Changes in Na⁺ transport across female rectal pad epithelia in response to saline (vehicle control), Droso-leucokinin and AedaeCAPA-PK1. Experiments were run only using hindgut preparations that were initially exhibiting hemolymph-directed ion flux (absorption) when unstimulated. Mean ± SEM obtained from 10 to 14 tissue preparations. There was a significant reduction in Na⁺ absorption in response to Droso-leucokinin (p < 0.05); however, ion transport did not significantly change following AedaeCAPA-PK1 treatment in comparison to basal transport activity (A), determined by a one-way ANOVA and Tukey’s post hoc test. Still images of the dissected rectum are demonstrated with ion flux recordings obtained from a sample measurement during baseline activity in saline (B,D) followed by either Droso-leucokinin (C) or AedaeCAPA-PK1 (E) application. Arrows indicate the direction and approximate the magnitude of Na⁺ transport, but are not drawn to scale. Scale bars, 100 μm.
