European Aedes caspius mosquitoes are experimentally unable to transmit Zika virus
Background: Aedes caspius (Pallas, 1771) is a foodwater mosquito species widely distributed in the Western Palae‑ arctic. As an anthropophilic species, its role as an arbovirus vector may be the key for understanding the transmission cycle of certain diseases in Europe such as Zika virus (ZIKV). Con...

ZIKV is an arbovirus that has provoked a widespread epidemic in the Pacifc region (2007– 2013) and in the Americas (2015–2016).

In the present study, the vector competence of a European population of Ae. caspius was evaluated for two ZIKV lineages, the Suriname ZIKV strain (Asian lineage) and the MR766 ZIKV strain (African I lineage).

Aedes caspius was unable to produce a disseminated infection and virus transmission at any of the tested time points.
