The aim of this study was to clarify occurrence mechanisms of Japanese oak wilt disease exploring both factors affecting the pathogenicity of a pathogen, Raffaelea quercivora and the origin of the pathogen. Since the disease can be outbreak in abroad, we inventoried members of the genus Raffaelea in Asian countries. As the results, following issues were found ; 1. Enzymatic activity of the pathogen was associated with pathogenicity, 2. Complex defense mechanisms of host trees species via both static and dynamic responses might be affecting differences of susceptibility among the fagaceae species, 3. Some foreign fagaceae species might be higher in their susceptibility against this disease, and 4. Members of Raffaelea species, Platypus quercivorous, and Platypodidae insects were distributed in Asian countries.

本研究的目的是阐明日本橡树枯萎病的发生机制，探讨影响病原体 Raffaelea quercivora 致病性的因素和病原体的起源。由于该病可能在国外爆发，我们对亚洲国家的拉斐尔属成员进行了清查。结果发现以下问题； 1. 病原体的酶活性与致病性相关，2. 寄主树种通过静态和动态反应的复杂防御机制可能影响壳斗科物种之间易感性的差异，3. 一些外来壳斗科物种对该病害的易感性可能更高，4. 拉斐尔物种、鸭嘴兽和鸭嘴兽科昆虫的成员分布在亚洲国家。
