Evaluation of two populations of Reticulitermes santonensis De Feytaud (Isoptera) by triple mark-recapture procedure
1997 - IRG/WP 97-10237
The optimisation and use of biocides is linked to the improvement in our understanding of the target organism. With this in mind we have studied 2 populations of the termite Reticulitermes santonensis De Feytaud. The first inhabiting an urban territory, the trees lining Ave. Boutroux in Paris. The colony has been estimated at 1,200,000 +/- 130,000 insects by triple mark-recapture procedure, foragi...

Biocontrol of Reticulitermes santonensis by entomopathogenic fungi - Improvement of the contamination process
2000 - IRG/WP 00-10359
The entomopathogenic fungi Metarhizium anisopliae and Beauveria bassiana were selected for their potential to control the subterranean termite Reticulitermes santonensis. The research work aims to increase the mortality of termites by improving the contamination process inside a termite colony. The transfer of fungal spores from contaminated termites to a whole colony of termites was thus studied....

Biocontrol of Reticulitermes santonensis by entomopathogenic fungi
1999 - IRG/WP 99-10324
Biocontrol of subterranean termites by entomopathogenic fungi has already been studied but little work has been done on Reticulitermes santonensis. This paper deals with the screening of 8 fungi strains for their pathogenicity towards R. santonensis. Spores from Metarhizium anisopliae, Beauveria bassiana and Absidia coerulea were used to contaminate 25 termite workers in petri dishes. Bioassays we...

Bi-oleothermal treatment of wood at atmospheric pressure: resistance to fungi and insects, resistance to weathering and reaction to fire results
2008 - IRG/WP 08-40418
Bi-oleothermal process is a simple treatment which has been developped by CIRAD in cooperation with FCBA. It allows a deep impregnation of wood with hydrophobic products using cheap facilities. The process includes two steps at atmospheric pressure. The first one is a dipping of wood samples in a hot oil bath (between 110 °C and 200°C) which creates an overpressure inside the wood. The second on...

Termite legislation in France: Termite control measures and prevention rules in building construction
2010 - IRG/WP 10-20448
Reticulitermes subterranean termites are considered as urban pests in France because they are harmful for wood-based in the South and the southwestern quarter of the country. Since November 2006 new protective measures of building construction have been introduced by the French parliament which must be applied across the country and in overseas territories to prevent termite infestations. All new ...

Laboratory evaluation of the natural durability and treatability of Cryptomeria japonica grown in La Reunion Island
2012 - IRG/WP 12-10772
The Japanese cedar Cryptomeria japonica is the main resource for timber construction in La Reunion Island, an overseas territory belonging to France. The natural durability of C. japonica originating from East-Asia has been considered so far as quite poor and the European standard EN 350-2 classifies this species ‘not durable’ with regard to its resistance to termites, xylophageous beetles and...

Termite and insect resistance of acetylated wood
2015 - IRG/WP 15-40703
The benefits from acetylation of wood to enhance resistance against fungal decay and dimensional stability have been known for many years. Since 2007 Accsys Technologies has been commercially producing Accoya® wood that is based on acetylation of radiata pine. A number of studies on the resistance of acetylated wood to attack by wood destroying termites have been conducted, but there is no common...

Evaluation of the Virulence of the Termite Species Occurring in the French Tropical Overseas Territories
2018 - IRG/WP 18-10913
The French tropical overseas territories are strongly affected by termites’ activity, which is especially devastating because the species encountered there are among the most virulent in the world. That is why in these regions it is particularly important that producers and users of wood-based products are provided with materials and preservative products whose durability and efficacy has been t...

Conversion by insects – alternative method for wood waste up-cycling
2018 - IRG/WP 18-50337
Building industry is a major consumer of materials and waste generator in Europe. The bio-based building materials are considered as interesting alternative in modern building sector due to their low environmental impact. However, in order to increase confidence for bio-based materials application, they should present satisfying performance during service life allowing at the same time their casca...

Assessing the Performance of Wood-based Materials Exposed to Termite Risk – A New Experimental Approach
2022 - IRG/WP 22-10989
Termites are able to degrade a large number of building materials including wood, wood-based panels, biobased insulation, and polymers. The risk for a material of being degraded by termites depends on its composition, on its accessibility, and also on the behavior and the biology of the termite species considered. Within the EU project Click Design, we investigated the durability, under laboratory...
