Distribution details in Italy

Current pest situation evaluated by EPPO on the basis of information dated 2014: Present, restricted distribution
From CABI Disease map 289 (1998): Present, no details
Sicilia and Calabria.

EPPO Reporting Service 465 of 1986-07.

EPPO Reporting Service (95/201) provides an update on the situation. Only 78 plants were found infected, and these were destroyed. Surveys in Calabria since 1986 have given consistently negative results. Italy is classed as an EU Protected Zone for CTV (European isolates) and has surveyed its whole territory to justify this. Accordingly, the situation in Italy can be regarded as "found but not established".

EPPO Reporting Service (2003/071) : in 2002, a new large outbreak (10000 trees) found in the region of Siracusa (Sicilia). Probably derived from illegally imported budwood.

EPPO Reporting Service (2005/089) : 3 separate outbreaks now known - in Siracusa province (Sicilia), in Taranto province (Puglia), in Catania province (Sicilia). Mild isolates in the first two cases (similar by molecular tests to an isolate from Spain), but severe in the third (similar in molecular tests to isolates from USA and Japan). Considered as evidence of two separate introductions.

EPPO Reporting Service (2006/182) : outbreak in Calabria. Present situation is outbreaks in Puglia (province of Taranto), Calabria (province of Reggio di Calabria), Sicilia (provinces of Siracusa and Catania); under official control.

EPPO Reporting Service (2011/003) : update on the outbreak in Calabria (detected in 3 orchards in Cosenza, 3 orchards in Vibo Valentia, 12 orchards in Reggio Calabria, isolated findings in 2 nurseries).
