Termatrac: microwave technology for non-destructive detection of insect pests in timber
2002 - IRG/WP 02-20253
Termatrac is a microwave instrument that has been developed in Australia to detect termite movement within timber and wall cavities. We present data from an investigation into the usefulness of the instrument in detecting drywood and subterranean termites in timber. The West Indian drywood termite Cryptotermes brevis (Walker) was detected in a wooden chair. The subterranean termites Coptotermes ac...

Protection and efficient utilization of plantation grown lesser-known timbers of arid region in India - Acacia tortilis, Prosopis juliflora and Prosopis cineraria
2005 - IRG/WP 05-40321
The plantation-grown timbers are highly susceptible to insects/pests, borers and wood rot fungus. Wood preservatives copper chrome arsenic (CCA) 2% and chloropyriphos 2% solution treated under pressure on three plantation grown timber species viz. Acacia tortilis, Prosopis juliflora and Prosopis cineraria have shown encouraging results in enhancement of shelf life by protection of wood against woo...

A study on insect pests and preservation of fire-damaged timbers in Da Xing An Ling forest region
1991 - IRG/WP 1499
Investigated insect pest of timbers of Da Xing An Ling forest region by means of sampling inspection. Meanwhile we had researched insects pest situation, regularity occurred and biological nature for fire damaged timbers attacked in the log yard. The results showed that the mainly insect species are small black-marmorated longicorn (Monochamus sutor L). We had eagaged in various small tests of tim...

Addition of boron compounds and octanoic acid for improvement of biocidal properties and copper fixation at copper-ethanolamine based wood preservatives
2006 - IRG/WP 06-30408
Copper-ethanolamine based wood preservatives became important active substance (formulation) for wood protection, novelty. As copper itself can not ensure sufficient protection against wood destroying organisms and fixation in wood we combine it with other biocides like ethanolamine, boron and octanoic acid. This investigates were performance on spruce wood impregnated with different combination o...

ISPM No. 15 and the Incidence of Wood Pests: Recent Findings, Policy Changes, and Current Knowledge Gaps
2011 - IRG/WP 11-30568
Largely as a result of international trade, hundreds of species of bark- and wood-infesting insects have become established in countries outside their native range. Many of these exotic insects have caused severe economic and environmental impact to urban and forest trees in the receiving countries. Most bark- and wood-infesting insects have been transported to new countries by means of the wood...

Pest and pathogens threaten the sustainability of plantation forestry: Global research collaboration will define the future
2018 - IRG/WP 18-50341
Global plantation forestry is dominated by intensively managed stands of Pinus, Populus, Acacia and Eucalyptus species. The greater proportion of these plantations has been established in areas where the trees are non-native and have thus been separated from their natural enemies. In all documented cases, these plantations have initially been free of serious pest and disease problems. But as ti...

They might be boring: pests of timber-in-service deserve more attention
2023 - IRG/WP 23-11007
Insects affecting timber-in-service, particularly bostrichid borers and termites, are among the most frequently intercepted organisms at international and national borders, associated with wood packaging, wooden furniture and artefacts, and timber and timber products. There are more than 25 non-native insect species in the Bostrichidae, Ptinidae, Cerambycidae and Kalotermitidae, and at least 12 no...
