This webinar series continues the inspiring path of the Xylella Files organised previously by the UC Berkeley and Auburn University groups, with the aim to provide a platform for informal exchanges and interactions on the state of the art of research and control on the epidemics caused by Xylella fastidiosa worldwide.

Organised jointly by the EU funded BeXyl project, EFSA (European Food Safety Authority) and Auburn University, this webinar will be the first in a series exploring the epidemics of Xylella fastidiosa in Salento (Italy).

  • Title: Epidemics of Xylella fastidiosa in Salento (Italy): the current status
  • Presenter: Dr. Donato Boscia (CNR-ISPP Bari, Italy)
  • Time: 18.00 CET (Central European Time) on Tuesday, 13 February 2024 (4.00am Wednesday, 14 February 2024 AEDT)

Since the emergency in 2013 of the epidemic of Xylella fastidiosa affecting the olive industry of the Salento peninsula (southern Italy), nearly 40% of the territory of the Apulia region has been included by the phytosanitary authorities in the demarcated “infected area”, where several containment measures are strongly recommended and few are mandatory (i.e. banning plantations of highly susceptible species).

Such status coupled with favorable epidemiological conditions caused the persistence of the infections in the whole area, decimating millions of olive trees, the main crop and landscape species of the area. Most likely, the wide occurrence of deadly infections entails a reduction of the reservoirs of bacterial inoculum and infective insect vectors.

In the last two-three years an increasing number of reports of symptoms remittance in trees not severely affected has been recorded, posing new complex questions to the scientific community. Initial investigations on recently isolated strains seem to exclude the insurgence of adaptive traits and loss of aggressiveness. While preliminary data on the evolution of the vector infectivity showed a decreasing trend, probably resulting in a reduction of the superinfections events on the surviving trees.
