Field tests of molybdenum and tungsten baits for termite control
2004 - IRG/WP 04-30345
Molybdenum and tungsten compounds are slow acting to termites and show a high termiticidal efficacy. In our previous papers, we have already reported that those are useful as termiticidal ingredients of bait formulations.
The demand for natural rubber is still on the increase. However some kinds of termites inhabiting rubber plantations damage rubber trees and pose a serious threat.
To cope with...

Computerised data acquisition and barcode technology - Examples of its application and use in wood preservation research
1992 - IRG/WP 92-2404
Experimental samples in wood preservation research are usually individually labelled with either some form of durable marking pen or more commonly with a stamped metal or plastic tag. The label must remain intact and legible for the duration of the experiment which, in the case of a field trial, can be many years. Preservative performance data have traditionally been recorded manually on a data sh...

The UK termite eradication programme: Justification and implementation
2000 - IRG/WP 00-10373
In May 1998, an established infestation of subterranean termites (Reticulitermes lucifugus subsp. grassei) was found in a semi-rural, coastal setting in Saunton, North Devon. Surveys and monitoring revealed a discrete, highly localised infestation extending over some 2400 square metres. There is some evidence that the termites were imported accidentally possibly more than 30 years previously. With...

Laboratory evaluation of disodium octaborate tetrahydrate (TIM-BORÒ ) as a wood preservative or a bait-toxicant against the Formosan and eastern subterranean termites (Isoptera: Rhinotermitidae)
1991 - IRG/WP 1513
A no-choice bioassay indicated that termite feeding was significantly reduced when wood was treated with TIM-BORÒ at retentions of >3600 ppm and >900 ppm (w/w) for Coptotermes formosanus and Reticulitermes flavipes, respectively, and thus these wood preservative retention rates may be considered for these termite species. Results of a choice bioassay suggested retention rates of 450-1800 pp...

Practice Makes Perfect: A Biodeterioration Diagnostics Database that Makes Practice
2008 - IRG/WP 08-10648
Replacement of bio-based materials deteriorated by pests costs billions annually and wastes natural resources. Wood replacement rates have remained relatively stable despite significant advances in wood preservation. This may be explained, in part, by poor end-use by uninformed users and by inadequate pest management once products are in service. This problem may be exacerbated by two opposing fac...

A Review of Wood as Material and Source of Innumerable Products
2008 - IRG/WP 08-10662
As we known that “wood –which is a source of innumerable pruducts (Tsoumis, 1968)– is a fascinating and challenging material (Dinwoodie, 1975)”, and hence, “an understanding of the basic properties of wood and of the factors that affect its serviceability is vital background for the preservation of wood structures (Sherwood, 1986)”. This paper therefore presents an overview of structru...

Wood protection by means of electro osmotic pulsing technology (PLEOT)
2010 - IRG/WP 10-40505
Wood protection is mainly based on chemical protection of wood. The disposal of wood preservative treated material causes restrictions in its later use or recirculation into the eco-cycle. A new protective system, electro-osmotic pulsing technology on wood, called PLEOT, is tested in a fungi test and in soil contact. Mass loss and moisture content of Scots pine sapwood samples was calculated after...
