Huanglongbing: possível ameaça à citricultura catarinense?

Agropecuária Catarinense, 2017
Resumo - O Huanglongbing (HLB) é a principal doença dos citros no Brasil. É causado por bactérias do gênero “Candidatus Liberibacter” e transmitido pelo psilídeo-asiático-dos-citros, Diaphorina citri. Os sintomas do HLB são mosqueamento nas folhas (clorose assimétrica no limbo) e amarelecimento de ramos, além de os frutos mostrarem maturação irregular,

Attractiveness of host plant volatile extracts to the Asian citrus psyllid, diaphorina citri, is reduced by terpenoids from the non-host cashew [PDF]

, 2018
Diaphorina citri is a vector of the bacterial causative agent of Huanglongbing (HLB = Citrus greening), a severe disease affecting citrus crops. As there is no known control for HLB, manipulating insect behaviour through deployment of semiochemicals ...

Neuropeptide Ecdysis‐Triggering Hormone and Its Receptor Mediate the Fecundity Improvement of ‘Candidatus Liberibacter Asiaticus’‐Infected Diaphorina citri Females and CLas Proliferation

Advanced Science, Volume 12, Issue 18, May 15, 2025.
In CLas‐infected D. citri, CLas lowers 20E levels initially, relieving the suppression of ETH release. The subsequent increase in ETH levels upregulates its receptor DcETHR and activates the JH signaling pathway. The signaling cascade of 20E‐ETH/ETHR‐JH along with miR‐210, targeting DcETHR, boost female fecundity in CLas+ D.

Huanglongbing (HLB; Citrus Greening) and Nutrient Deficiency Identification

EDIS, 2019
Huanglongbing (HLB) is a bacterial disease that is spread by an insect, the Asian citrus psyllid. This 2-page fact sheet is a minor revision that explains how to tell the difference between HLB symptoms and symptoms from nutrient deficiencies.

The Potato StNAC2‐StSABP2 Module Enhanced Resistance to Phytophthora infestans Through Activating the Salicylic Acid Pathway

Molecular Plant Pathology, Volume 26, Issue 5, May 2025.
The transcription factor StNAC2 upregulated the expression of StSABP2, encoding a protein that converts methyl salicylate (MeSA) into SA, activating the SA signalling pathway and enhancing resistance to Phytophthora infestans. ABSTRACT Potato late blight is an important disease in potato production, which causes serious damage. Salicylic acid (SA) is a

In vitro culture of the fastidious bacteria Candidatus Liberibacter asiaticus in association with insect feeder cells [PDF]

, 2011
Ca. Liberibacter asiaticus (LAS) is vectored by psyllids and is able to proliferate inside the insect. We therefore hypothesize that insect cells could act like feeder cells, providing nutrients in a continuous way and a favorable environment to the ...
