. Action potentials from olfactory cells in antennae (funiculi) of living tsetse flies, Glossina morsitans morsitans Westwood, were recorded using a surface‐contact technique. Stimuli were the vapours of the seven alkylphenols identified in cattle urine: phenol, 3‐methyl‐, 3‐ethyl‐, 3‐ n ‐propyl‐, 4‐methyl‐, 4‐ethyl‐, and 4‐ n ‐propylphenol. In addition, responses to the vapours of 1‐octen‐3‐ol, acetone and dichloromethane were recorded. The phenol‐sensitive cells could be grouped into four subclasses. Subclass, 1, 2 and 3 cells responded to the phenols only, cells of subclass 1 and 2 being activated by these substances, those of subclass 3 inhibited. Cells of subclass 4 were activated to a similar degree by all phenols and by one or more of the other chemicals tested. Subclass 1 cells were strongly activated by the 3‐alkylphenols, whereas subclass 2 cells were most sensitive to 4‐methylphenol. Subclass 3 cells were most strongly inhibited by phenol, and 3‐ and 4‐methylphenol. The results suggest that though individual phenols may be attractive to G. m. morsitans , preference for certain blends of phenols may exist; for example, blends composed of moderate doses of 4‐methylphenol and 3‐methyl‐, 3‐ethyl‐ or 3‐ n ‐propylphenol.
