. Two pheromone components are required to elicit close‐range precopulatory behaviour in male lightbrown apple moths, Epiphyas postvittana (Walker) (Lepidoptera). The receptor cells which respond to the major component (I) ( E )‐11‐tetradecen‐1‐yl acetate, have a fast disadaptation rate with recovery occurring within 5 s after stimulation, while the cells responding to the second component (II), ( E, E )‐9, 11‐tetradecadien‐1‐yl acetate, recover after approximately 300 s. Studies on the behaviour of males in the laboratory show a close correlation between the duration of a memory effect, during which males will respond to compound I alone after receiving an initial exposure to I and II, and the time‐course for disadaptation of component II‐responding cells. These results suggest several possibilities for mechanisms of integration of sensory input by the CNS.
