Mosquitoes transmit various pathogens causing diseases like Zika, Dengue, West Nile and Chikungunya. They also harbour insect-specific viruses (ISVs) and Wolbachia, which can block arbovirus transmission. This study investigated the prevalence of Orthoflavivirus and Wolbachia in mosquito populations from three provinces in TcFCrkiye. Mosquitoes were collected using CDC Miniature Light traps in 2022-2023. Morphologically identified specimens were pooled (1-10 individuals) and screened for Orthoflavivirus and Wolbachia via PCR and confirmed by Sanger sequencing. Infection prevalence was estimated using the maximum likelihood method. Mosquito taxa richness across provinces was estimated using the abundance-based, non-parametric Chao1 index. Among 8766 mosquitoes (11 taxa) collected, Culex perexiguus, Ochlerotatus caspius and Anopheles claviger were most abundant. Anopheles flavivirus (AnFV) detected in one Oc. caspius pool, while Wolbachia sequences belonging to supergroup B were detected in An. claviger, Cx. pipiens s. l., Cx. perexiguus and Oc. caspius, with an overall infection prevalence of 0. 0119 (95% CI: 0. 008-0. 0161). The richest mosquito fauna was detected in Ankara, followed by Adana, and Cankırı. This study provides new insights into mosquito richness and the prevalence of Orthoflavivirus and Wolbachia in TcFCrkiye, contributing to vector surveillance and the potential use of Wolbachia in mosquito control strategies.
