M D Canedo, A T De Lelis

Eletropaulo (Eletricidade de Sao Paulo S/A) and IPT (Instituto de Pesquisas Tecnologicas do Estado de Sao Paulo S/A) are carrying on a study to evaluate wood species for crossarms in replacement of Aspidosperma polyneuron - Apocynaceae (Peroba-rosa) traditionally used for this purpose. Nineteen Amazon wood species were elected, with physical and mechanical properties equal or better than those presented by Peroba-rosa. Biological tests with these woods and physical tests of crossarms were carried out. Here is presented the results of the resistance test to Cryptotermes brevis attack.
