Fig. 1.
Effect of defensive compounds topically applied onto live crickets on the attack rate of Harpegnathos saltator ants. 4OHE and the combination of 4ODE and C13 resulted in reduced attack by ants. 4OHE=4-oxo-(E)-2-hexenal; 4ODE=4-oxo-(E)-2-decenal; C13= n-tridecane. Numbers inside bars indicate sample size, and letters indicate statistical significance: different letters represent significant difference according to Fisher's Exact test (P<0.05). Different color bars represent control (white) or treatment (grey)
