Olfaction in Manduca sexta: Cellular Mechanisms of Responses to Sex Pheromone

摘要: In insects, olfaction plays a major role in the control of many kinds behavior. Orientation and movement toward, interactions with, receptive mating partners, appropriate sites for oviposition, sources food, hosts parasitism usually involve olfactory signals that initiate, sustain, guide behaviors. Because their prominence zoosphere, economic medical importance, usefulness as models both behavioral neurobiological research, insects have been extensively studied by investigators interested mechanisms Insects respond to variety semiochemicals, including pheromones (chemical messengers within species, such sex attractants) kairomones between species adaptively favorable recipient, attractants stimulants oviposition feeding emitted host plant). Studies insect responses biologically significant odors shown quality quantity odorants complex mixtures present environment are encoded patterns activity multiple receptor cells (ORCs) antennae. These ‘messages’ decoded integrated centers central nervous system (CNS), it is there olfactorily induced changes behavior or physiology initiated.
