Figure 1

Aedes aegypti responds to human odour sex- and age-dependently, reflected in overall antennal transcript abundance. (A) Diagram of the Y-tube olfactometer used to assess the behavioural preference of male and female mosquitoes to human odour. (B) Behavioural analysis of females and males, scored as preference indices, revealed both sex- and age-dependent responses to human odour. Age is defined as the number of days post-emergence. Error bars represent standard error. (C) A principal component analysis representing the overall transcript abundance in the antennae of female and male Ae. aegypti, at 1, 3 and 5 days post-emergence (dpe). The two major principal components explain for 45.2% of the variance for the six biological replicates of each sex and age, as indicated by different colours.
