AbstractThe intra-nest transmission of two aromatic components of honey bee queen mandibular gland pheromone, 4-hydroxy-3-hydroxyphenylethanol (HVA) and methyl p-hydroxybenzoate (HOB), is quantitatively described. After being secreted onto the body surface of the queen, the greatest quantities of HVA and HOB are removed by workers in the queen’s retinue, especially those contacting the queen with their mouthparts. Other workers acquire pheromone components via direct contact with retinue bees or with other workers that have already acquired queen pheromone. HVA and HOB can also reach workers through queen or worker "footprints," although the relatively little material deposited onto the comb wax becomes less available with time, presumably because of diffusion into the wax. Pheromone material is removed from circulation by being internalized into workers, the queen, and the wax. Rates of HVA and HOB transfer between different entities within the nest are described in terms of pseudo first-order rate constants. The intra-nest transfer of these two components, both qualitatively and quantitatively, is similar to that described earlier for the most abundant queen mandibular gland pheromone component, 9-keto-2-(E)-decenoic acid (9-ODA; Naumann et al. 1991). Thus, the queen mandibular gland pheromone complex is transferred through the nest as a unit rather than as individual components moving at different rates.
