The European Food Safety Authority (EFSA) updated Xylella spp. host plant database. The report tracks plant species affected by Xylella fastidiosa. The latest update, covering research published between January and June 2024, includes data from 27 scientific publications and recent outbreak notifications.

When using the most stringent methods, the overall number of Xylella spp. host plants reaches now 452 plant species, 204 genera and 70 families. Such numbers rise to 713 plant species, 312 genera and 89 families if considered regardless of the detection methods applied.

One new host plant (Quercus orocantabrica) was identified and added to the database. It was naturally infected by X. fastidiosa subsp. fastidiosa in Portugal. No new sequence types (STs) of Xylella were identified worldwide.
