Laboratory Evaluation of Termite Resistance of Five Lesser-known Malaysian Hardwoods Used for Roof and Ceiling Construction
The general laboratory procedure of AWPA E1-97 was used to evaluate the termite resistance of 5 lesser-known species (LKT) of Malaysian hardwoods: Kekatong (Cynometra sp.), Kelat (Eugenia spp.), Mempening (Lithocarpus spp.), Perah (Elateriospermum tapas) and Pauh Kijang (lrvingia malayana) agains...

| Summary: | The general laboratory procedure of AWPA E1-97 was used to evaluate the termite
resistance of 5 lesser-known species (LKT) of Malaysian hardwoods: Kekatong
(Cynometra sp.), Kelat (Eugenia spp.), Mempening (Lithocarpus spp.), Perah
(Elateriospermum tapas) and Pauh Kijang (lrvingia malayana) against the subterranean
termite Coptotermes curvignathus over 28 days. Kempas (Koompassia malaccensis) and
Rubberwood (Hevea brasiliensis) were included for comparison with these LKT.
Employing the A WP A five-point visual rating scale of termite resistance of wood
material, Rubberwood and to an extent Mempening, were the least resistant (rating 4-7),
Kekatong was virtually immune (rating 9) to the Coptotermes species, while Kempas,
Kelat, Pauh Kijang and Perah sustained between light-to-moderate attack (rating 7-9).
There was a tendency for higher final wood moisture content, higher mass loss or
reduced termite mortality to correspond with the lower visual ratings (low termite
resistance) generally. In-ground natural durability test results did not correlate with mass
loss or visual rating data from the laboratory test. |
