Enhanced biodegradation of cocopeat by soft rot fungi
1998 - IRG/WP 98-10276
Biodegradation of cocopeat (coir dust) was enhanced by the addition of nitrogen (N) fertilizer and inoculation with the soft rot fungus Chaetomium globosum. The N and fungally treated cocopeats had a greater percentage weight loss (27%) after 3 months compared with 7% weight loss without the added fungi and N fertilizer. In addition, their hemicellulose, cellulose and lignin contents were greatly ...

Controlling Coptotermes (Isoptera: Rhinotermitidae) infestations in buildings with bait boxes
2000 - IRG/WP 00-10372
This paper describes the results of a commercial pest control operators use of the CSIRO bait box procedure in controlling infestations within buildings of subterranean termites ('termites') of the genus Coptotermes. Polystyrene bait boxes (480 x 330 x 210 mm3) were filled with alternate layers of corrugated cardboard and kiln-dried hardwood strips of Eucalyptus regnans F. Meull....

SEM of wood dust particles
1997 - IRG/WP 97-50084
Dust particles from beech and oak trees have been classified in Germany as being "working materials which are definitely carcinogenic to humans". All other wood dusts, including those from softwoods, are classified as being materials "with reasonable suspicion of carcinogenic potential". The carcinogenic principle of action continues to remain unclear. The mechanical irritation is one of a number ...

Inorganic preservatives in wood dust - Cause of nasal cancer?
1997 - IRG/WP 97-50085
Since 1985 dust particles from beech and oak trees have been classified by the Senate Commission of the German Research Council (DFG) as being ,,working materials which are definitely carcinogenic to humans". All other wood dusts, including those from softwoods, are classified as being materials ,,with reasonable suspicion of carcinogenic potential". The carcinogenic principle of action continues ...

Bait box technique for remedial subterranean termite contro
1995 - IRG/WP 95-10115
The bait box technique, as described in this paper, was first used as a method to apply the dust toxicant, arsenic trioxide, to large numbers of aggregated subterranean termites. Over the last twelve years or so the technique has been refined, and in recent years, gained acceptance as an alternative subterranean termite control measure by members of the Australian pest control industry. This baiti...

Intrigue Dust - A new method of eradicating subterranean termite (Isoptera: Rhinotermitidae) colonies
2001 - IRG/WP 01-10396
Arsenic trioxide is used by pest controllers in Australia to eradicate subterranean termite colonies. In 2000 Bayer Australia introduced Intrigue Termite Dust as a more environmentally acceptable alternative. Intrigue, containing 80% triflumuron, a chitin synthesis inhibitor, disrupts the moulting process in termites. Dusted termites return to the nest and pass around triflumuron via mutual groomi...

Silafluofen: Novel chemistry and versatility for termite control
1995 - IRG/WP 95-30069
A novel silicon - containing insectizide, HOE 084498 ('Silafluofen'), with a favourable toxicological profile, has shown activity against a broad spectrum of agricultural and environmental health pests. Results from laboratory and field studies around the world have demonstrated that silafluofen is effective at protecting timber from attack by various species of termite and wood-...

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...

Efficacy of Avermectin B1 dust and bait formulations in new simulated and accelerated field tests
1985 - IRG/WP 1257
Avermectin B1 on a silica carrier dust was used in dust and bait formulations whose efficacy against Reticulitermes flavipes was assessed in new simulated and accelerated field tests. A 0.5 mg avermectin/mg dust and a bait with 50 ppm avermectin in paper pulp sandwiched between pieces of corrugated boxboard caused nearly complete mortality in bioassays and suppression of foraging in field tests. T...

Evaluation of literature on adenocarcinomas in wood workers
1997 - IRG/WP 97-50092
Occupational exposure to wood dust alone or chemically treated is suspected to be associated with an increased risk of developing adenocarcinoma of the nasal cavity, which in the general population is very rare; fewer than 10% of nasal cancer deaths are adenocarcinomas, which have an annual incidence of 1-2 per million. However, the epidemiological data available are not sufficient to make a defin...

Efficacy of triflumuron dust against Schedorhinotermes intermedius (Isoptera: Rhinotermitidae)
2000 - IRG/WP 00-30226
Insecticidal dusts have been used against termites for decades, with arsenic dust being the standard in Australia. While fair success over the years has been achieved against genera such as Coptotermes and Nasutitermes, Schedorhinotermes has been much more difficult to control. This genus has nests which are very difficult to locate and thus it is problematic to determine whether a treatment has b...

Transfer of Termiticidal Dust Compounds and their Effects on Symbiotic Protozoa of Reticulitermes flavipes (Kollar)
2008 - IRG/WP 08-10661
Dusting of termites in situ has been used as a control measure for decades; however environmental awareness of the toxicity of certain compounds now limits their use (eg arsenical dusts). Our laboratory is in the process of suppressing an isolated colony of Reticulitermes flavipes (Kollar) from a small village of 250 homes in mid-central Wisconsin (Endeavor, WI). Initial treatment of the colony in...

The utilization of sand dusts of MDF panel as filler in wood plastic composites
2010 - IRG/WP 10-40500
Waste management is getting important in the world. Most of wood based panel industries are interested in utilization of wood residues such as saw dust, sand dust and wood flour in other applications. The objective of this study is to investigate the usability of sand dust of MDF in wood plastic composites. HDPE and PP based composites with 30 % sand dusts loading were compounded in the single sc...
