An interim report on studies of the tolerance by Sphaeroma (Crustacea: Isopoda) of CCA-treated timber
1982 - IRG/WP 491
In Papua New Guinea any untreated timber exposed to seawater close to mangrove stands is liable to be attacked in the intertidal zone by the crustaceans Sphaeroma terebrans or Sphaeroma triste. Even CCA-treated timber is sometimes vulnerable. The mouth-parts of these animals are adapted for boring, but whether wood particles are ingested remains to be resolved. Some limbs of Sphaeroma terebrans ap...

Chelura terebrans (Crustacea: Amphipoda) is capable of degrading wood independently of its associate, Limnoria
1992 - IRG/WP 92-4180
Chelura terebans has been reported to be dependent on the tunnelling activities of Limmmoria. However, this study has shown that Chelura is capable of excavating its own grooves in the surface of blocks of the low density hardwood, balsa (Ochroma lagopus). When reared on blocks of balsa, Chelura ingests small wood particles. These particles often show evidence of degradation due to tunnelling bact...

Copper storage in the digestive caecae of Limnoria tripunctata and Limnoria quadripunctata (Crustacea: Isopoda) tunnelling in CCA treated and untreated wood in laboratory cultures
1998 - IRG/WP 98-10257
Digestive tract tissues of Limnoria quadripunctata Holthuis and Limnoria tripunctata Menzies, tunnelling untreated and CCA treated Scot's pine sapwood under laboratory conditions were examined using X-ray microanalysis and transmission electron microscopy. Populations of both Limnoria species tunnelling treated and untreated wood stored copper within their digestive caecae in the form of ...

A laboratory bioassay method for testing preservatives against the marine borers Limnoria tripunctata, L. quadripunctata (Crustacea) and Lyrodus pedicellatus (Mollusca)
1990 - IRG/WP 4159
A laboratory culture and bioassay method is described for the marine borers Limnoria tripunctata, Limnoria quadripunctata, and Lyrodus pedicellatus. The methods were tested in a bioassay using established marine preservatives. The attack produced on blocks treated with CCA or creosote in some ways paralleled the attack found in the sea. Limnoria tripunctata attacked treated and untreated pine bloc...

Effects of wood-inhabiting marine fungi on food selection, feeding intensity and reproduction of Limnoria tripunctata Menzies (Crustacea, Isop.)
1981 - IRG/WP 480
The paper gives a condensed survey on laboratory tests with Limnoria tripunctata Menzies and pure cultures of 9 different marine wood-inhabiting fungi. Limnoria is able to distinguish between fungus-infested and non-infested wood. Wood with dead mycelium mostly proved to be less attractive or even repellent and was initially consumed less than with living fungi. On non-infested wood, initial feedi...

The functional anatomy of the digestive caecae and gut residence times for the marine wood borer Limnoria (Crustacea: Isopoda)
1997 - IRG/WP 97-10204
A scanning and transmission electron microscope study of the digestive caecae of the marine wood boring isopods Limnoria tripunctata and Limnoria quadripunctata, was undertaken. Two cell types were identified, containing structures indicative of absorption, secretion and storage. Cell types were distinguished according to size, the largest cell type having a large free surface area, a well develop...

Fouling and Boring Organisms Deteriorating Various European and Tropical Woods at Turkish Seas
2010 - IRG/WP 10-10741
This study aims to investigate the diversity of fouling and boring organisms damaging wood material at Turkish coasts. Trials were carried out at six harbour sites throughout the seas surrounding Turkey. Wood samples were hanged down at a depth of six meters in the sea, for a period of one year. Identification of the organisms obtained from wood plates revealed the presence of five wood borer and ...
