Pheromones released during mating and egg laying in Aplysia facilitate various aspects of behavior. We now show that the chemosensory rhinophores sense these pheromones. Ablating the rhinophores causes a significant decrease in the time spent mating. In addition, the lesion blocks the increases of feeding in response to pheromones released by egg cordons and by mating conspecifics. Respiratory pumping is significantly increased in response to egg cordons, mating conspecifics and egg laying hormone (ELH). The increase in response to egg cordons is blocked by ablating the rhinophores, but not by lesioning the osphradium, a second chemosensory organ.
海兔在交配和产卵过程中释放的信息素会促进行为的各个方面。我们现在表明，化学感觉的嗅角能感知这些信息素。切除嗅角会导致交配时间显著减少。此外，该损伤会阻止对卵带和交配同种个体释放的信息素作出反应时摄食的增加。对卵带、交配同种个体和产卵激素（ELH）的反应会使呼吸泵动显著增加。对卵带反应的增加可通过切除嗅角来阻断，但切除第二化学感觉器官嗅检器则无法阻断。
