Review of candidate graded particle barrier testing methods in Australian Standard (AS 3660.3 – 2000): Assessment criteria for termite management systems
2009 - IRG/WP 09-20417
The Australian Standard (AS. 3660.3 – 2000) for assessment of candidate graded particle termite barriers is reviewed and suggestions for amendments are made. Areas requiring amending in light of current biological knowledge involve the inclusion of proprietary or patented systems rather than generic types; selection of test termites in the genus Coptotermes; duration of test periods; and inadequ...

Laboratory study on the termiticidal efficacy of Eremophilone oil
2009 - IRG/WP 09-30497
A novel timber preservative formulation, Termilone® TT, is being developed by BioProspect Limited. This environmentally friendly preservative formulation incorporates Eremophilone oil, extracted from Eremophila mitchellii, as the active ingredient. Chemical analysis performed on Pinus radiata sapwood specimens treated with the Termilone® TT formulation revealed that the Eremophilone oil is relat...

Evaluation of formulation type on the efficacy of bifenthrin as a glueline termiticide for veneer based wood products
2010 - IRG/WP 10-40486
Field trials were carried out in Australia on Coptotermes acinaciformis to evaluate the efficacy of various bifenthrin formulations. One trial tested plywood made by Zelam at their research facility in New Zealand and compared three emulsifiable concentrate formulations (EC), a suspension concentrate (SC) and an encapsulated formulation (CS). A second trial compared laminated veneer lumber (LVL)...

Towards designing eco-friendly buildings with in-built termite protection
2010 - IRG/WP 10-50273
The increase in greenhouse gases, leading to global warming, is considered by a consistent scientific worldview not due to natural variation, but due to the growing concentration of carbon dioxide (CO2), methane (CH4) and other atmospheric pollutants. Global emissions of carbon dioxide from fossil fuel combustion and cement production rose from 22.6 billion tons in 1990 to an estimated 31.2 billio...

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 ...

Preliminary laboratory bioassay to evaluate engineered Fibre-boards against subterranean termites C. acinaciformis (Isoptera: Rhinotermitidae)
2012 - IRG/WP 12-10768
In Australia, laboratory bioassays with subterranean termites typically contain groups of workers and soldiers in a substrate of moist mound material. This termite substrate may affect termite consumption, and the test materials create a favorable termite condition for the test. The main purpose of this test is to examine the effect of a melamine formaldehyde treatment of wood panels to evaluate t...

Thiacloprid as a glueline termiticide for veneer based wood products
2012 - IRG/WP 12-30592
Thiacloprid is an insecticide commonly used in the agricultural industry. No evidence of its commercial use in wood has been discovered by the authors. Results are reported for veneer based wood products treated with thiacloprid via the glueline. Thiacloprid was tested against Coptotermes acinaciformis following the brick assembly technique as described in the Australasian Wood Preservation Com...

Biological performance of wood- and bamboo-polypropylene composites: Effects of particle content, particle size and Zn borate
2012 - IRG/WP 12-40577
Particle content and size of wood material in wood plastic composites (WPCs) can affect efficacy of WPCs against fungi and termites. This study evaluated fungal and termite resistance of WPCs manufactured by using two different levels of particle content (50 and 70%) and three different particle sizes (30, 60, and 100 mesh). In fungal resistance tests, Tyromyces palustris, a standardized test fung...

A comparison of the resistance of pyrethroid-treated wood to damage by Coptotermes acinaciformis in Australia and C. formosanus in China and the USA
2014 - IRG/WP 14-10830
Field trials, using a single aboveground method of exposure, were used to assess a range of retentions of two pyrethroids (bifenthrin and permethrin) in Pinus radiata D. Don sapwood against two species of Coptotermes in three countries to provide directly comparable results. Coptotermes acinaciformis (Froggatt) in Australia, C. formosanus Shiraki in China and C. formosanus in the USA consumed simi...

Comparison of untreated plywood and untreated LVL in a field trial against Coptotermes acinaciformis and in laboratory trials against Tyromyces palustris and Coniophora puteana
2014 - IRG/WP 14-40671
In Australasia, efficacy data obtained on plywood is generally acceptable for laminated veneer lumber (LVL) and vice versa. This is particularly the case with glueline treatment approvals. The rationale is that the two wood products have predominately the same basic structure with the key difference being orientation of the veneer. LVL typically has all veneers in parallel while plywood typical...

Application of nano metal fluorides against termites
2019 - IRG/WP 19-30733
Recent research has shown that fluorides such as NaF have potential as a wood preservative against termite attack (Pan and Wang, 2015). However, NaF has high leaching susceptibility because of its solubility (40 g/l ) which can reduce its efficacy over long term. Metal fluoride nanoparticles such as MgF2 and CaF2 present a viable alternative to water soluble fluoride-based wood preservatives as th...

Occurrence of synanthropic beetles (Coleoptera Ptinidae) and checkered beetles (Coleoptera Cleridae) in relation to climatic factors in historical buildings from North-Eastern Germany
2021 - IRG/WP 21-10980
Predatory checkered beetles occur in many historical buildings. Thus, it is essential to learn more about the ecology of these beetles, specifically for their further use as suitable beneficial organisms in biological control of wood-destroying insects. In this study, indoor climatic conditions were examined as a major factor influencing their occurrence and that of their prey Anobium punctatum an...

A novel method for assessing radial variation in termite resistance of timber
2023 - IRG/WP 23-11005
Australia has many timbers whose heartwood is highly resistant to fungal and termite attack; however, changing public policies have resulted in restricted access to many native forests where these species are found. Plantations of these same species are expected to replace these resources, but there are questions concerning whether timber from these trees will have the same resistance as the nati...

Efficacy of a wide-spectrum plant bio-based anti-termite product - Laboratory trials
2023 - IRG/WP 23-11024
Compared to the number of timbers available, the list of wood species resistant to termites is rather limited and largely composed of tropical timbers. In addition, due to climate change and environmental degradation, together with global trade, a significant global expansion of termites is predicted along with the economic losses due to their activities. Therefore, there is a demand to find produ...

Laboratory evaluation of PA1b, an insecticidal protein extracted from pea seeds (Pisum sativum), as bait active ingredient against the subterranean termite Coptotermes gestroi (Blattodea: Rhinotermitidae) in tropical zones
2024 - IRG/WP 24-11038
Coptotermes gestroi (Wassman 1896) is one of the worst pests in tropic areas, economically. Two types of curative methods are used since decades to eliminate colonies that attack constructions: injection of biocidal treatment solutions on wood, walls and soil, and population control using baits. In application of the current regulations, the first technique can no longer be used in Europe, to lim...
