Marine exposure assessment of the natural resistance of a number of lesser known species of tropical hardwoods to teredinid and limnoriid borers
2004 - IRG/WP 04-10520
Naturally durable species of timber are used as an alternative to preservative treated timber for marine structures, but many species have not been evaluated for their potential for use in this environment. EN 275 specifies a 5-year test period - too long a period for screening tests to be economically viable. In this study, candidate timber species were selected for testing in the sea on the basi...

Respiratory response of the wood boring teredinid, Lyrodus pedicellatus (Quatrefages) to copper stress
2004 - IRG/WP 04-10528
Wood boring teredinid molluscs engulf most of the wooden particles scrapped by them while actively boring into wood, obtaining nourishment for their metabolic activities. In order to protect the wooden structures from the biodeteriorating activity of such organisms, the wood is treated with different chemical formulations to prolong their service life. Copper chrome arsenic (CCA) is one such woo...

The natural durability of five Indonesian timber species against marine borers - A field test in Indonesia
1981 - IRG/WP 474
This paper presents results of a natural durability field test using five species of Indonesian timbers against marine borers. An attempt is also made to assess any difference in durability between the lower and upper part of the trunks. Results of marine fungal identification, soft-rot assessment, and marine-borer assessment of CCA-treated test blocks will be reported in separate papers...

The natural history of teredinid molluscs and other marine wood borers in Papua New Guinea
1975 - IRG/WP 410
The teredinids, commonly known as teredos or shipworms, are bivalve molluscs adapted to boring into wood. They are most closely related to the Family Pholadidae, or piddocks, which bore into mud, stone and coral. The teredinids have a relatively small, hemi-spherically shaped shell, the elongated body extending beyond the posterior end of the shell valves. The soft body, protected by the wood and ...

Silica treatments to protect timber from marine borers
2001 - IRG/WP 01-30270
Siliceous timbers such as turpentine (Syncarpia glomulifera) are highly resistant to certain marine borers. Attempts to mimic this resistance by chemical treatment however, have met with limited success. This paper describes the impregnation of Pinus radiata and eucalypt timber specimens with organo-silicate formulations. The treated timber gains a pattern of resistance to marine borers that appro...

Marine exposure assessment in southern Portugal of the natural resistance of a number of lesser known species of tropical hardwoods to teredinid and limnoriid borers
2007 - IRG/WP 07-10614
Naturally durable species of timber are used as an alternative to preservative treated timber for marine structures, but many species have not been evaluated for their potential for use in this environment. EN 275 specifies a 5-year test period - too long a period for screening tests to be economically viable. In this study, candidate timber species were selected for testing in the sea on the basi...

Reducing successful settlement by shipworm larvae on wood that has been modified using furfurylation
2023 - IRG/WP 23-11017
Shipworms are Teredinid bivalves that have a highly modified shell for boring into wood and an elongated, vermiform shape. Teredinids are marine wood-borers, utilising timber as both shelter and as a source of food. Wooden structures in the sea, such as piers and sea defences, are subject to severe damage by these borers, costing billions per year for maintenance and replacement. Traditionally, br...
