Visualization of Feeding Process of Larvae of the Wood-boring Beetles Using X-ray Computer Tomography
2019 - IRG/WP 19-10953
X-ray computer tomography (CT) was applied to observe the movement of the larvae of the wood-boring beetles Lyctus brunneus, Lyctus africanus, and Heterobostrychus aequalis inside the infested wood specimens. The larvae bred with artificial diet were inserted into the hole of wood specimens of rubber wood Hevea spp. or Japanese oak Quercus crispula. The wood specimens with larvae were scanned usin...

Analysis of larval development and feeding of an Anobiid beetle using X-ray computed tomography
2020 - IRG/WP 20-10961
Priobium sp., an anobiid beetle, can attack wood used for historic constructions in Japan. Its life history and feeding biology, especially larval development and behavior, are poorly understood because the beetles are hidden inside wood most of the time. We used X-ray computed tomography (CT) to regularly scan wood blocks infested with the larvae of the Priobium sp. and observed the process of ...

Validating a short-term laboratory method to assess the resistance of timber to biodegradation by marine wood-borers
2021 - IRG/WP 21-10975
Novel approaches to protecting wood in coastal and marine environments are needed as the use of traditional broad-spectrum biocides are now restricted. Wood is widely utilised in marine environments where it can be rapidly degraded by wood-boring organisms, causing billions of dollars of damage per annum. Biocidal compounds such as CCA and creosote have been popular treatments for timber products ...

Wood modification reduces the feeding rate of the wood boring crustacean, Limnoria quadripunctata
2022 - IRG/WP 22-10993
Adult Adult Limnoria search for new wood once their current piece disintegrates from tunnelling. During this time, they do not have access to wood so experience a period of starvation and must feed again once settled. Wood modification offers protection to marine structures by reducing the feeding rate of Limnoria and therefore can reduce recruitment of adults from distant pieces of wood. Chemical...

Steam Pre-conditioning Treatment Prior to Acetylation: Impact on Dimensional Stability, Moisture Response Behaviour, and White-Rot Fungal Resistance of Hevea brasiliensis and Mitragyna ciliata Wood
2022 - IRG/WP 22-40930
The effect of steam pre-conditioning treatment on the dimensional stability, moisture response behaviour, and durability against white-rot fungus P. chrysosporium of acetylated Hevea brasiliensis and Mitragyna ciliata wood species were assessed. Defect-free specimens of both species from the top, middle, and base positions were selected, prepared according to ASTM D143-09 & ASTM D-2017 standards a...

Moisture sorption behaviour of poplar and thermally modified poplar using dynamic vapour sorption (DVS)
2022 - IRG/WP 22-40947
The moisture sorption behaviour of wood has a critical impact on service life. In Europe, softwood is mostly used to manufacture engineered wood products such as cross-laminated timber (CLT) or glue-laminated timber (GLT or glulam). Yet fast-growing and widespread tree species such as hybrid poplar with or without modification, have potential to meet the increasing demand. This study shows the moi...

Susceptibility of selected Australian commercial timbers to West Indian drywood termite Cryptotermes brevis
2023 - IRG/WP 23-11003
West Indian drywood termite (Cryptotermes brevis) is a globally distributed timber pest and is invasive in Queensland, Australia, causing widespread damage to structures and large economic impacts in control and repair costs. Despite this, the knowledge of which specific timbers are susceptible to attack is limited and requires investigation. Two six-week feeding trials were performed, exposing se...
