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...

Chemical Analysis of Southern Pine Pole Stubs Sixty Months Following Treatment with a Methylisothiocyanate-Based Solid Fumigant Stick
2019 - IRG/WP 19-30740
Methylisothiocyanate-based fumigants have been commercially used in the United States for over 35 years to control internal decay in utility poles and other wooden structures with little technological advancement. The most recently commercialized methylisothiocyanate-based fumigant is chemically known as dazomet. Dazomet is a free-flowing powder or granule that decomposes in the presence of mois...

Through-boring to improve the performance of low durability Eucalyptus species for utility poles: 10-year field test results of pole stubs exposed in Southeast Queensland
2023 - IRG/WP 23-40972
An impending shortage of naturally durable hardwood electricity pole timbers in Australia has encouraged investigation of alternatives containing less durable, untreatable heartwood. Through-boring or drilling holes perpendicular to the long axis before treatment, has been used successfully on refractory softwood poles in North America and might have application in Australia. The use of through-bo...
