Abstract
AbstractThe Asian citrus psyllid,Diaphorina citri, is a vector of ‘CandidatusLiberibacter asiaticus’ (CLas), a gram-negative, obligate biotroph whose infection inCitrusspecies is associated with citrus greening disease, or Huanglongbing (HLB). Strategies to blockCLas transmission byD. citriremain the best way to prevent the spread of the disease into new citrus growing regions. However, identifying control strategies to block HLB transmission poses significant challenges, such as the discovery a

Abstract
Huanglongbing, or citrus greening disease, is the most serious disease of citrus worldwide and is associated with plant infection by ‘Candidatus Liberibacter asiaticus’ (CLas) and other Liberibacter species. CLas is transmitted by Diaphorina citri, the Asian citrus psyllid, in a circulative propagative manner. Circulative propagative transmission is a complex process comprising at least three steps: movement of the pathogen into vector tissues, translocation and replication of the pathogen with
