Experiment 4 eβ and QMP interaction. a Mean (+S.E.) ovary activation by treatment; b mean (+S.E.) ovary activation by treatment and replicate; c mean (+S.E.) ovary activation by ovary size; d mean (+S.E.) ovarioles by ovary state and treatment; e mean (+S.E.) HPG by treatment and ovary state. eβ = e-beta; QMP = synthetic queen mandibular pheromone, large = 8 or more ovarioles; small = <8 ovarioles; activated = one ovary at stage 2 or more; for 6e) activated >0 = one ovary at stage 1 or more; N = 240 bees, 60 per treatment, 30 per replicate, 10 bees per cage.
