In a 2-yr field study, mature orchard plants of rabbiteye blueberry (Vaccinium ashei Reade variety 'Climax'), plus potted pollenizers ('Premier') were caged with varying densities of honey bees (0, 400, 800, 1,600, 3,200, 6,400, or 12,800 bees plus open plot) during the bloom interval. The rate of legitimate flower visits tended to increase as bee density(More)
Honey bees are important pollinators of commercial blueberries in the southeastern United States, and blueberry producers often use supplemental bees to achieve adequate fruit set. However, honey bees also vector the plant pathogenic fungus Monilinia vacciniicorymbosi which infects open blueberry flowers through the gynoecial pathway causing mummy berry(More)
Carpenter bees (Xylocopa spp.) act as primary nectar thieves in rabbiteye blueberry (Vaccinium ashei Reade), piercing corollas laterally to imbibe nectar at basal nectaries. Honey bees (Apis mellifera L) learn to visit these perforations and thus become secondary nectar thieves. We tested the hypothesis that honey bees make this behavioral switch in(More)
Thecarpenterbee,Xylocopavirginica(L.), acts as aprimarynectar thief in southeastern plantations of native rabbiteye blueberry, Vaccinium ashei Reade, perforating corollae laterally to imbibe nectar. Honey bees, Apis mellifera L., learn to collect nectar from these perforations and thus become secondary thieves. We conducted a 2-yr study to assess how nectar(More)
In a 2-yr Þeld study, mature orchard plants of rabbiteye blueberry (Vaccinium ashei Reade variety ÔClimaxÕ), plus potted pollenizers (ÔPremierÕ) were caged with varying densities of honey bees (0, 400, 800, 1,600, 3,200, 6,400, or 12,800 bees plus open plot) during the bloom interval. The rate of legitimate ßower visits tended to increase as bee density(More)
In a 2000 field study in which mature plants, potted pollenizers, and 0-12800 honey bees were tented together, honey bees were shown to effectively pollinate rabbiteye blueberry, variety “Climax.” There was a consistent and significant increase in fruit-set and number of seeds as bee numbers increased within the range of 0-6400 bees. In conference, the(More)
