Fig. 2.
Dose response curves for (E)-2-hexenal (2-hex; N=19) and (E)-2-decenal (2-dec; N=10), and their respective combinations with n-tridecane (C13), on the attack rate by individually-caged Harpegnathos saltator ants. Asterisks indicate statistically significant difference from control, as tested by Fisher's Exact test (P<0.05). No synergistic effect of C13 was observed
