Fig. 5. Average change in track angle over time when flying in (right; mosquitoes entering the plume) or out (left; mosquitoes leaving the plume) of a plume consisting of skin odour or CO₂. Straight upwind flight would be 0°. The grey vertical line represents the plume boundary. Values are means ± S.E.M., averaged over all mosquito tracks (see N values) (A) Skin odour series: 100% skin odour (N=36), 20% skin odour (N=28), 4% skin odour (N=22), `hand' (N=49), clean air (N=17); (B) CO₂ series: 1% CO₂ (N=31), 0.3% CO₂ (N=26), 0.1% CO₂ (N=30), 0.05% CO₂ (N=25), `hand' (N=23); (C) sensitization series: 100% skin odour (N=24), 20% skin odour (N=38), 20% skin odour + CO₂ (N=40), CO₂ (N=19).
