| description | Resistance of thermally treated woods to Nasutitermes corniger in a food preference testThe objective of this study was to evaluate the effects of thermal treatment on the resistance of Corymbia citriodora and Pinus taeda woods to the xylophagous termite Nasutitermescorniger, in a food preference test. We used temperatures of 100 °C (control), 160 °C, 180 °C, 200 °C, 220 °C, 240 °C for both wood species, and 260 °C only for Pinus taeda. Three wood planks measuring 6 cm x 16 cm x 56 cm (thickness x width x length) were thermally treated and manufactured in specimens of 10.0 cm x 2.54 cm x 0.64 cm (longitudinal x radial x tangential). Specimens were distributed in randomized blocks, with six treatments (Corymbia citriodora) and seven treatments (Pinus taeda) with 10 repetitions in a 250 liters box with 10 cm of sand; specimens were inserted in the sand, up to 1/3 of their height. The test was maintained for 45 days under laboratory conditions (25 °C ± 2 °C and 65% ± 5% relative humidity). Temperatures of 220 °C and 240 °C slightly improved the resistance of Corymbia citriodora wood to the termite. Improvements on Pinus taeda wood happened at temperatures of 240 °C and 260 °C. The temperatures of 160 °C for the eucalyptus wood and 200 °C for pinus decreased their resistance to the tested termite. |

Se probaron temperaturas de 100 °C (testigo), 160 °C, 180 °C, 200 °C, 220 °C, 240 °C, además de 260 °C para el Pinus taeda. Se sometieron al proceso de modificación térmica tres tablones de madera de 6 cm x 16 cm x 56 cm (grosor x ancho x largo), y después fueron transformados en especímenes de 10,0 cm x 2,54 cm x 0,64 cm (longitudinal x radial x tangencial). Los especímenes fueron distribuidos en bloques aleatorios, y sometidos a seis tratamientos (Corymbia citriodora) y siete tratamientos (Pinus taeda) con 10 repeticiones por tratamiento, en cajas de 250 litros con una cama de 10 cm de arena. Los especímenes de prueba se hincaron en la arena hasta 1/3 de su longitud y fueron expuestos al ataque de las termitas. El ensayo fue mantenido durante 45 días bajo condiciones del laboratorio (25 ºC ± 2 ºC y 65 % ± 5% de humedad relativa). Para la madera de Corymbia citriodora, las temperaturas de 220 °C y 240 °C mejoraron sensiblemente la resistencia a la termita. Para el Pinus taeda la mejoría ocurrió con las temperaturas de 240 °C y 260 °C. La temperatura de 160 °C para la madera de C. citriodora y la de 200 °C para el P. taeda causaron disminución en la resistencia a la termita estudiada.
