Does Limnoria lignorum (Rathke) or other cold-water xylophagous limnoriid species exist in southern oceans?
1989 - IRG/WP 4152
The question is posed whether the cold-water limnoriid wood borer Limnoria lignorum (Rathke), or any other such cold-water limnoriid exists in southern oceans. The evidence of collections from various high latitude southern coastlines is cited and the singular absence of any cold-water limnoriid borer noted. The need for further. and possibly extensive, searches for such borers is stressed. i.e. i...

Dominant genera of fungi isolated from the surfaces of Sugi (Cryptomeria japonica D. Don) heartwood lumbers exposed at six test sites from northern to southern regions of Japanese islands
1999 - IRG/WP 99-10304
The surfaces of wood materials are disintegrated not only by sunlight and rainwater but also by microbes when exposed above ground condition. This paper deals with the investigation of fungi isolated from the surfaces of Sugi heartwood lumbers (W100 by T10 by L300 mm) exposed at an angle of 45° without ground contact for 16 months at the six test sites from northern to southern regions of Japan. ...

Drywood termites in the Azores: Problems and tentative solutions
2009 - IRG/WP 09-10698
The detection in 2002 of drywood termites in the islands of Azores has became an urgent issue to be coped with given the fast degradation that structural elements can show after a short period of installation of a colony. A recent study indicates drywood termite presence in about half of the buildings of the historic centre of Angra do Heroísmo (a World Heritage site) in Terceira Island and timbe...
