Figure 2. Response of Pseudomyrmex spinicola ants to isolated compounds from Piezogaster reclusus.
Bars show the mean proportion (± SE) of encounters in which Pseudomyrmex spinicola ants attacked cotton swabs that were treated with Piezogaster reclusus (A) cuticular compounds or (B) glandular compounds in comparison to controls. Letters indicate significant differences from binomial GLMMs that included ant colony as a random effect.
