A method and apparatus for rapid assessment of termite barriers.
2007 - IRG/WP 07-20366
This paper describes an apparatus for rapid assessment of barriers to subterranean termite foraging. The method and apparatus arose from the development of a novel physical termite barrier. The barrier had to be flexible, resilient, able to be applied as a liquid and be neither toxic nor repellent. This posed a special problem as existing laboratory assessment techniques did not offer a sufficient...

2007 - IRG/WP 07-10616
This document is a combination of two articles previously submitted to the journal, Sociobiology.
Lethal dose of fipronil was determined in two experiments: topical application and contact with treated sandy loam. In the topical application the toxicity of fipronil was evaluated against workers of a laboratory colony of Coptotermes formosanus Shiraki. Fipronil was applied by the microsyringe to t...

Tunneling patterns of the subterranean termite species Reticulitermes grassei (Isoptera: Rhinotermitidae)
2007 - IRG/WP 07-10619
The cryptic habits of subterranean termites restricts detailed analysis of their foraging patterns in situ, but the process is evidently dominated by tunnel constructions connecting the nest with woody resources discovered within the territory of each colony. In this study, tunnel formation and orientation were studied experimentally in the termite Reticulitermes grassei (Clément), using 2D labor...

Evaluatiang the potency of cinnamaldehyde as a natural wood preservatives
2007 - IRG/WP 07-30444
Since cinnamaldehyde, the major constituent of leaf essential oil from Cinnamomum osmophloeum, has significant antifungal and antitermitic activities, it is worthy of understanding whether cinnamaldehyde has potential to be used as a natural preservative for improving the durability of wood. In this study, the fungi and termite resistance of cinnamaldehyde-treated wood (CTW) were evaluated accordi...

Developments in Borate Treatment of Canadian Species for Decay and Termite Resistance
2007 - IRG/WP 07-30443
The increased interest in boron treatment of wood over the past 20 years is mainly due to its environmental acceptability, potentially deep penetration in wood, and its efficacy against decay and termites. Based on Forintek’s research in the past two decades, the boron penetration and retention requirements for decay and termite protection in various national and international standards for Cana...

Development of boron/linseed oil combined treatment as a low-toxic wood protection. Evaluation of boron fixation and resistance to termites according to Japanese and European standards
2007 - IRG/WP 07-30448
Combinations of boric acid as a first step of treatment and linseed oil as a second step have been performed in order to enhance boron retention to leaching and wood resistance to termites. Classic leaching and termites resistance standards are inappropriate to evaluate this combination which can be considered as both a wood core preservation treatment and a coating.
Japanese Industrial Standard...

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...

Needs for wood durability research on planted tree species in the tropics
2008 - IRG/WP 08-10651
The area of forest plantation has been expanding especially in tropical Asia since 1990’s. Most of them are developed for pulp and paper industries and planted with fast growing trees. It is expected that wood from those fast growing trees are also used for value added products such as sawn timber. In order to promote the utilization of fast wood as the resource of value added products, natural...

Preliminary investigation of biological resistance, water absorption and swelling of thermally compressed pine wood panels
2008 - IRG/WP 08-40396
Wood can be modified by compressive, thermal and chemical treatments. Compression of wood under thermal conditions is resulted in densification of wood. This study evaluated decay and termite resistance of thermally compressed pine wood panels at either 5 or 7 MPa and at either 120 or 150?C for one hour. The process caused increases in density and decreases in thickness of the panels; however, lab...

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...

Wood Decay Research Using Molecular Procedures, What Can It Tell Us?
2008 - IRG/WP 08-10678
There are many unanswered questions in wood decay and protection research, and no single research technique will ever answer all of these questions. The process of wood decay is a very complex series of biochemical and chemical reactions that are heavily influenced by the hundreds of bacterial and fungal species found on environmental samples of wood. There are a variety of molecular techniques b...

Performance of dip and pressure treated wood in termite ground proximity exposures in Hilo, HI, and Colombia
2008 - IRG/WP 08-30491
A number of preservative systems were evaluated for their ability to control termite attack when applied as both dip and pressure treatments. With dip treatments, better performance was observed with southern pine than spruce-pine-fir using the same solution strength treatment, probably as a result of the about 50% greater uptake with southern pine and associated deeper preservative penetration. B...

What Can Fecal Pellets Tell Us About Cryptic Drywood Termites (Isoptera: Kalotermitidae)?
2009 - IRG/WP 09-20407
Drywood termites (Isoptera: Kalotermitidae) are serious economic pests of both plants and seasoned wood (furniture, wood frame structures). Currently, five species of kalotermitids are known to occur in the Hawaiian Islands: Neotermes connexus, Incisitermes immigrans, Incisitermes minor, Cryptotermes brevis, and Cryptotermes cynocephalis. These termites are difficult to detect and observe due to ...
