Development of a Granitgard® particulate termite barrier for use in tropical Australia
1997 - IRG/WP 97-10190
Granitgard® is superficially simple technology; graded crushed aggregate, sieved to a size range impenetrable to subterranean termites. However, behind this apparent simplicity lies a large research effort. In this paper we describe the laboratory development of a grading of Granitgard suitable for use against the wide range of termites which attack timber in northern Australia, above the Tropic ...

A critical review of the AWPA standard method (M12-72) for laboratory evaluation to determine resistance to subterranean termites
1986 - IRG/WP 1298
The American Wood Preservers' Association standard (M12-72) for evaluation of candidate wood preservatives against subterranean termites is reviewed and suggestions for revision are made. The most serious flaws in the current test procedure involve a failure to recognize inter- and intraspecific variation and a lack of quantification of test results....

Baiting techniques for subterranean termite control
1983 - IRG/WP 1205
The use of artificial baits, with and without toxins, have proved effective in attracting large numbers of non-mound and mound building subterranean termites in both urban and rural areas. An outline is presented of a termite baiting program which emphasises concurrent laboratory and field investigations on termite ecology, behaviour and physiology...

Ultrastructure of the attack of a naturally durable timber by tunnelling bacteria
1990 - IRG/WP 1462
The attack of the wood of Eusideroxylon zwageri, a naturally durable species, by tunnelling bacteria (TB) was examined by light microscopy and transmission electron microscopy. Observations were made primarily on fibres. Parenchyma were included in some cases. Both fibres and parenchyma are rich in extractives. In fibres, extractives are primarily present in the lumen. The amber colouration of fib...

Sequential exposure of borate treated Douglas-fir to multiple Formosan subterranean termite colonies in a 40-week field test
1993 - IRG/WP 93-10006
Douglas-fir boards (ca. 74.5 g) pressure-treated with disodium octaborate tetrahydrate (DOT) retentions of 0 (controls), 0.88, 1.23, 1.60, or 2.10% (weight/weight) DOT were sequentially exposed to four active field colonies of Formosan subterranean termites, Coptotermes formosanus Shiraki (Isoptera: Rhinotermitidae), in an above-ground field test. Samples were placed in contact with each colony fo...

Results on termite resistance of building materials against Coptotermes formosanus by choice test
1998 - IRG/WP 98-10275
Various building materials, included wood species, wooden board materials, thermal insulation materials and fire-protection materials, were tested for grading of termite resistance against Coptotermes formosanus. The dimension of most specimens were 2x2x2cm3. Ten repeats were prepared. The specimens were put between Akamatsu sapwood control specimens on a laboratory cultured mound colony of termit...

Preliminary attempts towards the development of a small-scale termite rearing chamber
1982 - IRG/WP 1148
The paper suggests how to prepare a small-scale rearing chamber for termites which might be used for testing the effectiveness of possible termiticides. A technique for breeding the termites is suggested....

Studies on the foraging of subterranean termites
2000 - IRG/WP 00-10345
To study the foraging galleries of subterranean termites in soil, early researchers painstakingly excavated underground tunneling system of these cryptic insects. Erhorn (1934) listed a report by Oahu Sugar Co., Ltd. in 1928 showing that runway of Coptotermes formosanus may extend up to 50 m long and 0.3 - 3 m deep. Ratcliffe & Greaves (1940) who excavated foraging galleries of Coptotermes lac...

Changed susceptibility of the chemically and thermally degraded spruce wood to its attack by the dry rot fungus Serpula lacrymans
1999 - IRG/WP 99-10322
In buildings, some intentional or unintended situations can occur at which some wood products are exposed to aggressive chemicals and also to higher temperatures. Occasional activity of fungi on such pre-attacked wood products can be either higher or lower. This paper deals with changes in the susceptibility of spruce wood (Picea abies L. Karst.) to attack by the dry rot fungus Serpula lacrymans, ...

Termite standards questionnaire survey - First Report
1988 - IRG/WP 1354
Information contained in replies received from IRG members responding to the termite standards questionnaire survey are summarised. Highlighted in the results of this first report are the major termite species in the various zoogeographical regions, their damage ranking to timber-in-service, the chemicals used in control methods, and the status of termite standards in the respondent countries....

Wood preservation in the Australian beekeeping industry
1988 - IRG/WP 3473
This paper reports the results of a survey of Australian commercial beekeepers working 200 or more hives in June/July 1985. Nine hundred and forty seven apiarists were asked to participate and to provide information on their wood preservation methods, painting procedures and maintenance of bee boxes. Three hundred and eighty-four apiarists returned completed questionnaires (41%). The main wood pre...

Techniques for field assessment of particulate termite barriers
2000 - IRG/WP 00-10376
Field testing of particulate termite barriers poses problems different from those encountered when testing preservatives or soil termiticides. To ensure an adequate level of challenge, and minimise the risk of a Type II error, the experimental design must promote termite activity and provide a significant, readily detectable, food source which can only be reached by penetrating the test barrier. I...

Oxygen index levels and thermal analysis of wood treated with melamine-formaldehyde-boron combinations
1997 - IRG/WP 97-30135
Melamine formaldehyde (MF) resin was impregnated into scots pine (Pinus sylvestris L.) specimens with aqueous solutions of 5, 10 and 20% concs. Boric acid (BA) and borax (BX) was added to MF resin at the concentration levels of 0.25, 1.00 and 4.70% to each level of resin concs. BA and BX mixture was prepared at the 5:1 (w/w) ratio considering resultant pH of solutions and better fire resistance. U...

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...

Preventing fungal attack of freshly sawn lumber using cinnamon extracts
2007 - IRG/WP 07-30432
The potential for using cinnamon oil as an anti-mold and stain compound was investigated on ponderosa pine sapwood. Cinnamon oil was highly effective when used in ethanol, but its activity declined when it was mixed with only water. Attempts to enhance water solubility with surfactants improved solution stability, but had no apparent effect on biological activity. Further studies with other co-so...

Performance if internal remedial treatments to arrest fungal attack in poles and large timbers
2018 - IRG/WP 18-40834
Internal remedial treatments have been used to arrest internal fungal attack in utility poles and other large timbers. Water diffusible systems and volatile fumigants have both been used for this purpose. While both work, it is important to understand the performance attributes of each system. This paper reviews the literature on both systems and makes recommendations for future research....
