Fig 3. Behavioral responses of V-V transplant male controls.

Of 43 males that exhibited positive behavioral responses, 42 responded only to the H. virescens blend (Z11-16:Ald + Z9-14:Ald, 1:0.1). Only a single male responded to the H. zea blend (Z11-16:Ald + Z9-16:Ald, 1:0.1). Source contact (SC) is indicated by dark green, half way to the source (Mid) by a lighter green and upwind flight (UP) by orange. Ratios of odorants in each blend are indicated above the four treatments.
