Compatibility of deltamethrin with wood adhesives
1993 - IRG/WP 93-30031
This work presents the studies conducted on the compatibility of deltamethrin when mixed with wood adhesive to manufacture plywood in order to protect the wood against wood-borers insects and termites. The following types of adhesive were tested: PVA, Urea-formaldehyde, phenol-formaldehyde and a formulation based on tannin. The experiments were made in the adhesive manufacturers' laborato...

Comparative response of Reticulitermes flavipes and Coptotermes formosanus to borate soil treatments
1991 - IRG/WP 1486
Eastern (Reticulitermes flavipes [Kollarl]) and Formosan (Coptotermes formosanus Shiraki) subterranean termite workers (Isoptera: Rhinotermitidae) were exposed to borate-treated sand in an indirect exposure tunneling assay in the laboratory. In the ten day assay period, both termite species readily penetrated sand containing 5000, 10000, or 15000 ppm (wt. of compound / wt. of sand) disodium octabo...

A rapid field bioassay technique with subterranean termites
1983 - IRG/WP 1188
Details are summarised of a field procedure which is designed to ensure continuous exposure to a replenishing termite biomass. After pre-baiting to determine the presence and identification of a termite hazard, test specimens (35 x 35 x 250 mm³) are installed vertically in the ground adjacent to and in contact with bait specimens of the same dimensions and interconnected by susceptible feeder str...

International collaborative laboratory comparison of two wood preservatives against subterranean termites: Third update and first report
1996 - IRG/WP 96-10174
At the 24th annual meeting of IRG in Orlando, USA, in May 1993 an international subterranean termite laboratory bioassay to compare the various preferred termite protocols used by IRG termitologists was initiated. The author was nominated to co-ordinate this comparative laboratory evaluation of two wood preservatives, copper-chrome-arsenic (CCA) and copper naphthenate (Cu-Na) against the subterran...

Detection of feeding behaviour of termites using AE monitoring
1991 - IRG/WP 1514
Using acoustic emission (AE) monitoring, the feeding activity of the termite inhabiting a wood specimen was investigated. The amplitude and the rate of AE from the specimen of Coptotermes formosanus Shiraki was larger than that of Reticulitermes speratus Kolbe. The AE event rate was higher in the specimen with soldiers than without soldiers. The AE event rate decreased according to the resistance ...

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...

Termite resistance of pine wood treated with chromated copper arsenates
1997 - IRG/WP 97-30128
Two four-week, no-choice laboratory tests were performed with CCA-treated southern yellow pine and radiata pine against Formosan subterranean termites, Coptotermes formosanus. CCA retentions as low as 0.05 kg/m3 (0.03 pcf) provided protection from all but light termite attack (rating of 9 on a 10-point visual scale). Similar and consistent light attack on wafers containing retentions as high as 6....

Termite trail-following substances in Houttuynia cordata
2001 - IRG/WP 01-10409
Termite trail-following active compounds in the plant, Houttuynia cordata Thunb., were studied by a combination of chemical analyses and bioassay using Coptotermes formosanus Shiraki as a test termite. We have found that termites were attracted to methanol extracts from H. cordata. The n-hexane(Hex) extracts, that showed a trail-following activity, were fractionated by a silica-gel column chromato...

Evidence supporting the use of termite baiting systems for long-term structural protection
2000 - IRG/WP 00-10377
The efficacy of the Sentricon Colony Elimination System containing Recruit II termite bait (0.5% hexaflumuron) in controlling active subterranean termite infestations has been demonstrated in numerous studies. This baiting system and other termite baiting systems are now widely used, and generally accepted, tools for remedial termite control in North America, Hawaii, and other parts of the world. ...

Response of the Formosan Subterranean Termite (Coptotermes formosanus) to Cellulose Insulation Treated with Boric Acid in Choice and No-Choice Tests.
2004 - IRG/WP 04-10532
The tunneling ability of the Formosan subterranean termite Coptotermes formosanus Shiraki through a cellulose insulation material containing11.1% boric acid was tested in choice and no-choice bioassays. We examined tunneling behavior and mortality of termites exposed to treated and untreated insulation material in miniature simulated wall voids. In a choice test termites tunneled through untreat...

Development of a Granitgard® particulate termite barrier for use in tropical Australia
1997 - IRG/WP 97-10190
Granitgard® is superficially simple technology; graded crushed aggregate, sieved to a size range impenetrable to subterranean termites. However, behind this apparent simplicity lies a large research effort. In this paper we describe the laboratory development of a grading of Granitgard suitable for use against the wide range of termites which attack timber in northern Australia, above the Tropic ...

Feeding preference behaviour of Crytopermes cynocephalus Light and Coptotermes curvignathus Holmgren on twenty-eight tropical timbers
1985 - IRG/WP 1251
A study on the feeding preference behaviour of a dry-wood termite Cryptotermes cynocephalus Light and a subterranean termite Coptotermes curvignathus Holmgren on 28 species of tropical timbers has been conducted. The weight-loss of individual timber and the mortality of termite was·recorded after 5, 10, 15, 20 and 25 days of exposure. The results reveal that there are only five species among 28 s...
Microcapsule formulation of fenitrothion as a soil termiticide
1991 - IRG/WP 1478
The efficacy and the mode of action of a microcapsule formulation of fenitrothion against Coptotermes formosanus Shiraki were investigated. The physicochemical property that this formulation does not allow the active ingredient to diffuse through the capsule wall contributed to a long lasting efficacy and safety for the men spraying. The residual effect of the fenitrothion microcapsule in soil was...

A method for screening termite baits using Coptotermes lacteus mounds
1984 - IRG/WP 1237
A method with several variations designed to rapidly screen potential bait substrates using Coptotermes lacteus mounds is described. The equipment used in this method is relatively inexpensive, readily prepared in the laboratory, and easily installed into active mounds in the field. Bait substrates are in continuous contact with a 'high termite hazard', and may be monitored with ...
