    Describe the Pheromone glands of the honey bee? that was the question but all answers I see mention the Mandibular glands, and Salivary glands are they technically pheromone glands as they don't have ducts to the external skeleton.

    Both glands have ducts outwards, but only the mandibular gland produces pheremones (but it's more complicated than that, depending on whether she is a queen or a worker, and the age of the worker). The pheremone gland you're probably most familiar with and have seen a lot in action is the Nasanov gland at the tip of the worker's abdomen - but there are quite a few more.

    I highly recommend Celia Davis, 'The Honey Bee Inside Out'. That book has helped me enormously to understand the working of bees a bit better - but I have a lot more to learn.

    I Have listed the following Mandibular Gland, Dufor Gland (Alkaline Gland), Arnhart Gland (Footprint or Trail Gland) Nasanov gland, Renner Baumann Gland (Tegrite Gland) Koschevnikos Gland, and Wax Glands, I also added Mandibular glands. When answering the question.

    Wax glands produce wax - not pheremones.
