We found that decayed wood stakes with no sherpa jacket termite damage collected from a termite-infested field exhibited a deterrent effect against the termite Reticulitermes speratus, Kolbe, 1885.The effect was observed to be lost or reduced by drying.After identification, it was found that the decayed stakes were infected by brown rot fungus Fibroporia radiculosa (Peck) Parmasto, 1968.In a no-choice feeding test, wood blocks decayed by this fungus under laboratory condition Business Card Scanner deterred R.speratus feeding and n-hexane extract from the decayed stake and blocks induced termite mortality.

These data provided an insight into the interaction between wood-rot fungi and wood-feeding termites.
