Transmission of geminiviruses by Bemisia tabaci


Bemisia tabaci (EPPO A2 quarantine pest) is known to transmit viruses of the carla-, poty-, clostero- and nepo-groups and especially of the geminivirus group (approximately 60 geminiviruses have been recorded - see Table 1). More than 20 colonies of B. tabaci, including B and non-B biotypes from different countries have been compared for their ability to transmit more than 20 geminiviruses. As a result, all colonies were able to transmit most geminiviruses, except two biotypes (E and J) and some viruses were transmitted more efficiently than others. The authors noted also that the viral coat protein is essential for vector recognition and transmission. They suggested that comparative studies on the molecular basis of transmission between transmissible viruses and those which are no longer transmissible could provide useful tools for future integrated pest management programmes against B. tabaci.
