Host plants of Xylella fastidiosa
EFSA has recently published an update of its database on host plants of Xylella fastidiosa (EPPO A2 List). The overall number of host plants naturally infected by Xylella spp. and determined with at least two different detection methods, or positive with either sequencing or pure culture isolation reaches 451 plant species,204 genera and 70 families. When considering plant species artificially infected or infected in unspecified conditions, this number reached 712 species.
The following plant species have been newly added to the EFSA database as hosts of X. fastidiosa:
- Adenocarpus sp. (Fabaceae)
- Ailanthus altissima (Simaroubaceae)
- Carpinus caroliniana (Betulaceae)
- Celtis sp. (Ulmaceae)
- Cistus ladanifer (Cistaceae)
- Coleonema album (Rutaceae)
- Cytisus multiflorus (Fabaceae)
- Cytisus striatus (Fabaceae)
- Echinospartum lusitanicum (Fabaceae)
- Halimium calycinum (Cistaceae)
- Halimium lasianthum (Cistaceae)
- Halimium ocymoides (Cistaceae)
- Halimium sp. (Cistaceae)
- Prunus campanulata (Rosaceae)
- Quercus prinus (Fagaceae)
- Salix atrocinerea (Salicaceae)
Host plant records (resulting from natural infection) have been transferred to the EPPO Global Database.
