Natural Durability Classification Systems Used Around the World
2009 - IRG/WP 09-10694
Around the world natural durability is classified in different ways. The nature and rigor of the tests used to measure durability, the method of classification based on these data, and use of these classifications to specify end uses or predict service life all vary. This can lead to confusion among people not familiar with the various systems used. This review describes the methods used to classi...

Termite control in the post-organochlorine era: How do we advise industry and society?
1990 - IRG/WP 1435
Organochlorines have been severely restricted and banned in many States in North America, and replaced by organophosphates and synthetic pyrethroids. This situation may occur in Australia, and elsewhere, in the not too distant future. Just how do we as entomologists advise the industry and society in termite control in the post-organochlorine era? A brief historical overview of pesticide bans and ...

Creosote for wood preservation
1971 - IRG/WP 36
By creosote one usually means coal tar creosote, although there are creosotes of other origin. For example, wood tar creosote is a product of wood distillation. It is, in fact, in this connection that the word 'creosote' was first used. Early in the nineteenth century the oily product obtained by distilling wood was said to have an odour which resembled 'smoked meat&...

A rapid method for collecting large numbers of subterranean termites from wood
1982 - IRG/WP 1165
A corrugated fiberboard trap is described which attracts large numbers of subterranean termites from infested logs. Single-trap collections in excess of 63 grams (wet wt.) for Reticulitermes virginicus (Banks) and 43 grams for Coptotermes formosanus Shiraki were taken one to three days following discovery by termites. If traps are removed from the source logs shortly after beeing attacked, termite...

The natural durability story
1997 - IRG/WP 97-20119
Wood species with superior natural durability were in use since the beginning of timber utilisation. Their importance decreased with increasing industrial timber impregnation. In recent time, however, they gained worldwide new interest due to environmental problems involved with treated timber. In Europe a special Standard (EN 350) has been published and a multinational research project on testing...

Reinfestation of consolidated ancient wood by insects
1998 - IRG/WP 98-10290
Wooden artifacts are often attacked by wood-destroying insects. Therefore conservators have to stabilize numerous objects from such attack. Initially we studied the resistance of painting materials and consolidants on unaffected recent wood against wood-destroying insects (IRG/WP 97-10239). Further, we wanted an answer to the question: Are artifacts, formerly destroyed by wood-borers, reinfested b...
