Tests of the general null hypothesis that there is no difference between A) the activation response of A. arabiensis mosquitoes and B) the attraction response to each stimulus and to the controls at each distance tested in the open field experiment (Experiment 2), performed using the best-fitting model. Comparisons highlighted in bold are statistically significant at the α = 0.05 level.
