Abstract
A peptidomics approach was applied to determine the peptides in the larval central nervous system of the grey flesh fly, Neo-bellieria bullata. Fractions obtained by high performance liquid chromatography were analysed by MALDI-TOF and ESI-Q-TOF mass spectrometry. This provided biochemical evidence for the presence of 18 neuropeptides, 11 of which were novel Neobellieria peptides. Most prominently present were the FMRFamide-related peptides: 7 FNIRFamides, 1 FIRFamide, and Neb-myosuppressin. The three putative capa-gene products Neb-pyrokinin and the periviscerokinins Neb-PVK-1 and -2 were detected, as well as another pyrokinin. This Neb-PK-2 was also present in the ring gland along with corazonin, Neb-myosuppressin, and Neb-AKH-GK, an intermediate processing product of the adipokinetic hormone. Furthermore, the central nervous system contained Neb-LFamide, proctolin, and FDFHTVamide, designated as Neb-TVamide. With this study, we considerably increased our knowledge of the neuropeptidome of the pest fly N. bullata, which is an important insect model for physiological research. (C) 2004 Elsevier Inc.
