Insect growth regulators: modes of action and mode of action-dependent peculiarities in the evaluation of the efficacy for their use in wood preservation
1997 - IRG/WP 97-30155
Up to now, the insecticides used in wood preservation are either of more or less non-specific mode of action - like boron - or of neurotoxic mode of action - like chlorinated hydrocarbons, carbamates and pyrethroids. The active ingredients actually used are primarily mirroring the progress in active ingredient research in plant protection. The methods of testing of the insecticidal efficacy of woo...

Effects of a chitin synthesis inhibitor on spore germination of the decay fungi Gloeophyllum trabeum and Poria tenuis
1986 - IRG/WP 2253
This study sought to determine the effect of a chitin synthesis inhibitor - Polyoxin D, on spore germination and early hyphal development of a brown rot and a white rot fungus in-vitro. Polyoxin D is a competitive, substrate-analogue type of chitin synthtase inhibitor (2). The drawbacks to use of such a compound as a wood preservative tie. cost - $20,000/g, possible leaching or degradation) might ...

Evaluating the Exterra Termite Interception and Baiting System in Australia
2003 - IRG/WP 03-20267
The Exterraä Termite Interception and Baiting System (Ensystex Inc., Fayetteville, NC) was evaluated in a field experiment near Townsville, Australia. Cellulose-acetate powder containing either 0.05% weight/weight (w/w) or 0.25% w/w chlorfluazuron (Requiemä) was tested for its efficacy in eradicating colonies of the mound-building subterranean termite Coptotermes acinaciformis (Froggatt). Thirte...

How predictive are laboratory experiments for assessing the effects of chitin synthesis inhibitors (CSI) on field colonies of terrnites? - A comparison of laboratory and field data from Australian mound-building species of termit
1996 - IRG/WP 96-10143
A singular advantage of using mound building species of termite is their directly accessible nest. This allows evaluation of control methods by accurate assessment of the effects at the colony level. The mound building species Coptotermes acinaciformis (Froggatt) and Nasutitermes exitiosus (Hill) were used to test the CSI, hexaflumuron, in laboratory and field trials. Laboratory results showed tha...

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...

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...

Laboratory evaluation comparing three commercial termite baits based on chitin synthesis inhibitor (CSIs) against the subterranean termites Coptotermes acinaciformis (Froggatt) and Mastotermes darwiniensis Froggatt
2007 - IRG/WP 07-10625
This laboratory bioassay report describes laboratory evaluation undertaken to compare the efficacy, and palatability of Requiem®, Nemesis® and Sentricon® AG as candidate bait toxicants against the subterranean termites Coptotermes acinaciformis (Froggatt) and Mastotermes darwiniensis Froggatt. The laboratory bioassay results confirmed palatability and efficacy differences between the three comm...

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...

Wood preservative obtained by recycling – preliminary selection of leaching inhibitor
2008 - IRG/WP 08-50252
Based on recycling of used household batteries, a process was developed to enable the recovery of major manufacturing components, leading to a solution of zinc (32 g.l-1) and manganese (15 g.l-1) salts, free of heavy metals. The potential use of the above solution as wood preservative was demonstrated by means of assays both of fungicidal activity -using white and brown rot fungi- and of insectici...

Using an accelerated laboratory method to evaluate Aureobasidium pullulans colonization on painted surfaces and underlying wood substrate
2012 - IRG/WP 12-20480
Mold growth on painted surfaces can lead to premature paint film failure and is unsightly. Aureobasidium pullulans has been identified as a major cause of black stain on surfaces painted with acrylic or latex paints. In this study, an accelerated laboratory method developed by Zabel and Horner (1981) was used with modifications to the type of agar used and sample evaluation methods. A study was ...

Mold Control for Treated Lumber in Block-Stack Storage Conditions
2012 - IRG/WP 12-30588
The mold development and control for freshly treated and block-stacked wood have been evaluated using a green house mold testing method. The results for the mold resistance of several commonly used water boron preservative treatment systems, such as ACQ, Copper Azole, and borates with and without inclusion of mold inhibitors are presented. The data suggest that the different preservative treatme...

Control of Asian subterranean termites Coptotermes gestroi (Blattodae: Rhinotermitidae) by a new generation bait system with vegetal extracts-diflubenzuron mixture
2023 - IRG/WP 23-30797
The efficacy of anti-termite bait pebble dosed at 0.3% w/w of Diflubenzuron, and Chitin Synthesis Inhibitor (CSI) and 0.6% w/w of vegetal extract from Berkem Biosolutions®, was evaluated in the laboratory on the Asian subterranean termite Coptotermes gestroi (Wasmann). Four concentrations 33.3%, 50%, 50% bis and 100% as well as two neutral matrices, were used in two in-house developed test method...
