The orientation behaviour of male tropical warehouse moths, Ephestia cautella (Walker) (Lepidoptera: Phycitidae) was observed in a flight tunnel in response to synthetic pheromone components. A blend of 2:1 (Z, E)9, 12–14: Ac (ZETA) and (Z)9–14:Ac (ZTA) equivalent to that released by virgin female moths caused more moths to fly upwind, alight at the lure and display hairpencils than ZETA alone. No response was obtained from the minor component ZTA alone, but the addition of (Z, E)9, 12–14:OH (ZETOH) to a ZETA + ZTA blend inhibited upwind flight by male moths. Analysis of the flight tracks of male moths in ZETA + ZTA and ZETA plumes showed that the moths flew faster and straighter towards the ZETA + ZTA source by decreasing the track reversal distance and track angle. The numbers of moths caught on sticky traps with ZETA were increased by the addition of ZTA.
