- Abstract
The objective of this work was to analyze the deterioration caused by termites in woods of Mezilaurus itauba (Meisn.) Taub. ex Mez, Cordia americana (L.) Gottshling & J. E. Mill., Melia azedarach L. and Parapiptadenia rigida (Benth.) Brenan, after food preference assay. Were made 20 test specimens of each species, with dimensions of 15 x 15 x 260 mm (tangential x radial x longitudinal). The physical parameters were the basic mass (ρb), the mass loss (PM), the modulus of elasticity (MOE) and rupture (MOR) from the static bending test and Janka hardness. After the test, the species with the lowest mass loss was Melia azedarach, possibly due to your extractives composition. For the species Cordia americana and Parapiptadenia rigida, about the mechanical properties, it was observed significant reduction only in the MOE of deteriorated samples compared to the control group. It's concluded that the Melia azedarach specie higher resistance it's associated with your chemical composition, and in almost all wood species there was a decrease in mechanical parameters (MOE, MOR and Janka hardness) due to attack of Nasutitermes termites.
