Diaphorina citri, the Asian citrus psyllid, is a sap-sucking, hemipteran bug now in the taxonomic family Liviidae. [1] It is one of two confirmed vectors of citrus greening disease . [ 2 ] [ 3 ] It has a wide distribution in southern Asia and has spread to other citrus growing regions.
Citrus greening disease [4] (Chinese: 黃龍病; pinyin: huánglóngbìng abbr. HLB) [5] is a disease of citrus caused by a vector-transmitted pathogen. The causative agents are motile bacteria, Liberibacter spp. The disease is transmitted by the Asian citrus psyllid, Diaphorina citri, and the African citrus psyllid, Trioza erytreae.
Diaphorina is an Old World genus of sap-sucking bugs, typical of the subfamily Diaphorininae. It includes an important pest of citrus : the Asian citrus psyllid, D. citri . Species

It is a parasitoid of the Asian citrus psyllid ( Diaphorina citri ), an economically important pest of citrus crops around the world and a vector for Citrus ...
Citrus greening, also known as huanglongbing, associated with the presence of a bacterium Liberibacter asiaticum, is an example of a plant pathogen that has coevolved with its insect vector, the "Asian citrus psyllid", ACP, Diaphorina citri, such that the pathogen causes little or no harm to the insect, but causes a major disease which can ...
Liberibacter is transmitted by two insects from Psyllidae family – Diaphorina citri in Asia, Brazil and Florida, and Trioza erytreae in Africa. The Asian HLB strain, "Candidatus Liberibacter asiaticus" is more heat tolerant, while the African strain, Candidatus Liberibacter africanus is asymptomatic at temperatures above 30 °C. [3]
Trioza erytreae, the African citrus psyllid, is a sap-sucking insect, a hemipteran bug in the family Triozidae. It is an important pest of citrus, being one of only two known vectors of the serious citrus disease, huanglongbing or citrus greening disease. It is widely distributed in Africa. The other vector is the Asian citrus psyllid ...
