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 vaccinii-corymbosi which infects open blueberry flowers through the gynoecial pathway causing mummy berry(More)
The carpenter bee, Xylocopa virginica (L.), acts as a primary nectar 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(More)
