The research evaluated the efficiency of Eremanthus erythropappus (DC.) Macleish. oil to improve the resistance ofCeiba pentandra (L.) Gaertn. wood to Nasutitermes corniger Motsch. termite under laboratory condition. Wood samples with nominaldimensions of 0.7 x 2.0 x 2.5 cm (thickness x width x length), forcedfeeding assay and of 0.7 x 2.0 x 10.2 cm (thickness x width x length), alimentary preference assay were treated by cold immersion process and reached medium retentions of 10.61; 16.73; 22.04; and26.94 kg of oil/m3 of wood (force feeding) and of 38.35; 58.22; 87.53; e 108.36 kg of oil/m3 of wood (preference feeding) and submittedto Nasutitermes corniger termite attack during 28 (force feeding) and 20 days (alimentary preference). The results showed that theEremanthus erythropappus oil in the retentions of 10.61 kg/m3 (forced feeding) and 38.35 kg/m3 (preference feeding) inhibited theattack and in the retentions of 16.73 kg/m3 (force feeding) and of 58.22 kg/m3 (preference feeding) prevented the attack in woodsamples, making unfeasible the access of the termites to the food source. |
