Antinomic natural self-protection mechanism in long-lasting woods: a case study with three tropical species from French Guiana
2009 - IRG/WP 09-10696
We demonstrate in this work through 3 examples that Amazonian trees may specialize long-lasting woods by means of at least to different approaches. Wallaba impregnates its wood with large amounts of weakly antifungal compounds acting in synergy, while tatajuba and louro vermelho woods are naturally impregnated with antifungal agents. Comparison of biological activities in vitro and concentrations ...

Natural durability of Sextonia rubra, an Amazonian tree species: description and origin
2017 - IRG/WP 17-10887
Sextonia rubra is a tropical tree species belonging to Lauraceae family. In French Guiana, its long lasting heartwood is largely exploited for different purposes including house construction, and furniture making. Decay tests have confirmed S. rubra natural durability, and led us to discover some variability. Rubrynolide and rubrenolide, which are two majors metabolites isolated from the heartwood...

For the understanding of biological strategies to sustainable pest management: the case of Nasutitermes corniger
2018 - IRG/WP 18-10907
Termites have long been a serious pest of wooden constructions, timber products and are still causing an important problem in most of tropical regions. The genus Nasutitermes is among the most abundant wood-feeding Termitidae in South of America. The first aim of this review was to gain new insights into the management of N. corniger, considered to be the most economically detrimental pest of this...
