Vectors as Sentinels: Rising Temperatures Increase the Risk of Xylella fastidiosa Outbreaks

Abstract: Global change is expected to modify the threat posed by pathogens to plants. However, little is known regarding how a changing climate will influence the epidemiology of generalist vector-borne diseases. We developed a high-throughput screening method to test for the presence of a deadly plant pathogen, Xylella fastidiosa, in its insect vectors. Then, using data from a four-year survey in climatically distinct areas of Corsica (France), we demonstrated a positive correlation between the proportion of vectors p… Show more

“…We believe that our results can help designing surveillance plans for Xf that are adapted to the specificities of Corsica. Surveillance may indeed target C. monspeliensis -rich habitats and use Ps sampled there as sentinel insects to track Xf in the environment 5 , 7 . As they highlight an unexpected and unique association pattern between Ps and C. monspeliensis , our results call for more studies on the ecology of Xf vectors in Europe, including common ones, to better understand, anticipate and control the spread of Xf in a climatically changing world.…”

“…C. monspeliensis-dense areas favoring larger populations of Ps and dilution over the resource may have contributed to the spread of Xf over Corsica 5,7 . Indeed, C. monspeliensis can be infected by Xf 63,64 and is very abundant in early stages of mesomediterranean vegetation series in Corsica 39 .…”

“…Corsica as a whole is considered infected by the bacterium (European Commission, 2022), but Xf detections are not homogeneously distributed across the island (Figure 1). Our sampling scheme was therefore driven by all existing data on Xf on the island: (1) data on official detection of Xf in plants retrieved from the Plateforme ESV (https://plateforme-esv.fr/; Project PESV‐DATA4R‐XXXX; link to dataset: https://doi.org/10.15454/RWBIWD) and (2) the data presented in Farigoule et al (2022). Eighty‐seven cicadas were collected in buffer zones of 5 km around officially detected Xf foci (data source 1), 45 in buffer zones around Xf foci reported in Farigoule et al (2022), 24 in sites meeting these two conditions and 61 in sites meeting neither of these (Figure 1).…”

The third data source available on the island (Cunty et al, 2020) is also depicted on Figure 1, with the kind permission from the ANSES‐LSV.…”
