Table 2 Infection, disseminated infection and transmission rates of Ae. caspius from Catalonia and Ae. aegypti PAEA populations artificially fed with Suriname and MR766 ZIKV strains at a titer of 7 log10 TCID50/ml. Viral detection was performed by the visualization of cytopathic effect on cells and RT-qPCR assays

From: European Aedes caspius mosquitoes are experimentally unable to transmit Zika virus
