Figure 5. Effects of alkenes with different double-bond position on pollinator behavior.

Figure 5

(A) Addition of 9- and 12- alkenes (associated with SAD1/2) onto O. exaltata flowers reduced its pollinator (C. cunicularius) response (N = 18). Red bar, control O. exaltata; pinkish bar, scent manipulated O. exaltata. (B) Adding 7-alkenes (associated with SAD5/6) into O. sphegodes floral scent extract reduced its pollinator (A. nigroaenea) response (N = 17). Blue bar, control floral scent of O. sphegodes; light blue bar, manipulated floral scent of O. sphegodes. Y-axis refers to number of counts. Asterisks indicate statistical significance (pairwise Mann-Whitney U test): *, p<0.05.
