Development of novel techniques for evaluating the feeding rate of Limnoria lignorum with specific reference to temperature influences
1999 - IRG/WP 99-10325
The faecal pellet production of Limnoria lignorum placed into repli-dish chambers containing seawater and a small chip of untreated Corsican pine (Pinus nigra) was observed. The repli-dishes were kept at a range of constant temperatures between 10 and 25°C and the number of faecal pellets produced by each of the animals was monitored. It was found that faecal pellet length generally increased wit...

Molecular studies on isolates of Serpula lacrymans
1989 - IRG/WP 1421
The major protein species present in detergent extracts of 14 different Serpula lacrymans isolates have been compared, by sodium dodecyl sulphate polyacrylamide gel electrophoresis (SDS-PAGE), with a standard strain, viz. Serpula lacrymans FPRL 12C. Following silver staining of SDS gels the major protein species identified in 12 isolates were similar to those found in the standard strain. However ...

The rate of redistribution and loss of leachable preservatives under service conditions
1993 - IRG/WP 93-30026
This paper describes experiments carried out to determine patterns of preservative redistribution and any associated losses which occur when wood containing unfixed water-soluble wood preservatives is exposed to service conditions where leaching is possible. Scots pine sapwood treated with disodium octaborate was used as a model system. Results are recorded and discussed for trials representing pa...

The performance of wood preservatives in soil-bed soft rot tests
1993 - IRG/WP 93-20007
Testing the efficacy of wood preservatives in soil is recognised as a fundamental part of the assessment of long-term wood protection in ground contact. Laboratory based tests can provide a hazardous environment in which a preservative can be challenged by a range of micro-organisms. This paper presents the results of tests carried out to investigate the performance of wood preservatives in a wet ...

The interaction of polyflavonoid tannins with CCA in Pinus radiata
1987 - IRG/WP 3422
Polyflavonoid tannins complex easily and rapidly with metal ions such as copper, chromium, and arsenic. such complexes in high-tannin-containing CCA treated hardwoods might result in essentially under-treated timber. Four aspects of this interaction were investigated: 1) The relationship between tannin contents of seven hardwoods (Betula pendula, Alstonia scholaris, Fagus sylvatica, Liquidambar st...

Report on marine borer attack on some timbers treated with CCA wood preservative and exposed for three months in sea-water
1985 - IRG/WP 4112
Destruction of timbers by marine borers has long been a problem for the coastal population of Thailand. The use of heavy durable timbers with frequent maintenance, or total replacement, is the only solution for fishermen with their fishing craft or marine installations, meanwhile wharves or other large scale constructions are usually made by using concrete pilings or concrete casings. In recogniti...

Effect of methylene bisthiocyanate on morphology and ultra-structure of a sapstain fungus, Ophiostoma floccosum
2003 - IRG/WP 03-10471
In vitro effects of methylene bisthiocyanate (MBT) on hyphal morphology and ultrastructure of Ophiostoma floccosum were examined using differential interference contrast, epifluorescence and transmission electron microscopy (TEM).
Differential interference contrast microscopy suggested that MBT caused rapid changes to the morphology of O. floccosum resulting in excessive formation of vacuoles and...

Response of laboratory groups of Reticulitermes speratus (Kolbe) to different quantities of food
2003 - IRG/WP 03-10489
As part of a project aimed at improving understanding of the foraging biology of Japan’s most widespread wood-destroying termite, different sized groups of Reticulitermes speratus (0.5; 1 and 2 g) from two colonies were kept on 16 or 64 cm3 of sapwood of Cryptomeria japonica for 12 weeks in the laboratory. Patterns of wood consumption, wood consumption rates and survival are discussed....

Framework document for an international code of good practices for wood preservation and wood protection (anti-sapstain) facilities
1992 - IRG/WP 92-3683
At the Kyoto meeting, the Health & Safety committee agreed to form a task force to prepare a global plan for writing a code of good practices (Code) for wood protection and preservation facilities (Doc. No. IRG/WP/3681). The Canadian document had been presented to the IRG group earlier (Doc. No. IRG/WP/3447) and similar documents were solicited from other countries for preparing a framework do...

Above ground testing of wood preservatives - some experiences from Sweden
1995 - IRG/WP 95-20079
Field stake tests for the evaluation of wood preservatives have been used for more than 50 years in Sweden. In the Nordic countries a system for approval of wood preservatives, which includes field test, has also been in operation for more than 25 years. This system has been described in an IRG Document by Henningson & Jermer (1988). The Nordic system is now in a process of harmonization with ...

IRG/COIPM INTERNATIONAL MARINE TEST - to determine the effect of timber substrate on the effectiveness of water-borne salt preservatives in sea-water: Final report
1987 - IRG/WP 4133
Three timbers chosen as reference species were treated with 3, 6 and 10% solutions of CCA and CCB preservatives and exposed for up to 93 months at 8 tropical and temperate marine sites. Eleven local species treated in the same way were exposed at 4 of the 8 sites. There was no apparent difference in performance between CCA and CCB treated specimens. The severest test site was Panama Canal but mari...
