In this research, weaimed to evaluate the natural resistance of ten forest wood species used in joinery to the attack of dry-wood termite Cryptotermes brevis in laboratory test. The wood species studied were amoreira (Chlorophora tinctoria), angelim-pedra (Hymenolobium petraeum), Anadenanthera columbrina var. cebil (angico-vermelho), Anadenanthera peregrina (angico-verdadeiro), Dalbergia nigra (jacaranda-da-bahia), Manilkara longifolia (paraju), Peltogine nitens (roxinho), Caesalpinia echinata (pau-brasil), Eucalyptus cloeziana and Eucalyptus torelliana. The woods studied were susceptible to C. brevisattack, except for A. columbrina and M. longifolia woods. H. petraeum, D. nigra and C. echinata woods showed lowermortality compared to other species.The highest levels of wood waste were observed in D. nigra, H. petraeum, C. echinata and E. cloeziana woods. C. tinctoria, P. nitens and E. torelliana woods presented superficial waste. Higher values oftermite mortality were observed in woods of greater density, and higher levels of extractives and ash. However, there is not one sole characteristic that could beused to relate the attackof termites to the woods studied.
