Transovarial Transmission of Begomoviruses in Bemisia tabaci

Transovarial transmission of viral nucleic acid in insect vectors, or more precisely of viral infectivity, can be very important in maintaining a source of infection and therefore has great epidemiological relevance. The first clear case of transovarial transmission of an arbovirus demonstrated the ability of sand fly and black fly vector populations to maintain Vesicular stomatitis virus without a vertebrate host (Tesh et al. 1972). This phenomenon is also known in the plant world and continues to receive attention from virologists
