Abstract

The potential of a sylvatic vector to act as reservoir of yellow fever virus was assessed in Haemagogus equinus (Theobald). Mosquitoes from the Maje'75 laboratory colony and a Panamanian human isolated strain of yellow fever virus were used. Female mosquitoes infected with yellow fever virus had a minimum transovarial transmission rate of 1:5745. This is the first time transovarial transmission of yellow fever virus has been demonstrated in a New World sylvatic vector. Transovarial transmission of yellow fever virus in this sylvatic mosquito species may be an alternative mechanism for biological survival of the virus during adverse periods or in the absence of susceptible vertebrate hosts.
