Figure 3

First arm choice of T. peregrinus adults in Y-tube olfactometer tests. Bars show the percent (numbers within bars) of insects choosing the stimulus arm (black bars) or the control arm (white bars). (a) Response of females and males to volatiles from live males versus control. (b) Response of one- and two-week-old (w/o) males to male volatile extracts versus hexane. (c) Response of one- and two-week-old males to synthetic 3-methylbut-2-enyl butanoate versus hexane. All treatments and controls included 2 leaves of E. tereticornis. Asterisks indicate significance levels in Chi-square tests (^∗𝑃<0.05; ^∗∗𝑃<0.01; ^∗∗∗𝑃<0.001).
