EFFECT OF THE COMPONENTS OF THE NASONOV PHEROMONE ON ITS RELEASE BY HONEYBEES AT THE HIVE ENTRANCE
J. B. FREE, A. W. FERGUSON AND J. A. PICKETT
Synthetic (E)-citral, geraniol, nerolic acid and geranic acid components of the Nasonov gland pheromone induce worker honeybees (Apis mellifera) to release Nasonov pheromone at their hive entrance. Mixtures lacking anyone of these 4 components stimulated pheromone release less effectively, but absence of neroI or (E,E)-farnesol increased effectiveness. The implication of these results for the development of a lure to attract honeybee swarms is discussed.
