Resumo

O objetivo da pesquisa foi avaliar a eficiência do preservativo CCB na melhoria da resistência de duas espécies de bambu ( Bambusa vulgaris check for this species in other resources e Dendrocalamus giganteus check for this species in other resources ) à ação de cupins e coleópteros xilófagos. As hastes de bambu coletadas nas proximidades dos municípios de Alegre e Jerônimo Monteiro, sul do Espírito Santo, foram transformadas em colmos de 2,0 m de comprimento e tratadas em solução de 1 ou 3% de ingredientes ativos (i.a.) do produto comercial “MOQ OX 50”, à base de cobre, cromo e boro (CCB). Os métodos de tratamento empregados foram os de transpiração radial (diafragma integro e rompido), imersão prolongada e Boucherie modificado. Nos métodos por transpiração radial e imersão prolongada, os colmos foram expostos nas soluções por períodos de 5, 10 ou 15 dias, já no método de Boucherie modificado não houve segregação entre os tempos de tratamento. Para avaliar a eficiência dos métodos, foram retiradas amostras na posição a 50 cm da base dos colmos. Nos ensaios foram utilizados térmitas da espécie Nasutitermes corniger check for this species in other resources e o coleóptero Dinoderus minutus check for this species in other resources . A partir das análises dos resultados obtidos, foi verificado que, as duas espécies de bambu tratadas apresentaram alta resistência ao ataque dos cupins e coleópteros, e inclusive as amostras não tratadas apresentaram baixa perda de massa quando submetidas aos ensaios.

Abstract

The research aimed to evaluate the effectiveness of CCB preservative in improving the resistance of two bamboo species ( Bambusa vulgaris check for this species in other resources and Dendrocalamus giganteus check for this species in other resources ) the action of termites and xylophagous beetles. The bamboo stems collected in the vicinity of Alegre and Jerônimo Monteiro, towns of southern Espírito 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 check for this species in other resources and the beetle Dinoderus minutus check for this species in other resources 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.
