Attractive factors of steam-treated larch wood to termite feeding
1998 - IRG/WP 98-10256
The hot water extractives from steam-treated Japanese larch wood were studied to understand the chemical properties of attractive factors of the treated wood to feeding behavior of a subterranean termite, Coptotermes formosanus. Hot water extractives were fractionated and analyzed using chromatography, gel filtration, and NMR methods.

Termite response to Agricultural Fiber Composites: Bagasse
2005 - IRG/WP 05-10549
Bagasse, or sugarcane rind, is a fibrous by-product of sugar extraction from sugarcane, Saccharum officinarum L. Bagasse fiber performs similarly to hardwood fiber in composite board products. In laboratory studies, Formosan subterranean termites survived as well on a diet of Bagasse as on Douglas-fir wood. Field tests with a compressed Bagasse panel (produced by heat extrusion) indicated that ter...

Evaluating the natural durability of native and tropical wood species against Reticulitermes flavip
2004 - IRG/WP 04-10539
Environmental pressures to eliminate arsenate from wood preservatives has resulted in voluntary removal of CCA for residential applications in the United States. A new generation of copper organic preservatives has been formulated to replace CCA for decking and in-ground applications but there is no guarantee that these preservatives represent a permanent solution to all related problems. There...

A laboratory evaluation of the fumigant, sulfuryl fluoride (VikaneR), against the Formosan termite Coptotermes formosanus Shiraki
1982 - IRG/WP 1164
A series of laboratory experiments showed that the fumigant sulfuryl fluoride (VikaneR) was effective against small groups of Coptotermes formosanus Shiraki exposed to the gas directly at temperatures from 20-40°C. At 10°C fumigations failed regardless of initial gas concentration. Very high or total mortality was observed at concentrations of 0.79 cc/L or higher. A second series of experiments ...

Chemical evaluation of borate treated pine sapwood attacked by the subterranean termite Coptotermes acinaciformis
1993 - IRG/WP 93-20003
Sapwood of hoop (Araucaria cunninghamii Ait. ex D. Don) and slash (Pinus elliottii Englem.) pines were treated by Vacuum Pressure Impregnation (VPI) to provide test specimens. The concentration of boron was defined by chemical analyses of the timber, in the zone of primary attack by the termite being bioassayed. A common method of definition of preservative retention, weight uptake of preservative...

Leaching characteristics, decay and termite resistance of treated wood with boron compounds, N'-N-(1,8-Naphthalyl) hydroxylamine (NHA-Na), and hydroxynaphthalimide (NHA-H)
2003 - IRG/WP 03-30307
Despite many advantages of boron wood preservatives, boron itself does not adequately protect wood in ground contact and exterior applications because its natural diffusibility and susceptibility to leaching. As a result of previous studies to limit or decrease boron leaching, several fixation systems have been developed. In this study, we evaluated the effects of N'-N-(1, 8-Naphthalyl) h...

Comparison of three methods for assessing the in-ground termite resistance of treated timber, durable timber and plastics at sites in Australia, USA and Thailand - First results
1998 - IRG/WP 98-20132
The in-ground resistance of materials to attack by subterranean termites is most commonly assessed with one form or another of the conventional graveyard method, despite the significant shortcomings of this method. In Australia, an alternative method, in which all samples of test materials are placed below-ground, has been in use for more than 10 years. The method provides reliable exposure of sam...

Durability of Bamboos in India against termites and fungi and chemical treatments for its enhancement
2005 - IRG/WP 05-10553
Bamboo is a very important forest resource that benefits the life of people in a myriad ways including meeting the need for structural uses like posts, pole fencing, scaffoldings, house building, etc. Although it is one of the strongest structural material available, often succumbs to fungal decay and biodeterioration by insects (termites and powder post beetles) during storage and usage. Studies...

Japanese standardized methods for testing effectiveness of chemicals against termite attack
1986 - IRG/WP 1290
Japanese standard termiticide testing methods are reviewed. There are some standard testing methods provided by Japan Termite Control Association (JTCA) and Japan Wood Preserving Association (JWPA), though most of them are common to two organizations. Methods were standardized between JTCA and JWPA in 1981, and more recently examining system was established for authorizing efficacy of wood preserv...

Biocidal screening method of wood extractives by a direct use of cellulose TLC plate
2001 - IRG/WP 01-20226
Most of the methods to evaluate the biological durability of woods have focused on decay fungi and termite as deteriorating organisms and it is well known that one of the most important factors affecting the biological characteristics of wood is extractives. Bioassays for evaluating the biological activities of wood extractives have been mainly conducted with treated filter papers for termites or ...

A rapid method for collecting large numbers of subterranean termites from wood
1982 - IRG/WP 1165
A corrugated fiberboard trap is described which attracts large numbers of subterranean termites from infested logs. Single-trap collections in excess of 63 grams (wet wt.) for Reticulitermes virginicus (Banks) and 43 grams for Coptotermes formosanus Shiraki were taken one to three days following discovery by termites. If traps are removed from the source logs shortly after beeing attacked, termite...

Establishing standard principles for laboratory bioassays of termiticides with subterranean termites - progress, problems and prospects
1993 - IRG/WP 93-10013
Laboratory bioassays of termiticides, including wood preservatives, aim to give an indication of the likely concentrations effective in preventing damage to timber products and other materials in the field. In laboratory bioassays field conditions should be simulated as closely as possible. With a wide range of procedures in use around the world it may often be difficult to compare results between...

Options for termite management using the insect pathogenic fungus Metarhizium anisopliae
1996 - IRG/WP 96-10142
The insect pathogenic hyphomycete fungus Metarhizium anisopliae (Metschnikoff) Sorokin is promising as a biological insecticide for many species of subterranean termites. In Australia, a survey of termite mounds and feeding sites using a selective medium showed that this fungus is widespread but rarely causes mortality of termites under natural conditions. One isolate, codenamed FI610, has been se...

Termite Field Tests of Various Timber Species Treated with permethrin using supercritical carbon dioxide
2005 - IRG/WP 05-10560
Termite field tests were conducted on permethrin-treated Eucalyptus obliqua heartwood, Pinus radiata sapwood and P. radiata LVL. The permethrin was impregnated using either supercritical carbon dioxide (scCO2) or light organic solvent preservative (LOSP) systems. Comparative permethrin retentions were most accurately achieved in P. radiata sapwood, where no difference between impregnation systems ...

Variance in feeding on equivalent wood blocks by the Formosan subterranean termite (Coptotermes formosanus Shiraki)
1987 - IRG/WP 1325
We tested whether laboratory groups of Coptotermes formosanus Shiraki forage randomly when they are given 4 equivalent wood blocks, and whether group size affects variance of feeding on equivalent blocks. In all cases, foraging was not random, but, rather, the termites concentrated on a few preferred blocks. Group size did not affect this pattern of non-randomness. These data are useful for design...
