Practical applications of steamed larch wood to a termite bait system using chlorfluazuron
2003 - IRG/WP 03-10464
Less chemical strategies are required for decrease of damages to residents from chemicals such as organic phosphates and carbamates those are usually used to prevent termite attacks on wooden buildings. One of the strategies is a bait system that has already been employed in the termite-infested areas. We tried to use steamed larch wood as a monitor wood and a bait matrix to stimulate feeding acti...

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...

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...

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In August 1987, organochlorines were withdrawn in North America from use in termite control.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...

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...

Detection of Acoustic Emission (AE) generated by termite attack in a wooden house
1999 - IRG/WP 99-20166
Recently, considerable attention has been paid to methods for termite control, which involves few or no chemicals. To reduce the amount of termiticide needed, it is necessary to detect termite attack in wood as early as possible. The feasibility of acoustic emission (AE) monitoring for the nondestructive detection of termite attack has been discussed previously. In this study, we propose some tech...

Bait box technique for remedial subterranean termite contro
1995 - IRG/WP 95-10115
The bait box technique, as described in this paper, was first used as a method to apply the dust toxicant, arsenic trioxide, to large numbers of aggregated subterranean termites. Over the last twelve years or so the technique has been refined, and in recent years, gained acceptance as an alternative subterranean termite control measure by members of the Australian pest control industry. This baiti...

Field tests of molybdenum and tungsten baits for termite control
2004 - IRG/WP 04-30345
Molybdenum and tungsten compounds are slow acting to termites and show a high termiticidal efficacy. In our previous papers, we have already reported that those are useful as termiticidal ingredients of bait formulations.
The demand for natural rubber is still on the increase. However some kinds of termites inhabiting rubber plantations damage rubber trees and pose a serious threat.
To cope with...
