The Nasonov pheromone of the honeybee<i>Apis mellifera</i> L. (Hymenoptera, Apidae). Part II. Bioassay of the components using foragers

The Nasonov pheromone of the honeybee comprises seven components, ( Z )-citral, nerol, geraniol, nerolic acid, geranic acid, and ( E,E )-farnesol. Bioassay of individual components showed each attracted foraging bees. A mixture of components in proportions present in the honeybee was as attractive as the natural secretion, and each component contributed to the attractiveness of the mixture. Honeybees responded anemotactically to the source of Nasonov odor. The presence of footprint pheromone enhanced the attractiveness of the synthetic Nasonov mixture. Nasonov and footprint pheromones may prove useful in attracting honeybees to crops needing pollination.
