We recorded responses from single olfactory receptor neurons in the trichoid sensilla of male univoltene Z strain European corn borers (Ostrinia nubilalis), Asian cornborers (O. furnacalis), and bidirectional F1 hybrids. Responses of parental sensilla were similar to those observed in previous studies. Hybrid receptor neurons were responsive to all tested compounds, but were more sensitive to European than Asian corn borer pheromone components.


Species 1: Lepidoptera Crambidae Ostrinia nubilalis (European corn borer)
