The relationship of a biotic factors indicate that wood decomposition activity of lessThan i greaterThan O.obesus O. feae and O. wallonensis Microtermes obesi, lessThan /i greaterThan and lessThan i greaterThan Coptotermes hemi lessThan /i greaterThan was significantly correlated with minimum temperature, relative humidity and rainfall NAGESWARA RAO.A AND CHINTA SAMMAIAH Bhadrachalam north forest, Odontotermes spp., wood degradation, vegetation, temperature 1075-1083
