Honey Bee Inhibitory Signaling Is Tuned to Threat Severity and Can Act as a Colony Alarm Signal
The effect of hornet attacks upon (A) foragers (49 trials: 17, 16, and 16 from colonies 1, 2, and 3, respectively) and (B) at the nest entrance upon stop signaling and waggle dancing (60 trials: 20, 22, and 18 from colonies 1, 2, and 3, respectively). The colony schematic shows the location of the nest entrance (Ent) and the two comb zones (Z1 = dance floor) and (Z2). Graphs show the mean ± 1 standard error. Different letters indicate significant differences (Tukey’s HSD test, p < 0.05).
