The Nasonov (alternatively, Nasanov) pheromone is released by worker bees to orient returning forager bees back to the colony. To broadcast this scent, bees raise their abdomens, which contain the Nasonov glands, and fan their wings vigorously.
Nasonov includes a number of different terpenoids including geraniol, nerolic acid, citral and geranic acid. Bees use these to find the entrance to their colony or hive, and they release them on flowers so other bees know which flowers have nectar.
A synthetically produced Nasonov pheromone can be used to attract a honey bee swarm to an unoccupied hive or a swarm-catching box. Synthetically produced Nasonov consists of citral and geraniol in a 2:1 ratio.
