Feeding preference behaviour of Crytopermes cynocephalus Light and Coptotermes curvignathus Holmgren on twenty-eight tropical timbers

IRG/WP 1251

Nana Supriana

A study on the feeding preference behaviour of a dry-wood termite Cryptotermes cynocephalus Light and a subterranean termite Coptotermes curvignathus Holmgren on 28 species of tropical timbers has been conducted. The weight-loss of individual timber and the mortality of termite was·recorded after 5, 10, 15, 20 and 25 days of exposure. The results reveal that there are only five species among 28 species of wood which are completely repellent to both the dry-wood termite Cryptotermes cynocephalus and the subterranean termite Coptotermes curvignathus. These five wood species are Dalbergia latifolia, Eusideroxylon zwageri, Intsia bijuga, Lagerstromia speciosa and Tectona grandis. There are eight wood species which are repellent to Cryptotermes cynocephalus and seven wood species which are repellent to Coptotermes curvignathus. There are also only seven wood species which are completely arrestant or highly arrestant to both species of termite. Agathis alba and Mangifera indica are classified as highly arrestant to both the dry-wood and the subterranean termites. Other species are classified between moderately repellent to highly arrestant.
