Transovarial Transmission of Japanese Encephalitis Virus by Mosquitoes

Abstract
Female Aedes albopictus and Aedes togoi mosquitoes infected with Japanese encephalitis virus either by intrathoracic inoculation or by ingestion of a virus-sucrose-erythrocyte mixture transmitted the virus to a small percentage of their F 1 progeny. Adult F 1 female Aedes albopictus thus infected transmitted the virus in turn to newly hatched chickens by feeding on them.
