番茄黄化曲叶病毒（TYLCV）是继2003年烟粉虱Q传入中国后，于2006年首次在中国发现的。从那时起，TYLCV在中国番茄田的发病率大大增加，含有细菌共生体Hamiltonella的Q粉虱的丰度和分布也有很高的频率。这表明共生体Hamiltonella可能与烟粉虱传播TYLCV的效率有关。在这里，我们报告的第一个证据表明，汉密尔顿是密切相关的收购，保留，和传播效率的TYLCV的粉虱载体。我们的研究结果结合引入Q后TYLCV的爆发，为中国B的Hamiltonella保持在较高水平提供了解释。烟粉虱Q和对疾病和病媒管理也有影响。
Tomato yellow leaf curl virus (TYLCV) was first detected in China in 2006, following the introduction of Bemisia tabaci Q into China in 2003. Since then, the incidence of TYLCV in tomato fields in China has greatly increased as has the abundance and distribution of Q whiteflies containing the bacterial symbiont Hamiltonella with high frequency. This suggested that the symbiont Hamiltonella might associate with the transmission efficiency of TYLCV by the whitefly vector. Here we report the first evidence that the Hamiltonella is closely associated with the acquisition, retention, and transmission efficiency of TYLCV by the whitefly vector. Our findings combined with the outbreaks of TYLCV following the introduction of Q, provided an explanation for why Hamiltonella is being maintained at a relatively high level in Chinese B. tabaci Q and also have implications for disease and vector management.
