ABSTRACT
The resistance of Myracrodruon urundeuva, Senna siamea and Tabebuia impetiginosa woods to fungi and termites was evaluated, under laboratory condition. Samples measuring 2.54 x 2.00 x 1.00 cm (fungi) and 2.54 x 2.00 x 0.64 cm (termites) were obtained from four positions in pith to bark direction and exposed to action of Postia placenta and Neolentinus lepideus fungi and Nasutitermes corniger termites. The wood natural resistance to xylophages was not affected by wood specific gravity or by content of extracted substance in hot water. The heartwood of M. urundeuva was more resistant than sapwood among the tested woods.
