Comments
EPPO Reporting Service (2003/067) : cause of massive oak mortality in Japan. Vectored by Platypus quercivorus.

EPPO Reporting Service (2007/070) : more details. Mainly along western coast of Honshu, but also southeast coast (Kii peninsula), and southern Kyushu.

According to Torii et al. (2011), mass mortality of Japanese oak trees became obvious in the 1980s (although it probably started in 1934 in the southern part of the Kyushu ilands) and it is now widespread in Japan.
