Table 1 The experimental array of combinations of the three biophysical aspects: i) the availability of one (no-choice) or two (choice) odor sources. ii) the flow condition: either Undisturbed- no cylinder is placed in the wind tunnel, or disturbed- a cylinder is placed 0.2 m upwind of the odor source (see Fig. 1A)

  1. An odor source placed directly downwind of the vertical cylinder was termed ‘Aligned’. In choice conditions under disturbed flow, the neighbor odor source placed offset from the vertical cylinder was defined as ‘Offset’. iii) the Odor source, with either High—fed females and Low—starved females. The experimental array included 9 treatments (T1-9) with a total of 14 combinations (i.e., 14 options): each of the no-choice treatments (T1-4) had one option, and each of the choice treatments (T5-9) included two options). Bold numbers represent the number of each treatment
