Durability of uranine marking. The proportion of female and male An. gambiae (mean of three treatment and four control cage samples ± SEM) identified as ‘marked’ by feeding with increasing concentrations of uranine and evaluated for 3 weeks post-marking. Doses of 0.2% and below were not distinguishable from natural auto-fluorescence (p > 0.05), males were more rapidly identified as marked than females (p < 0.001), higher doses are more rapidly identified and last longer (p < 0.05). The number analysed for each of the 3 weeks is shown in parentheses below the X axis
