Pacific Pests, Pathogens and Weeds


  • Probably widespread through introduction. A beetle used in biocontrol of Sida, e.g., Sida acuta and Sida rhombifolia (common wireweed & Paddy's lucerne) causing severe defoliation.  
  • Native of Mexico. Introduced into Australia, Fiji, Papua New Guinea, Vanuatu. Present in New Caledonia.
  • Eggs laid on Sida, larvae remain together until last moult, adults brown then bright green with black markings. Adults spread on the wing.
  • Biosecurity: need to test potential harm to native Sida (and other) species before release.
  • Survival affected by condition of Sida; poor in dry seasons, needing reintroductions.
  • Collect in wet season (at least 50); release together; check after 2-3 weeks for eggs/larvae, and later adults. Distribute further when beetles established over several square metres.
