Field testing of soil insecticides as termiticides
1986 - IRG/WP 1294
This paper reviews field methods used to evaluate soil insecticides as termiticides by the U.S. Department of Agriculture, Forest Service, Gulfport, Mississippi. Field tests are conducted on a minimum of five "nationwide sites" in the United States to determine the efficacy of chemicals in various soil types and against different termite species. Test results of selected insecticides are presented...

The role of toilet paper in studies of desert subterranean termites in Arizona, USA
2000 - IRG/WP 00-10375
Toilet paper rolls were used as a substrate for observing foraging activity of Heterotermes aureus (Snyder) and Gnathamitermes perplexus (Banks) in the Sonoran Desert of Arizona. Foraging was minimal during the winter months, increased in the spring, was high but erratic in the summer, and then was moderate again in the fall. H. aureus foraged within a temperature range of 7.6° to 47°C, G. perpl...

1986 - IRG/WP 1292
In comparison to chlorinated hydrocarbons insecticides of the compound classes organophosphates, carbamates and pyrethroids were tested according to an earlier described soil-test in the laboratory. The following termite-species were used: Heterotermes indicola, Reticulitermes santonensis and in addition Reticulitermes flavipes, Reticulitermes lucifugus, Reticulitermes speratus and Coptotermes for...

The effectiveness of deltamethrin against subterranean termites (final report)
1993 - IRG/WP 93-30011
Two series of block tests of Pinus sp were treated by dipping them for 1 (one) minute in a solution with 0.015 (w/w) and 0.05 (w/w) of deltamethrin, respectively. In both cases, an average retention of 47 kg/m³ (0.32 l/m) was reached. One part of the block tests remained under laboratory conditions during 9 months, and the other was stored during equal period of time in a theater basement submitt...

The evaluation of non-rubber extractives from the guayule plant (Parthenium argentatum Gray) for pesticidal worth
1986 - IRG/WP 4125
The resin obtained from the guayule plant (Parthenium argentatum Gray) of the southwestern United States is a potentially imporant domestic source of natural rubber, however only about 20 percent of the extractives from the plant produce this material. An effort is underway to find marketable uses for the remaining non-rubber extractives, and the Naval Research Laboratory is evaluating this resin ...

1987 - IRG/WP 1323
This paper reports efficacy data from the field evaluation of various soil termiticides by the U.S. Department of Agriculture, Forest Service, Gulfport, Mississippi. These chemicals, which include a number of chlorinated hydrocarbon, organophosphate, pyrethroid, and carbamate insecticides in a range of concentrations, have been in long-term tests at seven field sites. Data are reported for the gro...

Termite physical barriers: Update on retrofitting Granitgard around 'mock up' buildings after four years
1996 - IRG/WP 96-10140
This field experiment was installed four years ago (March 1992) to evaluate the effectiveness of graded crushed granite stone, commercially marketed under the name, Granitgard, as a physical termite barrier when retrofitted around 'mock-up' buildings. The field site is located at Walpeup in the semi-arid mallee region of north-west Victoria (360 km from Melbourne), and there are ...

Depth of foraging of subterranean termites in tropical Australia
1996 - IRG/WP 96-10141
Stakes of radiata pine (Pinus radiata D.Don) of varying lengths to 800 mm were inserted vertically in the soil with all but their lower 100 mm sheathed in a capped UPVC tube representing a physical barrier to termites. In one series of trials, termites were encouraged to aggregate at the upper ends of the tubes, in order to determine whether they would descend to the lower end of the barrier. In a...

Evaluation of tropical wood by-products as a potential source for termite control products
2001 - IRG/WP 01-10408
Termites damaging in houses represent an ever growing threat in Europe, where the phenomenon has accelerated during the last ten years, as well as in the tropics, where infestations are permanent. To fight against this plague, the current methods used, through injection of organochloric or organophosphorized products into the timber structures and walls, are belonging to the past due to the toxici...

Major insects attacking timber used for building purposes and a practical approach for their control
1990 - IRG/WP 1449
Lignocellulosic materials like wood, bamboos, palmyra palms, reeds, leaves and grasses have been the oldest materials used by human beings. Although with the rapid pace of industrialisation, specially in several western countries, wood began to be replaced with alternative materials like cement, steel etc. yet its use has not vanished even in highly developed countries. Some of the reasons for thi...

Protection for whole-of-house timbers from subterranean termites in Australia
2005 - IRG/WP 05-20315
A field study was designed to increase maximum protection of whole-of-house timbers against subterranean termites. Concrete slab and suspended floor simulated houses were constructed using untreated and treated (slow acting toxicants) timber frames. The treated and untreated timber structures within the simulated houses were exposed with or without soil chemical and/or physical barriers in the fie...

Deltamethrin effectiveness against subterranean termite attack on wood under natural conditions
1989 - IRG/WP 1407
On fighting subterranean termites on wood, out of ground contact, the synthetic pyrethroid Deltamethrin shows positive aspects such as its efficiency and low mammalian toxicity. To evaluate its performance in conditions very similar to those in service use, specimens of Pinus sp were treated with solutions of Deltamethrin diluted in "white spirits" at 0.005% (w/w) and 0.01% (w/w) and exposed in a ...

Whole-of-house protection from subterranean termite attack and damage after four years of field exposure
2008 - IRG/WP 08-10665
This study reports the condition of the whole-of-house termite protection test in tropical Australia after four years. The study was designed to provide maximum protection to whole-of-house timbers in a natural situation posing the highest hazard from subterranean termite populations.

Antitermitic activities of Shisham (Dalbergia sissoo Roxb.) heartwood extractives against two termite species
2016 - IRG/WP 16-10856
Shisham (Dalbergia sissoo) heartwood extractives were investigated for antitermitic activities against Heterotermes indicola and Reticulitermes flavipes. Heartwood extractives were removed from wood shavings by soxhlet extraction using (2:1) ethanol: toluene as the solvent system. Filter paper bioassays were conducted against both species to observe concentration dependent feeding response and mor...

Effects of teak, Tectona grandis Linn, heartwood extractives against Heterotermes indicola (Isoptera; Rhinotermitidae)
2018 - IRG/WP 18-10910
Heartwood extractives from Tectona grandis were investigated for antitermitic activities against Heterotermes indicola in laboratory experiments. Extractives were removed from wood shavings by soxhlet extraction using an ethanol: toluene (2:1) solvent system. Termite feeding and mortality followed a concentration dependent response. The highest termite mortality occurred at an extractive concentra...
