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 …

Insulin, insulin-like growth factors (IGFs) and insulin-like peptides (ILPs) are important
regulators of metabolism, growth, reproduction and lifespan, and mechanisms of insulin/IGF …

The insulin-like peptide (ILP) and insulin-like growth factor (IGF) signalling pathways play a
crucial role in the regulation of metabolism, growth and development, fecundity, stress …

Insects, like all heterotrophic organisms, acquire from their food the nutrients that are
essential for anabolic processes that lead to growth (larval stages) or reproduction (adult …

A quarter of a century has passed since bombyxin, the first insulin-like peptide identified in
insects, was discovered in the silkmoth Bombyx mori. During these years, bombyxin has …

Highlights•Insulin-like peptides (ILPs) are encoded by multiple genes in insects.•Insect ILPs
are mainly produced by the brain medial neurosecretory cells (mNSCs).•Transcription and …

Lepidoptera are unusual in possessing two distinct kinds of sperm, regular nucleated
(eupyrene) sperm and anucleate (apyrene) sperm ('parasperm'). Sperm of both types are …

Background We have developed a novel assay based on the ability of type I sucrose uptake
transporters (SUTs) to transport the fluorescent coumarin β-glucoside, esculin. Budding …

In the bivoltine strain of the silkworm, Bombyx mori, embryonic diapause is induced
transgenerationally as a maternal effect. Progeny diapause ability is determined by the …

Many insect species have several genes coding for insulin-related peptides (IRPs), but so
far only a single IRP gene has been identified in migratory locusts. Here, we report and …
