Interpretive Summary: Africanized honey bees have now infiltrated much of the SW United States and displaced their European honey bee counterparts in the wild. Their defensive behavior is well-documented, but an understanding of other aspects of their biology, especially foraging, are essential in order to fully assess their impact in both management agriculture and the natural environment. In this experiment we sought to compare the pollen collection behavior of European and Africanized bees when exposed to artificially supplanted chemical cues, brood pheromones, known to be present on growing bee larvae. It was found that European honey bees responded more strongly to the pheromone as shown by an increased ration of pollen foragers in treated colonies. In addition, we were able to show through other studies that Africanized honey bees responded to lower sucrose concentrations than European honey bees. The different responses of the two bee races suggested that the response to sugar concentrations was not a good predictor for comparative foraging behavior. Part of this is attributed to the more defensive nature of the Africanized bee.
