Figure 7.

Effect of HsTRPA inhibitors on thermal responsiveness. Different groups of bees were injected with Ringer as control (A) or with an HsTRPA inhibitor, either menthol (5 mM; B) or ruthenium red (RuR, 1 mM; C) SER was measured in response to increasing temperatures (red) alternated with tactile controls (white). (D) Comparison of thermal response curves among the three groups (Ringer: gray circles; menthol: light blue triangles; RuR: orange squares). Both inhibitors decreased heat responsiveness (^*p < 0.05; ^***p < 0.001).
