(A) Free dopamine (DA) and (B) dopamine conjugates (DA-X) quantified in salivary glands (SG), synganglia (SYN) and haemolymph (HL) of five day-fed female I. scapularis ticks. Samples are from the ticks that were stimulated by pilocarpine (experimental group) or Hank's buffer solution (control group) for 0.5 hours or 4 hours. (C) Proportions of DA and DA-X. Data were from three biological replicates are presented as means with standard deviation (S.D.). Note that DA-X includes dopamine sulphate (DA-S) in this experimental set.
