The function of the corpora cardiaca is not completely clear but the corpora allata produces a substance called juvenile hormone (JH). The other two endocrine glands are the corpora cardiaca and corpora allata that are connected by nerve fibers to each other and to brain neuro-secretory cells. This gland produces a substance called ecdysone that controls molting in the larva and pupa this gland is not present in the adult bee. The prothoracic gland is a very small leaf-like structure situated between the first two of the three thoracic segments. Larval honey bees have three important endocrine glands that are involved in their growth and development. In some cases, a single hormone may have multiple targets and different effects in each target. Their effect may be stimulatory or inhibitory. Although typically produced in very small quantities, hormones may cause profound changes in their target cells. They are often regarded as chemical messengers. Hormones only affect the individual that produces them.
