Techniques for field assessment of particulate termite barriers
2000 - IRG/WP 00-10376
Field testing of particulate termite barriers poses problems different from those encountered when testing preservatives or soil termiticides. To ensure an adequate level of challenge, and minimise the risk of a Type II error, the experimental design must promote termite activity and provide a significant, readily detectable, food source which can only be reached by penetrating the test barrier. I...

Experimental real building evaluation of termite attack - Effect of the space between the mat foundation and the thermal insulation
2000 - IRG/WP 00-10374
For evaluating the termite resistance of the real house foundation, specially in the case of thermal insulation systems for foundation walls, thermal insulation which can be attacked by termite, must be evaluate. Because of the difficulty of the water penetration of thermal insulation, the water barrier systems can be protected against termite attacks, in our opinions. The observation on the proce...

Termite barriers for new construction
2000 - IRG/WP 00-10341
Subterranean termite protection in Australia has traditionally relied upon the creation of a zone of poisoned soil under and around the structure to prevent termite attack from the ground. The transition away from persistent soil poisons which began with the withdrawal of cyclodienes in 1995 provided market opportunities for innovative barrier systems. The new barrier systems currently being used ...

A hypothesis on a second non-biocidal property of wood extractives, in addition to toxicity, that affects termite behavior and mortality
2008 - IRG/WP 08-10638
While it is has long been recognized that heartwood extractives affect termite behavior, the exact cause and relationship between total extractives, extractive types, and termite resistance remains unclear. Generally, researchers have proposed that the extractives are toxic and/or repel termites. We propose, based on the well known fact that many extractives have excellent antioxidant properties...
