Since it first was discovered in 2005, the bacterial disease known as citrus greening, or Huanglongbing
(HLB), has devastated millions of acres of crops throughout the U.S.
Dr Sadi explained the disease called Citrus greening or Huanglongbing
disease (yellow dragon disease) is one of the most serious diseases that threatens citrus production in the world.
The Asian citrus psyllid, Diaphorina citri Kuwayama (Hemiptera: Sternorrhyncha: Liviidae), has become one of the main citrus pests worldwide, especially for being a vector of the bacterial disease Huanglongbing
(HLB) (HALBERT and MANJUNATH, 2004).
Candidatus Liberibacter asiaticus (Las) (Rhizobiales: Rhizobiaceae) is a gram-negative, phloem-limited alphaproteobacterium, and the putative causal agent of citrus greening disease, or huanglongbing
Florida, the nation's orange juice engine, has seen the biggest acreage decline as the state has battled Huanglongbing
or citrus greening.
However, the citrus industry in Florida is being severely diminished by a disease called Huanglongbing
(HLB), which also is a major looming threat towards the citrus industry in other citrus-producing states.
citri son deformaciones de brotes y reduccion del tamano de las hojas; aunque el dano mas grave lo ocasiona al ser vector de la bacteria Candidatus Liberibacter, agente causal de la enfermedad conocida como huanglongbing
(HLB) (Bove, 2006; Diaz-Padilla et al., 2014).

First, psyllids cause direct injury to citrus through feeding on phloem juice in immature foliage, deforming the leaves (Halbert and Manjunath 2004); and second, and more importantly, they vector the bacterium Candidatus Liberibacter asiaticus (CLas), which causes the lethal and untreatable citrus disease, huanglongbing
(HLB), also called citrus greening disease.
Citrus greening, or Huanglongbing
(HLB), is a bacterial disease spread by the Asian citrus psyllid.
