Defining behavioral and molecular differences between summer and migratory monarch butterflies
BMC 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]
PeerJ, 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.

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

A simplified method for synthesizing juvenile hormone-protein conjugates.
Journal of Lipid Research, 1990 A convenient and simple method is presented for the synthesis of juvenile hormone-thyroglobulin conjugates. Methods previously described for this hapten linkage have used a two-step process in which a reactive intermediate was isolated and then used for ...

Root‐Stimulated Movements in Mimosa Pudica for Biohybrid Robotic Systems
Advanced Robotics Research, EarlyView.This study demonstrates that thermal and electrical stimulation of Mimosa pudica root induces movement of the petiole and pinnules without direct stimulation of the aerial organs, thereby enabling a plant‐based robotic gripper and providing a foundation for the development of intelligent and sustainable systems.
