Abstract: Chromolaena odorata, native to Central and South America, is a worldwide perennial invasive alien weed. It has spread into most of the humid tropical and subtropical regions of Africa, Asia, Oceania and Micronesia. Moreover, C. odorata continues to spread rapidly, posing a serious threat to crops, forestry, indigenous vegetation and biodiversity conservation. It has captured extensive attention because of its serious impacts on environment and socioeconomic development. In order to restrict its range expansion and eliminate its adverse impacts, it is necessary to elucidate the mechanisms underlying successful invasion of C. odorata, for which introduction status and invasion routes should be known. We reviewed the research on this weed, including its biological characteristics, geographic distribution, invasion consequences and control, especially its introductions, invasion routes throughout the world and mechanisms of successful invasion. We presented prospects for research on the ecophysiology and molecular biology of C. odorata, emphasizing that study of the genetic basis of adaptive evolution may facilitate elucidating mechanisms underlying its successful invasion.
