Abstract:
... Citrus Huanglongbing (HLB, also known as “citrus greening”), an important disease worldwide, is associated with three species of phloem-limited Candidatus liberibacter, of which Candidatus L. asiaticus (CLas) is the predominant one that has severely affected citrus production. TaqMan real-time polymerase chain reaction (PCR) (TM) has been the standard and very efficient method to diagnose several ...

Abstract:
... The black curry leaf psyllid, Diaphorina communis, is a host of the citrus pathogen, ‘Candidatus Liberibacter asiaticus’ (‘CLas’). However, there is a paucity of information on its biology; hence, this study was conducted to evaluate survival and development on citrus, in this instance mandarin (Citrus reticulata) and curry leaf (Bergera koenigii), and transmission of ‘CLas’. Given its similarity ...
