| Outline of Final Research Achievements |
Filamentous fungi were isolated from fungal gardens of the non-social lizard beetle Doubledaya bucculenta (Coleoptera: Erotylidae: Languriinae), which cultivates the yeast in the internodes of recently dead bamboo culms. These secondary fungi acted as weeds in the fungal gardens of D. bucculenta, inhibiting both growth of the beetle larvae and proliferation of the beneficial yeast. However, growths of the fungi were suppressed in the presence of both yeast and D. bucculenta larvae. The beneficial yeast was exclusively detected from mycangium of female adults of D. bucculenta. I found a related species of D. bucculenta associating with yeast in Vietnam.
