A biocontrol technique to manage invasive exotic plants is an attractive option, especially if the parasite to the exotic host is already native to the country. In China, a native dodder is being studied for use against beggar-ticks (Bidens pilosa), a plant native to the Americas but invasive in Asia. Young Bidens plants colonized by dodder suffer due to a reduction in their ability to produce defensive compounds and may not survive. Progressively older plants were less affected and would not likely be managed by the dodder.
