粉虱是多种农作物的重要农业害虫，主要通过植物病毒传播造成巨大的经济损失。在不同种类的粉虱中，白粉虱和烟粉虱 MEAM1（B 生物型）传播克尼病毒番茄失绿病毒 (ToCV)。先前的研究报告称，感染病毒的植物会影响不同种类粉虱的吸引力和行为。在这项研究中，我们评估了 ToCV 感染和健康番茄上 T.vaporariorum 和 B.tabaci MEAM1 的卵数量、卵孵化率和成虫的羽化率。此外，还对两种粉虱进行了 ToCV 传播测定。 ToCV感染不影响T.vaporariorum的卵数和卵孵化率；而感染 ToCV 的番茄成虫的出现量减少了 37.3%。相比之下，感染 ToCV 的番茄强烈影响烟粉虱 MEAM1 卵孵化率和成虫出苗率，分别降低 41.8% 和 92.4%。关于病毒传播，T.vaporariorum 传播 ToCV 的效率 (35.7%) 低于 B.tabaci MEAM1 (78.6%)。我们的数据表明，当取食 ToCV 感染的番茄植株时，T.vaporariorum 的性能比 B.tabaci MEAM1 的性能受到的影响更小。
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 MEAM1 (B biotype) transmit the crinivirus Tomato chlorosis virus (ToCV). 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 MEAM1 on ToCV-infected and healthy tomatoes. In addition, ToCV transmission assays were conducted with both whitefly species. ToCV 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 ToCV-infected tomatoes. By contrast, ToCV-infected tomatoes strongly affected the B.tabaci MEAM1 egg hatching rate and emergence of adults with reductions of 41.8% and 92.4%, respectively. Regarding virus transmission, T.vaporariorum transmitted ToCV with lower efficiency (35.7%) than B.tabaci MEAM1 (78.6%). Our data suggest that the performance of T.vaporariorum is less affected than that of B.tabaci MEAM1 when feeding on ToCV-infected tomato plants.
