Table 3 Statistical comparisons of the effects of odour and appearance of an object on mean flight parameters. (A) Female mosquitoes with black tile present, in clean air vs host odour (Fig. 6a, b). (B) Female mosquitoes in host odour with black vs clear tile present (Fig. 6b, c). 3D positional data were aligned to the time at which a track came nearest the tile (0.0 s) and statistical comparisons correspond to the maximal reading for the particular metric tested (at -0.5, 0.1 and 0.5 s for speed and velocities, and at -0.5, 0.04 and 0.5 s for angular velocity, significant results in bold). All values were calculated using the t-test for unequal variance

From: Seeing is believing: the nocturnal malarial mosquito Anopheles coluzzii responds to visual host-cues when odour indicates a host is nearby
