Table 1. Vibration signal performance and arousal: overlap of genes regulated in vibration signal performers and bees exposed to different pheromones.

	V+↑ (412)	V+↓ (491)	χ2 and p-values
Alarm pheromone ↑ (237)	22 [32%]	12 [17%]	χ2 = 10.65
Alarm pheromone ↓ (201)	8 [12%]	27 [39%]	p<0.005
Queen mandibular pheromone ↑ (374)	15 [21%]	25 [35%]	χ2 = 7.11
Queen mandibular pheromone ↓ (323)	23 [32%]	9 [13%]	p<0.01
Brood pheromone ↑ (122)	14 [27%]	8 [16%]	χ2 = 1.10
Brood pheromone ↓ (106)	13 [26%]	16 [32%]	p = 0.29

Number and direction of expression (indicated by arrows) of genes that are differentially regulated in V+ and V− bees and also by one or more pheromone. Gene expression data were taken from [9] for queen mandibular pheromone and from [8] for brood pheromone. Numbers in parentheses are the total number of genes from each experiment. Numbers in brackets are the percentages of genes regulated in V+ bees that are up- or downregulated by pheromones. Chi-square tests with Yates correction were performed.
