Olfactory active compounds were identified from the female gland extracts and from the host-volatile components in the Sparganothis fruitworm, Sparganothis sulfureana Clemens (Lepidoptera: Tortricidae), using GC-EAD and GC-MS. Olfactory activities of these compounds were further investigated by electroantennogram and single cell recording techniques. Characteristic pheromone-sensitive neurons and host-volatile-sensitive neurons were identified, and most of these neurons were specialized to specific compounds. Although most sensilla contained either sex-pheromone-sensitive neurons or host-volatile-sensitive neurons, there was a characteristic sensilla population that contained neurons responding to both sex pheromone and specific plant volatile components, and the response profile of these sensilla were highly sensitive and specialized as well.
