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.

从日本、台湾、泰国、越南和印度尼西亚采集了一种食心虫，即鸭嘴虫和一种日本栎枯萎病（JOW）的病原体--槲皮树（Raffaelea quercivora）。通过DNA分析确定了它们的同源性。病媒昆虫和病原体都存在于日本以外，但没有发生JOW。日本以外的Raffaelea quercivora分离株也对锯缘栎具有致病性。毒力不是由地区决定的。虽然国外鸭嘴兽的攻击性还需要进一步研究，但JOW仅在日本发生的原因可能与日本寄主植物的高敏感性有关。
