    Notes: Abstract The unusual venom of Apis cerana contains large oily droplets within an otherwise aqueous secretion. Chemical analysis (GC-MS) revealed that the venom oil consists of (Z)-11-eicosen-1-ol (81.2%), other linear alcohols (7.7%), and linear hydrocarbons (11.1%). The eicosenol is present in extremely large quantities, averaging over 250 μg per insect, and is absent, or present in small quantities, in other parts of the sting apparatus. An investigation of the site of eicosenol storage in A. mellifera showed it to be absent from the venom and to be associated with the setose area where the more volatile components of the alarm pheromone are stored, as previously shown by others. A third honeybee species, A. dorsata, does not to contain the alcohol. The function of eicosenol in A. cerana in not clear, but may serve to mark stung intruders with pheromone or to attract foragers to marked floral resources.

    Attractant or Pheromone: The Case of Nasonov Secretion and Honeybee Swarms (1999)

    Notes: Abstract Honeybees are attracted to a variety of odors, including the secretion of their Nasonov glands, a secretion that has been widely assumed to be an orientation and attraction pheromone. A crossover design experiment comparing synthetic Nasonov secretion with linalool, oil of clove, skatole, and wax moth sex pheromone was established to determine if Nasonov secretion serves as a true pheromone or is simply a general attractant for honeybee swarms. None of the test odors was more attractive than odorless controls, and in all comparisons, synthetic Nasonov secretion was significantly more attractive than the test odors or odorless controls. The results confirm that Nasonov secretion is a true pheromone in the context of attracting honeybee swarms to nest cavities and that environmentally present or apparent odors play little or no role in honeybee nest-seeking behavior.
