Abstract
Rate of transmission of ToLCV by B. fabaci from tomato to tomato was 80–100 per cent when single whitefly was used per seedling and survived 24 h after inoculation. Female adults were found to be more efficient (86.66–100%) in transmitting ToLCV than males (26.66–33.33%) when single whitefly per seedling was used. Five adult whiteflies were required for 100 per cent transmission of ToLCV from tomato to tomato, when acquisition and inoculation access periods were 24 h each. The minimum acquisition access and inoculation access periods were 0.10 and 0.20 hours, respectively. A latent period of 6 h was necessary for B. fabaci to became viruliferous.
