Research Abstract

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.
