Evaluating the Exterra Termite Interception and Baiting System in Australia
2003 - IRG/WP 03-20267
The Exterraä Termite Interception and Baiting System (Ensystex Inc., Fayetteville, NC) was evaluated in a field experiment near Townsville, Australia. Cellulose-acetate powder containing either 0.05% weight/weight (w/w) or 0.25% w/w chlorfluazuron (Requiemä) was tested for its efficacy in eradicating colonies of the mound-building subterranean termite Coptotermes acinaciformis (Froggatt). Thirte...

Termite baiting system: A new dimension of termite control in the Philippines
2007 - IRG/WP 07-10608
The performance of a baiting system and efficacy of an insect growth regulator (IGR), chlorfluazuron, was evaluated against three economically important species of subterranean termites in the Philippines i.e., Coptotermes vastator Light, Microcerotermes losbañosensis Oshima and Macrotermes gilvus Hagen. Preliminary tests were conducted on secondary nests of M. losbañosensis and mounds of M. gil...

Laboratory evaluation of four benzoylphenylureas against two species of Reticulitermes Holmgren, 1913 (Isoptera: Rhinotermitidae) from Southwest Europe
2008 - IRG/WP 08-30472
The use of benzoylphenylureas in baits for the control of termite pest is currently increasing. The chemical compounds used have been tested mainly with American termites. The effectivity against non-American termite species must be analyzed because the worldwide use of those compounds. In this paper four benzoylphenylureas (hexaflumuron, diflubenzuron, triflumuron and noviflumuron) have been test...

Environmentally Sustainable Method of Termite Management using a baiting system: A case study in the Philippines
2016 - IRG/WP 16-50317
Environment and sustainability are key words for achieving product and business success. Use of chemicals in human vicinity such as homes and buildings are on the increase, thanks to a growing consciousness on pests. Using chemical insecticide is the main stay to counter these pests, but its role in environment is being scrutinized.Insect baiting technology has proven its success around the world ...

Status of the research and development of a new preservative system (EFPL) for pressure treatment of spruce in Canada
1975 - IRG/WP 348
Our work has been to develop a system which would have the stability of the ACA system and the formulation flexibility of the CCA system enabling properties such as fixation of arsenic, water repellency, appearance and cost to be controlled. Our permeability studies of spruce using a method previously developed indicated that an ammoniacal solution of copper arsenate is an excellent candidate for ...

Physical barriers and bait toxicants: The Romeo and Juliet of future termite control
1991 - IRG/WP 1503
Soil chemical barriers are considered by some to be the most important technique for protecting buildings against subterranean termites in Australia (and elsewhere), providing a barrier against termite penetration. However, there is no such thing as a barrier that is 100 per cent +protective. And given the worldwide problems of using organochlorine termiticides, public awareness of chemical pollut...

Evidence supporting the use of termite baiting systems for long-term structural protection
2000 - IRG/WP 00-10377
The efficacy of the Sentricon Colony Elimination System containing Recruit II termite bait (0.5% hexaflumuron) in controlling active subterranean termite infestations has been demonstrated in numerous studies. This baiting system and other termite baiting systems are now widely used, and generally accepted, tools for remedial termite control in North America, Hawaii, and other parts of the world. ...

Baiting techniques for subterranean termite control
1983 - IRG/WP 1205
The use of artificial baits, with and without toxins, have proved effective in attracting large numbers of non-mound and mound building subterranean termites in both urban and rural areas. An outline is presented of a termite baiting program which emphasises concurrent laboratory and field investigations on termite ecology, behaviour and physiology...

Treatability of plywood containing intermountain Douglas fir veneers
1982 - IRG/WP 3203
Eighteen sheets of plywood were obtained which contained intermountain Douglas-fir veneers from two regions of British Columbia. Following pressure treatment with chromated copper arsenate (CCA type C) and ammoniacal copper arsenate (ACA) the preservative penetration and retention in individual veneers was assessed. It was concluded from the study that the intermountain Douglas-fir veneer could no...

Système informatisé d'aide à la décision pour la gestion de la migration du pentachlorophénol dans l'environnement
1993 - IRG/WP 93-50001-10
This paper describes a Decision Support System (DSS), concerning pentachlorophenol (PCP) migration in the environment. The principal objectives of the DSS are to assist managers in siting of PCP-treated poles in the Hydro-Québec system and the storage areas and in the treatment of customer complaints. Four mathematical models are incuded in the system: a model simulating migration inside and on t...

An Historical Roof Timber System in the Old Town of Berlin-Spandau
2019 - IRG/WP 19-10949
In Europe the “Charter of Venice” was enacted on the 31st of May 1964. It is the international directive for the preservation of historic buildings and monuments. All countries in Europe now involve professional wood scientists and engineers in maintaining and preserving historical buildings. Here we discuss a restoration project involving 17th century roof timbering. This project may be used ...

Less environmental impact of wood preservatives by considering the risk of attack in addition to the hazard class system
1995 - IRG/WP 95-50040-10
Hazard classes, which are standardized in Europe in EN 335, are most useful to direct chemical wood preservation towards the organisms which may attack wood in the various fields of utilisation. However, hazard only signifies the fact that an attack may occur without considering the actual risk to attack. To minimize the application of chemicals with respect of less environmental impact it is nece...

Detection of Acoustic Emission (AE) generated by termite attack in a wooden house
1999 - IRG/WP 99-20166
Recently, considerable attention has been paid to methods for termite control, which involves few or no chemicals. To reduce the amount of termiticide needed, it is necessary to detect termite attack in wood as early as possible. The feasibility of acoustic emission (AE) monitoring for the nondestructive detection of termite attack has been discussed previously. In this study, we propose some tech...

Colony elimination of Reticulitermes speratus (Kolbe) (Isoptera:Rhinotermitidae) by bait system
1997 - IRG/WP 97-10189
Following a two-year estimation of the foraging populations and territory of Reticulitermes speratus (Kolbe) by triple mark recapture program at Uji campus of Kyoto University, bait stations (commercialized products containing hexaflumuron) were set up in the foraging territory in October 1995 to eliminate the colony. Inspections demonstrated that the number of test stakes with foraging termites d...

Feasibility study for a dedicated pressure treated wood waste management system
2005 - IRG/WP 05-50224-22
For the creosote treated wood coming out of service, it has been estimated an amount of 200 000 t per year for the next twenty years, and 100 000 t per year afterwards. With a limited number of actors, mainly SNCF (as producer and as user), no importations, and available energy recovery options, it appears possible for setting a dedicated wood waste management system, if the SNCF agrees to. For t...
