Worker aggregation and baiting for management of subterranean termites
1994 - IRG/WP 94-10052
Environmental concern in the current use of cyclodiene and other chemicals for subterranean termite control had led to search of alternative environmental friendly management strategies. Worker aggregation and baiting are promising strategies. Aggregation is mediated through food recognition, attraction to some synthetic chemicals such as d-camphor, cinnamyl alcohol and sereral styryl compounds, s...

Persistance of active ingredients in treated wood
1993 - IRG/WP 93-50001-20
Disposing of chemically protected waste wood implies the distinction between surface and pressure treatment. Considering that barked round-wood merely contains, after 7 months open storage, less than 30 g per ton of bark or 25 mg per ton of sapwood, depending on the type of insecticide, the bark or sapwood shavings may be incinerated normally, according to less severe legal prescriptions than for ...

Sawn timber of fir (Abies alba Mill.) - Treatability and usability for the Hazard Classes 3 and 4
1999 - IRG/WP 99-40147
Within a national research project, tests on the treatability on sawn timber of fir (Abies alba Mill.) in oscillation pressure, vacuum pressure and double-vacuum processes have been worked out with 95 trunks taken from 3 different altitude levels (up to a height of 590 metres, 600 to 990 metres and over 1000 metres) and from 4 different regions of Switzerland. As the treatability of round wood can...

Recovery of copper, chromium, and arsenic compounds from the waste preservative-treated wood
1991 - IRG/WP 3651
In Japan, about 40 percents of waste wood is incinerated and the residue is dumped into the landfill site. The waste preservative-treated wood, which is mixed in nontreated wood, is incinerated in the same way, too. However, it will cause the serious problems that the gases contained with high concentration arsenic compounds are discharged from the smokestacks of the incineration facilities and th...

During the last COIPM Meeting, up to date information on cooperative work to test the resistance of plastic wrapping for pilings were submitted and discussed. In 1986 untreated wood samples wrapped with shrinkable polyolefin sleeves were submerged in 9 stations, situated in temperate and tropical waters. After 1 or 2 years of immersion the samples showed no sign of penetration by marine borers and...

Technologies for the Management of Wood Waste Containing Metals-Based Preservatives
2005 - IRG/WP 05-50224-16
Disposal of the metals from preservative treated wood can occur through two general strategies: “removal and confinement” or “dilution”. The acceptability of each of these two choices is typically dictated through the disposal regulations of a particular region. A considerable amount of research has been conducted to develop new and innovative “removal and confinement” technologies...

Development of a commercial-scale CCA chemical sludge recycling system
1993 - IRG/WP 93-50001-19
The occurrence of fixation reactions in Copper Chromium Arsenate (CCA) treatment solutions is increased where the treatment of unseasoned and partially seasoned timbers in hot climates occurs. The by-products of the fixation reactions are predominantly insoluble chromium arsenate compounds, commonly referred to as CCA sludge. Historically, this material has been disposed of into toxic waste landfi...

Biological control in termite management – the potential of nematodes and fungal pathogens
2004 - IRG/WP 04-10521
A brief overview on the options for biological control of termites is presented. Many organisms have been identified as being able to kill termites, however, we do not know their real impact on field populations of termites. Most research has focused on some entomopathogenic nematodes and the fungi Beauveria bassiana and Metarhizium anisopliae. To date, only a limited number of field studies have ...

Estimating the age of subterranean termite attack and damage in buildings
2010 - IRG/WP 10-10727
This paper describes physical and experimental methods and a mathematical model (Rotramel 2003) to assist in estimating the age of subterranean termite attack and damage to building structures. Timber, building and termite management industries have to develop new strategies to assess and estimate termite attack and damage in the current climate of global warming. A case study will be used as an e...

Metal Migration from Douglas-fir Poles Treated with Ammoniacal Copper Zinc Arsenate According to Best Management Practices
2010 - IRG/WP 10-50272
The potential for migration of metal components from ammoniacal copper zinc arsenate treated (ACZA) poles was examined using pole sections treated using Best Management Practices. Copper and zinc levels were highest in runoff collected following the first rainfall events, then declined. Copper and zinc levels in runoff averaged 20 ppm and 5 pm respectively. The metal levels were then used to pr...

Phytosanitary standards and the potential for acceptance of chemical treatments as a phytosanitary measure
2011 - IRG/WP 11-30558
Regulations governing international trade in forest products must balance the economic and social benefits of trade with the potential risks of transporting invasive species. The International Plant Protection Convention (IPPC) is an international agreement intended to manage this process. It develops international phytosanitary standards (ISPMs) that are recognised by the World Trade Organisation...

Managing termite risks – An Australian perspective and a cautionary tale
2012 - IRG/WP 12-20482
The management of the risks of termite attack on new buildings in Australia falls to a range of agencies and is mostly achieved through controlling the process by which structures are certified as complying with the Building Code of Australia. Australian Standard AS3660 parts 1, 2 & 3 have historically been the core of this function but now the Building Codes Board's own certification scheme,...
