The susceptibility of olive cultivars to Xylella fastidiosa subsp. pauca ST53 affects transmission efficiency of the insect vector Philaenus spumarius (Hemiptera: Aphrophoridae)
BACKGROUND Olive quick decline syndrome (OQDS), caused by Xylella fastidiosa subsp. pauca ST53, has devastated olive groves in Apulia (southern Italy), severely impacting olive production and rural agroecosystems. High populations of the key insect...
Confirmation of Xylella fastidiosa (Lysobacterales: Lysobacteraceae) transmission by 8 leafhopper species present in coffee plantations in Costa Rica
Xylella fastidiosa Wells et al. 1987 is a vector-transmitted plant pathogen of economic importance that is widespread throughout coffee plantations in Costa Rica. Previous studies have shown the existence of a broad diversity of leafhoppers present in different coffee...
Emerging risk of Xylella fastidiosa in Europe under global change
The insect-borne bacterium Xylella fastidiosa is one of the most damaging plant pathogens affecting perennial crops in Europe since its first detection in 2013. Although its spread has remained geographically constrained, recent outbreaks and surveillance data suggest...
First Report of Xylella fastidiosa Infection and Pierce’s Disease in Resistant Grape Cultivars in Texas, United States
All commercially cultivated European grapevines (Vitis vinifera) are considered susceptible to Pierces disease (PD) caused by the xylem-limited bacterium Xylella fastidiosa (Wilcox et al. 2015). PD causes vine losses and is the primary limiting factor to grape...
Complete Genome Sequence Data of Two Xylella fastidiosa subsp. multiplex Strains (ST26) Isolated from Infected Almond and Cherry in Southern Italy
In the framework of the monitoring campaign annually carried out in the Apulia region (southern Italy) to tackle the epidemic of X. fastidiosa subsp. pauca decimating olive trees, an outbreak of Xylella fastidiosa subsp. multiplex was discovered in 2024 with almond...
Physiologically-based eco-epidemiological model of Xylella fastidiosa infection in olive groves
Aggressiveness of Subspecies and STs of Xylella fastidiosa and Plant Response in Nicotiana benthamiana
The aggressiveness of seventeen X. fastidiosa strains, representing different subspecies and sequence types (STs), was studied in the surrogated host N. benthamiana by the analysis of the population levels and symptoms dynamics, dose-response relationships and the...
