Percent response of 343 O. nubilalis Z race males tested to treatments in the following order: O. furnacalis 2:1 Z/E blend (ACB, test 1), O. furnacalis 97:3 Z/E blend (ACB, test 2), and then to the 97:3 Z/E O. nubilalis blend (ECB, test 3). Values are for 4 behaviors: taking flight, 150 cm; initiation of upwind flight, 140 cm; upwind flight to the 40 cm mark, and touching the source, 0 cm. For each behavior/distance from source, letters that differ between blends are significantly different (χ²; P < 0.05).
