Effects of blood-feeding on the locomotor activity of Aedes aegypti (A) and Aedes albopictus (B). Locomotor activity of virgin/unfed (black line; n = 32 for Ae. aegypti and n = 28 for Ae. albopictus) and of virgin/blood-fed (red line) Ae. aegypti females (A; n = 29) and (blue line) Ae. albopictus females (B; n = 28) exposed to two days of LD 12:12, at 25°C. First and second days represent, respectively, 24 and 48 hours after blood-feeding. White column represents the photophase and grey column the scothophase. Some reading time points exceeding the scale are indicated with letters, and their values are as follows: a = 19.66 (+6.15); b = 16.93 (+3.77); c = 18.72 (+3.86).
