Fig. 6. Pattern of crustacean cardioactive peptide (CCAP) immunoreactivity in the
frontal ganglion of locusts dissected at three out of four different stages
tested: I, mid last larval instar; III, air-swallowing; IV, late ecdysis. (A)
Immunoreactive axons that innervate the frontal ganglion (FG) neuropil. (B)
CCAP-immunoreactive area in the ganglion neuropil. (C) Graphic representation
of the CCAP-immunoreactive neuropil area (mean ± s.d. N=6;
*P<0.05; **P<0.01).
