<br/><br/> <br/><br/>ABSTRACT<br/><br/>Some Amazonian woods are considered highly resistant to the attack of microorganisms; however,<br/>which ones present the highest resistance is unknown. This study aimed to evaluate the natural<br/>resistance of seven woods to xylophagous termite Nasutitermes octopilis through a no-choice feeding<br/>assay. The following wood species were assessed: Dinizia excelsa, Manilkara huberi, Dipteryx odorata,<br/>Bagassa guianensis, Astronium lecointei, Caryocar villosum, and Hymenolobium   petraeum<br/>(Ducke). To this end, five timber samples from the middle heart at breast height of each plant<br/>with dimensions of 2.54 × 2.54 × 0.64 cm (longitudinal × radial × tangential) were collected from<br/>sawmills in the municipality of Altamira, Pará state, Brazil, submitted to termite action under<br/>laboratory conditions, and had their mass loss and wear assessed, with five replicates. A. lecointei<br/>showed the lowest resistance, whereas C. villosum and D. odorata presented the highest resistance.<br/><br/>Keywords: biodeterioration, xylophagous termites, no-choice feeding assay, Amazonian wood.
