| Research Abstract |
An ambrosia beetle, Platypus quercivorus, and Raffaelea quercivora, a pathogen of the Japanese oak wilt(JOW) were collected from Japan, Taiwan, Thailand, Vietnam, and Indonesia. Their phylogeny was determined by DNA analysis. Both the vector insect and the pathogen existed outside Japan without the JOW incidence. Raffaelea quercivora isolates outside Japan were also pathogenic to Quercus serrata. The virulence was not determined by regions. The reason why the JOW occurs only in Japan may be related to high susceptibility of host plant species in Japan though more studies will be needed for aggressiveness of Platypus quercivorus overseas.
