Neuropeptides and neuropeptide receptors are crucial regulators for the behavior, lifecycle,
and physiology of insects and are mainly produced and released from the neurosecretory …

The sugar beet moth, Scrobipalpa ocellatella (Boyd), one of the most severe sugar beet
pests, causes quantitative and qualitative yield losses late in the autumn. Previously, it was …

Diapause, a programmed developmental arrest, is common in insects, enabling them to
survive adverse seasons. It is well established that pupal diapause is regulated by …

The evolution of insect sociality has repeatedly involved changes in developmental events
and their timing. Here, we propose the hypothesis that loss of a canonical regulator of …

In this study, we identified ecdysteroidogenic enzymes in the cabbage armyworm, Mamestra
brassicae, and demonstrated reduced expression of these genes during diapause. Some …

Many insects undergo diapause to survive adverse seasons. Although the mechanism of
diapause induction is the subject of extensive study, that of diapause termination remains …

The prothoracicotropic hormone (PTTH) is one of the earliest hormones ever discovered in
insects. Mature PTTH is a homodimer of~ 100 amino acid residue peptides linked by an …

The sugar beet moth, Scrobipalpa ocellatella (Boyd), one of the most severe sugar beet
pests, causes quantitative and qualitative yield losses late in the autumn. Previously, it was …

This chapter reviews the endocrine mechanisms regulating insect diapause, especially
pupal diapause and deals with how pupal diapause is regulated by hormones. The oldest …
