Name: African citrus psyllid, Trioza erytreae
The main economic importance of T. erytreae is that it is the vector of the very serious citrus huanglongbing disease caused by Liberibacter species. While the insect itself is a minor citrus pest, huanglongbing is a serious threat to citrus-producing areas worldwide.
The African citrus psyllid, Asiatic citrus psyllid and huanglongbing disease are not known to occur in Australia. If these pests become established in Australia, they have the potential to cause major crop losses and any farm/orchard infested can be quarantined. All citrus cultivars are a host for African citrus psyllids (e.g. orange, lemon, lime, grapefruit, mandarin, cumquat, tangelo, pomelo, native citrus and citrus rootstock). Native and exotic mock orange/orange jasmine (Murraya spp.), white ironwood (Vepris lanceolata), lime berry (Triphasia trifolia) and horsewood (Clausena anisata) are also hosts.T. erytreae affects other species in the Rutaceae family, and can feed on Cape chestnut (Calodendrum capense), orange-climber or forest-pepper (Toddalia asiatica) and small knobwood (Zanthoxylum capense).
