Increased behavioral sensitivity to the pheromone after brief exposure of the whole insect to the sex pheromone has been documented in antennal lobe neurons of Spodoptera littoralis. We investigated whether a brief stimulus of the major component of the pheromone on naïve antenna separated from the head increased the electroantennographic responses after successive stimulations at different times. The response increase was clear 30 min after the first stimulation, and this effect lasted at least 60 min, the average life time of the antenna. Our results suggest that the olfactory receptor neurons, and not only the neurons in the antennal lobe, may be involved in the increased antennal response after a single pheromone pulse.
