| Descripción: | The antitermitic activity of different extracts obtained from Tectona grandis L.f was investigated against Coptotermes curvignathus (Holmgren). The main objective of this work was to determine the mortality rate of termites by the teak wood extracts. Different extracts exhibited different degree of antitermitic activity. A teak wood with age of 39-59 years and 59-79 years were selected from Purwakata and Cepu regions of Indonesia, respectively. As per earlier reports, quinones are considered as toxic to termites, and these quinones are found in abundance in teak wood. Among the extracts of petroleum ether, acetone/water (9:1), and ethanol/water (8:2), the acetone/water (9:1) extracts exhibited strong activity. The surface morphology of extracted wood samples was observed by scanning electron microscopy in order to reveal evidence of change. |
