[Progress in studies on an exotic vicious weed Mikania micrantha]

Mikania micrantha is a perennial weed of Astraceae native to south and central America. It has invaded Southeast Asia, Pacific region and South China. Because Mikania micrantha grows very fast and is hard to control, it has become one of the world's worst weed. In this paper, the history and status of the study on Mikania micrantha was reviewed. The research on Mikania micrantha was mainly focused on its biology, ecology, harm and control. Although some progress in the research was obtained, there is no dramatic breakthrough in the control of Mikania micrantha so far. There fore, it needs more work to solve the problems resulted from the invading Mikania micrantha.
