This review focuses on neuropeptides and peptide hormones, the largest and most diverse
class of neuroactive substances, known in Drosophila and other animals to play roles in …

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 …

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 …

Lectins constitute a complex group of proteins found in different organisms. These proteins
constitute an important field for research, as their structural diversity and affinity for several …

It has been known for more than 40 years that individual neurons can produce more than
one neurotransmitter and that neuropeptides often are colocalized with small molecule …

Neuropeptides are a diverse class of intercellular signalling molecules that mediate
neuronal regulation of many physiological and behavioural processes. Recent advances in …

Insect neuropeptides play an essential role in regulating growth, development, reproduction,
nerve conduction, metabolism, and behavior in insects; therefore, G protein-coupled …

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 …

Neuropeptides of the cockroach allatostatin (AST) family are known for their ability to inhibit
the production of juvenile hormone by the corpora allata of cockroaches. Since their …

The mannose-binding lectin from snowdrop (Galanthus nivalis agglutinin: GNA), when fed to
insects, binds to the gut epithelium and passes into the haemolymph. The potential for GNA …
