Timber infesting species of Col. Lyctidae and Bostrichidae imported into Germany since ca. 1985
2000 - IRG/WP 00-10385
This contribution to the knowledge of passively and unintendedly dispersed species of Col. Bostrichoidea has been derived from the author's private investigation in cooperation with German quarantaine institutions from 1996 to 1999. It is a brief summing-up of the importations of timber infesting "Powder-post Beetles" (Col. Lyctidae) and "Borer Beetles" (Bostrichoidae) into a European ind...

Possibilities of improving the oscillating pressure method
1991 - IRG/WP 3668
Studies on the dynamics of pressure changes in wood during impregnation revealed no significant effect of fast pressure changes for green spruce as used by OPM (IRG/WP/3615). The following experiments were carried out on several hundreds of spruce palisades to examine the modification of single procedure parameters of common use OPM and to record the effects on the impregnation result with the aim...

Valid scientific names of wood-decaying fungi in construction timber and their vernacular names in England, Germany, France, Sweden, Norway and Denmark
1992 - IRG/WP 92-1546
The valid scientific names of 100 species of wood decaying fungi in construction timber are listed, the citation of authors' names is standardized, and an index of the most commonly used synonyms is compiled. For each species vernacular names used in England, Germany, France, Sweden, Norway and Denmark are listed. The list of names is an attempt to update the current use of the most impor...

Characteristics and quantity of impregnated wood waste in Germany
1995 - IRG/WP 95-50041
The disposal of wood waste in Germany is one of the main problems not only for the wood preservation industry but also for all concerned with wood waste. Data on characteristics and quantity of wood waste are still needed. Based on criterions given in a previous paper (IRG/WP 93-50006), several assortments have been characterized with regard to their hazardous potential and their logistical aspect...

Wood Preservation in the Federal Republic of Germany
1981 - IRG/WP 3157
The report gives some statistics about the forest products industries in the Federal Republic and a general review of the wood preservation industry. The trend in the use of wooden railway sleepers is decreasing, as is the use of poles. The sale of other pre-treated timber, mainly fence posts, palisades and domestic fences, is however slightly increasing. Apart from the use of pressure treatments ...

Moisture content and other tested values in. Double layer tests of different size in Lithuania and Germany
2004 - IRG/WP 04-20299
The paper presents measurement results of moisture content and the analysis of durability trial of double layer wood in variants of varying size, conducted in Girionys, Kaunas distr., Lithuania and in Hamburg, Germany. In this trial 3 sample sets of varying size, containing 25, 50 and 100 specimens, are used. The aim of this trial is to ascertain an optimal number of test specimens. The dynamics o...

The waste wood situation in Germany - legislative and practical consequences
1998 - IRG/WP 98-50101-06
Waste wood or 'reclaimed wood' is produced in numerous areas of private and public life, in trade and in commerce, and its re-use is increasingly posing problems in Germany. This development has been reinforced as a result of legislation, such as the Trade Cycle and Refuse Act (KrW-/AbfG), the law regarding the supervision and control of the cross-frontier transportation of waste...

Frequency of fungal decay in softwood windows in Germany
2010 - IRG/WP 10-10725
Knowing how often fungal decay occurs is a fundamental basis for general recommendations of preservative measures. To optimize the German recommendations for chemical wood preservation of windows made out of pine or spruce more than 2000 windows have been inspected. All windows had an opaque coating and were between 2 and 17 years old. The selection of the inspected windows was kept as randomly as...

Occurrence of synanthropic beetles (Coleoptera Ptinidae) and checkered beetles (Coleoptera Cleridae) in relation to climatic factors in historical buildings from North-Eastern Germany
2021 - IRG/WP 21-10980
Predatory checkered beetles occur in many historical buildings. Thus, it is essential to learn more about the ecology of these beetles, specifically for their further use as suitable beneficial organisms in biological control of wood-destroying insects. In this study, indoor climatic conditions were examined as a major factor influencing their occurrence and that of their prey Anobium punctatum an...

Genetic relationships of local infestations by Anobium punctatum, Xestobium rufovillosum and their associated predator Korynetes caeruleus from buildings in North-Eastern Germany
2021 - IRG/WP 21-10982
Wood-destroying pests such as Anobium punctatum and Xestobium rufovillosum cause damage to art and cultural objects as well as to buildings. Monitoring population dynamics of pest species as well as of their naturally occurring counterparts are an essential part in the development of biological control measures as alternatives to conventional wood protection. Therefore, both the dispersal and homo...
