The abundance and biomass of termites in dead wood were estimated in a dry evergreen forest in Thailand. Litter and dead wood were collected within ten 2 x 2 m quadrats on a 100 m transect, and then all termites in the litter and dead wood (= termites in dead wood) were dislodged. The biomass of litter and dead wood was 2.50 kg (dry weight) m2, of which 76% was represented by dead wood with a diameter of 2 1 cm. A total of 239 pieces of dead wood (diameter >= 1 cm) were collected, and 38 of them contained termites, The frequency of termites in dead wood was significantly different between pieces with a diameter of 1-5 cm and pieces with a diameter of 25 cm. The abundance and biomass of termites in dead wood were 1269 termites m2 and 3.53 g m, respectively. A total of 11 species. comprising Kalotermitidae. Rhinotermitidae and Termitidae, were collected: all of them belonged to the wood/litter-feeding group. Using our previous estimation for ter- mites in the soil and data from other studies, the abundance and biomass of termites in the dry evergreen forest were estimated to be 7794 termites m2 and 16.7 g m2, of which 16 and 21%, respectively.
