Scolicosporium sp., the causal fungus of Japanese cedar sclerotial dieback of Cryptomeria japonica, is frequently isolated from the insect galls of Contarinia inouyei Mani. formed on the needles. It was made clear that the pathogen took root in the needle tissue by taking advantage of the insect galls. To success the infection from the galls, the pathogen must overcome the inhabiting fungi in the galls. The results of studies were showed that no antagonistic fungi against the pathogen existed in the gall, and also epidermal cells were lacking in the inner walls of the gall. Therefore, the above facts enabled to success the infection from the galls of the pathogen. Secondary metabolite, chlorogenic acid and amino acid, existed in the gall in plenty, in comparison with the normal tissue. However, the evidence whether chlorogenic acid and amino acid will support the infection of the pathogen was not able to obtain in this study.

Scolicosporium sp.，日本柳杉（Cryptomeriajaponica）的日本雪松菌核枯梢病的致病真菌，经常从Contariniinouyei Mani的虫瘿中分离。形成在针上。明确了病原菌是利用虫瘿在针叶组织中生根的。病原菌要从虫瘿中侵染成功，必须克服虫瘿中的真菌。研究结果表明，在虫瘿中不存在对病原菌有拮抗作用的真菌，虫瘿内壁也缺乏表皮细胞。因此，上述事实使病原菌的虫瘿感染成功。次生代谢产物绿原酸和氨基酸在虫瘿中的含量较正常组织丰富。但是，本研究未能获得绿原酸和氨基酸是否支持病原菌感染的证据。
