Effect of HsTRPA inhibitors on sucrose responsiveness. Different groups of bees were injected with Ringer as control (A) or with a HsTRPA inhibitor, either (B) menthol (5 mM) or (C) Ruthenium red (RuR, 1 mM). Proboscis extension responses (PER) were measured in response to sucrose solutions at increasing concentrations (blue) alternated with water controls (white). (D) Comparison of sucrose response curves among the three groups (Ringer: gray circles; menthol: light blue triangles; RuR: orange squares). Inhibitor injections did not impact sucrose responsiveness (NS: Non Significant; ***p < 0.001).
