Whiteflies are important agricultural pests of several crops and cause great economic losses, mainly by the transmission of plant viruses. Among the different species of whiteflies, Trialeurodes vaporariorum and Bemisia tabaci MEAM 1 (B biotype) transmit the crinivirus Tomato chlorosis virus (To CV ). Previous studies report that virus‐infected plants can influence the attractiveness and the behaviour of different species of whiteflies. In this study, we evaluated the number of eggs, egg hatching rate and emergence of adults of both T. vaporariorum and B. tabaci MEAM 1 on To CV ‐infected and healthy tomatoes. In addition, To CV transmission assays were conducted with both whitefly species. To CV infection did not influence the number of eggs or egg hatching rate of T. vaporariorum ; whereas the emergence of adults was reduced by 37.3% on To CV ‐infected tomatoes. By contrast, To CV ‐infected tomatoes strongly affected the B. tabaci MEAM 1 egg hatching rate and emergence of adults with reductions of 41.8% and 92.4%, respectively. Regarding virus transmission, T. vaporariorum transmitted To CV with lower efficiency (35.7%) than B. tabaci MEAM 1 (78.6%). Our data suggest that the performance of T. vaporariorum is less affected than that of B. tabaci MEAM 1 when feeding on To CV ‐infected tomato plants.
