Control of termite attack using a trapping method and acoustic emission (AE) monitoring a case study at an electric power plant
1997 - IRG/WP 97-10224
To prevent subterranean termites (Coptotermes formosanus Shiraki and Reticulitermes speratus Kolbe) from invading the buildings of an electric power plant and to control their attack, artificial traps were buried around the buildings. The attack of the termites in and around the traps was monitored by detecting acoustic emissions (AE) generated by the feeding behavior of the workers. The cylindric...

Field Trials with mini-stakes
2002 - IRG/WP 02-20244
In 1995 an extensive field test program with wood mini-stakes, 8 x 20 x 200 mm, was started. In these trials a large number of parameters are being evaluated, including several new wood preservatives, differently chemically modified woods and natural durability of various wood species. The test sites are three fields in Sweden for in-ground and “close to ground” testing, one subterranean termi...

New applications of silafluofen to termite control
2001 - IRG/WP 01-30274
Silafluofen-based termiticides are widely used for soil and timber treatments in Japan, as silafluofen possesses advantageous properties of low fish toxicity and high chemical stability (to light, in soil, in alkaline environments, etc) in addition to high termiticidal activity and low mammalian toxicity. As new applications of silafluofen to termite control, we have developed another type of prod...

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...

Termite field evaluations in hawaii: A brief review of methods and issues
1995 - IRG/WP 95-10131
The severe termite hazard in Hawaii, principally due to the presence of the Formosan subterranean termite (Coptotermes formosanus Shiraki), has long required the use of preservative-treated lumber in building construction. This hazard has also favored and stimulated field research in Hawaii on methods of protection from termite attack, including evaluation of soil insecticides and treated wood und...

Intrigue Dust - A new method of eradicating subterranean termite (Isoptera: Rhinotermitidae) colonies
2001 - IRG/WP 01-10396
Arsenic trioxide is used by pest controllers in Australia to eradicate subterranean termite colonies. In 2000 Bayer Australia introduced Intrigue Termite Dust as a more environmentally acceptable alternative. Intrigue, containing 80% triflumuron, a chitin synthesis inhibitor, disrupts the moulting process in termites. Dusted termites return to the nest and pass around triflumuron via mutual groomi...

Mobility of zinc borate wood composite preservative
1997 - IRG/WP 97-30153
Zinc borate (ZB) is being used as an antifungal and insecticidal wood preservative for flake/strand-based composites. Data is reported on the laboratory and field leaching behavior of ZB when contained in apen flake composites. In general, the performance results correlate with leaching hazard. Although the boron in ZB is more resistant to depletion than in sodium borates, the ZB boron will deplet...
