Tratamentos não industriais em madeiras de Eucalyptus urophylla S.T.Blake

Abstract

The efficiency of different non-industrial treatments in the wood preservation of two Eucalyptus urophylla clones against termite attack was evaluated. The specimens were submitted to the following treatments: surface carbonization, brushing, hot-cold bath and prolonged immersion in CCB solution. They were then exposed for 45 days to a colony of termites of the Nasutitermes genus in alimentary preference assay. The loss of mass and retention of each treatment in both clones were determined. The treatment of wood increased the resistance to attack of termite, especially the methods of prolonged immersion and hot-cold bath, recommending them for the preservation of woods that have contact with the ground.
