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 ...

Preventing decay in termite monitoring stations
2010 - IRG/WP 10-30546
In-ground monitoring stations and termite baits are widely used in the southern United States with the intent of detecting and eradicating subterranean termite activity near buildings. These stations comprise a wood (or other cellulose material) substrate (monitor) and perhaps a termiticidal toxicant (bait) held in a plastic cage that allows for both easy examination and access by termites. The us...

Towards designing eco-friendly buildings with in-built termite protection
2010 - IRG/WP 10-50273
The increase in greenhouse gases, leading to global warming, is considered by a consistent scientific worldview not due to natural variation, but due to the growing concentration of carbon dioxide (CO2), methane (CH4) and other atmospheric pollutants. Global emissions of carbon dioxide from fossil fuel combustion and cement production rose from 22.6 billion tons in 1990 to an estimated 31.2 billio...

The importance of proper taxonomic identification, a case study with Reticulitermes spp. from USA
2012 - IRG/WP 12-10774
Taxonomy has been evolving with recent advancement in molecular and internet technologies. The importance of a stable taxonomic foundation is unquestionable as this science provides crucial information about evolutionary relationships and allows questions about the life history and ecology of organisms to be asked. We hope to highlight the issues and lessons we have learned from revising the taxon...

Decay factors in termite in-ground monitoring stations
2012 - IRG/WP 12-10775
Subterranean termites are serious pests of wood in service in much of the world. One of the most common techniques for monitoring and controlling termites is the use of in-ground monitoring stations which comprise a wood or other cellulosic material monitor (cellulosic matrix) and/or a termiticide bait held in a open plastic holder so facilitates examination and the termite access. Wood and other ...

Effects of geographical and dietary variation on the symbiotic flagellate protists communities of the subterranean termite Reticulitermes grassei Clément
2015 - IRG/WP 15-10847
Despite their importance on diverse ecosystems, termites may also be considered severe pests of wood in service, and also as agricultural and forestry pests.
Subterranean termites’ ability to digest lignocellulose relies not only on their digestive tract physiology, but also on the symbiotic relationships established with flagellate protists and bacteria. In this tripartite lignocellulolytic sy...

Termite Management and the U.S. Experience: A Case for Wood Treatment & Integrated Control
2015 - IRG/WP 15-30678
A brief overview of termite control is given using specific experiences from the U.S.A. Five major types of termite treatment now prevail: soil applied chemical barriers, in-structure chemical barriers (in-situ applied wood and foundation treatments), physical barriers, treated wood and termite baits. In general, ‘stand-alone’ pretreatments or ‘primary’ treatments are often discussed and ...

Diversity of hindgut symbiotic flagellate protist communities of the European subterranean termite in Portugal
2016 - IRG/WP 16-10875
The flagellate protist communities are an important part of the termite, as they lead the lignocellulose digestion. Termites (Reticulitermes grassei) were sampled from forest and urban environments in mainland Portugal where they are native and in Faial Island, Azores (invasive populations). Termites’ gut contents was analysed morphologically and the diversity of the flagellate protist community...

Elimination of colonies belonging to higher termite group using insecticide bait: A short review
2018 - IRG/WP 18-10908
Controlling termite infestation by using baiting method is gaining popularity around the world. Lower group of termites particularly belonging to the genus Coptotermes have proven to be easy to control by this method due to their nature of feeding. However termites belonging to higher group, such as those under Termitidae were initially thought to be a challenge as they mostly fed on fungal garden...

Response of the symbiotic flagellate protists community of subterranean termites to sublethal amounts of biocides
2018 - IRG/WP 18-10911
Subterranean termites are quite efficient at extracting nutrients from lignocellulose. Their ability relies not only on the digestive tract physiology but also on symbiotic relationships established with flagellate protists and bacteria. This work aimed to screen the response of the flagellate protists community of the subterranean termite Reticulitermes grassei Clément to the ingestion of differ...

Evaluation of the effect of zwitterionic buffers on termite gut protists
2018 - IRG/WP 18-10933
The thermal modification of wood is recognized as the most commercialized wood modification process. The treatment of wood at temperatures usually greater than 180 ºC results in a product with some properties enhanced (dimensional stability, durability, aesthetical colour) and some diminished (mechanical properties). The loss of mechanical strength is recognized as a limitation to the use of ther...
