Heather Higo, also out of our lab, showed that QMP caused significant dose-dependent increase in the number of foragers gathering pollen, and individual pollen foragers returned to the nest with larger pollen loads (Higo et al. 1992 Effect of honey bee queen mandibular gland pheromone on foraging and brood rearing. Canadian Entomologist 124:409-418). She only found this difference in colonies just established from packages, and has done two years of work that seems indicate these differences do not occur in established colonies.
