[The role of the prothoracic glands in the production of ecdysone during the last larval instar of Locusta migratoria L]. 1975

J A Hoffmann, and J Koolman, and C Beyler

Tritiated cholesterol is rapidly converted to labelled ecdysone in vitro by prothoracic glands from last instar larvae of Locusta at the time of the maximum endogenous hormone increase of the insects. Glands from larvae with low hormone content or fat body fragments do not make similar conversions.

D002784 Cholesterol The principal sterol of all higher animals, distributed in body tissues, especially the brain and spinal cord, and in animal fats and oils. Epicholesterol
D004440 Ecdysone A steroid hormone that regulates the processes of MOLTING or ecdysis in insects. Molting Hormone
D006110 Grasshoppers Plant-eating orthopterans having hindlegs adapted for jumping. There are two main families: Acrididae and Romaleidae. Some of the more common genera are: Melanoplus, the most common grasshopper; Conocephalus, the eastern meadow grasshopper; and Pterophylla, the true katydid.

D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
