'Candidatus Liberibacter asiaticus'(LIBEAS)

Distribution details in Japan

Situation
Current pest situation evaluated by EPPO on the basis of information dated 2014: Present, restricted distribution
First recorded in: 1988
From CABI Disease map 766 (2012): Present, restricted distribution
Comments
EPPO Reporting Service (524/08) of 1992-06: Ryukyu islands only.

EPPO Reporting Service (2000/105) : at one time thought to be confined to the southern part of the small island of Iriomote. Recent studies show it is present at at least 4 locations on Okinawa, one of the major citrus-producing areas of Japan

EPPO Reporting Service (2006/084) : also in adjacent islands forming part of Kagoshima prefecture, and thus in Kyushu (but not the 'mainland').
