Melaleuca alternifolia attacked by Trioza melaleucae.
The initial infestation with adult psyllids and very young nymphs (A) can be compared to the final stages of the infestation, with larger 5th instar nymphs causing leaves curling (B). Yearly, M. alternifolia is harvested (left) removing any biomass present above ground (right) (C). Pitting on the leaves are highlighted by arrows (D).

Haplotype network analysis of the samples included in this study, obtained using 33 partial COI DNA sequences.
The Queensland (light green) and the New South Wales (dark green) populations of Trioza melaleucae are compared to populations of T. adventicia from New Zealand (fuchsia), USA (pink) and Australia (purple); T. eugeniae from Australia (blue), T. curta from New Zealand (yellow), T. outeiensis from Taiwan (red) and a Trioza sp. from Queensland (orange). Each mutation is represented by a hatch mark while the size of the circles corresponds to the number of sequences included. Black triangles represent the sequences generated in this study.
