This research aimed at evaluating the natural resistance of seven woods to xylophogous fungi and subterranean termites under laboratory assay. The studied woods were Leucaena leucocephala, Cordia trichotoma, Mimosa tenuiflora, Croton sonderianus, Mimosa caesalpiniifolia, Azadirachta indica and Tectona grandis. Test samples measuring 2.54 x 2.00 x 1.00 cm (fungi) and 2.54 x 2.00 x 0.64 cm (termites), with larger dimensions in fiber direction were obtained in four positions in pith-to-bark direction. The samples were submitted by 98 days to action of Postia placenta and Polyporus fumosus fungi or 28 days to the termite Nasutitermes corniger action. To fungi, the Mimosa tenuiflora and Mimosa caesalpiniifolia woods were the more resistant and those of Azadirachta indica and Croton sonderianus the less resistant. The fungus Postia placenta attacked more severely the tested woods. To termites, the Mimosa tenuiflora, Cordia trichotoma, and Mimosa caesalpiniifolia were the most resistant and the Leucaena leucocephala the less resistant. The coming wood of external section of log were the more attacked. To fungi, there was an inverse relationship between the density and the loss of mass. Already for the termites, there was not relationship between the resistance and the density of the wood. |
