Huanglongbing (HLB) is the most destructive citrus pathosystem worldwide. Previously known primarily from Asia and Africa, it was introduced into the Western Hemisphere in 2004. All infected commercial citrus industries continue to decline owing to inadequate current control methods. HLB increase and regional spatial spread, related to vector populations, are rapid compared with other arboreal pathosystems. Disease dynamics result from multiple simultaneous spatial processes, suggesting that…

Biology and management of Asian citrus psyllid, vector of the huanglongbing pathogens.

Recent advances in the understanding of D. citri biology and behavior, pathogen transmission biology, biological control, and chemical control with respect to "Candidatus Liberibacter asiaticus" are discussed.

Status of Huanglongbing (HLB) outbreaks in Florida, California and Texas

Based on the Florida experience, Texas proactively controlled the vector by implementing area-wide management and disease spread was slower than in Florida, however, they also did not remove infected trees, so there was no chance of controlling the epidemic.

Citrus huanglongbing: a newly relevant disease presents unprecedented challenges.

This review focuses on the most recent research on citrus, 'Candidatus Liberibacter asiaticus', and psyllid interactions, specifically considering the following topics: evolutionary relationships among 'Ca. Liberibacteria' spp.

Huanglongbing: An overview of a complex pathosystem ravaging the world's citrus.

This review is intended to provide an overview of the importance of HLB to a wider audience of plant biologists and recent advances on host-pathogen interactions, population genetics and vectoring of the causal agent are discussed.

Candidatus Liberibacter asiaticus: virulence traits and control strategies

This review is not intended to be comprehensive and focuses on the virulence factors of Ca.

Molecular signatures between citrus and Candidatus Liberibacter asiaticus

This review of the recent progress in genomic research on the pathogen, the interaction of host and CLas, and the influence of CLas infection on the transcripts, proteins, and metabolism of the host proposes potentially promising areas for mechanistic studies of CL as pathogenicity, defense regulators, and genetic improvement for HLB tolerance/resistance in the future.

Long-Term Field Evaluation Reveals Huanglongbing Resistance in Citrus Relatives.

Disease resistance/tolerance was observed in Australian citrus relative genera Eremocitrus and Microcitrus, which are sexually compatible with citrus and may be useful in future breeding trials to impart HLB resistance to cultivated citrus.

Alleviation of Huanglongbing disease in citrus by foliar application of microelements

Huanglongbing (HLB), also referred to as citrus greening disease, ranks high among the most destructive diseases in citrus plants worldwide. This disease is caused by the Gram-negative bacterium…

Presence and distribution of the African citrus psyllid in São Tomé island

Up‐to‐date occurrence data on the presence of T. erytreae throughout the isle of São Tomé is provided and the identity of the captured adults was assessed and confirmed through molecular identification by sequencing a portion of the mitochondrial COI.

Overview of citrus huanglongbing spread and management strategies in Brazil

The management of HLB in São Paulo and Triângulo/Sudoeste Mineiro citrus belt has been considered a success case and has ensured the maintenance of citrus production and competitiveness of the Brazilian citrus industry while new, more durable, and sustainable measures are not yet available.

Citrus Huanglongbing: Review, Present status and Future Strategies

The recent arrival of the vectors in citrus producing areas previously regarded as HLB-free highlights the potential threat of one of the most serious diseases of citrus, thus emphasizing the need for effective quarantine services.

Detection of 'Candidatus Liberibacter asiaticus' in Diaphorina citri and its importance in the management of citrus huanglongbing in Florida.

The study suggests that discount garden centers and retail nurseries may have played a significant role in the widespread distribution of psyllids and plants carrying HLB pathogens in Florida.

Effect of strategies for inoculum reduction and vector control on Huanglongbing progress

It is necessary to evaluate the effectiveness of both strategies on the HLB epidemics with regard to the frequency of their application and their yearly and multiyear costs.

Effects of huanglongbing on fruit quality of sweet orange cultivars in Brazil

Effect of HLB on fruit quality of the most important sweet orange cultivars grown in São Paulo State was less pronounced on early and mid season sweetorange cultivars than on late season cv.

Citrus Huanglongbing: the pathogen and its impact.

The author presents a concise compilation of the main features and symptoms of the disease, the causal organisms and the vectors including impacts for Florida and Brazil, two relatively new areas where the disease has been discovered, as well as implications for California, Texas, and Arizona citrus industries.

10.5 An approach to model the impact of Huanglongbing on citrus yield

Citrus huanglongbing (HLB) is the most serious disease of citrus worldwide because once a tree is infected there is no cure and its yield is greatly compromised while the disease spreads all over the…

Concepts in Huanglongbing Epidemiology

Combined interpretations of spatial analyses indicate two spatial mechanisms of vector spread of HLB, within local areas and over longer distances, which are interpreted as indicative of the presence of secondary foci that are quite prevalent and are at a distance of about 25-50 m from the main cluster of disease and each other.

DISTRIBUTION OF THE ASIAN CITRUS PSYLLID, DIAPHORINA CITRI KUWAYAMA (RHYNCHOTA: PSYLLIDAE) IN THE CARIBBEAN BASIN

The distribution of D. citri in the Caribbean Basin is documented to show that it can move on fresh, unprocessed citrus fruit and that its introduction occurred at least one year before its detection.

The Economics of Living with Citrus Diseases: Huanglongbing (Greening) in Thailand

This paper reports on the financial impact to farmers and their countries by HLB and suggests ways in which these losses can be minimized through programs of certification and education; and by the application of methods for disease control which are now standard practices in other citrus-growing countries throughout the world.

Preliminary Analysis of Citrus Greening (Huanglungbin) Epidemics in the People's Republic of China and French Reunion Island
