  • A moth Lathronympha strigana which primarily feeds on the seeds but also on tutsan leaf tips and inside stems, and a leaf-feeding beetle (Chrysolina abchasica) were tested and found to be sufficiently host specific and not a risk to native plant species. (wikipedia.org)
  • When established, tutsan can be dangerous because it is very difficult to remove and is very unpalatable to both native and introduced herbivores. (wikipedia.org)
