Acizzia uncatoides
(Ferris & Klyver, 1932)
Acacia Psyllid
Acizzia uncatoides is a to Australia, primarily associated with Acacia species, especially Acacia melanoxylon, and some Albizia species. It has been to multiple regions worldwide, including La Réunion, where it poses a significant threat to Acacia heterophylla forests. Though capable of reaching high , it is not generally regarded as a major in most of its range. The species serves as for psyllid and has been targeted for programs.

Habitat
Associated with Acacia and Albizia plants; in its range, occupies Australian where these leguminous trees occur. In invaded regions, found in highland forests of La Réunion dominated by Acacia heterophylla, as well as in various environments where planted or naturalized Acacia occur.
Distribution
to Australia; and established in multiple parts of the world including La Réunion (Indian Ocean) and the Azores (Portugal: Flores, Graciosa, Pico, Santa Maria, Terceira islands). Distribution closely tracks that of its Acacia and Albizia plants.
Diet
Phloem-feeding on Acacia , with strong preference for Acacia melanoxylon; also feeds on some Albizia species.
Host Associations
- Acacia melanoxylon - primary especially favored
- Acacia heterophylla - in La Réunion, subject to concern
- Albizia - some
Ecological Role
that can reach high on plants; serves as for . In La Réunion, its proliferation threatens Acacia heterophylla forest , prompting intervention.
Human Relevance
Not generally regarded as a in most regions, though capable of proliferating to high numbers. In La Réunion, considered a critical threat to highland forests, motivating efforts using the Harmonia conformis. to new regions presumably with material.
Similar Taxa
- Other Acizzia species share similar associations with Acacia; specific identification requires detailed morphological examination not covered in available sources.
- Other psyllid species on AcaciaMultiple utilize Acacia; A. uncatoides distinguished by preference patterns and presumably morphological characters.

Biological Control Context
In La Réunion, A. uncatoides invasion threatens the Acacia heterophylla, prompting evaluation of Harmonia conformis as a agent. Risk assessment indicates manageable environmental risk due to climatic segregation between the and vulnerable resident .
