This document discusses the up country live wood termite (Postelectrotermes militaris), a pest of tea plants in Sri Lanka. It describes the termite's life cycle of eggs, nymphs that develop into workers or supplementary reproductives, and winged adults. The termite colonies of 3000-5000 individuals reside in single tea bushes and damage plants by constructing galleries in the roots, collar, and branches, eventually causing wilting and breakage. Control involves removing and burning infested plants and roots.
