[termites] endocrinological scale |
 | | Although the presence of soldiers in termite colonies inhibits further soldier differentiation, juvenile hormone, secreted in corpora allata located behind the brain, influences growth. |
 | | JH (neotenin) ensures growth of larva, while preventing metamorphosis. |
 | | JH also has a prothoracicotropic (hormone that stimulates the prothoracic glands to synthesize and release ecdysone, and is therefore a key hormone for the regulation of insect molting and metamorphosis) action as it induces molts. |
