Insects associated with flowering of Rhodomyrtus psidioides (Myrtaceae): Is this a Myrtle Rust (Austropuccinia psidii)-induced Plant-pollinator interaction Extinction Event?

  • The threatened Australian endemic rainforest tree Rhodomyrtus psidioides (Myrtaceae) is visited and pollinated by a taxonomically diverse assemblage of mainly small, ecologically unspecialised, insects. Flower structure suggests that it may also be adapted for wind-pollination. However, the recent (2010) invasion by the aggressive fungal pathogen Myrtle rust (Austropuccinia psidii) has resulted in the local extinction of both the floral resource and associated plant-insect relationships. Here I table observed insect visitors to the flowers of Rhodomyrtus psidioides made before the impact of Myrtle rust - no other records appear to have been published.
