  1. * Of total ** of total activated.
  2. Number and proportion of female Anopheles gambiae s.s. responding to stimulation (i.e. flying out of the middle chamber) and flying towards the point of stimulation (negative control and three stimuli) obtained from four replicates at four distances in the semi-field tunnel (Experiment 1). n indicates the number of mosquitoes, % indicates the proportion of mosquitoes.
