Metal Migration from Douglas-fir Poles Treated with Ammoniacal Copper Zinc Arsenate According to Best Management Practices
2010 - IRG/WP 10-50272
The potential for migration of metal components from ammoniacal copper zinc arsenate treated (ACZA) poles was examined using pole sections treated using Best Management Practices. Copper and zinc levels were highest in runoff collected following the first rainfall events, then declined. Copper and zinc levels in runoff averaged 20 ppm and 5 pm respectively. The metal levels were then used to pr...

Phytosanitary standards and the potential for acceptance of chemical treatments as a phytosanitary measure
2011 - IRG/WP 11-30558
Regulations governing international trade in forest products must balance the economic and social benefits of trade with the potential risks of transporting invasive species. The International Plant Protection Convention (IPPC) is an international agreement intended to manage this process. It develops international phytosanitary standards (ISPMs) that are recognised by the World Trade Organisation...

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,...

Termite Management and the U.S. Experience: A Case for Wood Treatment & Integrated Control
2015 - IRG/WP 15-30678
A brief overview of termite control is given using specific experiences from the U.S.A. Five major types of termite treatment now prevail: soil applied chemical barriers, in-structure chemical barriers (in-situ applied wood and foundation treatments), physical barriers, treated wood and termite baits. In general, ‘stand-alone’ pretreatments or ‘primary’ treatments are often discussed and ...

Cryptotermes brevis - a silent earthquake for the wood structures in a World Heritage city in the Azores Islands
2016 - IRG/WP 16-50316
In the Azores archipelago the exotic drywood termite Cryptotermes brevis, detected in early 2000’s, is destroying the wood structures of the typical buildings and is already considered the main urban pest in these islands. This work aims to show the spread evolution of this pest along the last six years in the first Portuguese city classified as world heritage by UNESCO, Angra do Heroísmo. For ...

Environmentally Sustainable Method of Termite Management using a baiting system: A case study in the Philippines
2016 - IRG/WP 16-50317
Environment and sustainability are key words for achieving product and business success. Use of chemicals in human vicinity such as homes and buildings are on the increase, thanks to a growing consciousness on pests. Using chemical insecticide is the main stay to counter these pests, but its role in environment is being scrutinized.Insect baiting technology has proven its success around the world ...

For the understanding of biological strategies to sustainable pest management: the case of Nasutitermes corniger
2018 - IRG/WP 18-10907
Termites have long been a serious pest of wooden constructions, timber products and are still causing an important problem in most of tropical regions. The genus Nasutitermes is among the most abundant wood-feeding Termitidae in South of America. The first aim of this review was to gain new insights into the management of N. corniger, considered to be the most economically detrimental pest of this...

Termite species associated with processed wood in South America
2018 - IRG/WP 18-10934
Termites as an eusocial insect group play an important role in the decomposition of organic matter of cellulose origin and in the modification and quality of soils. Some species are xylophagous, and therefore are considered an important urban pest due to their ability to attack not only wooden building structures but also synthetic materials such as PVC, polyethylene or polyurethane, causing great...

Visual assessment of longitudinal wheel timbers and assessing the feasibility of extending wheel timber service life in the UK railway network
2019 - IRG/WP 19-20651
Timber has been a versatile building material for centuries and during the start of the Railway Age in the nineteenth century it was in considerable demand for use in the railway network, particularly bridge building. Timber is still in service and widely used throughout the UK railway network. The resilience and favourable strength to weight ratio and its relative ease of fabrication make it an...

Effect of damage to polyurea coatings on metal losses from ammoniacal copper zinc arsenate treated Douglas-fir pile sections
2019 - IRG/WP 19-40867
Metal-based preservatives remain the most widely used treatments for protecting wood in soil or water contact. While these treatments are highly effective, one drawback is a tendency for small amounts of metal to migrate into the surrounding environment. The greatest risk in this regard is copper because many organisms are highly sensitive to this metal. While post treatment practices can reduce ...

The influence of climate changes on Central European forests with an emphasis on Slovenia
2022 - IRG/WP 22-50368
When forests are managed sustainably, they play an essential role in protecting climate and biodiversity. They protect soils and water resources, provide livelihoods, and contribute to the well-being of rural and urban communities. European forests are multifunctional and provide a range of ecosystem services. These include the production of renewable materials that can replace materials with a la...

Management of invasive West Indian drywood termite in Queensland: Transition from mandatory to voluntary treatment
2023 - IRG/WP 23-11002
Cryptotermes brevis, the West Indian drywood termite (WIDT) is the most destructive drywood termite globally. It is capable of infesting both softwoods and hardwoods in timber structures. In Australia C. brevis was first discovered in 1940s and later an established infestation was discovered in Maryborough, Queensland in 1966 and then in Brisbane and Bundaberg in 1975. In 1977 the Queensland Gover...

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...
