Standardized Protocol for Isolation and Cryopreservation of Cultivable Endophytes From Fresh and Dried Citrus aurantium Peels

Food Safety and Health, EarlyView.
A protocol for converting Citrus aurantium peel—from both fresh fruit and dried Zhike—into a curated endophytic microbial library through standardized surface sterilization, tissue homogenization, and multi‐medium culturing, followed by 16S/ITS‐based identification and −80°C cryopreservation, enabling reproducible exploration of citrus peel microbiota ...

A review of techniques for detecting Huanglongbing (greening) in citrus [PDF]

Canadian Journal of Microbiology, 2016
Huanglongbing (HLB) is the most destructive disease of citrus worldwide. Monitoring of health and detection of diseases in trees is critical for sustainable agriculture. HLB symptoms are virtually the same wherever the disease occurs. The disease is caused by Candidatus Liberibacter spp., vectored by the psyllids Diaphorina citri Kuwayama and Trioza ...

Modeling huanglongbing transmission within a citrus tree [PDF]

Proceedings of the National Academy of Sciences, 2012
The citrus disease huanglongbing (HLB), associated with an uncultured bacterial pathogen, is threatening the citrus industry worldwide. A mathematical model of the transmission of HLB between its psyllid vector and citrus host has been developed to characterize the dynamics of the vector and disease development, focusing on the spread of the pathogen ...

Rootstock impacts on citrus flush dynamics, vegetative growth, and Diaphorina citri infestation and dispersion: Implications for huanglongbing management

Pest Management Science, EarlyView.
Dwarfing citrus rootstocks restrict flush shoot growth on the scion, thereby reducing Asian citrus psyllid infestation, dispersal, and huanglongbing (HLB) progression. These findings support the use of dwarfing rootstocks as an effective cultural strategy in integrated HLB management for citrus orchards.

Prey Range and Voracity of Main Insect Natural Enemies of Pests in Corsican Clementine Orchards

Entomologia Experimentalis et Applicata, EarlyView.
To assess the biocontrol potential on the main arthropod pests of clementine orchards in Corsica, laboratory experiments were carried out using five potential predators. Their prey range and voracity were tested on three pest species. Then, a global predation rate index was calculated at the scale of the entire community of insect predators.

Low Rates of Kaolin in Different Application Periods Reduce Diaphorina citri Population and Huanglongbing Incidence in Commercial Citrus Orchards

Journal of Applied Entomology, EarlyView.
ABSTRACT Huanglongbing (HLB) is the most destructive citrus disease worldwide, and it has been disseminated by the Asian citrus psyllid Diaphorina citri, the vector of the causing agent Candidatus Liberibacter asiaticus. Although processed kaolin reduces psyllid infestation, long‐term field data from commercial orchards are limited.

Peptide conjugated morpholinos for management of the huanglongbing pathosystem

Pest Management Science, 2020
AbstractBACKGROUND‘Candidatus Liberibacter asiaticus’ (CLas) is the causal agent of the devastating citrus disease Huanglongbing (HLB) and is transmitted by the insect vector Diaphorina citri (Hemiptera: Liviidae). A potential approach for treating CLas infection is the use of synthetic nucleic acid‐like oligomers to silence bacterial gene expression ...

A Systematic Map to Identify Knowledge Gaps on a Vector of Citrus Greening Diseases: The African Citrus Triozid, Trioza erytreae (Del Guercio, 1918) (Hemiptera: Triozidae)

Journal of Applied Entomology, EarlyView.
ABSTRACT Globally, citrus production areas are threatened by greening diseases, also known as Huánglóngbíng (HLB), associated with phloem‐limited gram‐negative species of the genus Candidatus Liberibacter. Those pathogens are transmitted by either the Asian citrus psyllid, Diaphorina citri Kuwayama 1908 (Hemiptera: Psyllidae), or the African citrus ...

A Non‐Host Pathogen Elicitor Induces Blast Resistance Mediated by OsNAC78‐Pir7b Module in Rice

Plant, Cell &Environment, EarlyView.
ABSTRACT Plants exhibit broad‐spectrum and persistent resistance induced by non‐host pathogens. Previous studies have found that syringolin A secreted by Pseudomonas syringae pv. syringae can activate the expression of defense‐related gene Pir7b in non‐host rice, but the underlying mechanism remains ambiguous.

Molecular evidence for the presence of huanglongbing in Pakistan [PDF]

Australasian Plant Disease Notes, 2007
The presence of Candidatus Liberibacter asiaticus in citrus orchards in the North-West Frontier Province of Pakistan has been confirmed. Samples of DNA extracted from leaves of putatively infected citrus plants and from the vector of the disease, Diaphorina citri, were subjected to analysis using PCR and produced DNA amplicons characteristic of this ...
