Lack of laboratory evidence for Ae. malayensis attraction to human odor. (A) Flight activity is the percentage of female mosquitoes that exited the release chamber after 20 min. (B) Attraction to human odor was estimated as the percentage of trapped mosquitoes that chose the trap with human odor, which ranges from 0% (full attraction to CO₂ without human odor) to 100% (full attraction to CO₂ with human odor). The red, vertical dashed lines indicate the expected percentage of trapped mosquitoes when there is no preference for either trap (50%). Error bars represent 95% confidence intervals of the percentages. Letters next to or above the bars indicate statistical significance. Conditions with a letter in common are not significantly different from each other. The data shown in (A) and (B) are pooled from 6 and 9 separate replicate trials of 20 to 30 females each for CO₂ only vs. CO₂ only and CO₂ + Human odor vs. CO₂ only designs, respectively, which did not differ significantly. The Ae. aegypti population was included as a positive control.
