中文摘要：由MEAM1烟粉虱以半持久方式传播的番茄褪绿病毒广泛分布于巴西茄科产区，如番茄、马铃薯和甜椒。番茄、马铃薯和甜椒在病毒获取和传播过程中的相互作用已有研究。在接种物种的选择试验中，将ToCV感染的马铃薯和番茄植株作为介体的接种来源，随后将病毒传播传播至番茄、马铃薯和甜椒植株。研究结果表明，番茄是最佳的接种来源，而甜椒对病毒感染最不敏感，与其他茄科植物比粉虱对辣椒的选择较少。
外文摘要：Tomato chlorosis virus, transmitted by Bemisia tabaci MEAM1 in a semipersistent manner, is widely spread in solanaceous producing region in Brazil, as tomato (Solanum lycopersicum), potato (S. tuberosum) and sweet pepper (Capsicum annuum). The interactions between tomato, potato and sweet pepper in the virus acquisition and transmission processes by the vector were studied. ToCV-infected potato and tomato plants were used as sources of inoculum for the vector, which subsequently transmitted the virus to tomato, potato, and sweet pepper plants in choice tests of inoculated species. For no choice tests, having tomato as the source of inoculum, ToCV transmission rates for tomato, potato and sweet pepper were 53.3%, 50%, and 16.6%, respectively. When ToCV-infected potato was the source of inoculum, the transmission rates for tomato, potato and sweet pepper were 30%, 46.6 and 3.3%, respectively. In the trials with free-choice and ToCV-infected tomato as the source of inoculum, virus transmission rates for tomato, potato and sweet pepper were 50%, 35 and 0%, respectively. With ToCV-infected potato as source of inoculum, transmission rates were 25%, 10 and 0% for tomato, potato and sweet pepper, respectively. When viruliferous insects were used in trials with free-choice for the vector, transmission rates were 40%, 45 and 0% for tomato, potato and sweet pepper, respectively. Based on statistical analysis using the logistic regression model, tomato was the best source of inoculum, while sweet pepper was the least susceptible to infection and less preferred by whiteflies than the other Solanaceae species.
