Do insects infest wood packing material with bark following heat-treatment?
2007 - IRG/WP 07-10633
As a result of international trade, many bark- and wood-infesting insects are inadvertently transported in wood packing materials (WPM) such as crating, dunnage, and pallets. WPM is suspected as the likely pathway for most of these borers, although the exact mode of entry into the USA is unknown for all 25 borers. The top 10 countries of origin were, in decreasing order, Italy, Germany, China, Spa...

The uses of Molecular techniques in studying Australian subterranean termites Genus Coptotermes
2008 - IRG/WP 08-10669
This study focuses on applying molecular tools in studying the phylogeny of the Coptotermes, especially from the Australian region, by using a combined data set of three mitochondrial genes, viz. 16S, COII, COI, comprising a total of about 2000 base pairs.
This study will address these following specific questions:
i. Does molecular phylogenetics reveal any new species and show any previously ...

Australian trials on the efficacy of micronized copper
2008 - IRG/WP 08-30480
Alkaline copper quat (ACQ) is an established wood preservative that is formulated with solubilised copper in amine solvent. This paper describes three separate trials in Australia that investigated whether substituting soluble copper with micronized copper affects performance. ACQ and micronized copper quat (MCQ) gave similar performance in Pinus radiata against four brown-rotting fungi in a soil-...

Review of candidate graded particle barrier testing methods in Australian Standard (AS 3660.3 – 2000): Assessment criteria for termite management systems
2009 - IRG/WP 09-20417
The Australian Standard (AS. 3660.3 – 2000) for assessment of candidate graded particle termite barriers is reviewed and suggestions for amendments are made. Areas requiring amending in light of current biological knowledge involve the inclusion of proprietary or patented systems rather than generic types; selection of test termites in the genus Coptotermes; duration of test periods; and inadequ...

Wood protectors sensitivity of Fusarium circinatum, a quarantine organism in Europe
2011 - IRG/WP 11-10755
In the last decade, two new organisms with a high potential damage in Conifer forests have been detected in Europe. They are the nematode Bursaphelenchus xylophilus and the fungus Gibberella circinata (anamorf: Fusarium circinatum), and have driven the European Union to protect the stands from propagation and dispersion of these new pathogens.
The nematode was detected first in Setubal (Portugal)...

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...

Managing termite risks – An Australian perspective and a cautionary tale
2012 - IRG/WP 12-20482
The management of the risks of termite attack on new buildings in Australia falls to a range of agencies and is mostly achieved through controlling the process by which structures are certified as complying with the Building Code of Australia. Australian Standard AS3660 parts 1, 2 & 3 have historically been the core of this function but now the Building Codes Board's own certification scheme,...

Copper naphthenate treatment for wood pols - a review and update
2012 - IRG/WP 12-30600
This paper reviews copper naphthenate (CuNap) and its utility as a treatment for wooden utility poles. One of the principal reasons that CuNap has gained market acceptance, in addition to its efficacy against decay fungi and wood-destroying insects, is its low mammalian toxicity. CuNap is a well-proven non-restricted use preservative, used extensively and specified for environmental reasons by ut...

Product efficacy against Fusarium circinatum, a quarantine organism in Europe
2013 - IRG/WP 13-10807
Fusarium circinatum Nirenberg et O'Donnell (telemorph: Gibberella circinata Nirenberg et O'Donnell) is a quarantine organism in Europe producing the disease known as pitch canker of pines. For a decade, the European Union has taken steps to locate and eradicate the pathogen with the aim of eliminating the risk of spread. So far, research has focused on forest stands, however, the movemen...

Efficacy of commercial wood preservatives against Bursaphelenchus xylophilus, a quarantine organism in Europe
2014 - IRG/WP 14-30638
Bursaphelenchus xylophilus (Steiner and Buhrer 1934) Nickle, 1970, pine wilt nematode (PWN), is a quarantine organism with a high potential to damage Conifer forests in Europe. This has driven the European Union to protect forest stands from the propagation and dispersion of this pathogen. Since the nematode was detected in Europe, eradication measures were taken. However, these measures were unsu...

The situation of the industrial protection of wood in Argentina (La situación de la protección industrial de la madera en Argentina)
2015 - IRG/WP 15-30675
Argentina holds 33 million hectares of native forests and 1.2 million hectares of cultivated forests, which make it the 3rd Latin American country with the largest surface of cultivated forests of the region. (Ministry of Industry, 2012). The industrial impregnation of wood through vacuum pressure was first implemented in our country in the year 1932, and currently there are over 100 active plants...

Fire protection of wooden facades in Norway
2015 - IRG/WP 15-40710
Wood products are experiencing a renaissance as construction material in Europe due to their environmental benefits. In Norwegian building design however, timber has always played an important role but has had its limitations in urban architecture. One of the reasons is a high demand to fire safety in dense house building and multi-story buildings. Though novel construction methods and fire safety...

Effect of a Water Repellent Treatment on Moisture Behavior of Three Australian Hardwoods: A Preliminary Report
2021 - IRG/WP 21-40921
Wood is inherently hygroscopic and will sorb moisture either directly from the atmosphere or via capillary action. Moisture can have marked effects on wood properties and repeated wetting and drying creates dimensional changes that lead to physical damage. Exposure to elevated moisture levels also increases the risk of fungal attack.
Wood preservatives have long been used to minimize the risk of ...

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...

Australian timber durability research needs
2023 - IRG/WP 23-50385
Australia was once a world leader in timber durability research, but prolonged disinvestment resulted in a gradual decline in capacity. Forest and Wood Products Australia recognized this problem and supported the development of the Centre for Timber Durability and Design Life to help reverse this decline and begin to educate the next generation of Australian researchers. The Centre is a collabor...
