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...

Impact of water holding capacity and moisture content of soil substrates on the moisture content of wood in terrestrial microcosms
2019 - IRG/WP 19-20662
Terrestrial microcosms (TMC) are frequently used for testing the durability of wood and wood-based materials as well as the protective effectiveness of wood preservatives. In contrary to experiments in soil ecology sciences, the experimental set-up is usually rather simple. However, for service life prediction of wood exposed in ground, it is of immanent interest to better understand the different...

Silicate coatings for wood substrates
2020 - IRG/WP 20-40906
Silicate coatings are surface finishing products containing alkali metal silicates or ethyl silicates as main binders. They are traditionally designed and well established for mineral substrates or corrosion protection of steel. The interest for these coatings in wood field is growing because of the benefits they could provide such as high durability, weathering resistance and fireproofing and sus...

Control of Asian subterranean termites Coptotermes gestroi (Blattodae: Rhinotermitidae) by a new generation bait system with vegetal extracts-diflubenzuron mixture
2023 - IRG/WP 23-30797
The efficacy of anti-termite bait pebble dosed at 0.3% w/w of Diflubenzuron, and Chitin Synthesis Inhibitor (CSI) and 0.6% w/w of vegetal extract from Berkem Biosolutions®, was evaluated in the laboratory on the Asian subterranean termite Coptotermes gestroi (Wasmann). Four concentrations 33.3%, 50%, 50% bis and 100% as well as two neutral matrices, were used in two in-house developed test method...

Optimization via artificial intelligence of intumescent coatings for wood substrates
2023 - IRG/WP 23-40987
The development of new materials requires a large amount of experiments representing a major issue to innovate. This is particularly true for complex material formulations such as flame retarded materials that could contain a number of ingredients. Artificial Intelligence based optimization (more precisely Bayesian optimization) techniques appear to be efficient methods to optimize complex systems...

Laboratory evaluation of PA1b, an insecticidal protein extracted from pea seeds (Pisum sativum), as bait active ingredient against the subterranean termite Coptotermes gestroi (Blattodea: Rhinotermitidae) in tropical zones
2024 - IRG/WP 24-11038
Coptotermes gestroi (Wassman 1896) is one of the worst pests in tropic areas, economically. Two types of curative methods are used since decades to eliminate colonies that attack constructions: injection of biocidal treatment solutions on wood, walls and soil, and population control using baits. In application of the current regulations, the first technique can no longer be used in Europe, to lim...

Efficacy performance of Pea Extract as bait toxicant for termite control in Reunion Island
2024 - IRG/WP 24-11050
This study was carried out to determine the toxicity of Pisum sativum L., extract (Pea Extract) for the subterranean termite, Coptotermes gestroi (Isoptera: Rhinotermitidae). Yellow field peas (Pisum sativum L.) are particularly rich in protein. A solid-liquid hydroalcoholic extraction process was employed on the dried form of pea seeds to obtain one particular peptide PA1b (Pea Albumin 1, subunit...
