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.<h4>Methods</h4>We used observational and experimental methods to explore the prevalence and incidence dynamic of CCYV and ToCV transmitted by whiteflies in Hainan of China.<h4>Results</h4>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 incVirology journalDetection and epidemic dynamic of ToCV and CCYV with Bemisia tabaci and weed in Hainan of China.PMC5584531CARS-25-B-0531501643, 31571982 and 31571981201303028Liu YZhang DZhang YLi FZhou XShi XTang XYan FfalseDetection and epidemic dynamic of ToCV and CCYV with Bemisia tabaci and weed in Hainan of China.<h4>Background</h4>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.
