Maximum Likelihood tree (5,000 bootstrap replicates) developed to confirm species identifications and assess the genetic variation in the sequence of mitochondrial cytochrome oxidase, subunit I (COI) between ACP and other Australian native and exotic psyllids sequenced in this study. Bootstrap values < 50% are not reported. The target species, D. citri, is indicated in bold at the top of the tree, distinct from the other taxa. The scale bar is a genetic distance of 5%. All COI sequences were generated in this study, GenBank accession numbers are indicated together with the VAITC database identification number.
