近年来，番茄褪绿病毒（ToCV）和葫芦黄化病毒（CCYV）在世界范围内迅速传播，对蔬菜生产造成严重影响，引起了人们的广泛关注。这两种病毒都是由甘薯粉虱，烟粉虱（Gennadius），以半持久性的方式传播。海南省是我国的南方省份，至今仍缺乏相关报道。本研究采用观察和实验相结合的方法，探讨了海南省烟粉虱传播的CCYV和ToCV的流行和发病动态。2016年，大量B的番茄和黄瓜植株出现黄化症状。在海南，烟粉虱在番茄和黄瓜上的发病率分别为69.8%和62.6%。经分子鉴定，确定该病毒为Q型，在番茄和黄瓜上的带毒率分别为65.0%和55.0%。番茄和黄瓜附近的喜旱莲子草（Alternanthera philoxeroides）被两种病毒共侵染。此外，ToCV和CCYV的发生动态与海南分布广泛的喜旱莲子草（Alternanthera philoxeroides）关系密切。本研究首次揭示了杂草A.喜旱莲子草同时被ToCV和CCYV感染。烟粉虱对ToCV和CCYV的带毒率较高。海南是我国极其重要的蔬菜生产和育种中心。如果粉虱可以同时携带这两种病毒，那么在它们共同的宿主植物中的共同感染可能在不久的将来导致毁灭性的损失。
In recent years, two of the crinivirus, Tomato chlorosis virus (ToCV) and Cucurbit chlorotic yellows virus (CCYV) have gained increasing attention due to their rapid spread and devastating impacts on vegetable production worldwide. Both of these viruses are transmitted by the sweet potato whitefly, Bemisia tabaci (Gennadius), in a semi-persistent manner. Up to now, there is still lack of report in Hainan, the south of China. We used observational and experimental methods to explore the prevalence and incidence dynamic of CCYV and ToCV transmitted by whiteflies in Hainan of China. In 2016, the chlorosis symptom was observed in the tomato and cucumber plants with a large number of B. tabaci on the infected leaves in Hainan, China, with the incidence rate of 69.8% and 62.6% on tomato and cucumber, respectively. Based on molecular identification, Q biotype was determined with a viruliferous rate of 65.0% and 55.0% on the tomato and cucumber plants, respectively. The weed, Alternanthera philoxeroides near the tomato and cucumber was co-infected by the two viruses. Furthermore, incidence dynamic of ToCV and CCYV showed a close relationship with the weed, Alternanthera philoxeroides, which is widely distributed in Hainan. Our results firstly reveal that the weed, A. philoxeroides is infected by both ToCV and CCYV. Besides, whiteflies showed a high viruliferous rate of ToCV and CCYV. Hainan is an extremely important vegetable production and seed breeding center in China. If the whitefly can carry these two viruses concurrently, co-infection in their mutual host plants can lead to devastating losses in the near future.
