A comparative study of termite resistance of 28 Indonesian wood species has been conducted using small samples measuring 5 x 10 x 20 mm³. The drywood termite Cryptotermes cynocephallus (Kalotermitidae) and the subterranean termite Coptotermes curvignathus (Rhinotermitidae) were used in the study. A resistance classification was derived on the basis of cluster analysis. The result reveals that Albizia procera, Dalbergia latifolia, Eusideroxylon zwageri, Tectona grandis and Intsia bijuga are completely resistant to both species of termite. Albizia chinensis and Artocarpus integer are resistant only to Cryptotermes cynocephallus, but vary between resistant and moderately resistant to Coptotermes curvignathus. Other wood species are classified as moderately resistant, susceptible or very susceptible.
