Resumo

A pesquisa objetivou analisar a eficiência do CCB-Óxido na resistência da madeira de leucena (Leucaena leucocephala) ao cupim Nasutitermes corniger, em ensaio de preferência alimentar. Foram colhidas 12 árvores com diâmetro de 6,0 a 12,0 cm, tomado a 1,30 m do solo, em Patos, Paraíba. Os troncos foram seccionados em peças de 2,0 m e descascados. Foi utilizada uma solução de 2% de ingredientes ativos de CCB-Óxido. As peças foram submersas (50 cm da base) na solução de tratamento por 3, 6, 9 e 12 dias, e determinaram-se a penetração e a retenção do produto a 50 e 100 cm da base das peças. Foram retiradas amostras de 1,5 × 1,5 × 15,0 cm entre essas posições, sendo submetidas durante 45 dias ao ataque dos cupins. O tratamento conferiu melhorias na resistência da madeira de leucena ao cupim, tendo o tempo de tratamento de 12 dias promovido proteção adequada à madeira.

Abstract

The aim of the present study was to analyze the efficiency of CCB-oxide on the resistance of Leucaena leucocephala wood to Nasutitermes corniger termite under food preference test. A total of 12 trees with diameters at breast height ranging from 6.0 to 12.0 cm were harvested in the municipality of Patos, Paraíba state, Brazil. The trunks were severed into 2.0 m parts and peeled. A solution of 2% active ingredients of CCB-oxide was used. The pieces were submerged (50 cm from the base) in the treatment solution for 3, 6, 9 and 12 days and the penetration and retention of the solution was determined at 50 and 100 cm from the base. Samples of 1.5 × 1.5 × 15.0 cm were collected between these positions and submitted to termite attack for 45 days. The treatment has improved the resistance of Leucaena leucocephala wood to xylophagous termites, and the 12-day-long treatment promoted adequate protection to the wood.

Keywords
