“…EFSA delivered in September 2018 a renovated database of host plants of Xylella spp., taking into account both species of the genus Xylella (X. fastidiosa and X. taiwanensis) (EFSA, 2018), which was last updated in January 2023 (EFSA, 2023). Raw data and interactive reports were published in Zenodo 1 in the EFSA Knowledge Junction community and in Microstrategy 2 platform, together with a Scientific Report.…”

This scientific report provides an update of the Xylella spp. host plant database, aiming to provide information and scientific support to risk assessors, risk managers and researchers dealing with Xylella spp. Upon a mandate of the European Commission, EFSA created and regularly updates a database of host plant species of Xylella spp. The current mandate covers the period 2021–2026. This report is related to the eighth version of the database published in Zenodo in the EFSA Knowledge Junction community, covering literature published from 1 July 2022 up to 31 December 2022, and recent Europhyt outbreak notifications. Informative data have been extracted from 21 selected publications. Twelve new host plants were identified and added to the database. Nine plant species were reported from Portugal and naturally infected by subsp. multiplex or unknown (i.e. not reported). Three plant species were successfully artificially infected by subsp. fastidiosa. No additional data were retrieved for X. taiwanensis, and no additional STs were identified worldwide. New information on the tolerant/resistant response of plant species to X. fastidiosa infection were added to the database. The overall number of Xylella spp. host plants determined with at least two different detection methods or positive with one method (between sequencing and pure culture isolation) reaches now 433 plant species, 197 genera and 68 families. Such numbers rise to 690 plant species, 306 genera and 88 families if considered regardless of the detection methods applied.

“…We computed the risk of PD using the previously developed climate-driven epidemiological model [29] coupled with the CHELSA dataset [31], which features key climate variables (e.g. temperature and precipitation) at a high spatial resolution of 1 km and daily temporal resolution covering the period 1979-2016.…”

“…We used the model developed in [29], which describes the initial exponential rise (or decrease) of infected plants at the onset of an epidemic based on the spatial distribution of the vector and the bacterial growth and survival processes mediated by temperature. The density of vectors at a given cell controls the number of new plants that will be inoculated with the bacterium, while the local temperature mediates the growth and survival processes of the in-plant bacterial population, leading the initial inoculation to an infection or not.…”

Range shifts in plant disease distributions are sensitive to scaling processes, but few crop case studies have included these predictions under climate change. High-quality wines are increasingly produced in topographically heterogeneous river valleys, whereby disease models that capture steep relief gradients become especially relevant. Here we show how non-linear epidemiological models more accurately reflect the threat of an emerging grapevine pathogen in areas with significant spatial gradients. By comparing the results of simulations using climate data with different spatial resolutions, we identify an increased risk of Pierce’s disease (PD), caused by the vector-borne bacteriumXylella fastidiosa, in wine regions globally. Over 100,000 vine presence records worldwide were analysed with respect to their closer risk-grid cell, observing an increase from 21.8% to 41.2% of the area at risk in European vineyards, from 5.6% to 47.2% in South Africa and to a lesser extent in other wine-growing regions. This general trend has been preceded by an accelerating rate of increase in risk within wine-growing areas. Our analysis demonstrates the importance of microclimatic conditions, highlighting previously unresolved risk zones in areas close to rivers and valleys, and the insufficiency of lower resolution data sets to capture complex climatic variations.

“…This leafhopper is a vector of the destructive bacterial pathogen Xylella fastidiosa , responsible for Pierce's disease in grapevines. Notably, this pathogen has yet to be reported in Canada (Giménez-Romero et al 2022, Dupas et al 2023, Rossi and Rasplus 2023).…”

Climate change has facilitated the introduction, establishment, and movement of invasive species in northern regions, enabling the colonization of previously unsuitable areas. While the responses of insects to these changes have been increasingly studied, our understanding of how such alterations impact trophic interactions still requires further research to make reliable predictions about the spread of diseases in a warming world. Phytoplasmas, a group of obligate parasitic unculturable Mollicutes, primarily rely on leafhoppers (Hemiptera: Cicadellidae) for transmission, spread, and survival. Phytoplasmas are associated with over 600 diseases affecting more than 1,000 plant species, including berries, grapevines, and other small fruits. In North America, diseases such as grapevine yellows, blueberry stunt, and strawberry green petal diseases have been linked to phytoplasma strains transmitted by known leafhopper species. However, the number of phytoplasma diseases has significantly increased in North America over the past decade, suggesting the presence of unidentified vectors or an abundance of leafhopper vectors. This short review provides an overview of the current knowledge on leafhoppers as vectors of phytoplasmas to berries, focusing on the last decade’s research in Canada. This paper also explores the potential implications of climate change on this pathosystem, including the anticipated range expansion of leafhopper species, changes in phytoplasma acquisition and transmission, and the risk of new leafhopper-transmitted plant-pathogen introductions through the arrival of new leafhopper species.
