Females of Aedes aegypti (L.) infected with yellow fever virus by intrathoracic inoculation transmitted the virus to a small percentage of the adults of their F1 progeny. Infected offspring were obtained from surface-sterilised and untreated eggs, indicating that the virus was transovarially transmitted. Vertical transmission of yellow fever virus in mosquitoes may be an alternative mechanism for biological survival of the virus during adverse periods or in the absence of susceptible vertebrate hosts.
