Natural Resistance of Eucalyptus urophylla and Corymbia citriodora to Coptotermes gestroi (Isoptera; Rhinotermitidae)

ABSTRACT

This work aimed to evaluate the natural resistance of Eucalyptus urophylla and Corymbia citriodora to Coptotermes gestroi attacks. The termites’ resistance evaluation was performed according to the ASTM D - 3345 (American..., 1994American Society for Testing and Materials - ASTM. ASTM D-3345. Standard test method for laboratory evaluation of wood and other cellulosic materials for resistance to termites. ASTM Standards; 1994. vol. 0410, p.119-21. Annual book.) standard. The average weight loss of Pinus elliottii was greater than that of Eucalyptus urophylla and Corymbia citriodora; this indicates that Pinus elliottii has a greater susceptibility to Coptotermes gestroi attacks. The mortality of termites showed that E. urophylla and C. citriodora wood is less attractive and more resistant to degradation by Coptotermes gestroi, while P. elliottii is more vulnerable to attacks.
