Short-term experiment showing Trypanosoma rangeli numbers in the gut of Rhodnius prolixus. Parasite numbers in R. prolixus 5^th instar nymphs were analysed in anterior midgut and posterior midgut plus rectum at different days after feeding. The insects were fed on inactivated blood containing 1 × 10⁶ epimastigotes/mL  T. rangeli Macias strain. Bars represent mean ± SEM of three independent experiments each with five insects (n=15). Means were compared using one-way ANOVA and Kruskal-Wallis test; ***p < 0.001 and *p < 0.05.
