Although degradation plays a role, JH titer is primarily determined by the rate of biosynthesis in the corpora allata gland (CA).
In summary, integrative approaches using CA metabolomics, genomics, and proteomics are promising tactics to identify regulatory points in the flux of precursors in the JH synthesis pathway and unveil the molecular mysteries of a complex metabolic system such as the synthesis of juvenile hormone in the corpora allata of insects.

Typically, the RCC consists of paired corpora cardiaca (CC) and paired corpora allata
(CA) (Cazal 1948).

An allatostatic factor and juvenile hormone synthesis by corpora allata in Locusta migratoria.
2008), identificandose como corpora allata y corpora cardiaca (Fig.
Las corpora cardiaca, junto con las corpora allata, el ganglio subesofagico y el cerebro, forman un complejo neurosecretor que se encarga de producir varios grupos de neuropeptidos (Nps) que actuan como mensajeros quimicos extracelulares.
Siva-Jothy and Rolff permitted some of their beetles to mate, then transferred the insects' corpora allata to virgin beetles.
When virgins received corpora allata from mated beetles, their phenoloxidase activity dropped--about a fifth for males and a half for females--compared with virgins receiving transplants from unmated donors.
The corpora allata (CA) arise in early embryonic development (40%D) from intersegmental invaginations anterior to the maxillary segment (Gassier 1998).
This hormone activates the corpora allata and the prothoracic glands responsible for regulating growth (Wigglesworth 1972).
