International comparison of three field methods for assessing the in-ground termite resistance of materials - highlights after two years
1999 - IRG/WP 99-20157
First-year results of a comparative study, evaluating the in-ground termite resistance of a range of materials, including CCA and ACQ-treated timbers, using the below-ground exposure, ground contact and graveyard methods against diverse termite faunas were provided in IRG/WP/98-20132. Further annual inspections have confirmed early trends and identified notable differences between sites and method...

Comparison of three methods for assessing the in-ground termite resistance of treated timber, durable timber and plastics at sites in Australia, USA and Thailand - First results
1998 - IRG/WP 98-20132
The in-ground resistance of materials to attack by subterranean termites is most commonly assessed with one form or another of the conventional graveyard method, despite the significant shortcomings of this method. In Australia, an alternative method, in which all samples of test materials are placed below-ground, has been in use for more than 10 years. The method provides reliable exposure of sam...

Laboratory evaluation of six commercial termiticides against subterranean termite, Coptotermes gestroi Wasmann
1994 - IRG/WP 94-30034
Small specimens of Heavea brasiliensis (10 x 10 x 20 mm³) were exposed to the laboratory colony of Coptotermes gestroi Wasmann for 4 months after dip- or brush-treatment with six commercially available emulsifiable termiticides (alpha-cypermethrin, cypermethrin, permethrin, bifenthrin, chlorpyrifos and chlordane). Synthetic pyrethroids and chlorpyrifos were effective as well as 1% treatment of ch...

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...

International comparison of three field methods for assessing the in-ground resistance of preservative-treated and untreated wood to termites and fungal decay – Summary of observations after five years
2003 - IRG/WP 03-20261
Results are presented from a five-year study conducted in five locations in Australia, Thailand and the USA. Three methods of exposure were assessed (below-ground, graveyard and ground contact) for evaluating the in-ground termite and decay resistance of Pinus radiata D. Don sapwood stakes that had been vacuum pressure impregnated with CCA (Type C) and ACQ (Type D) each at two nominal retentions (...

Foraging patterns of termite species in the living complexes of Bangkanoon forest plantation, Phuket province, Southern Thailand
2003 - IRG/WP 03-10481
Studies on foraging patterns of termite species in the living complexes of Bankanoon Forest Plantation, Phuket Province, southern Thailand, gave result of 11 species of subterranean termites (Coptotermes gestroi, Microtermes obesi, Macrotermes gilvus, Macrotermes carbonarius, Macrotermes anandalei, Odontotermes feae, Odontotermes proformosanus, Hypotermes makhamensis, Globitermes sulphureus, Micro...

Long-time efficacy of some soil termiticides tested according to “Modified Ground Board Test”
2018 - IRG/WP 18-10935
Field trials of efficacy of soil termiticides available in Thailand were started back in the 1980s at four different locations representing different unique weather types of the country. The method used in the trials (Modified Ground Board Test) is the compulsory test for every soil termiticides aiming to be registered for termite control in Thailand. The ongoing record reveals that some particula...
