Estimation of oral toxicity of boron as a bait toxicant and the trophallactic effects between individual members of termite colonies.
2003 - IRG/WP 03-10495
In recent years, because of the favourable environmental characteristics of boron, researchers in the wood preservation industries have refocussed on the use of boron as a major wood preservative against wood-destroying insects. Currently the greatest use of boron compounds is in remedial treatments. Boron has been found to have slow-acting toxicity against subterranean termites. Because of thi...

Transfer of thiamethoxam from exposed to non-exposed workers of Microcerotermes diversus Silvestri (Isoptera: Termitidae)
2012 - IRG/WP 12-10783
Because Microcerotermes diversus (Silvestri), a subterranean termite, is able to attack cellulosic materials, it is destructive to structures and the most economically important wood pest in Iran. Therefore, control or management of the termite is a serious public concern. The use of nonrepellent termiticides such as thiamethoxam (a neonicotinoid compound) has been gaining popularity in recent yea...

Exposure monitoring of creosote vapors
1989 - IRG/WP 3511
Creosote oils contain hundreds of compounds. During impregnation and handling of treated wood the main component in the vapors released in air is naphthalene. Other main components are alkyl naphthalenes, indene, phenol and its methyl derivatives, benzothiophene, diphenyl, acenaphthalene and fluorene. In the measurement of creosote vapors, naphthalene can be used as an indicator agent. One of the ...

Size of food resource determines brood placement in Reticulitermes flavipes (Isoptera: Rhinotermitidae)
2000 - IRG/WP 00-10351
Most species of subterranean termite house and care for larvae in specialised chambers or complex nurseries. In addition to these chambers, the genus Reticulitermes also keeps larvae at sites where foragers are feeding, a trait more commonly found in damp wood and dry wood termites. This phenomenon of holding larvae at foraging sites is quite well known among researchers who work with Reticuliterm...

Cancer incidence among CCA exposed workers in the wood preserving industry
1995 - IRG/WP 95-50040-09
CCA wood preservatives - Copper, hexavalent, Chromium and tri-or pentavalent, Arsenic - has been used in the Nordic countries since mid 1930. Trivalent arsenic and hexavalent chromium compounds are toxic and cancerogenic while pentavalent arsenate and trivalent chromium are less hazardous. In impregnation, the compounds of CCA are fixed in the wood as insoluble trivalent chromium and copper pentav...

Creosote and cancer -Cancer incidence among workers exposed to creosote
1990 - IRG/WP 3572
Creosote is a wood preservative that contains polycyclic aromatic hydrocarbons, which are known to be carcinogenic. Cancer incidence among 919 male workers in Sweden and Norway exposed to creosote in the wood preserving industry was studied. The expected numbers of cases were based on the incidence rates of cancer according to the Cancer Registries of Sweden and Norway. A total of 129 cancer cases...

Evaluation of literature on adenocarcinomas in wood workers
1997 - IRG/WP 97-50092
Occupational exposure to wood dust alone or chemically treated is suspected to be associated with an increased risk of developing adenocarcinoma of the nasal cavity, which in the general population is very rare; fewer than 10% of nasal cancer deaths are adenocarcinomas, which have an annual incidence of 1-2 per million. However, the epidemiological data available are not sufficient to make a defin...

Determination of the lethal dose of fipronil for workers of Coptotermes formosanus (Isoptera: Rhinotermitidae
2007 - IRG/WP 07-10616
This document is a combination of two articles previously submitted to the journal, Sociobiology. Lethal dose of fipronil was determined in two experiments: topical application and contact with treated sandy loam. In the topical application the toxicity of fipronil was evaluated against workers of a laboratory colony of Coptotermes formosanus Shiraki. Fipronil was applied by the microsyringe to t...
