Population Dynamics of the Invasive Psyllid Acizzia uncatoides on Acacia heterophylla in Relation to Host Phenology, and climate (Aspirator Sampling, La Réunion, 2017-2022)

This dataset supports the study of the population dynamics of the invasive psyllid Acizzia uncatoides (Ferris & Klyver) on its endemic host plant, Acacia heterophylla Willd., in the high-elevation forests of La Réunion Island. Following its introduction in 2010, this phloem-feeding insect has threatened the ecological integrity of the "Tamarin des Hauts" forests. This monitoring program (2017–2022) establishes a pre-release baseline for classical biological control, characterizing how climate (temperature, rainfall) and plant phenology (resource pulses) drive psyllid outbreaks along an elevational gradient.
