From wood protection to health protection: larvicidal potential of formulations containing Sextonia rubra wood residues extract against Aedes aegypti mosquitoes
2020 - IRG/WP 20-10968
French Guiana is a French overseas territory almost entirely covered by Amazonian rainforest and characterized by its incredible biodiversity. Several woody species harboured by this tropical forest are exploited sustainably for timber industry. They are commercialized notably for carpentry and outdoor applications because of their remarkable natural durability. Among them, stand Dicorynia guianen...

Sustainable wood products development in a bio-refinery perspective: case studies in French Guiana
2022 - IRG/WP 22-50370
French Guiana, by its belonging to the Amazon region and the Guiana shield, has very specific environmental and social characteristics in the French regional ensemble. In this context, it is thus necessary to find how to reconcile the economic development of the territory, the conservation of biodiversity and the recognition of local knowledge and practices. Bringing together multidisciplinary ski...

Screening-method for the examination of the resistance against contact-insecticides of Lyctus brunneus Steph. beetles
1981 - IRG/WP 2148
A serie of filter-paper rondelles is treated with different concentrations of an organic insecticide dissolved in aceton. Beetles of Lyctus brunneus are put onto the dry surfaces. During the impact of the poison the knock-down is observed and after a following poisonfree holding, the knock-down and mortality are registred....

Developments in wood preservation
1977 - IRG/WP 393
The purpose of this paper is to comment very briefly upon recent developments and trends in wood preservation so that members of this Working Group have a basic knowledge of activities in other countries. The last paper was prepared in April 1976 and the present paper refers to developments, since that time....

A critical review of the AWPA standard method (M12-72) for laboratory evaluation to determine resistance to subterranean termites
1986 - IRG/WP 1298
The American Wood Preservers' Association standard (M12-72) for evaluation of candidate wood preservatives against subterranean termites is reviewed and suggestions for revision are made. The most serious flaws in the current test procedure involve a failure to recognize inter- and intraspecific variation and a lack of quantification of test results....

The permanence of permethrin in wood preservation
1984 - IRG/WP 3288
The permanence of the synthetic pyrethroid permethrin in treated wood has been assessed for double vacuum and immersion treated Scots pine sapwood and whitewood using a 0.5% m/m solution of the insecticide in a hydrocarbon solvent. It is concluded that for all but the outermost 0.5 mm of the treated battens the distribution of the permethrin is relatively permanent. The outermost 0.5 mm appears vu...

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...

Metal carboxylates for wood pest control
1996 - IRG/WP 96-30109
Metal carboxylates have been used as wood preservatives for more than fifty years. Predominantly salts of naphtenic acids have been commercially applied so far. They have water repellent as well as fungicidal and insecticidal properties. In the last years, metal carboxylates of saturated fatty acids were introduced. Fatty acids with 7-10 carbon atoms already have fungicidal activity by themselves....

The preliminary evaluation of selected sulfonium salts for use in wood preservation
1984 - IRG/WP 3278
Five sulfonium compounds, including two sulfonium methosulfates, one sulfonium bromide and two amphoteric sulfonium propanesulfonates, were prepared in crude form and subjected to various biocidal screening tests. A rapid screening test in which treated Pinus radiata pulp pellets were exposed to one of three wood-decaying fungi growing on malt agar revealed that dodecyl dimethyl sulfonium methosul...

Remedial treatment of wood attacked by insects
1981 - IRG/WP 3175
A review is presented of remedial treatments against wood-boring insects in wood in service. Preconditions and fundamental principles of insect control are compared with the control of fungal attack and reasons are given for the fact that remedial treatments against insects are more commonly applied than against fungi. With regard to insect control measures with a simultaneous preventive effective...

The Use of Insect Hormones as Non-Neurotoxic Insecticides in Wood Preservatives
2002 - IRG/WP 02-30277
The ecdyson and juvenile hormone analogues show a clear difference in their effect on the house borer, Hylotrupes bajulus. In the tested dosages, the ecdyson analogues have only a slight ovicidal effect but a very clear effect on old larvae. With a dosage of 1250 mg/m², Halofenozid achieved 100% mortality after 27 weeks and Tebufenozid after 40 weeks. The two juvenile hormone analogues, Fenoxy...

The preventive actions of three commercial wood preservatives against Dinoderus minutus
1984 - IRG/WP 1233
Dinoderus minutus is one of the most common pest insects for the bamboos. For preventing the damages of this insect, the preventive treatment of bamboos with preservatives is necessary. But because of the environmental reasons, only limited insecticides are available in Japan. The author determined the preventive effects of three commercial products against Dinoderus minutus by the medium of the B...

Evaluation of chlorpyrifos as an insecticidal component of a wood preservative
1984 - IRG/WP 3301
After two years of laboratory and field testing, chlorpyrifos is showing excellent potential as an insecticidal treatment to wood. In laboratory termite tests, retentions as low as 1-2 parts-per-million or approximately 0.0008 kg/m³ (0.00005 lbs/ft³) are effective against the Coptotermes formosanus. Laboratory leaching tests have shown no significant effect on the concentration of the retained c...

Evaluating possibilities of leaching of deltamethrin and TCMTB (insecticides and fungicide for protecting wood) by rain water or by soaking in water
1988 - IRG/WP 3464
Deltamethrin and TCMTB have been subjected to several field leaching tests on freshly fallen trees and in the laboratory, using standard EN 84. All the trials gave the same results and confirm that Deltamethrin and TCMTB are not washed out after they have been allowed to penetrate the trunk surface properly. According to the EN 84 standard, less than 1% Deltamethrin and less than 1.7% TCMTB were r...

The compatability of tributyltin fungicides and synthetic pyrethroid insecticides as wood preservatives
1987 - IRG/WP 3414
The stability of three synthetic pyrethroids, cypermethrin, deltamethrin and permethrin, to selected tributyltin compounds, Bu3SnX {where X = OSnBu3, Cl, 02CC6H5, O2C (Naphthenyl), OSO2Et}, (Bu3SnO)3PO and {NBu4} {Bu3SnCl2}, in toluene solution was investigated by infra-red spectroscopy over a six month period. It was found that only (Bu3Sn)2O reacted with the pyrethroids and that their order of r...
