Frequency of decision for sample or control of naïve L. heterotoma males in a y-tube experiment when choosing between the odour of 1/5 to 1/80 female equivalent of virgin L. heterotoma female extract and the control. Bar colours indicate female extract (blue) and control (brown). P-values (rounded to third decimal) are given for the two-sided binomial test. For each experiment n=30.
