Defining behavioral and molecular differences between summer and migratory monarch butterflies

open access: yesBMC Biology, 2009
Background In the fall, Eastern North American monarch butterflies (Danaus plexippus) undergo a magnificent long-range migration. In contrast to spring and summer butterflies, fall migrants are juvenile hormone deficient, which leads to reproductive ...

Reconstruction of insect hormone pathways in an aquatic firefly, Sclerotia aquatilis (Coleoptera: Lampyridae), using RNA-seq [PDF]

open access: yesPeerJ, 2019
Insect hormones: ecdysteroids and juvenile hormones have crucial functions during the regulation of different developmental pathways in insects. Insect metamorphosis is one of the primary pathways regulated by these hormones.

Juvenile Hormone Induction of Esterases: A Mechanism for the Regulation of Juvenile Hormone Titer [PDF]

open access: yesProceedings of the National Academy of Sciences, 1972
Within a few hours after injection of juvenile hormone into Hyalophora gloveri pupae, several fast-migrating carboxylesterases (EC 3.1.1.1) that are sensitive to di iso propylfluorophosphate appear in the hemolymph. Treatment of the pupae with puromycin

Identification and Functions of JHE 6 Specifically Expressed in Bombyx mori Silk Gland

open access: yesInsects, 2023
Juvenile hormone esterase (JHE) is the specific enzyme that degrades juvenile hormone (JH) and regulates the JH titer in insects. JH also regulates the development of the silk gland and the synthesis and secretion of silk proteins in Bombyx mori.
