In the honey bee colony queen rearing is usually suppressed by releaser effects of the queen's pheromone. This is part of the dominance hierarchy maintaining the monogynous homeostasis. Under queenless conditions, the queen's control over the construction of emergency queen cells by the workers can be substituted by exposure to only one component of the mandibular pheromone secretion of a queen, the main compound (E)-9-oxo-2-decenoic acid. A novel and simple synthesis of (E)-9-oxo-2-decenoic acid is described, and a bioassay was developed by which a dose-dependent effect of synthetic (E)-9-oxo-2-decenoic acid presented on a dummy bee was evaluated.
