Comparison of AE-apparatus for detection of activity of Old house borer larvae, including reality check
2021 - IRG/WP 21-10981
As part of the German funded project ‘InsectDetect’ comparative measurements were done with three different Acoustic-Emission-(AE)-apparatus on 14 pine beams in order to assess presence of active attack by the Old house borer (Hylotrupes bajulus (L.)).
In all beams active attack was measured, though in varying intensity. This was corroborated by completely dissecting 10 of the beams. All thre...

Durability of thermotreated Pinus sylvestris and Eucalyptus nitens against wood decay organisms
2022 - IRG/WP 22-40949
One of the alternative treatments to avoid the application of biocides is thermal modification of wood, which increases the durability of wood against attack by wood decay organisms. The durability of Pinus sylvestris and Eucalyptus nitens thermotreated at 180 and 212 ºC, was studied. The results show that thermotreatment against wood decay fungi in P. sylvestris is slightly more effective than i...

Isolation of the microbiota from wood decay insects and some of their enzymatic activities
2023 - IRG/WP 23-11014
Wood decay organisms have the ability to degrade wood components (cellulose, hemicellulose and lignin) by enzymatic capacities, but these enzymes can belong to the proper organism, or to the associated microbiota. The identification of the microorganisms, as well as their role in the digestion of many substrates not always is very well known.
The wood decay insects produce big damages in wood str...

Potential of plant polyphenol extracts in pesticide formulations against Xylophagous insects
2023 - IRG/WP 23-30790
Termite castes (soldiers, nymphs, and reproductives) are unable to feed themselves and are fed via trophallaxis from the workers which degrade the cellulose from wood. It is of great economical importance to ascertain the efficacy of preservatives against wood decay organisms in order to extend wood products service life. Remedial chemical product applications are used primarily as wood treatments...
