EAG responses recorded from the driver, responder, and F1 crossing expressing the pheromone receptor from the silkworm moth, BmorOR1. Responses elicited by bombykol in the Orco-GAL4, UAS-BmorOR1 flies were significantly higher than those recorded from control flies. 2-Heptanone elicited robust responses in all lines. Source doses: 2-heptanone, 100 µg; bombykol, 50 µg. N = 6
