Fig. 4. Transepithelial voltages (Vte) expressed as percentage
of the control voltage (100%) for different concentrations of Aedae-NPF
(filled circles; control voltage 32±6 mV, N=9) and
proctolin (open diamonds; control voltage 37±5 mV,
N=6). Values are means + or
S.E.M. Asterisks indicate significant
difference from the control (P<0.05).
