TLDR
JH titer was determined in the haemolymph of penultimate and last instar larvae of Pieris Brassicae L. and Barathra brassicae and the differences observed were consistent with physiological differences between the two species.Abstract:

Ecdysone-induced change in cellular commitment of the epidermis of the tobacco hornworm, Manduca sexta, at the initiation of metamorphosis.
TL;DR: It is concluded that the change to pupal commitment occurs in a three-step sequence: the acquisition of the competence to form pupal cuticle in response to ecdysone, the loss of responsiveness to JH, and the lost of the ability to produce larval cuticle.

Juvenile hormone esterase activity in precisely timed last instar larvae and pharate pupae of Manduca sexta
TL;DR: Two peaks of activity were observed, one just before wandering and the other just before larval-pupal ecdysis, which indicated that JHE activity during the instar and pharate pupal life is high.

A role of juvenile hormone in pupal development of the tobacco hornworm, Manduca sexta

TL;DR: Application of juvenile hormone just before the onset of ocellar retraction at the beginning of the prepupal period prevents this precocious adult differentiation in the tobacco hornworm.

Simultaneous determination of molting and juvenile hormone titers of the greater wax moth

TL;DR: The significance of MH and JH titers as related to the endocrine regulation of development is discussed in the light of this finding.

Hormonal control of storage protein synthesis and uptake by the fat body in the silkworm, Bombyx mori
TL;DR: It is suggested that storage protein synthesis is induced in the absence of juvenile hormone by some supplementary stimulus, possibly the supply of nutrient after feeding, and uptake is induced by ecdysteroids after a decline in the juvenile hormone level.

The juvenile hormone. ii. its role in the endocrine control of molting, pupation, and adult development in the cecropia silkworm
TL;DR: The corpora allata show low but definite activity at the time of pupation, and the low concentration of juvenile hormone in the mature larva plays a definite role in the endocrine control of the Cecropia silkworm.

Juvenile hormone regulation of the larval diapause of the Southwestern corn borer, Diatraea grandiosella☆
C.-M. Yin,G.M. Chippendale +1 more
TL;DR: The findings suggest that the initiation and maintenance of diapause are regulated by juvenile hormone titre, and that larvae retain a high titre of juvenile hormone until the last stages of diAPause.

Histology of the corpora allata of melanoplus differentialis (orthoptera: saltatoria)
TL;DR: The glandular cells, both normal and polyploid, show characteristic changes related to secretory activity and inactivity which are fundamentally the same in nymphs and adults and in both sexes.
