Whiteflies and plant viruses can help each other to speed up biological invasion

...f a group of plant viruses called begomoviruses on crops such as tomato and tobacco. These viruses are transmitted by this whitefly. In many countries and regions, including China, the outbreaks of the B whitefly have also seen the gradual disappearance of some native whitefly biotypes. Many scientists ...
