  1. Columns description. N (%) odour: number and percentage of mosquitoes that exhibited preference to the odour extract solution; N(%) control: number and percentage of mosquitoes that exhibited preference to the solvent; χ2 statistics: chi-square test comparing the proportion of mosquitoes choosing odour vs. control for each bird species; Ryan’s test: comparison of proportions of mosquitoes choosing the odour coming from different bird species (rows with the same letter indicate that proportions are not statistically different at 0.05 level).
