This report details the first detection of the Oropouche virus (OROV) in Culicoides insignis in the Ucayali region (Peruvian Amazon) during an outbreak study in 2024. Captures conducted in peri-urban and rural areas showed that C. insignis accounted for 96.7% of the collected Culicoides specimens. RT-qPCR testing confirmed the presence of the virus in two C. insignis pools, establishing this species as a potential OROV vector in the study area, thereby contributing to the understanding of the viruss epidemiology in the Amazon region.
