. An investigation of the vertical transmission of hepatitis B virus (HBV) in Culex quinquefasciatus Say revealed the presence of low levels of the virus in adult Fi progeny from the first ovarian cycle of mosquitoes infected by feeding on HBV positive human blood. HBV was not transmitted vertically during the second, third and fourth ovarian cycles nor to the F 2 generation. The salivary glands, ovaries and faeces of the Fj generation did not contain detectable levels of HBV. Progeny of female Cx quinquefasciatus mated with F 1 males were negative for HBV.
