Depth of foraging of subterranean termites in tropical Australia
1996 - IRG/WP 96-10141
Stakes of radiata pine (Pinus radiata D.Don) of varying lengths to 800 mm were inserted vertically in the soil with all but their lower 100 mm sheathed in a capped UPVC tube representing a physical barrier to termites. In one series of trials, termites were encouraged to aggregate at the upper ends of the tubes, in order to determine whether they would descend to the lower end of the barrier. In a...

Envelope treatment to protect softwood timbers from damage by subterranean termites
2003 - IRG/WP 03-30313
Two aboveground field trials were conducted in Australia to determine the effectiveness of envelope treatments of deltamethrin and permethrin for the protection of softwood framing timbers against termite damage. Radiata pine Pinus radiata D.Don and slash pine Pinus elliottii Englem., were treated with Tanalithä T (a novel solvent) to achieve 5-mm-depth envelopes. Details of a field trial against...

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...

Protection for whole-of-house timbers from subterranean termites in Australia
2005 - IRG/WP 05-20315
A field study was designed to increase maximum protection of whole-of-house timbers against subterranean termites. Concrete slab and suspended floor simulated houses were constructed using untreated and treated (slow acting toxicants) timber frames. The treated and untreated timber structures within the simulated houses were exposed with or without soil chemical and/or physical barriers in the fie...

Efficacy of triflumuron dust against Schedorhinotermes intermedius (Isoptera: Rhinotermitidae)
2000 - IRG/WP 00-30226
Insecticidal dusts have been used against termites for decades, with arsenic dust being the standard in Australia. While fair success over the years has been achieved against genera such as Coptotermes and Nasutitermes, Schedorhinotermes has been much more difficult to control. This genus has nests which are very difficult to locate and thus it is problematic to determine whether a treatment has b...

Whole-of-house protection from subterranean termite attack and damage after four years of field exposure
2008 - IRG/WP 08-10665
This study reports the condition of the whole-of-house termite protection test in tropical Australia after four years. The study was designed to provide maximum protection to whole-of-house timbers in a natural situation posing the highest hazard from subterranean termite populations. The houses were constructed either on concrete slabs or suspended floors using untreated and treated timber fram...

The case for using borates in termite control in tropical Australia
2011 - IRG/WP 11-30573
A brief historical overview of boron based wood preservatives efficacy against subterranean termite management worldwide, and in Australia, is presented. The boron based compounds to be used in H2 hazard conditions, may be applied as a surface treatment by dip, flood coat or spray, and rapidly penetrates to the centre of timber substrates, whether containing sapwood or heartwood. However, section ...
