Imported MAYV cases are on the rise, leading to invasion concerns similar to Chikungunya and Zika viruses. Little is known about the range of mosquito species that are competent MAYV vectors. We tested vector competence of 2 MAYV genotypes for six mosquito species (Aedes aegypti, Anopheles gambiae, An. stephensi, An. quadrimaculatus, An. freeborni, Culex quinquefasciatus). Ae. aegypti and Cx. quinquefasciatus were poor MAYV vectors, and either were poorly infected or poorly transmitted. In contrast, all Anopheles species were able to transmit MAYV, and 3 of the 4 species transmitted both genotypes. The Anopheles species tested are divergent and native to widely separated geographic regions, suggesting that Anopheles may be important in the invasion and spread of MAYV across diverse regions of the world.
