In honey bees, the nutritive food ‘royal jelly’ or ‘bee milk’ is produced by:

  • A.mandibular gland
  • B.lateral pharyngeal gland
  • C.cephalic salivary gland
  • D.thoracic salivary gland

Answer: B

Royal jelly is produced by the lateral pharyngeal glands, also known as the hypopharyngeal glands, of nurse bees. It is fed to the larvae and to the queen.

Mandibular glands add some fatty acids, while the cephalic and thoracic salivary glands are not the source of the jelly.

Nurse bees make royal jelly from secretions of their glands in the head. Royal jelly is the sole food of the queen larva and the adult queen.
