Two regrowth wood species, i.e. tusam (Pinus merkusii Jungh. et de Vr.) and mangium (Acacia mangium Wild.) were used in this study. Specimens measuring 25 mm x 25 mm x 50 mm and 5 mm x 25 mm x 25 mm were prepared for testing against dry-wood termite (Cryptotermes) and subteranean termite (Coptotermes) respectively. All specimens were air-driedÂ to approxi mately 16-18%Â moisture content. One group of the specimens was furtherÂ oven - dried to reach moistureÂ content ofÂ 6-8%.Â FurfurylationÂ was carried out by soakingÂ wood specimens for 24 hoursÂ in a 98% fuifurylÂ alcoholÂ solutionÂ containingÂ 0.35%Â (v/v) ofÂ ZnCl2Â as catalyst. Furfurylated specimens were then cured atÂ l000CÂ for 48 hours.Â Control and treated specimens were exposed to dry-wood and subteranean termites for 12 and 4 weeks respectively.Treated specimens revealed a weight gains ofÂ 10 to 40 % depending on size of specimens andÂ wood species. Speciesmens usd for testing drywood termites gained less weight than those ofÂ subteranean termites. TusamÂ specimensÂ markedlyÂ showedÂ aÂ higherÂ weightÂ gainÂ than mangium.Â Furfurylation using method 1 resulted in comparable weight gain to that of method 2. Control specimens of tusam an mangium are both encountered susceptible to dry-wood and subteraneanÂ termiteÂ attacts.Â TusamÂ hadÂ less initial durabilityÂ againstÂ CoptotermesÂ than mangium, but the wood species had a similar durability against Cryptotermess.Â The modified wood with furfuryl alcohol abviously possessed an improved durabilityÂ upon the two termites. Tusam specimens gained more durability improvement than mangium.
