Resumo: An epidemic of Zika virus (ZIKV) illness that occurred in July 2007 on Yap Isl- in the Federated States of Micronesia prompted entomological studies to identify both the primary vector(s) involved in transmission - the ecological parameters contributing to the outbreak. Larval - pupal surveys were performed to identify the major containers serving as oviposition habitat for the likely vector(s). Adult mosquitoes were also collected by backpack aspiration, light trap, - gravid traps at select sites around the capital city. The predominant species found on the isl- was Aedes (Stegomyia) hensilli. No virus isolates were obtained from the adult field material collected, nor did any of the immature mosquitoes that were allowed to emerge to adulthood contain viable virus or nucleic acid. Therefore, laboratory studies of the probable vector, Ae. hensilli, were undertaken to determine the likelihood of this species serving as a vector for Zika virus - other arboviruses. Infection rates of up to 86%, 62%, - 20% - dissemination rates of 23%, 80%, - 17% for Zika, chikungunya, - dengue-2 viruses respectively, were found supporting the possibility that this species served as a vector during the Zika outbreak - that it could play a role in transmitting other medically important arboviruses.
