Peptides, 1985
Peptides with adipokinetic (and usually carbohydrate-mobilizing) potency have been demonstrated in various insects, including Locusta migratoria, Schistocerca gregaria, Manduca sexta, Danaus plexippus and Periplaneta americana. As far as characterized by now the adipokinetic factors are blocked peptides, consisting of eight to ten amino acid residues ...

Hormones Controlling Insect Metamorphosis
1980Publisher Summary This chapter focuses on the control of postembryonic growth and metamorphosis. It highlights the chemistry, biochemistry, and regulation of prothoracicotropic hormone (PTTH), juvenile hormone, and molting hormone (20-hydroxyecdysone, ecdysterone) in the tobacco hornworm, Manduca sexta, and deals only in a cursory manner with hormone

Studies on insect adipokinetic hormones
General and Comparative Endocrinology, 1972An adipokinetic factor is present in the corpora cardiaca of Schistocerca gregaria, Locusta migratoria, Periplaneta americana, and Tenebrio molitor. A large in vivo adipokinetic response can be demonstrated in the locusts and the mealworm, but not in the cockroaches Periplaneta americana and Gromphadorhina portentosa.

Morphogenetic Action of Insect Hormones
Annual Review of Entomology, 1974Two classes of hormones-ecdysones and juvenile hormones (JH)-regulate the morphogenetic changes of insect metamorphosis. Recent advances in structural analysis and synthesis have resulted in the ready availability of synthetic forms, analogues, and mimics of these hormones; and there has already been considerable speculation on their molecular modes of

Neurosecretory hormones in insects
Endeavour, 1985Abstract Although the existence of hormones in insects has been known for many years, it is only comparatively recently — with the benefit of sensitive new techniques of assay, isolation, and sequencing — that an overall picture of their nature has begun to emerge.

Biochemical Studies on Insect Hormones
1956Publisher Summary The present knowledge of insect hormones can be compared with that of vertebrate hormones available in about 1920. The presence of hormones in the insect kingdom is generally recognized; their centers of production, the endocrine glands, and their physiological effects have been studied in detail by the classical methods of hormone ...

1974
In insects, hormones are involved in the regulation of behavior to a greater extent than in other invertebrate or vertebrate groups. This extensive adoption of hormonal involvement in the function of the nervous system may be partially due to size restrictions and to the rich behavioral repertoires which insects characteristically show.

Proceedings: Animal Sciences, 1985
Hormones play an important role in insect behaviour. These hormones are mainly the neurohormones of the brain and of the corpus cardiacum, the juvenile hormone of the corpus allatum and the ecdysone of the prothoracic glands. These produce either releaser effects or modifier effects.
