Figure 4

Sensitivity of ALNs from Bombus terrestris and Apis mellifera to tetramethrin. (A,B) Use-dependent decrease in the sodium peak current amplitude in control condition (left) and with tetramethrin 10 µM (right; *p < 0.05; **p < 0.01; ***p < 0.005). Scales on Y axis are identical. (C) Mean percentages of modified voltage-gated sodium channels in tetramethrin-exposed ALNs (*p < 0.05). (D) Decay of the tetramethrin-induced tail current after ten consecutive depolarizations. The decay of the tail current is represented by the parameter R600 which is the percentage of the tail current that remains 600 ms after the end of the tenth depolarization. Tetramethrin-induced tail current decayed faster with Am ALNs than with their Bt counterparts (**p < 0.005).
