Termites in Uruguay; control, prevention and environment
1991 - IRG/WP 1474
When Prof. La Fage's questionaire on termites was received by 1987, few were aware of termite damage in Uruguay and infestations were not much reported. Further contacts between scientists, operators and homeowners, are now shaping the real threat of termite attack. Before letting the problem faIl in the hands of the layman, with all ist environmental risks, it seemed reasonable to: 1) re...

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...

A Long-term Observation of Termite Activity in The Nest by Continuous Acoustic Emission (AE) Monitoring
2003 - IRG/WP 03-20280
In order to evaluate the influence of temperature on the termite activity, acoustic emission (AE) monitoring was applied to two nests of Coptotermes formosanus SHIRAKI; a nest in the stem of a standing tree and a nest in the underground of a wooden house, respectively. Temperature change in and around the nests were continuously measured for about one year using thermocouples at four points; the c...

Leaching of arsenic, copper and chrome from preservative-treated timber in playground equipment
1984 - IRG/WP 3149
Samples were taken from CCA-treated timber in sand play boxes and other play ground equipment. Sand was also sampled. Sand and wood samples were analysed for copper, chrome and arsenic by AAS. About 20-25% of the arsenic had leached from the timber after 2-4 year's exposure in the playgrounds. Very little of the copper and chrome had been leached. Sand collected in the close vicinity of t...

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,...

Building with termites: The challenge of biomimetic design for carbon neutral buildings.
2009 - IRG/WP 09-20405
The main aim of this paper is to present humanity and termites as design partners in the creation of a new dimension of ecosystem understanding. “Beyond biomimicry: What termites can tell us about realizing the living building”, Turner and Soar (2008) opens up a new era in how we think of human habitations, not only on earth, but maybe on other planets, and using the termite model as the corne...
