Distribution of honeybees on brood National Institute of Agronomic Research
Furgala, B.; Boch, R..
It is generally accepted that caste determination in the honeybee (Apis mellifera L.) is a result of differences in the composition of the larval food. It has been assumed that the glandular secretions of the nurse bee, and the type and age of larvae fed, may change as the nurse bee becomes older. Free (1960) recently investigated this possibility by comparing the distribution of bees of known ages on combs containing brood of known ages. We approached this question in a similar manner. The following is a preliminary account of some of our results.

Identification of geraniol as the active component in the Nassanof pheromone of the honey bee National Institute of Agronomic Research
Boch, R.; Shearer, D.A..
Honey bees (Apis mellifera L.) attract each other by a variety of biological stimuli. The olfactory stimulus produced by the worker bees has received attention during a number of investigations ever since Sladen1 suggested that the attractant odour originated from a special organ discovered by Nassanoff in 1883. This scent organ is located on the anterior part of the seventh abdominal tergum of the worker bee.

Identification of iso-amyl acetate as an active component in the sting pheromone of the honey bee National Institute of Agronomic Research
Boch, R.; Shearer, D.A.; Stone, B.C..
The sting of the honey bee (Apis mellifera L.) carries volatile substances which incite bees to aggression. This was first demonstrated by Huber, who elicited attacks by the guard bees when he placed freshly excised stings or the odour of stings near the hive entrance. Free found that cotton balls containing stings were more frequently stung than control balls.

Identification of nerolic and geranic acids in the Nassanoff pheromone of the honey bee National Institute of Agronomic Research
Boch, R.; Shearer, D.A..
In an earlier paper we reported the identification of geraniol as a predominant component of the scent which is produced by the Nassanoff organ of the honey bee. Field tests by Free and unpublished observations of our own, however, showed that geraniol was much less attractive to bees than was the complete scent. Therefore, an attempt was made to detect and identify other fractions of this scent and test these on bees.

Production of geraniol by honey bees of various ages National Institute of Agronomic Research
Boch, R.; Shearer, D.A..
The amount of geraniol obtained by a standard procedure from the Nassanoff gland of the honey bee varied from zero to 1·5 μg per bee, depending on the age of the bees. Newly emerged bees had no geraniol. Guard bees produced ca. 0·3 μg per bee and a marked increase to ca. 1·0 μg per bee occurred when the bees began to forage.
