“…PBAN is produced in three discrete sets of neurosecretory cells in the subesophageal ganglion of adult ECB females (Ma and Roelofs, 1995a, c). The subesophageal ganglion establishes a physical connection between the brain and the ventral nervous system (Ma and Roelofs, 1995a), and it had been suggested that, in some species, PBAN could be transported via the ventral nerve cord to its target site (Teal et al, 1989). However, surgical section of the ventral nerve cord in ECB females does not lead to a decrease in pheromone production, nor does a complete removal of the nerve cord.…”

The European corn borer Ostrinia nubilalis (ECB; Lepidoptera: Crambidae) is a widely recognized pest of agricultural significance over much of the northern hemisphere. Because of the potential value of pheromone-based control, there has been considerable effort devoted to elucidation of the ECB chemical ecology. The species is polymorphic regarding its female-produced pheromone. Partly because of this feature, over the years the ECB has become a model to study pheromone evolution. This review should assist in identifying new areas of pheromone research by providing an overview of the literature produced on this subject for the ECB since the late 1960's.

“…In ECB moths, previous research has detected PBAN‐like biological activity and immunoreactivity in three sets of neurosecretory cells of the SG and in the corpora cardiaca (Ma & Roelofs, ). These observations, along with in vitro experiments employing synthetic Bommo‐PBAN and isolated PGs, have indicated that PBAN‐related neuropeptides in Os.…”

Pheromone biosynthesis activating neuropeptide (PBAN) is a member of the pyrokinin (FXPRLamide) insect neuropeptides. Here, we report the cloning of the gene Ostnu-PBAN from the E and Z pheromone strains of the European corn borer (ECB), Ostrinia nubilalis (Lepidoptera: Crambidae), a major pest of maize. The Ostnu-PBAN genomic sequence is > 5 kb in length and consists of six exons. The deduced amino acid sequence revealed a 200-residue precursor protein including a signal peptide, a 24-amino acid (aa) diapause hormone, a 37-aa PBAN and three other FXPRLamide neuropeptides. Our in vivo assays suggest that the 37-aa synthetic Ostnu-PBAN is hormonally active in the pheromone gland. It restores sex pheromone production to normal levels in mated females and decapitated virgins of both E and Z cultures. The results of a real-time PCR analysis indicated that Ostnu-PBAN mRNA levels reached a plateau in the brain-suboesophageal ganglion complexes 1 day after eclosion, and mating did not affect the mRNA expression. Three size classes of Ostnu-PBAN mRNA (1.9, 2.0 and 2.1 kb) were obtained, differing only in the length of the 3' untranslated region. However, there was no correlation between sequence divergence and the pheromone composition, voltinism or geographical origin (Hungary, Slovenia, Sweden, Turkey) of ECB moths.

“…Although In situ staining was faster and less time consuming, but only the position of surficial NSCs were displayed and the other properties of NSCs could not be characterized. Ma and Roelofs (1995) applied both in situ and section staining to study NSCs in European corn borer moth, Ostrinia nubilalis. Based on their results, of the three histologically revealed groups, only one group could be revealed by in situ staining.…”

Nerve cord configuration and brain neurosecretory cell (NSC) characteristics were studied in adult firefly, Luciola gorhami, applying two methods, in situ and section staining. Nerve cord was of primitive type and consisted of brain, subesophageal ganglion, three thoracic and seven abdominal ganglia which were connected to each other serially through a pair of longitudinal connectives. Thoracic ganglia were separated and had the same size. All abdominal ganglia had the same size except the last one which was twice larger than the others. Abdominal ganglia were not fused with thoracic ganglia. Using in situ staining, 26 neurosecretory cells (NSCs) stained as median neurosecretory cells (MNSCs) and lateral neurosecretory cells (LNSCs). MNSCs consisted of 20 cells in three groups in pars intercerebralis. MNSCs had a U shaped arrangement in such a way that 4 round and large cells were located in front and two parallel groups (8 pryiform to round cells in each group) located in back. LNSCs were comprised of 6 large cells in two groups (one group on each lateral lobe of protocerebrum). MNSCs pathways were not clear but LNSCs pathways were clear and ipsilateral. Using section staining, large number of NSCs in pars intercerebralis stained gray and purple in color. Gray cells were large, more in number and appeared in many sections. Purple cells were large and grouped in the middle of gray cells. Both types of cells were on the surface area of brain and had large nucleus. Their axons were bundled together and extended backwards to the rear of brain.
