Electroantennogram dose-response profiles constructed from mean (± SE) antennal responses of female <i>Xyleborus glabratus</i>.

<p>Test substrates included freshly-rasped wood of silkbay <i>Persea humilis</i>, a commercial manuka oil lure, and synthetic α-copaene. Responses are expressed as normalized percentages relative to a standard reference compound (ethanol, 2 ml saturated vapor). Dose-response curves generated with hyperbolic regression models (see text).
