Electrophysiological responses of antennal neurons to the plant-related volatiles were investigated in the corn earworm Helicoverpa zea and the tobacco budworm Heliothis virescens. Males of each species have three distinct types of olfactory sensilla responding to the sex pheromone-related compounds. Single cell responses of these sensilla to sex pheromone and plant-odor-related compounds were characterized in the present study. Neuroanatomical olfactory pathways of the pheromone and plant-odor-sensitive neurons were also investigated.
