The Asian citrus psyllid, Diaphorina citri (Hemiptera: Psyllidae), is a tiny (1/8 inch, 3 mm in length) mottled brown insect that is about the size of an aphid. It attacks citrus and very closely related ornamental plants in the family Rutaceae (mock orange, Indian curry leaf, orange jasmine and other Murraya species). This pest attacks new citrus leaf growth and, because of the salivary toxin that it injects, causes the new leaf tips to twist or burn back. However, the more serious damage that it causes is vectoring the bacteria (Candidatus Liberibacter asiaticus and related species) that cause Huanglongbing (HLB or citrus greening) disease. Huanglongbing causes shoots to yellow, assymetrical leaf mottling, and abnormally shaped fruit with bitter juice. The disease can kill a citrus tree within 3 to 5 years.
