TLDR
The combined data on the primary sequence, gene expression, biosynthesis, release, interaction with the receptor and mode of action provide an accurate account of the current knowledge on how these peptides function.Abstract:
This review deals with those neuropeptidic hormones that are completely known in their primary structure together with the control processes that are linked directly or indirectly to development and reproduction. Actions are assessed for neuropeptides that regulate ecdysteroid and Juvenile Hormone production; oocyte growth or yolk deposition; and ecdysis and courtship behaviour. The combined data on the primary sequence, gene expression, biosynthesis, release, interaction with the receptor and mode of action provide an accurate account of the current knowledge on how these peptides function.read more

Body size variation in insects: a macroecological perspective
Steven L. Chown,Kevin J. Gaston +1 more
TL;DR: This review provides a critical and synthetic overview of body size variation in insects from a predominantly macroecological (large‐scale temporal and spatial) perspective and focuses on evolutionary trends, including gigantism, Cope's rule and the rates at which size change has taken place.
Unusual cardioactive peptide (CCAP) from pericardial organs of the shore crab Carcinus maenas (crustacean neuropeptide/amino acid sequence/cardioactive neurohormone/neurosecretion)
TL;DR: An unusual crustacean cardioactive peptide (CCAP) from the pericardial organs of the shore crab Carcinus maenas has been purified to homogeneity by a two-step reversed-phase HPLC procedure as discussed by the authors.

Hormonal regulation of energy metabolism in insects as a driving force for performance

TL;DR: The role of adipokinetic hormones during larval development and during molting has to be tightly regulated as well: in general, during the early phase of a larval instar intake of food prevails and the energy stores of the fat body are established, whereas, prior to the molt, insects stop feeding and mobilize energy stores in thefat body, thereby fueling energy-demanding processes such as the formation of the new cuticle and the emergence from the old one.

Pheromone biosynthesis activating neuropeptide (PBAN): regulatory role and mode of action.
TL;DR: The results raise many questions concerning the evolutionary role of the PBAN/Pyrokinin receptors belonging to the GPCR family.

An evolutionarily conserved function of the Drosophila insulin receptor and insulin-like peptides in growth control
TL;DR: This study shows that the Drosophila insulin receptor autonomously controls cell and organ size, and that overexpression of a gene encoding an insulin-like peptide is sufficient to increase body size.

A male accessory gland peptide that regulates reproductive behavior of female D. melanogaster
TL;DR: Amino acid sequencing of the purified peptide and oligonucleotide-directed cDNA cloning established that the peptide consists of 36 amino acids, and appears to be synthesized as a precursor with a hydrophobic signal sequence of 19 residues at its N-terminal end.

TL;DR: The authors plead for a concerted effort to continue research in this field, which will advance knowledge into the use of insect hormones as safer and species-specific molecules for insect pest management.

TL;DR: The recently completed Drosophila genome sequence for G protein-coupled receptors sensitive to bioactive peptides (peptide GPCRs) is scanned and 44 genes are described that represent the vast majority, and perhaps all, of the peptide G PCRs encoded in the fly genome.
