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...
Proposing innovative technologies in the control of dry-wood insects
1985 - IRG/WP 1262
This paper discusses the social-economic problems involved in the biological evaluation of dry-wood insects with particular reference to Nigeria. It also discusses prospects of applying non-conventional methods of control against such insects, integrating these with the conventional preservatives as a control strategy. This discussion follows attempts made to identify the major dry-wood insects in...

Preliminary testing of an improvised wood preservative mixture applied against dry wood beetles
1986 - IRG/WP 1308
An improvised wood preservative mixture was preliminarily tested in situ against some dry wood beetles which had infested structural timbers in a semi-finished building. The results obtained should encourage further research towards mobilizing/improvising locally available resources in the face of scarce standard wood preservatives, against the background of a dilemma in wood utilization in the de...

A new type of biocide suitable for use in different fields of wood preservation
1993 - IRG/WP 93-30014
A new type of polymeric biocides was developed containing quaternary ammonium and boron ester groups as active structure elements, to overcome the disadvantages of AAC's in wood preservation use and to utilise their good performance due to a broad efficacy against fungi on the other hand. The new biocides called polymeric betains have been tested in laboratory and field tests and especial...

Penichroa fasciata (Stephens) (Col. Cerambycidae) a pest in wood materials
1988 - IRG/WP 1365
Penichroa fasciata (Stephens) (Col. Cerambycidae) is found to be a frequent pest occurring in hardwood in storage in Italy. This paper reports the characteristic for identification, biological features, distribution and timber liable to attack....

Über Wespen als Holzverderber - Schäden, Ursachen, Bekämpfung
1978 - IRG/WP 189
Observations and a number of actual cases over recent years show that wasps have been associated more frequently with damage to wood. The nature of such damage and the agents involved are as follows: 1. Decay following infestation by Woodwasps (Siricidae). 2. Punctate marks caused by superficial gnawing and also boring into wood by larvae of the Dock sawfly (Tenthredinidae). 3. Damage due to super...
The resistance of painting materials and consolidants against wood-destroying insects
1997 - IRG/WP 97-10239
Natural and synthetic adhesives, varnishes, painting materials and consolidants were used in investigations of bioresistance against newly hatched larvae and beetles of Hylotrupes bajulus (L.). Animal glues, casein, drying oils and natural resins such as dammar resin and shellac, were not resistant to attack by these larvae. Similarly, semi- and all-synthetic polymers tested including hydroxypropy...

Fluorine compounds for wood preservation
1971 - IRG/WP 304
Fluoride compounds have gained a considerable importance in wood preservation, especially in Germany and some other countries of Europe. They are used as single compounde or in mixtures of different compounds. In the International Research Group on Wood Preservation which continues the activities of a former OECD-Group, it was moved to prepare a survey on fluorides in wood preservation together wi...
Wood-destroying insects found in the Eastern Black Sea sub-region of Turkey
1982 - IRG/WP 1153
The Eastern Black Sea subregion has important forest resources. The settlement areas are scattered at the countryside. That's why a good deal of wood and timber is used in the construction of buildings without sufficient protective measures in the rural areas. In the forests and rural buildings 52 wood-destroying insect species have been specified 35 of which are new in this subregion and...

Changed susceptibility of the chemically and thermally degraded spruce wood to its attack by the dry rot fungus Serpula lacrymans
1999 - IRG/WP 99-10322
In buildings, some intentional or unintended situations can occur at which some wood products are exposed to aggressive chemicals and also to higher temperatures. Occasional activity of fungi on such pre-attacked wood products can be either higher or lower. This paper deals with changes in the susceptibility of spruce wood (Picea abies L. Karst.) to attack by the dry rot fungus Serpula lacrymans, ...
Report of an investigation of damage by wood ants in buildings in Sweden
1976 - IRG/WP 148
Wood ants in buildings occur everywhere in Sweden, particularly in maritime districts and in vicinity of larger lakes. The damage caused by Camponotus herculeanus does not differ from that caused by Camponotus ligniperda. The former occurs in all Sweden, the latter only in southern Sweden. The damage is to be found almost exclusively in dwelling houses (week-end cabins and "all-the-year round" hou...
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 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...
