摘要

Minimum retentions of disodium octaborate tetrahydrate (DOT) needed in slashpine, Pinus elliottii Engelm. variety elliottii, wood to provide maximum protection against 2 species of subterranean termites were determined in choice and no-choice laboratory tests. Efficacy criteria for DOT were greater or equal to 90% termite mortality and equal to or less than 5% loss in weight of treated wooden blocks. For termites fed only DOT-treated wood, 0.10 and 0.30% boric acid equivalent (BAE, percentage of boric acid based on dry weight of wood, assuming all boron is present as boric acid) protected wood from the eastern subterranean termite, Reticulitermes flavipes (Kollar), and Formosan subterranean termite, Coptotermes formosanus Shiraki, respectively. When termites had a choice between treated or nontreated wooden blocks were not in contact with soil or exposed to rain, a BAE of 0.30% protected the wood from naturally occuring Reticulitermes sp. for 18 mo. In wooden structures under constant pressure from subterranean termites, concentrations greater than 0.54% BAE may be required to protect wood, especially against C. formosanus.
