discusses recent findings. Over 200 articles were published in scientific journals on various …

The biological concept of stress originated in mammals, where a “General Adaptation
Syndrome” describes a set of common integrated physiological responses to diverse …

Insect ecdysis sequence is composed of pre-ecdysis, ecdysis and post-ecdysis behaviors
controlled by a complex cascade of peptide hormones from endocrine Inka cells and …

Many behavioral and physiological processes in adult insects are influenced by both the
endocrine and circadian systems, suggesting that these two key physiological systems …

The undecapeptide corazonin, initially discovered from the American cockroach as a strong
cardioaccelerator, is now known to be ubiquitously present in arthropods, although it is …

Monocrotaline (MCT) is a toxic pyrrolizidine alkaloid found in plants of the Crotalaria genus.
As primary pollinators of Crotalaria plants, honeybees come into contact with this harmful …

Corazonin (Crz) is an 11 amino acid C-terminally amidated neuropeptide that has been
identified in most arthropods examined with the notable exception of beetles and an aphid …

Corazonin is a peptidergic neurohormone of insects that is expressed in neurosecretory
neurons of the pars lateralis of the protocerebrum and transported via nervi corporis cardiaci …

Phase polyphenism is an adaptive phenomenon in which some traits vary continuously in
response to population densities. In locusts, two extreme phases, solitarious and gregarious …

Although the corazonin gene (Crz) has been molecularly characterized, little is known
concerning the function of this neuropeptide in Drosophila melanogaster. To gain insight …
