RESUMO
Oral susceptibility and vertical transmission of dengue virus type 2 (DENV-2) in an Aedes albopictus sample from Rio de Janeiro was estimated. The infection (36.7 percent) and transmission (83.3 percent) rates for Ae. albopictus were higher than those of an Ae. aegypti colony used as control, 32.8 and 60 percent, respectively. Fourth instar larvae and females descendants of 48.5 and 39.1 percent of experimentally infected Ae. albopictus showed to harbor the virus. The oral susceptibility and the high capacity to assure vertical transmission exhibited by Ae. albopictus from Brazil reinforce that this species may play a role in the maintenance of the virus in nature and be a threat for dengue control in the country.
