Laboratory evaluation of AC 217,300 as a termiticidal dust
1983 - IRG/WP 3247
Laboratory bioassays are described with the amidinohydrazone, AC217,300, a candidate termiticide to replace arsenic trioxide in termite control. When used as a dust and topically applied, AC217,300 was toxic to Coptotermes acinaciformis and Mastotermes darwiniensis. Although arsenic trioxide dust causes faster mortality in Coptotermes acinaciformis than AC217,300 dust, the latter has lower mammali...

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...

Effects of two insect growth regulators (IRGs) on Microcerotermes diversus (Silvestri) (Isoptera: Termitidae) in Southwest Iran
2006 - IRGWP 06-10601
Microcerotermes diversus (Silvestri) is the most economically damaging termite species in structures in southwest, Iran. One safe control strategy that may reduce the subterranean termite damage in buildings is the use of IGRs in a suitable bait matrix. The effects of two juvenile hormone analogues, Admiral (Pyriproxyfen ) and Farox on M. diversus were evaluated over a range of concentrations ( 10...

Beetle-Fungus Associations in Woody Substrates in the Context of International Trade
2007 - IRG/WP 07-10610
Interest in the role of insects in transmitting various fungi and in the potential for outbreaks of insects vectoring plant disease organisms has resulted in a large volume of literature on insect-fungi relationships. Mites are mentioned as an important third partner in these associations. This paper summarizes information and provides an update on major aspects of these intricate associations in ...

Quantitative and qualitative losses in wood of oriental spruce, Picea orientalis (L.) Link., induced by insects from forest to utility
2008 - IRG/WP 08-10647
In this study, some quantitative and qualitative losses in wood of oriental spruce, Picea orientalis (L.) Link., induced by insects from forest to utility were evaluated. In experimental plots, volume of trees damaged by Dendroctonus micans (Kug.) was 34% of the volume of total standing spruce trees in the oriental spruce forests of Turkey. The volume of standing trees that D. micans damaged was ...

Laboratory Evaluation of Flurox, a Chitin Synthesis Inhibitor, as a Bait Toxicant Against Microcerotermes diversus (Silvestri ) (Isoptera: Termitidae)
2008 - IRG/WP 08-30477
Microcerotermes diversus (Silvestri) is the most economically destructive termite in structures in southwest, Iran . One sustainable control strategy that usually help in reducing the subterranean termite damage in buildings , which is safe to the user and the environment is the use of IGRs in a suitable bait matrix. In the laboratory assays described here, the delayed toxicity of Flurox (a Chitin...

Termite and insect resistance of acetylated wood
2015 - IRG/WP 15-40703
The benefits from acetylation of wood to enhance resistance against fungal decay and dimensional stability have been known for many years. Since 2007 Accsys Technologies has been commercially producing Accoya® wood that is based on acetylation of radiata pine. A number of studies on the resistance of acetylated wood to attack by wood destroying termites have been conducted, but there is no common...

Effects of Bio-oil Obtained from Laurel (Laurus nobilis) Residues on Biological, Physical, and Mechanical Properties of Treated Wood
2016 - IRG/WP 16-30692
In this study, the effects of bio-oil obtained from Laurel (Laurus nobilis) residues on biological (decay, insect, termite resistance), physical (water absorption, tangential and radial swelling), and mechanical properties (MOE, MOR and CSPG) of treated wood samples were studied. The bio-oil used in this paper was produced by the help of fixed bed reactor type pyrolyzer. GC/MS analysis showed that...

UV-curable coatings developed for aesthetic and biological protection of wood outdoors
2017 - IRG/WP 17-40821
To avoid wood greying, dimensional variations, and degradation by biological agents wood is protected with preservation products and coatings when used outdoors. For some wood species used for cladding, a treatment with a preservation product is required, and is frequently additionally protected with a coating. In this study, Mäder Group developed a new UV-curable coating for outdoors application...

Conversion by insects – alternative method for wood waste up-cycling
2018 - IRG/WP 18-50337
Building industry is a major consumer of materials and waste generator in Europe. The bio-based building materials are considered as interesting alternative in modern building sector due to their low environmental impact. However, in order to increase confidence for bio-based materials application, they should present satisfying performance during service life allowing at the same time their casca...

Self-regulating heating cables for conductive heat transfer in pest control
2020 - IRG/WP 20-40895
Pest control by means of conductive heating of wooden elements requires considerable measuring and control efforts in order to avoid overheating of wooden surfaces, damage of structural elements and risk of fire. The usage of self-regulating heating cables might overcome such problems. In laboratory tests and under real conditions the applicability of self-regulating heating cables is tested with ...
