Tomato chlorosis virus (genus Crinivirus, family Closteroviridae) (ToCV) is rapidly emerging, causing increased damage to tomato production worldwide. The virus is transmitted in a semipersistent manner by several whitefly (Hemiptera: Aleyrodidae) species and is expanding its geographical and host ranges associated with the emergence of whiteflies of the Bemisia tabaci complex. Control is based essentially on intensive insecticide applications against the insect vector but is largely ineffective. No virus-resistant or tolerant commercial tomato cultivars are available. Recently, a B. tabaci-resistant tomato line based on the introgression of type IV leaf glandular trichomes and secretion of acylsucroses from the wild tomato Solanum pimpinellifolium was shown to effectively control the spread of tomato yellow leaf curl virus, a begomovirus (genus Begomovirus, family Geminiviridae) persistently transmitted by B. tabaci. As short acquisition and transmission periods are associated to the semipersistent transmission of ToCV, its possible control by means of the B. tabaci-resistant tomato could be compromised. Moreover, if the antixenosis effect of the resistance trait present in those tomato plants results in increased B. tabaci mobility, an increased ToCV spread might even occur. We demonstrated, however, that the use of acylsugar-producing B. tabaci-resistant tomatoes effectively controls ToCV spread compared to a near-isogenic line without type IV trichomes and acylsugar secretion. No increase in the primary ToCV spread is observed, and secondary spread could be reduced significantly decreasing the incidence of this virus. The possible use of host plant resistance to whiteflies to limit spread of ToCV opens up new alternatives for a more effective control of this virus to reduce the damage caused in tomato crops.

番茄萎黄病毒（属 鼻病毒，家人 梭状病毒科）（ToCV）迅速出现，对全球番茄生产造成的损害增加。该病毒以半永久性方式由几种粉虱（Hemiptera：Aleyrodidae）物种传播，并且正在扩大与该粉虱的粉虱的出现有关的地理和宿主范围。烟粉虱复杂。防治基本上是基于对昆虫媒介的大量杀虫剂施用，但在很大程度上是无效的。没有可用的抗病毒或耐商业番茄品种。最近，烟粉虱IV型叶腺毛状体渗入和野生番茄中酰基糖分泌的抗性番茄 平果龙葵 被证明可以有效控制番茄黄叶卷曲病毒（一种begomovirus（属 乙状病毒，家人 双子病毒科） 烟粉虱。由于较短的采集和传输周期与ToCV的半持久传输相关联，因此可以通过烟粉虱抗性番茄可能会受损。此外，如果那些番茄植物中存在的抗性状的抗异种作用导致烟粉虱流动性，甚至可能会出现ToCV传播增加的情况。但是，我们证明了使用酰基糖生产烟粉虱与没有IV型毛状体和酰基糖分泌的近等基因系相比，抗性番茄可有效控制ToCV传播。没有观察到主要ToCV传播的增加，可以减少次要传播，从而大大降低了该病毒的发病率。可能利用寄主植物对粉虱的抗性来限制ToCV的传播，开辟了新的替代方法，可以更有效地控制该病毒，从而减少对番茄作物造成的损害。
