There are two main classes of hormones in insects: 1) the true hormones produced by
epithelial glands and belonging to the ecdysteroids or juvenile hormones and 2) the …

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 …

Concurrent with our expanding knowledge of the general field of endocrinology has come
the revelation that what was accepted as a central dogma is no longer true. In the case of …

This review focuses on the state of the art on neuropeptide receptors in insects. Most of
these receptors are G protein-coupled receptors (GPCRs) and are involved in the regulation …

Allatostatins are pleiotropic neuropeptides for which one function in insects is the inhibition
of juvenile hormone synthesis. Juvenile hormone, an important regulator of development …

Four nonapeptides that inhibit juvenile hormone synthesis have been isolated by four high
performance liquid chromatographic steps from extracts of the brain of the field cricket …

Insects form the largest class of the phylum Arthropoda. There are at least one million known
species, so more than 50% of all existing organisms on earth are insects. It is even thought …

The distribution and morphology of neurons containing allatostatin‐related substances in
the brain of the locust Schistocerca gregaria was investigated using an antiserum against …

The high degree of conservation of the core sequence of the “cockroach‐types” of AST and
their widespread distribution suggest that they should be considered a ubiquitous family of …
