| description | The natural durability of the wood is an excellent characteristic for the use of wood parts under proper and efficient conditions of use. This work aimed to evaluate the natural resistance of six wood forest species to xylophagous termites in field conditions. The woods studied were Carapa guianensis Aubl, Myracrodruon urundeuva Allemão, Cedrella sp., Hymenaea courbaril L., Nectandra sp. and Manilkara elata (Allemão ex Miq.) Monach. Test samples with dimensions of 7.2 cm × 1.3 cm × 0.9 cm (longitudinal × radial × tangential) were made from each wood species. They remained exposed for 40 days under the action of Nasutitermes corniger Motschulsky termites in a food preference test, Carapa guianensis wood presented greater mass loss and susceptibility to attack by N. corniger. On the other hand, the species Cedrella sp. and Nectandra sp. showed intermediate values among the others to the analyzed aspects. The woods of Carapa guianensis, Hymenaea courbaril and Manilkara elata stood out in the grade values attributed to the wear, as well as the low susceptibility. Therefore, these latter woods are best suited for use in order to promote their efficient use, minimize damage caused by exposure to xylophagous termites and maximize the useful life and safety of the timber product. |

A durabilidade natural da madeira trata-se de excelente característica para destinar as peças de madeira em condições adequadas e eficientes de uso. Portanto, o estudo objetivou-se avaliar a resistência natural de seis espécies florestais madeireiras a cupins xilófagos em condição de campo. As madeiras estudadas das espécies tropicais foram andiroba (Carapa guianensis Aubl.), aroeira (Myracrodruon urundeuva Allemão), cedro (Cedrella sp.), jatobá (Hymenaea courbaril L.), louro canela (Nectandra sp.) e maçaranduba (Manilkara elata (Allemão ex Miq.) Monach.). De cada espécie foram produzidas amostras com dimensões de 7,2 cm × 1,3 cm × 0,9 cm (longitudinal × radial × tangencial). Essas permaneceram expostas por período de 40 dias sob a ação de cupins Nasutitermes corniger Motschulsky em ensaio de preferência alimentar, com determinação da densidade, percentual de perda de massa, índice de deterioração e o índice de susceptibilidade. A madeira de andiroba apresentou maior perda de massa e susceptibilidade ao ataque de N. corniger. Já as espécies cedro e o louro canela demonstraram valores intermediários entre as demais para os aspectos analisados. As madeiras de aroeira, jatobá e maçaranduba se destacaram nos valores de notas atribuídas ao desgaste, bem como, na baixa susceptibilidade ao ataque, tendo demonstrado maior durabilidade natural e resistência biológica ao ataque. Portanto, essas últimas madeiras são as mais indicadas para utilizações que visem promover o seu uso eficiente, a fim de minimizar os danos causados por exposição às térmitas (cupins) xilófagos e maximizar a vida útil e segurança do produto madeireiro.
