Abstract
Foragers of the Formosan subterranean termite, Coptotermes formosanus Shiraki, were allowed to tunnel in two dimensional, sand filled arenas containing Douglas-fir (Pseudotsuga menziesii [Mirb.] Franco) wafers pressure treated with disodium octaborate tetrahydrate (DOT) to an average retention of 1.77% BAE on one side of each arena, and untreated wafers of Douglas-fir on the other side. Arenas were established both in the laboratory and in the field. Initial tunnel formation was unaffected by the presence of borate-treated wood. Avoidance of borate-treated wood developed after ca. 3–5 days. Termites did not avoid borate-treated wood as a result of necrophobic behavior. Termite responses when the locations of the treated and untreated wafers were switched within the arenas indicated that the delayed avoidance was related to the location of the treated wood rather than to recognition of the chemical treatment.
