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...

On the Influence of Wood Destroying Fungi on the Feeding Intensity of Termites
2017 - IRG/WP 17-10893
The baiting and feeding stimulating effect of wood attacked by fungal isolates of the species Coniophora, Lentinus, Poria and Gloeophyllum on termites Reticulitermes santonensis is examined. There are significant relationships between the activity of fungal isolates and the feeding behaviour of termites. The most active isolates can be used for increase the attractiveness of wood to wood-destroyin...

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...

Studies on the destruction by marine wood boring organisms of fishing boats in the Eastern Black Sea of Turkey
1977 - IRG/WP 427
The present paper concerns the problem of fishing boats which are attacked by wood boring organisms in the Black Sea of Turkey. The aims of this study are: 1) to identify the marine wood boring organisms attacking fishing boats in the Northern Black Sea of Turkey; 2) to identify the wood species that are used in boat building construction and assess their durability; 3) to assess the degree of att...

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...

Comparison between agar-block and soil-block methods for wood-destroying Basidiomycetes
1992 - IRG/WP 92-2401
The object of this work is to compare these methods in order to provide some information to help in the choice between them. The comparison was made by a statistical analysis (factorial completely randomized design) and by a discussion about other aspects of each method. An evaluation of some fungi on attacking wood and a comparison between Picnoporus sanguineus isolated from carpophore and decaye...

Wood preservation in Kenya
2000 - IRG/WP 00-40190
Focussing an Wood Preservation in Kenya, the Report discusses and elaborates on Education and Training, Research, Wood deteriorating organisms, Treatment Plants and Processes, Preserving Chemicals, Specifications, Markets, Health and Safety and Environmental issues. Education and Research is limited to one Institution only, other Institutions involved with the properties and utilization of wood ha...

Proposals for further co-operative studies on determining toxic values against wood-destroying basidiomycetes (1988)
1988 - IRG/WP 2316
This document sets out proposals for a further series of co-operative tests, based on previous discussions. A basic soil/block test is proposed, to be carried out by all participants using one preservative and four test fungi. Optional additional tests may be carried out using a range of other media (agar, vermiculite, rockwool) additional fungi of choice, additional preservatives of choice and pr...

Description of a trial with wood preservatives against marine wood boring organisms
1975 - IRG/WP 412
Wood situated in sea water along the Atlantic coasts of the Nordic countries is attacked by marine wood boring organisms. Timber constructions in these waters therefore must be preservative treated. In order to evaluate the effect of various preservatives against marine wood borers, the Nordic Wood Preservation Council (NWPC) organized a rather extensive trial in 1972. In the absence of and while ...

Vertical distribution of fouling and wood-boring organisms in the Trondheimsfjord (Western Norway)
1981 - IRG/WP 476
Results of a detailed study on the vertical distribution of fouling and wood-boring organisme of Trondheimefjord at an interval of 3 m from intertidal level to a depth of 30 m, has been presented, based on data collected from two series of panels, exposed from 15-3-1977 to 15-7-1977 (Series I) and from 22-7-1977 to 13-3-1978 (Series II). The intensity of fouling generally decreased with increasing...

Unsuitability of the limiting dose as a criterion for assessing the toxicity of preservatives to wood-destroying fungi
1974 - IRG/WP 243
In the majority of methods for investigating preservatives for wood-destroying fungi their toxicity is assessed by determining what is called the "limiting dose". This normally denotes a range of preservative solution concentrations or retentions of dry preservative in the timber, the lower value serving to indicate the amount of preservative at which is observed the expected effect, e.g. the grow...

Lethal temperature for some wood-destroying fungi with respect to eradication by heat treatment
1984 - IRG/WP 1229
The lethal heat dosis as a function of temperature and time of exposure has been tested for mycelium and for wood infested by three strains of Serpula lacrymans and by Coniophora puteana, Poria monticola, Paxillus panuoides, Gloeophyllum trabeum and Gloeophyllum sepiarium. Even for Serpula lacrymans, which is well known for its sensivity to heat treatment, 30 min at 55°C were necessary to kill th...

Document IRG/WP/2194 reported the status of the programme of co-operative experiments up to and including December 1982. During discussions at IRG-13 in Turkey members endorsed the decision to complete the programme of tests and conduct repeat tests.

Reinfestation of consolidated ancient wood by insects
1998 - IRG/WP 98-10290
Wooden artifacts are often attacked by wood-destroying insects. Therefore conservators have to stabilize numerous objects from such attack. Initially we studied the resistance of painting materials and consolidants on unaffected recent wood against wood-destroying insects (IRG/WP 97-10239). Further, we wanted an answer to the question: Are artifacts, formerly destroyed by wood-borers, reinfested b...

Non-destructive detection of the presence and behaviour patterns of wood-destroying insects
1988 - IRG/WP 2302
An apparatus, designed for the automatic recognition of the presence and of specific behaviour patterns of wood-boring insects, is introduced. From a wood sample, a mixture of noise and action induced substratum vibrations is picked up, amplified, filtered and translated into a sequence of computer-readable numbers which are passed to a microcomputer-based signal-pattern-recognition. If an incomin...

Study of the degradation caused by micro-organisms in Pinus sp. waterlogged wood
1989 - IRG/WP 1411
So far, the different Centers are trying the restoration and the conservation of wood structures, coming from subaquatic archeological deposits, with interest from the historic - artistic point of view. The main objective of this paper has been the determination of the decay level of Pinus sp. wood coming from a roman ship (approximately 2000 years old), where we have analyzed their physical prope...
