Laboratory studies were carried out with two geographic strains of Aedes polynesiensis and one strain of Aedes aegypti to determine whether they could transmit Ross River virus (RRV). Both species were shown to be good vectors of RRV, but Ae. polynesiensis was the most susceptible. Ae. polynesiensis represents a new vector for this virus and the epidemiologic implications of RRV spread by both mosquito species are discussed.
