Susceptibility of softwood bait stakes to attack by subterranean termites (Isoptera: Rhinotermitidae)
1994 - IRG/WP 94-20037
Sapwood stakes of Australian-grown Araucaria cunninghamii (hoop pine), Pinus elliotii (slash pine), Pinus radiata (radiata pine) and North American-grown Pinus sp. (southern yellow pine) were exposed to subterranean termite attack in an in-ground bioassay. Stakes in bait containers and bare stakes were attacked by Coptotermes acinaciformis and Schedorhinotermes intermedius. Basic susceptibility of...

Borate Protection and Termites: Variation in Protection Thresholds Explained
2006 - IRG/WP 06-20324
Laboratory and field data reported in the literature are confusing with regard to ‘adequate’ protection thresholds for borate timber preservatives against subterranean termites. The confusion is compounded by differences in termite species, timber species and test methodology. Laboratory data indicate a borate retention of 0.5% mass/mass (m/m) boric acid equivalent (BAE) would cause > 90% t...

Termite resistance of DMDHEU-treated wood
2008 - IRG/WP 08-40401
Chemical wood modification with dimethyloldihydroxy-ethyleneurea (DMDHEU) or its derivatives are applicable to both solid lumber and wood-based composites. Advantages of DMDHEU-based modification are an increase of dimensional stability and high durability against white, brown and soft rot fungi. At higher chemical loadings, the hardness of the wood is considerably increased. Due to the durabil...

Termite resistance of some modified wood species
2009 - IRG/WP 09-40449
During the last few decades, researchers worldwide have investigated and developed new treatment techniques to improve intrinsic wood properties. Some of these techniques were introduced to the market recently and are gaining in importance.. Various wood properties of these new materials have been studied intensively. These include physical-mechanical properties (dimensional stability, moisture ...

Management of invasive West Indian drywood termite in Queensland: Transition from mandatory to voluntary treatment
2023 - IRG/WP 23-11002
Cryptotermes brevis, the West Indian drywood termite (WIDT) is the most destructive drywood termite globally. It is capable of infesting both softwoods and hardwoods in timber structures. In Australia C. brevis was first discovered in 1940s and later an established infestation was discovered in Maryborough, Queensland in 1966 and then in Brisbane and Bundaberg in 1975. In 1977 the Queensland Gover...

Synergized pyrethrins insecticide as a spot treatment option for West Indian drywood termites
2023 - IRG/WP 23-11004
Pyrethrin is a natural biopesticide with relatively low mammalian toxicity. Two identical products in Australia contain pyrethrin in liquid CO2-propelled aerosol, Pestigas from BOC international and SupaPy Supagas. In the current study, the toxicity of SupaPy was tested against West Indian drywood termite Cryptotermes brevis as an option for spot treatment of this pest. Termites were exposed to wo...
