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...

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In August 1987, organochlorines were withdrawn in North America from use in termite control.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

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...

Review of remediation methods of sites contaminated by wood preservatives - testing of filter material for use in permeable barrier technology
1999 - IRG/WP 99-50141
Several treatment methods are currently available for treatment of contaminated sites. Soil and water can be treated by immobilisation, separation or destruction of contaminants. It has been common to use intensive treatment methods starting with soil excavation to reach strict purification goals. However, technical and financial reasons make it difficult to reach the desired treatment criteria. A...

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 ...

Controlled fixation technology
1995 - IRG/WP 95-50040-12
Controlled fixation techniques have been developed and adopted in a number of countries where chromium containing preservatives are predominantly used. The purpose of this technology is to reduce both on-site pollution and holding requirements for freshly treated timber. The fixation mechanism is complex and the time taken to complete the reaction is dependent upon a number of factors. A number of...

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...

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...

Strategies for enhancing usage of treated wood in Indian context
2005 - IRG/WP 05-40305
India constitutes 2% of the world’s forest area but it has to support over 15% of the human and nearly 14% of the cattle population and therefore forests in India are under immense biotic pressure. The main concern today is the rate at which avoidable factors or man made threats accelerate the process of forest degradation and to evolve measures to check the same. Man made threats include expl...

In search of excellence - A necessary challenge
1990 - IRG/WP 3567
Consumerism and environmentalism are gaining much influence. At national and E.C.-level the policy conducted is based on prevention of pollution through "sound" wood preservatives. Supposing that "environmental friendly" products do not exist it is understood that "sound" products have least effect on the environment during their whole life cycle. In the past only the effectiveness was paramount, ...
