Respiratory and Glandular Systems

1 . What is the function of the hypo-pharyngeal gland in the pharynx of the worker bee?

Secretes royal jelly

2 . In the queen, what does the mandibular gland secrete?

Queen pheromone

3 . What is the Nasonov gland? What is its function and what does it secrete?

The Nasonov gland is located on the abdomen and secretes the Nasonov pheromone The pheromone is used to attract workers to food and to orient lost or disoriented workers to home and to mark water supplies

4 . How does the anatomy of the queen and drone differ from the worker bee?

Different in head shape and compound eyes (drones have larger eyes and meet in the middle) The queen has a longer abdomen due to her ovaries The drone has a barrel shaped abdomen to house his reproductive organs Queen has a long-curved stinger that lacks barbs Both drones and queen lack corbiculae (pollen baskets) and the specialized hairs on the legs since neither collects pollen Both drone and queen take food from the worker and neither have well developed mouth parts or honey stomachs Both drone and queen lack wax and scent glands Glands in both queen and drone are different from worker glands The queen has specialized glands in her mandible that produce queen pheromone In drones the mandibular and hypopharyngeal glands are not developed
