Heads of Spodoptera littoralis males with their antennae artificially elevated and stabilized to imitate their flight posture, were exposed at different inclinations to a mobile beam of pulsed pheromones. The electroantennogram patterns recorded for various linear tracks simulated in this manner were closely linked to the spatial pheromone density distribution. Thus, during in-flight mate detection, the normally elevated antennae appear to function as a sensitive, instantaneous detector of conspecific female sex pheromone, informing the insect of contact with, amount, loss or recovery of the stimulant. © 1984 IRL Press Limited.
