Table 10 Volumes of sugar solution ingested by Lutzomyia longipalpis after 2 days of exposition to sugar diets containing red dye. Insects were fed on sucrose only (control) or sucrose plus mandelonitrile. The amounts of sugar solution ingested were obtained from a standard curve performed with the red dye and subsequent calculations. The values are mean and SEM in ηl/insect obtained from 18 to 21 samples (individual measurements)
