Identification of PBAN-like immunoreactivity in the neuroendocrine system and midgut of Dysdercus cingulatus (Heteroptera: Pyrrhocoridae)

Polyclonal antibodies against PBAN were used to map the distribution of PBAN-like antigenic sites in the brain-suboesophageal ganglion (Br-SOG) complex, associated neurohaemal structures, ventral nerve cord ganglia and in the alimentary canal. A pair of lateral neurosecretory cells immunopositive to the antiserum were found in each half of the deutocerebrum. PBAN-like immunoreactivity (PLI) was al…
