✅Explanation:
-Endocrine Glands: The corpora allata are a pair of endocrine glands found in insects.
-Hormone Function: Juvenile hormone (JH) plays a crucial role in insect development, particularly in regulating metamorphosis.
-Maintaining Larval Stage: JH prevents insects from molting into adults prematurely, ensuring they remain in the larval stage and continue to grow.

🔑Key Points:
-Juvenile Hormones
-They are a group of acyclic sesquiterpenoids.
-It regulates many aspects of insect physiology.
-Vincent Wigglesworth discovered Juvenile Hormones.
-These hormones regulate development, reproduction, diapause, and polyphenisms.
-Juvenile Hormones were formerly called neotenin.
-These hormones are secreted by a pair of endocrine glands behind the brain known as corpora allata.
