Über den Nagekäfer Oligomerus ptilinoides (Wollaston), Col., Anobiidae: Verbreitung und Einschleppung, Bestimmung, Lebens- beziehungen und Befallsmerkmale mit Vergleichen zu Nicobium
1980 - IRG/WP 1102
Oligomerus ptilinoides occurs in the Mediterranian and Black-sea area, in North-Africa and Asia minor as an important pest causing severe damage to dry wood. By travelling, by the immigration of people from south to north, and by accidental introductions the species tends to establish itself north of the Alps. Severe damage has recently been observed in two museums. An account is given of aspects ...

The status of Anobium punctatum and Hylotrupes bajulus in buildings in the United Kingdom
1993 - IRG/WP 93-10039
Anobium punctatum and Hylotrupes bajulus are the two most significant insect pests of structural timber in the UK. This paper describes the results to date from two separate surveys in the UK carried out by the BRE in collaboration with remedial treatment companies, local authorities and building societies to establish the incidence and status of these insects with respect to geographical location...

Acoustic communication between Microcerotermes crassus Snyder
1982 - IRG/WP 1158
An unusual acoustic communication within a nest of Microcerotermes crassus SNYDER is reported. The signals produced by the termites are described and possible reasons for this behavior are considered....

Screening-method for the examination of the resistance against contact-insecticides of Lyctus brunneus Steph. beetles
1981 - IRG/WP 2148
A serie of filter-paper rondelles is treated with different concentrations of an organic insecticide dissolved in aceton. Beetles of Lyctus brunneus are put onto the dry surfaces. During the impact of the poison the knock-down is observed and after a following poisonfree holding, the knock-down and mortality are registred....

On the occurrence of the Australian Lyctus parallelocollis Blackburn in Israel and how to distinguish from Lyctus brunneus (Steph.)
1978 - IRG/WP 194
In June 1976 attacked plywood was sent from Tel Aviv for determination of the insects concerned. An unknown Lyctus species and the asiatic Heterobostrychus aequalis (Waterhouse) were responsible for the damage. Further material sent by Dr. J. Halperin, Forestry Division, Ilanoth, in September 1976 and beetles of his field collection in 1977 revealed this Lyctus sp. to be a rather widely distribute...

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...

Proposal for co-operative work. Testing the ability of accidentally introduced tropical insects to survive the cold season in Europe
1976 - IRG/WP 155
By hibernation-experiments in the past it was found that not only the low temperatures may become fatal by freezing. In some experiments we found indications that larvae died by starvation. For example Lyctus africanus-larvae did so in some years with a cold winter (mean above 0°C). If you like to take starvation as a reason for death into account it may be useful to withdraw pieces of infested w...

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...

An investigation concerning Camponotus spp. distribution and damage in buildings in Sweden
1985 - IRG/WP 1248
This is a report of an investigation by a Swedish insurance company on the occurrences of damage by Carpenter ants during 1974 to 1981. The distribution of damage in walls, roofs and floors of both permanent homes and summer-houses has been assessed. It is concluded that the increased frequency of attack is becoming economically serious....

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...

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...

Supercooling points of Anobium punctatum, the common furniture beetle
1995 - IRG/WP 95-10120
Ice formation within the body of larvae of the common furniture beetle Anobium punctatum causes death of the larvae. Freezing can therefore be used as a means of eradication of the larvae in infested wood. To optimize the freezing process, knowledge of the temperatures sufficient to kill the larvae is essential. Ice formation is initiated by temperatures equaling the so-called supercooling point, ...
