Fig. 10. The chordotonal organs associated with the wing hinge stretch receptor (A) and the tegula (B) are affected by pymetrozine like the femoral chordotonal organ (fCO). Data before (top traces) and after (middle traces) pymetrozine application (10^–6 mol l^–1) are shown for comparison; stimulus (lower trace in A; downward movement of wing); arrows in B (onset of pressure on tegula base). (i) Sample recordings; (ii) time histograms. Ordinates of histograms normalised to number of stimulus presentations, bin widths 10 ms.
