| Outline of Final Research Achievements |
Fusarium solani species complex (FSSC) was dominantly detected from trunks of the declining coral tree, and the water conduction of the trunks was blocked in the area of fungal distribution. The pathogenicity of two dominant strains was confirmed by the artificial inoculation of healthy seedlings with candidate fungal strains. The present investigations revealed the decline and mortality of coral trees are caused by a fungus that belongs to FSSC, and Quadrastichus erythrinae is not the cause of the decline. The pathogenic fungus is included in the ambrosia Fusarium clade of FSSC and symbiotic relationship of the pathogenic fungus with ambrosia beetles was suggested.
