Trioza erytreae, the African citrus psyllid, is a sap-sucking insect, a hemipteran bug in the family Triozidae.

[1] The citrus psyllid is found in Cameroon, Comoros, the Congo, Eswatini, Ethiopia, Kenya, Madagascar, Malawi, Mauritius, Réunion, Rwanda, South Africa, St. Helena, Sudan, Tanzania, Uganda, Zambia, and Zimbabwe.

It typically adopts a distinctive stance when feeding, with head down sucking sap and body raised at an angle of about 35°.

[5] Trioza erytreae is one of only two vectors of the causative agents of citrus greening disease, the phloem-restricted, Gram-negative bacterium Candidatus Liberibacter spp.

The major secondary hyperparasitoid is Aphidencyrtus cassatus, which was recorded in large numbers and which attacks both of the primary parasitoids.
