Effects of air or air containing CO2 on mosquito attraction. Trap captures of 1- to 3-day-old female A. aegypti and 1- to 3-day-old female C. pipiens in response to medical-grade air (air), or medical-grade air containing 1% CO2 (air & CO2). In each experiment, an asterisk indicates a significant preference (P < 0.05) for the specific test stimulus (binary logistic regression analyses with logit link function); different letters on paired bars in parallel experiments indicate a difference in the mean proportion of mosquitoes responding to respective stimuli (P < 0.05). Numbers within bars indicate the mean percentage of mosquitoes not captured (=non-responders); this percentage is relatively high here because experiments 17–20 were run for only 2 h, instead of 24 h (experiments 1–16).
