Comparison of the flight dynamics of mosquitoes around the BG-Suna and the M-Tego. Heat maps of the positional likelihood of mosquitoes flying around a the BG-Suna (from Cribellier et al. 2018) and d the M-Tego without additional host cues. The positional likelihood Pi in a cell i is defined as the normalized probability of mosquitoes to fly inside a given three-dimensional ring around the trap (average cell size = 19 × 3 mm). Random flight behaviour would result in a uniform probability equal to 1 throughout the filmed volume. Average velocity fields and streamlines of mosquitoes flying around b the BG-Suna and e the M-Tego without additional host cues. Each vector consists of the average velocity in the radial and vertical direction of all mosquitoes that flew in a cell (size = 27.5 × 27.5 mm). All velocity vectors resulting from fewer than 20 tracks were discarded. Streamlines are shown using line integral convolution (LIC). Heat maps of the average vertical acceleration of mosquitoes flying around c the BG-Suna, and f the M-Tego without additional cues
