Laboratory studies of transovarial transmission of trivittatus virus by Aedes trivittatus.
Aedes trivittatus were experimentally exposed through a membrane to a concentration of trivittatus (TVT) virus in dog defibrinated blood of 10(3.4)-10(3.5) SMICLD 50/0.025 ml. Transovarial and transstadial transmission was demonstrated. Fifty-five percent of the infected mosquitoes tested transovarially transmitted TVT virus. TVT virus was isolated from 16% of the F1 generation progeny examined, including 19% of the larvae, 23% of adult females, and 10% of adult males.
