Fig. 9. Pymetrozine was not observed to have effects on the campaniform sensillae
of the dorsal tibia (A), the wing hinge stretch receptor (B), the campaniform
sensillae on the subcosta vein (C) or the hair sensillae on the tegula (D).
Data before (top traces) and after (middle traces) pymetrozine application
(10–6 mol l–1) are shown for comparison;
stimulus application is shown in the lower traces [pressure on sensillae in A,
upward movement of the wing in B, pressure on the subcosta vein in C (note
that stimulus duration outlasted length of sample trace for lower recording),
stroking of tegula hairs in D (only stimulus onset shown here due to variable
stimulus durations)]. (i) Sample recordings; (ii) time histograms. Ordinates
of histograms normalised to number of stimulus presentations, bin widths 25 ms
in A, 10 ms in B and D, 5 ms in C. Note that in A the campaniform sensillae
respond strongly to the onset of cuticular pressure but just slightly to
maintained pressure and to termination of cuticle indentation. Arrow in B
indicates response of wing chordotonal organ sensillae to the stimulus.
