Various experimental testing procedures were undertaken in Indonesia to determine the effectiveness of a patented superficial (envelope) treatment using bifenthrin to protect radiata pine framing material from damage by two species of subterranean termites (Macrotermes gilvus and Coptotermes curvignathus) and one species of drywood termite (Cryptotermes cynocephalus). Lengths of framing material (Pinus radiata sapwood) were commercially treated to the targeted retention of 0.02% m/m of bifenthrin in the outer 2 mm depth penetration zone of the material. The treated and untreated materials were subsequently cut into test specimens and exposed to M. gilvus in the field and a semi-laboratory trial, to C. curvignathus in the laboratory and a semi-laboratory trial and to C. cynocephalus in a laboratory trial. No supplementary treatment was performed on the exposed cut ends of the treated test specimens. The results from the trials clearly demonstrated that the superficial treatment of bifenthrin seemed effective in protecting test specimens of radiata pine framing material from significant damage by Indonesiaâs most notorious termite species that often causes serious economic loss to the timbers. Termites were unable to damage any of the bifenthrin-treated surfaces of test specimens. Any obser ved damage by termites, albeit minor, was in all cases confined to the exposed cut ends of test specimens. In contrast, attack by termites on the untreated control test specimens caused damage of the samples ranging from light to heavy.

Pathogenicity of two species of entomopathogenic agents to subterranean termite Coptotermes gestroi Wasmann (Isoptera: Rhinotermitidae) in laboratory. Pathogenic effcts of two species of entomopathogenic agents, Metarhizium anisopliae and Bacillus thuringiensis A ard B, were trested to subterranean termite Coptotermes gestroi Wasmann in laboratory. Three groups of rhc tcrti~ite tclor.ker:s were each e.xposed to a treated filter paper with one of the entomopathogenic agents for one minute. Twenty-five termite workers and three soldiers were then transferred to a wetfilter paper disk that had been installed in a plastic vial. The test materials were stored in a dark and humid at room temperature for 14 dc~j'.s. Five replicates were provided. Observations were conducted daily to determine termite nlortality urld take out dead termites. Reszllts showed that the fungus M. anisopliae was more pathogenic than Bt. A and B. After being exposed to treated paper with the fungus, all test termites died within 8-10 days. Treatments with B. thuringierisis A and B did not produce high mortality, and seemed to be not different from the control, only causing less than 3% termite mortality until the end of the tests.

Most of Indonesian wood species are classified as less durable, so preservation is needed. Wood preservation inIndonesiamainly depends on imported preservatives. The preservatives are not only toxic to wood destroying organism but also to humans and the environments. Therefore alternative to treat wood should be sought and developed in term of the preservatives used as well as the methods. One that can be proposed is treating wood at high temperature combine with environmentally friendly preservatives, as tried in this experiment.The wood species used in this experiment were rubber wood (Hevea brasilliensis) and pine (Pinus merkusii). Both woods were treated with borax at two concentrations (3% and 5%) by cold-soaking method for 24 hours. The treated woods were subsequently air dried. Then those woods were treated at three levels of high temperature (180ºC, 200ºC, and 220ºC) in an oven for one hour. Finally, the treated wood samples were laboratory-tested by assessing their resistance to dry wood termites (Cryptotermes synocephalus Light.) and powder-post beetles (Heterobostrychus aequalis Wat).The results revealed that increases of heating temperature and concentration of preservatives resulted in more durable woods. In this regard their resistance to dry wood termite and powder-post beetles was increased as shown by smaller weight loss. Treating wood at temperature of 180ºC combined with borax at concentration of 3% resulted in 100% termite mortality on rubber wood and pine.
