The susceptibility of oriented structural straw board (OSSB) to damage by subterranean wood-destroying and grass-feeding termites in Australia
2014 - IRG/WP 14-40683
The field performance of untreated oriented structural straw board (OSSB) made from wheat straw was evaluated against two economically important Australian species of wood destroying subterranean termite, Coptotermes acinaciformis and Mastotermes darwiniensis, and two Australian species of grass-feeding subterranean termite, Amitermes meridionalis and Nasutitermes triodiae. Oriented strand board (...

Shells of Coconut and their Durability against Termite Attack
2015 - IRG 15-10853
All tropical and subtropical areas of the Earth are inhabited by termites. In climates with moderate temperatures, they occur less frequently. Especially wood and non-wood materials that grows in tropical areas and used there in timber constructions and woodworking, wood durability and protection against termites should be researched. This paper reports findings from an experimental “AW011” la...

Termite Management and the U.S. Experience: A Case for Wood Treatment & Integrated Control
2015 - IRG/WP 15-30678
A brief overview of termite control is given using specific experiences from the U.S.A. Five major types of termite treatment now prevail: soil applied chemical barriers, in-structure chemical barriers (in-situ applied wood and foundation treatments), physical barriers, treated wood and termite baits. In general, ‘stand-alone’ pretreatments or ‘primary’ treatments are often discussed and ...

Evaluating the Effects of Post Dip-Treatment Laser Marking on Resistance to Feeding by Subterranean Termites
2016 - IRG/WP 16-10854
Dip-treatment of wood packing materials is often used instead of pressure treatment mainly because of issues relating to simplicity and cost. Packaging boxes fabricated for the United States Army are required to be dip-treated for at least one minute in an approved preservative solution prior to use. These boxes are expected to have a service life of up to 20 years in a wide variety of environment...

New approach to improve the estimation of colony population in subterranean termites (Blattodea: Rhinotermitidae)
2016 - IRG/WP 16-10866
The aim of this study was to estimate the mortality and fading effects of dye markers Neutral red and Nile blue commonly used in the estimation of termite colony population, in order to determine the decrease rate from the initial number of marked and released termites. This rate can be considered in the application of the different indexes used to calculate the number of termites of the colony. I...

Assessment of the biological durability of wood treated with organosilicon compounds
2016 - IRG/WP 16-30685
The European wood construction market is in need of environmentally friendly wood-based products whose service life meets the expectations of end users. Non-biocidal silicon-based water repellents, which can be applied to different materials, help minimize their vulnerability/susceptibility to liquid water. Consequently, they have the potential of increasing wood’s resistance against decay fungi...

UV-curable coatings developed for aesthetic and biological protection of wood outdoors
2017 - IRG/WP 17-40821
To avoid wood greying, dimensional variations, and degradation by biological agents wood is protected with preservation products and coatings when used outdoors. For some wood species used for cladding, a treatment with a preservation product is required, and is frequently additionally protected with a coating. In this study, Mäder Group developed a new UV-curable coating for outdoors application...

Evaluation of the Virulence of the Termite Species Occurring in the French Tropical Overseas Territories
2018 - IRG/WP 18-10913
The French tropical overseas territories are strongly affected by termites’ activity, which is especially devastating because the species encountered there are among the most virulent in the world. That is why in these regions it is particularly important that producers and users of wood-based products are provided with materials and preservative products whose durability and efficacy has been t...

Evaluation of the effect of zwitterionic buffers on termite gut protists
2018 - IRG/WP 18-10933
The thermal modification of wood is recognized as the most commercialized wood modification process. The treatment of wood at temperatures usually greater than 180 ºC results in a product with some properties enhanced (dimensional stability, durability, aesthetical colour) and some diminished (mechanical properties). The loss of mechanical strength is recognized as a limitation to the use of ther...

Long-time efficacy of some soil termiticides tested according to “Modified Ground Board Test”
2018 - IRG/WP 18-10935
Field trials of efficacy of soil termiticides available in Thailand were started back in the 1980s at four different locations representing different unique weather types of the country. The method used in the trials (Modified Ground Board Test) is the compulsory test for every soil termiticides aiming to be registered for termite control in Thailand. The ongoing record reveals that some particula...

Protocol of intervention against subterrranean termites in urban areas
2018 - RG/WP 18-20640
Subterranean termites are a problem of Mediterranean countries since their climatology favours their development. In Spain, termite attack is very important in cultural heritage and even in new construction, as they can cause serious damage to structural elements (pillars, beams, decks, etc.), carpentry (doors, windows, etc.) and wooden goods (furniture, paintings, libraries, etc.), causing not on...

Degradation of Eucalyptus transmission poles varies across regions in Zambia
2018 - IRG/WP 18-30727
Evidence from literature shows that Eucalyptus poles treated with creosote last over 30 years before replacement. However, in Zambia, the life span of such poles has reduced to 5-10 years. The aim of this study was to investigate factors associated with degradation of treated Eucalyptus poles and how these varied across regions in the country. A total of 1200 poles were assessed in three differen...

Preserved Wood in the Story of Sustainable Forestry
2018 - IRG/WP 18-50344
Sustainable forestry, at its simplest, is about growing trees. The full story, though, is much more complex. An important chapter of that story is the role that preserved wood plays in ensuring sustainability. Too often, this part of the sustainability story is rarely mentioned.
It is time for the preserved wood industry to deliver a unified message of our critical role in sustainability. By res...

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...

Use of resin obtained from Italian guayule crops for wood preservation purposes: some preliminary results
2019 - IRG/WP 19-30736
The potential of guayule (Partenium argentatum Gray) as a source of anti-termite, anti-fungal and insect repellent products to be used in wood preservation, has been largely explored in the past.
The fact that such products are obtained as byproducts in the process of natural rubber extraction from this plant, thus increasing the profit of the process, together with the ability of this crop to gr...
