  1. Notes: Total RNA from control and ZIKV-infected (PRVABC59 strain) whole mosquitoes were extracted 7 days post-infection and used as template for qRT-PCR reactions, using 1107-FAM probe and NS5-2362F/NS5-2457R or ZIKV 1086/ZIKV 1162c primers. Positive controls consisted of total RNA from Vero cells infected with ZIKV PRVABC59 strain
