Analysis of transmissibility of Tomato yellow leaf curl virus by Bemisia tabaci fed on infected tomato tolerant cultivar

Abstract

Effect of tomato tolerant cultivar to Tomato yellow leaf curl virus on acquisition and transmission by Bemisia tabaci was examined. Infected Solanum lycopersicon L. ‘TY Misora86’, showed asymptomatic infection of the disease, but contained detectable viral DNA in the upper leaves, which was evaluated by PCR analysis. Efficiency of virus acquisition by adult whiteflies fed on the infected tolerant cultivars for 72 hours was varied (25.0–81.3%), but was seemed to be lower than those of adults fed on the infected susceptible cultivars (92.0–100%). Subset of these adults were able to transmit the virus to susceptible plants, however, percentage of infected plants were 0–20.0%, which were relatively lower than those by viruliferous adults fed on infected susceptible cultivars (50.0–75.0%).
