A method to evaluate the effeetiveness of bait application using a transferred nest of Coptotermes formosanus Shiraki (Isoptera: Rhinotermitidae)
1999 - IRG/WP 99-20161
Although a survey of monitoring stations can tell us the decline of termite activity after application of baits, it seems questionable to conclude an eradication of a Whole colony of subterranean termites if the termites move out their foraging territory. Only reliable method to ensure the success of bait application is to determine the absence of living termites in their nest in accordance with a...

Efficacy of hexaflumuron as a bait-toxicant in the field using a transferred nest of Coptotermes formosanus Shiraki (Isoptera: Rhinotermitidae)
2000 - IRG/WP 00-10379
A natural nest of Coptotermes formosanus Shiraki was transferred into the field test site, and monitoring stations were installed around the nest buried back in the ground in January, 1995. Following estimation of foraging populations [271,200o}49,600 (July - October, 1996); 142,600o}19,600 (April - July, 1998)], bait applications were conducted twice. Termites came back to the stations in spring,...

Physical barriers and bait toxicants: The Romeo and Juliet of future termite control
1991 - IRG/WP 1503
Soil chemical barriers are considered by some to be the most important technique for protecting buildings against subterranean termites in Australia (and elsewhere), providing a barrier against termite penetration. However, there is no such thing as a barrier that is 100 per cent +protective. And given the worldwide problems of using organochlorine termiticides, public awareness of chemical pollut...

Trials on the field control of the Formosan subterranean termite with Amdro® bait
1982 - IRG/WP 1163
Amdro® - treated paper towels were introduced into two field colonies of the Formosan subterranean termite in Hawaii. At the concentration of 180 ppm, the toxicant bait was ineffective one month after the introduction. At higher concentrations (> 6,400 ppm), the baits were eaten initially; however, one week after introduction, termites avoided or covered the baits. The 15,000 ppm baits supress...

A method for screening termite baits using Coptotermes lacteus mounds
1984 - IRG/WP 1237
A method with several variations designed to rapidly screen potential bait substrates using Coptotermes lacteus mounds is described. The equipment used in this method is relatively inexpensive, readily prepared in the laboratory, and easily installed into active mounds in the field. Bait substrates are in continuous contact with a 'high termite hazard', and may be monitored with ...

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....

Improved resistance of Scots pine and Spruce by application of an oil-heat treatment
2000 - IRG/WP 00-40162
Spruce (Picea abies L. Karst.) and Scots pine (Pinus sylvestris L.) were subject to a heat treatment which was carried out in an oil-bath. The aim was to improve the dimensional stability of the treated wood and its resistance against fungi. The bath of vegetable oil provides a uniform heat transfer at temperatures of 180°C, 200°C and 220°C and protects the submersed wood from oxygen. Heat trea...

Timber Preservation and Sustainable Construction in Australia
2005 - IRG/WP 05-50224-14
Sustainable development has been described as meeting the needs of the present without compromising the ability of future generations to meeting their own needs. (Bruntland 1987) To achieve the sustainable development goal therefore, the maximum performance has to be obtained from existing resources (timber) so that the remaining resource is protected from over-exploitation. Clearly, wood preserva...
Justification for use of mirex in termite control
1988 - IRG/WP 1346
In August 1987, organochlorines were withdrawn in North America from use in termite control. This has left the industry and the community with reduced options in long term protection of wood and wood products. A case is presented to justify the use of the slow-acting stomach termiticide, mirex, under special permit, for use only in the bait-block method of termite control. This method, while not a...

Effects of methoprene on Coptotermes formosanus (Isoptera: Rhinotermitidae)
1987 - IRG/WP 1322
Methoprene affected differentiation and survival of Coptotermes formosanus Shiraki in laboratory studies. At 5, 9, 13, and 17 weeks, superfluous intercastes and presoldiers were produced when termites were allowed to feed on concentrations of 1,000 and 2,000 ppm methoprene in wood blocks. Colony numbers were significantly reduced after 13 and 17 weeks of exposure to the insect growth regulator. Te...

Preference of the Formosan subterranean termite for wood previously damaged by conspecifics
1988 - IRG/WP 1338
In a laboratory choice test, groups of termites from five colonies of Coptotermes formosanus Shiraki were presented with wood blocks which had sustained previous termite damage: 1) by nestmates, 2) by conspecifics from another colony, 3) by another termite species, Reticulitermes virginicus Banks, and 4) no damage. Coptotermes formosanus preferred wood previously damaged by conspecifics over that ...

Safe application of copper-chrome-arsenate preservatives
1975 - IRG/WP 377
All wood preservatives contain biologically active substances and must, by design, be in some measure toxic to man. There is nothing fundamentally difficult, however, about using a wood preservative with complete safety. It depends on knowing the risks to health and/or the environment, which the preservative may present, and planning application accordingly. In this paper we examine these and othe...
