. The flight behaviour of Stomoxys calcitrans (L.) in odour plumes containing carbon dioxide, acetone or l‐octen‐3‐ol was assessed from video recordings. A downwind bias was evident in clean air, whereas all three test chemicals elicited upwind anemotaxis. Response thresholds were ∼0.006% for CO2, between 0.001 and 0.01 μg/l for acetone, and ∼0.0002 u.g/1 for l‐octen‐3‐ol. Sinuosity (° cm ‐1 ) and angular velocity (° s ‐1 ) increased with C0 2 concentration, but velocity (cm s“ 1 ) decreased. Similar, but less clear effects were observed for acetone and l‐octen‐3‐ol.
