Biodeterioration and preservation of rubberwood (Hevea brasiliensis)
1994 - IRG/WP 94-10084
Plantation-grown rubber trees (Hevea brasiliensis) in the tropics is fast emerging as a significant provider of quality hardwood for a variety of non-structural products, as the aesthetics of the timber is its creamed colour resembling perhaps the priced but depleting Ramin wood or even American beechwood. However rubberwood logs and sawn materials are highly sensitive to sapstain, fungal decay an...

Bibliography of organic solvent based wood preservatives
1971 - IRG/WP 38 E
This publication has as its objective the collection of the more important and more recent references dealing with solvent-based timber preservatives; these are often termed - sometimes wrongly - oil-borne preservatives or even organic wood preservatives. It is hoped that this review will stimulate more fundamental studies in the future in this field or on some of its aspects....

The benefits to New Zealand of boron salt treatment of Pinus radiata
1992 - IRG/WP 92-3692
The historical reasons for New Zealand adopting boric salt diffusion of Pinus radiata are summarised, and present day processes and their associated costs are given. The biological hazards of using Pinus radiata untreated are then argued, using endemic fungal and insect species as examples, as well as a discussion of the risks from species that may yet be accidentally introduced into the country....

Investigations on the life cycle and nutrition of Criocephalus rusticus L
1974 - IRG/WP 127
The longhorn beetle Criocephalus rusticus L or Arhopalus rusticus (L) is widely distributed in Europe and Asia. It attacks softwoods. The primary host trees are pines, ie freshly felled, unbarked logs, dying standing trees and stumps. After feeding under the bark the larvae enter the sapwood and also the heartwood. Timber to be used for building purposes may be rendered useless by their tunnelling...

Feasibility of AE (Acoustic Emission) monitoring for the detection of the activities of wood-destroying insects
1992 - IRG/WP 92-2416
The feasibility of acoustic emission (AE) as a nondestructive testing method for the detection of the wood destroying insects was investigated. AEs were detected from the wood specimens under feeding attack of sugi bark borers or powder-post beetles. However, the feasible monitoring area of an AE sensor is influenced by the attenuation of AE amplitude, so that this could be a problem in the practi...

Bifenthrin, a new insecticide for the control of termites and wood-boring insects
1995 - IRG/WP 95-30076
Bifenthrin, a new insecticidal compound Bifenthrin has been extensively tested, to determine its potential use to control termites and other wood destroying insects. Bifenthrin is effective at extreme low rates which can minimize human and environmental exposure to the product. Results of tests carried out by several research institutes and by FMC in different countries will be presented. The phys...

The more important wood-destroying insects found in buildings in Poland
1974 - IRG/WP 128
In the different regions (voievodships) of the country Anobium punctatum and Anobium pertinax were to be found in the range of 47.7 to 63.5%. These insects were the main pests in urban buildings. In the second place came Hylotrupes bajulus occurring in the range of 25.9 to 45.1%. The other insects were to be found within the limits of 0.1 to 10.0%; only in a single instance did the amount reach 24...

Remedial treatment of wood attacked by insects
1981 - IRG/WP 3175
A review is presented of remedial treatments against wood-boring insects in wood in service. Preconditions and fundamental principles of insect control are compared with the control of fungal attack and reasons are given for the fact that remedial treatments against insects are more commonly applied than against fungi. With regard to insect control measures with a simultaneous preventive effective...

List of wood-destroying fungi in Iran
1976 - IRG/WP 138
This list gives information on the wood-destroying fungi collected in the Iranian forests and from felled logs and boards in sawmills until now. They are mainly from the region of the Caspian Forests and from the climatically dry region between Teheran and Azarbaidjan, North Iran. It is understood, that this document may help to give more knowledge outside the country about the specific problems o...

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...
