TLDR
It is concluded that factors are elaborated by the pars intercerebralis, then stored and activated in the neurohaemal part of the corpora cardiaca: these organs alone do not control flight tendency.About:

Locust Phase Polymorphism and its Endocrine Relations
TL;DR: Locust phase polymorphism evolved several times by convergent evolution within the family of acridids, and species dependent differences, both in certain phase characteristics and in the amplitude of their changes, may be well explained.

Insect Flight Metabolism
Ann E. Kammer,Bernd Heinrich +1 more
TL;DR: This chapter focuses on the various adaptations that make possible the high metabolic rates necessary for flight, which are achieved by a complicated meshwork of neural, hormonal, and biochemical mechanisms.

The Endocrine Control of Flight Metabolism in Locusts
G. J. Goldsworthy,C. H. Wheeler +1 more
TL;DR: Hormones play an important role in coordinating the supply and utilisation of fuels during sustained flight in locusts, and this will be the major theme of this review.
Book ChapterDOI
Hormonal Control of Insect Migratory Behavior
TL;DR: A model in which adult migration was triggered when ecdysone was absent and the juvenile hormone (JH) titer was low was put forth, in which the rise in JH titer then caused both the cessation of migratory behavior and the onset of oogenesis.

Fat combustion and metabolic rate of flying locusts (Schistocerca gregaria Forskål)
TL;DR: The nature and the amount of fuel used by flying Schistocerca gregaria Forskål have been estimated from direct analyses of the total content of fat and glycogen in control groups and in the corresponding flying groups, i.e. groups which had flown continuously for several hours.

Control of haemolymph lipid concentration during locust flight: An adipokinetic hormone from the corpora cardiaca
R.J. Mayer,David J. Candy +1 more
TL;DR: It is proposed that the control of the diglyceride concentration of locust haemolymph during flight is mediated, at least in part, by a peptide hormone released from the corpora cardiaca.
Journal ArticleDOI
Studies on insect adipokinetic hormones
TL;DR: An adipokinetic factor is present in the corpora cardiaca of Schistocerca gregaria, Locusta migratoria, Periplaneta americana, and Tenebrio molitor and can be demonstrated in the locusts and the mealworm, but not in the cockroaches Peri PLANETA americana and Gromphadorhina portentosa.

The physiological effects of corpus cardiacum extracts in locusts.
W. Mordue,G.J. Goldsworthy +1 more
TL;DR: Extracts of locust corpora cardiaca accelerate heart beat, increase amaranth excretion through the Malpighian tubules, and increase the active phosphorylase levels in the fat body.
Journal ArticleDOI
Biology and Physics of Locust Flight. IV. Notes on Sensory Mechanisms in Locust Flight
TL;DR: The flight behaviour of the desert locust was studied under various experimental conditions in order to find which external factors can initiate, maintain or alter the wing movements, excluding reactions which depend upon higher nervous centres.
