Peptidomics of the locust corpora allata: identification of novel pyrokinins (-FXPRLamides)
Peptides, 2003The peptidomes of the corpora allata of Locusta migratoria and Schistocerca gregaria were investigated by both matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) and nanoscale liquid chromatography quadrupole time-of-flight tandem mass spectrometry (nanoLC-Q-TOF MSMS). The pyrokinin (-FXPRLamide) family seems to

Peptidergic Control of the Corpus Cardiacum-Corpora Allata Complex of Locusts
1998The brain-corpora cardiaca-corpora allata complex of insects is the physiological equivalent of the brain-hypophysis axis of vertebrates. In locusts there is only one corpus cardiacum as a result of fusion, while most other insect species have a pair of such glands.

Reactivation of corpora allata in pharate adult Manduca sexta
Journal of Insect Physiology, 1994Abstract The stage at which corpora allata (CA) of Manduca sexta regain the capability for juvenile hormone (JH) biosynthesis during adult development was determined by a transplantation assay and in vitro experiments with CA of adults and pharate adult stages 8 through 11.

Ultrastructural characteristics of insect corpora allata in relation to larval diapause
Cell and Tissue Research, 1979The ultrastructure of active and inactive corpora allata from last instar larvae of the southwestern corn borer, Diatraea grandiosella, was examined. Active glands were obtained from pre-, early, and mid-diapausing larvae; inactive ones from late and non-diapausing larvae.

CONTROL OF CORPORA ALLATA FUNCTION IN LARVAE OFGALLERIA MELLONELLA
The Biological Bulletin, 19751. The implantation of three brains into freshly ecdysed last instar larvae which possess at least one of the two corpora allata induces extra larval development. Implanted brains appear to produce a neurohumoral allatotropic factor.2. Corpora allata seem to be inhibited via their nervous connections 48-60 hours after the last larval-larval ecdysis and

Patterns of Corpora Allata Activity in Ovariectomized Blattella germanica
1990The corpora allata (CA) of adult female cockroaches, including Blattella germanica (Gadot et al., 1989a,b), synthesize juvenile hormone-III (JH-III) in a precisely regulated cycle which corresponds to the ovarian cycle. The brain, the ovary and the ootheca have been implicated as the main sources of regulatory factors which modulate the activity of the

Regulation of Corpora Allata Activity and Juvenile Hormone Titer
1989Besides ecdysones, juvenile hormone (JHs) are the only known insect hormones. They are vitally important in the control of several aspects of male and female reproduction, and regulate the development of the insects, ensuring the maintenance of the juvenile characters.

Egg maturation in mosquitoes not regulated by the corpora allata
Journal of Insect Physiology, 1969Abstract Implantation of extra corpora allata from either autogenous or anautogenous donors did not stimulate egg maturation in anautogenous Aedes aegypti or Culex pipiens pipiens fed only on sugar, contrary to the report of Larsen. Implantation of a cockroach corpus allatum did not induce egg maturation in anautogenous mosquitoes fed on sugar ...
