A risk model for termite attack in Australia
2003 - IRG/WP 03-10468
This paper describes a model to predict the risk of termite attack on a house in Australia. It is based on a survey of expert opinion and data from 5000 houses. The model gives a quantitative estimate of risk, and as such is useful for the development of risk management systems. An example of the application of such a system is given....

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...

Experimental real building evaluation of termite attack - Effect of the space between the mat foundation and the thermal insulation
2000 - IRG/WP 00-10374
For evaluating the termite resistance of the real house foundation, specially in the case of thermal insulation systems for foundation walls, thermal insulation which can be attacked by termite, must be evaluate. Because of the difficulty of the water penetration of thermal insulation, the water barrier systems can be protected against termite attacks, in our opinions. The observation on the proce...

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...

Biocides - Efficacy assessment and doses for wood preservatives (product type 8). Local/geographical aspects. Termite control as case study
1999 - IRG/WP 99-20181
Currently, the efficacy of a wood preservative, as biocidal product type 8, is assessed as a ‚critical value' (CV), an efficient dose (retention in wood at a given depth of penetration). CVs are planned to be adapted for exposure to basic target organisms (5 hazard classes) and additional requirements concerning the occurrence of local target organisms in relation with climate, building...

Implications for comparability of laboratory experiments revealed in studies on the variability in survival and wood consumption between colonies of Coptotermes acinaciformis (Froggatt) (Isoptera: Rhinotermitidae
1983 - IRG/WP 1196
(Summary of paper 1193)
Groups of Coptotermes acinaciformis, originating from six colonies, three taken from each of two localities, 1500 km apart, in northern Australia (Townsville, Darwin) were kept at population densities of 0.005, 0.01 and 0.02 g termites/mL. Survival and wood consumption of the groups after 8 weeks followed a similar pattern in the colonies from both collection areas. Groups were least vigorous at the lowest population density; their performance reached a maximum at a population density of 0.01 g/mL. The subsequent decline in vigour was less marked as the highest population density was approached. However, the actual values for survival and wood consumption varied widely between colonies, irrespective of their origin. It is recommended that in all laboratory experiments which use survival and wood consumption as indicators of termite vigour, controls of a favourable as well as an unfavourable food type are included which would serve to monitor the vigour of the termites. Results from termite sources whose vigour falls below a certain threshold value would have to be treated with caution and could not be used in definative data, as e.g. in defining critical retentions of wood preservatives.

Evaluation by experimentation on site of a new method for termite control
1996 - IRG/WP 96-10173
A new concept of subterranean termite control consists of the installation of toxic baits in or around the infested construction. Dow Elanco has developed a bait system based on Hexaflumuron. This active ingredient is an insect growth regulator with slow acting effect. A lot of trials were conducted in the USA, but none in France until now. We realised on site experiments, in order to estimate the...

Termite barriers for new construction
2000 - IRG/WP 00-10341
Subterranean termite protection in Australia has traditionally relied upon the creation of a zone of poisoned soil under and around the structure to prevent termite attack from the ground. The transition away from persistent soil poisons which began with the withdrawal of cyclodienes in 1995 provided market opportunities for innovative barrier systems. The new barrier systems currently being used ...

Tunneling ability of subterranean termites through termiticide-treated soil
1988 - IRG/WP 1375
A test apparatus was designed to facilitate accurate measurement of termite penetration into termiticide-treated soil; three termiticides at 500 ppm were evaluated. Coptotermes formosanus Shiraki workers tunneled significantly farther into chlordane-treated soil than did Reticulitermes flavipes (Kollar). Both species only slightly penetrated chlorpyrifos-treated soil. Neither species penetrated so...

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...
