Abstract: A field test with 1‐octen‐3‐ol (octenol) used as an attractant in flight traps was carried out in subarctic Norway (69 o 40′N, 23 o 30′E) during four warm days in July 1993. Aedes spp. (Dipt., Culicidae) were caught in significantly (P = 0.0001) higher numbers in octenol‐baited traps than in empty control traps (approximately seven‐fold increase), as was Hybomitra lundbecki Lyneborg (Dipt., Tabanidae), (P = 0.0003) (approximately nine‐fold increase). Octenol also increased but not significantly (P = 0.09, n = 14) the catch of Chrysops relictus Meigen (Dipt., Tabanidae). The study confirmed the established role of octenol as an attractant of biting Diptera. The advantage of using octenol instead of, or in combination with, carbon dioxide in control or surveillance of such insects is discussed.
