• Acizzia acaciaebaileyanae

  Acizzia acaciaebaileyanae is a psyllid species specialized on Acacia baileyana, a widely planted ornamental acacia. Native to Australia, it has spread globally through human transport of its host plant. Despite forming dense populations, it has been observed not to cause visible damage to the host. The species exemplifies inadvertent introduction of specialist herbivores via horticultural trade.

• Acizzia uncatoides

  Acacia Psyllid

  Acizzia uncatoides is a psyllid species native to Australia, primarily associated with Acacia species, especially Acacia melanoxylon, and some Albizia species. It has been introduced to multiple regions worldwide, including La Réunion, where it poses a significant threat to endemic Acacia heterophylla forests. Though capable of reaching high population densities, it is not generally regarded as a major pest species in most of its range. The species serves as prey for generalist psyllid predators and has been targeted for classical biological control programs.
