Abstract:

Forty-six local and imported wood were tested for resistance to feeding damage by the termite Anacanthotermes ochraceus (Burmeister), the most dominant species in the United Arab Emirates and the Arab Gulf region. Wood was used for construction, wall paneling, and furniture. Wood was evaluated in a 4-wk forced feeding bioassay. Each wood block was graded by the amount of termite damage by using a damage rating index (DRI) of 0 to 5 and wood rating index from very resistant to very susceptible wood. Local wood was mostly susceptible to feeding of termites; imported wood varied in resistance to feeding damage. Wood was placed in groups according to the percentages of weight loss (WL), termite survival (TS), and DRI. Wood was classified as very resistant (%WL from 0.0 to 0.3, %TS from 0.01 to 0.5, and DRI of 0.01), resistant (%WL from 1.1 to 4.9, %TS from 0.8 to 4.8, and DRI of 1.0), moderately resistant (%WL from 6.6 to 9.3, %TS from 6.3 to 8.3, and DRI of 2.0–2.3), slightly resistant (%WL from 10.1 to 19.9, %TS from 9.5 to 28.0, and DRI of 2.5–3.5), susceptible (%WL from 21.5 to 48.6, %TS from 37.3 to 64.8, and DRI of 4.0–4.3) and very susceptible (%WL from 50.0 to 59.8, %TS from 72.8 to 79.0, and DRI of 4.5–5.0). The characterization of the extracts of resistant wood may prove of economic value and lead to the development of new chemicals (repellents or antifeedants) for termite control.
