Neuropeptides in insects act as neuromodulators in the central and peripheral nervous
system and as regulatory hormones released into the circulation. The functional roles of …

During mating, males transfer seminal proteins and peptides, along with sperm, to their
mates. In Drosophila melanogaster, seminal proteins made in the male's accessory gland …

In animals with internal fertilization, ovulation and female sperm storage are essential steps
in reproduction. While these events are often required for successful fertilization, they remain …

The search for myotropic peptide molecules in the brain, corpora cardiaca, corpora allata
suboesophageal ganglion complex of Locusta migratoria using a heterologous bioassay …

The biogenic monoamine octopamine (OA) is a crucial regulator of invertebrate physiology
and behavior. Since its discovery in the 1950s in octopus salivary glands, OA has been …

The insect ventral nerve cord consists of metamerically repeated ganglia subserving the
thoracic and abdominal segments. The abdominal ganglia control basic functions such as …

Octopamine is essential for egg-laying in Drosophila melanogaster, but the neuronal
pathways and receptors by which it regulates visceral muscles in the reproductive tract are …

The distribution, physiological role, mode of action, and pharmacology of the pentapeptide
neuroregulator proctolin are reviewed, with special emphasis on insects. Whereas proctolin …

The Dip-allatostatins are a group of 13 neuropeptides, ranging in size from 6 to 18 amino
acids, identified from a cloned cDNA sequence of Diploptera punctata. All 13 Dip …

Mating induces changes in female insects, including in egg production, ovulation and laying,
sperm storage, and behavior. Several molecules and effects that induce these changes …
