双生病毒引起的病害在最近20年间由局部发生的小病害衍变成目前全球性的最重要的植物病毒病害之一,危害玉米、小麦、棉花、木薯、番茄等重要作物和观赏植物,仅木薯每年在全球造成的经济损失就达数十亿美元之巨。同时双生病毒的介体昆虫烟粉虱在此期间发展成为重要的全球性害虫。前期的生态学研究结果发现,双生病毒可以通过抑制作物的抗虫反应,从而促进了烟粉虱种群的增长;烟粉虱的种群增长反过来促进了双生病毒在全球范围内的 The disease caused by gemini has been evolved from a small local disease to one of the most important plant virus diseases in the world in the recent 20 years and endangered the important crops and ornamental plants such as corn, wheat, cotton, cassava and tomato. Only cassava The global economic loss each year amounts to billions of dollars. Simultaneously, the geminivirus mediator insects, Bemisia tabaci, developed into an important global pest during this period. The results of previous studies on ecology showed that geminiviruses promoted the population growth of Bemisia tabaci by restraining the insect-resistant reaction of crops. The population growth of Bemisia tabaci promoted conidiospheric viruses in the world
