Fig. 8. Examples of hindgut muscle bioassay for R. prolixus. The first 5
min of a recording in saline applied at the open arrow, and the second 5 min
in the peptide applied at the filled arrow. (A) Rhopr/Dippu-DH31
tested at 10–10 mol l–1; (B)
Rhopr/Dippu-DH31 tested at 10–8 mol
l–1; (C) Rhopr/Dippu-DH31 tested at
10–6 mol l–1. Note the increase in frequency
and the variable change in amplitude.
