| Research Abstract |
Wet and dried samples prepared from stakes decayed in the field were subjected to the termite feeding bioassay using Reticulitermes speratus. Termite-feeding deterrence was clearly observed on the wet sample but not on the dried sample. The fungus isolated from the stake was identified as Fibroporia radiculosa. The phenomenon mentioned above was also observed on Japanese red pine wood samples decayed by the fungus in a laboratory scale test. The active substances causing termite-feeding deterrence were contained in n-hexane fraction and possibly volatiles. In future, the extended fractionation will be conducted to clarify chemical structures of the feeding deterrents.
