In this study，we monitored the carrying rate of ToCV of Bemisia tabaci in major tomato
production areas of China in 2013 and 2014．We discovered that in 2013，among all B. tabaci samples collected
from 16 different areas of China，those from Yuncheng Shanxi，Taiyuan Shanxi，Shanghe Shandong，Yangling
Shaanxi，Haidian Beijing carried ToCV，but the virus carrying rates were all below 20%．In 2014，among B. tabaci collected from 17 areas，those from Haidian Beijing，Hangzhou Zhejiang，Shanghe Shandong，
Yuncheng Shanxi，Yangling Shaanxi，and Inner Mongolia were infected by ToCV．The virus carrying rates，
except Beijing，were all above 50%．ToCV was reported for the first time in Shanxi，Shaanxi，Zhejiang and
Inner Mongolia，and the rate of ToCV-infected B. tabaci increased significantly in 2014，compared with that in
2013．Thus，high attention should be paid to the trend of ToCV rapid diffusion in China.
