The research aimed to evaluate the effectiveness of CCB preservative in improving the resistance of two bamboo species (Bambusa vulgaris and Dendrocalamus giganteus) the action of termites and xylophagous beetles. The bamboo stems collected in the vicinity of Alegre and Jeronimo Monteiro, towns of southern Espirito Santo state, Brazil, were transformed into culms of 2.0 m long and treated in a solution of 1 or 3% active ingredient (a.i.) of the commercial product “MOQ OX 50”, based on copper, chromium and boron (CCB). The treatment methods used were the sap displacement (intact and ruptured diaphragm), long-term immersion and Boucherie modified. In the methods by sap displacement and the long-term immersion the stems were exposed in solutions for periods of 5, 10 or 15 days, and in Boucherie’s modified method of treatment there was no segregation between treatment times. To assess the efficiency of the methods, test samples were taken at the position of 50 cm from the base of the stems. In the tests, the termite species Nasutitermes corniger and the beetle Dinoderus minutus were used. Based on the analysis of the results obtained, it was found that the two species of bamboo treated showed high resistance to attack by termites and beetles, and including untreated samples showed low mass loss when subjected to the tests.
