Influence of different adhesive utilized for manufacture of particleboards, under activity by Coptotermes gestroi (Wasmann, 1896) (Isoptera: Rhinotermitidae).

Abstract

The objective of this work was to study the resistance of particleboards under activity by Coptotermes gestroi (WASMANN, 1896). The particleboards were made with particles originating from Pinus caribaea var. caribaea, using tannin resin, produced from tannin of Eucalyptus pellita and Acacia mearnsii (De Wild). The methodology used consists on attracting termites to masonry camera, without interfering in the colony, using cardboard as bait. Samples of 5,0 x 2,5 x 1,27cm were exposed to the attack of the same ones for ninety days. After that period, evaluations were accomplished for verification the performance of them on the samples. It was verified that the samples which contained fenol-formaldeído, be came more resistant to the action of the termite and the ones that contained tannin of Acacia mearnsii, or tannin of Acacia mearnsii and Eucalyptus pellita, are less resistant to the action of these termite.
