Response of Anopheles coluzzii mosquitoes to different concentrations of human odorants. a Kaplan–Meier estimate shows the proportion of mosquitoes that remained on the cage wall over time in response to test odorants and the paraffin oil control (n = 30 mosquitos). Asterisks indicate significant differences from paraffin oil (Cox Proportional Hazard Model, ***P < 0.001). b (left, top) A schematic of the calcium imaging setup. (left, bottom) Example heatmap from calcium imaging recording shows the response to paraffin oil (control). (right) Example heatmaps from calcium imaging recordings show the responses to 1-octen-3-ol and benzaldehyde at 0.1, 1, 10, and 100% concentrations. Red arrowheads point to neurons that start responding at higher odorant concentrations, and orange arrowheads point to neurons that showed stronger responses at higher concentrations
