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...

Termite control in the post-organochlorine era: How do we advise industry and society?
1990 - IRG/WP 1435
Organochlorines have been severely restricted and banned in many States in North America, and replaced by organophosphates and synthetic pyrethroids. This situation may occur in Australia, and elsewhere, in the not too distant future. Just how do we as entomologists advise the industry and society in termite control in the post-organochlorine era? A brief historical overview of pesticide bans and ...

Biocidal screening method of wood extractives by a direct use of cellulose TLC plate
2001 - IRG/WP 01-20226
Most of the methods to evaluate the biological durability of woods have focused on decay fungi and termite as deteriorating organisms and it is well known that one of the most important factors affecting the biological characteristics of wood is extractives. Bioassays for evaluating the biological activities of wood extractives have been mainly conducted with treated filter papers for termites or ...

Options for termite management using the insect pathogenic fungus Metarhizium anisopliae
1996 - IRG/WP 96-10142
The insect pathogenic hyphomycete fungus Metarhizium anisopliae (Metschnikoff) Sorokin is promising as a biological insecticide for many species of subterranean termites. In Australia, a survey of termite mounds and feeding sites using a selective medium showed that this fungus is widespread but rarely causes mortality of termites under natural conditions. One isolate, codenamed FI610, has been se...

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...

Sulfluramid, a new bait concept for the control of termites
1995 - IRG/WP 95-30075
The annual cost of preventing, controlling and repairing the damage done by termites in the United States of America is in the billions of dollars. Current termite control methodology is generally effective in the control of termite activity. However, new technology (termite foams, termite baits, physical barriers) is emerging which has or will provide new tools to control termites. This report ce...

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...

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...

Evaluation of Rosewood extractives as potential source for termite control
2003 - IRG/WP 03-30323
Rosewood (Aniba rosaeodora) is an extremely durable tropical timber species that has been widely used in the past in perfumery on account of its high proportion of essential oil. The aim of this study was to evaluate the efficacy of the extractives from rosewood as possible active ingredients for termite control.
Some rosewood sawdust has been extracted using different solvents and methods. The e...

Subterranean termite foraging behaviour and the development of baiting methods used for termite control by the Division of Forest Products
1994 - IRG/WP 94-10058
Given the premise that alternatives to current subterranean termite control measures using organochlorine insecticides and arsenic trioxide have been actively researched by our Division for over ten years, emphasis on baiting methods in controlling these termites has been a major facet of our research. Recently, the new Australian Standard (AS 3660 -1993) was released which outlined the use of phy...

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...

Field evaluation of several bait toxicants for subterranean termite control: A preliminary report
1988 - IRG/WP 1376
Since 1983, field studies have been conducted to evaluate the effectiveness of several bait toxicants in reducing subterranean termite populations at the Chipola Experimental Forest in Florida. Tests with fenoxycarb (Ro 13-5223), Ro 16-1295, and Avermectin B1 indicated that fenoxycarb showed the most promise. Large numbers of presoldiers and intercastes have continued to occur in plots treated wit...
