摘要
In Aplysia fasciata, pheromones released by conspecifics with access to mates increase the quantity of food eaten. This effect is blocked when the chemosensory rhinophores are ablated, indicating that the rhinophores sense pheromones. The modulation of feeding by pheromones can be monitored by an increase in the amplitude of swallowing movements in the presence of conspecifics with access to mates. Atrial gland homogenates and four bag cell peptides (egg-laying hormone, and alpha, beta, and gamma bag cell peptides) amplify the swallow amplitude in a manner similar to that caused by conspecifics with access to mates, suggesting that peptides from the bag cell/atrial gland family that are released from the atrial gland into the surrounding water may be pheromones regulating feeding and reproductive behaviors.
