Summary
Ephestia cautella females will respond to a jet of air with an acceptance posture, and will respond more frequently when the air carries volatiles, probably male sex pheromones, from the male wings.

10 responses were recorded from each group of 10 females, every effort being directed towards stimulating individuals only once.
The angle at which the air jet impinged on a female's head was dictated by her position within the container, since the jet could be introduced only from above.
The proximal end of each male forewing had previously been sliced through to expose the bases of the scent scales normally covered by the cuticular flap.
