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 response to an energetic advantage realized by nectar-robbing flower visits. Nectar volume and sugar quantity were higher in intact than perforated… Expand

Behavioural differences between male and female carpenter bees in nectar robbing and its effect on reproductive success in Glechoma longituba (Lamiaceae).
TLDR
The differences in food resource preference between male and female bees constitute an optimal resource allocation pattern that enables the visitors to utilise floral resources more efficiently. Expand
Invasive bumble bees reduce nectar availability for honey bees by robbing raspberry flower buds
TLDR
High abundance of invasive bumble bees can reduce resources for managed honey bees by robbing flower buds, revealing a novel, negative impact of bumble bee invasions that could potentially affect honey production. Expand
Nectar Sugar Limits Larval Growth of Solitary Bees (Hymenoptera: Megachilidae)
TLDR
This study suggests that, in addition to pollen, nectarsugar concentration can limit solitary bee larval growth and development, and nectar should be considered more explicitly as a currency governing foraging decisions related to producing optimally sized offspring. Expand
Flower Morphology Influences Pollinator Community with Implications for Cross-Pollination: Observations in Rabbiteye Blueberry (Vaccinium ashei Reade)
TLDR
The distinct and atypical corolla of 'Premier' was taken advantage of to determine how varying floral morphologies might influence pollinator visitation more generally, and to compare bee visitation rates at ‘Premier’ flowers to other common rabbiteye varieties that have more typical flowers. Expand
Effect of Corolla Slitting and Nectar Robbery by the Eastern Carpenter Bee (Hymenoptera: Apidae) on Fruit Quality of Vaccinium corymbosum L. (Ericales: Ericaceae)
Abstract Eastern carpenter bees, Xylocopa virginica (L.) (Hymenoptera: Apidae), are among the most abundant native bee visitors to highbush blueberry, Vaccinium corymbosum L., flowers in the… Expand
Multiple Criteria for Evaluating Pollinator Performance in Highbush Blueberry (Ericales: Ericaceae) Agroecosystems
TLDR
Evaluating pollinators of North Carolina highbush blueberry, Vaccinium corymbosum L., agroecosystems using multiple criteria shows that bee groups contribute to pollination in different ways, and these differences may provide functional complementarity and stability of pollination services to agricultural systems.

Foraging choices balanced between resource abundance and handling concerns: how the honeybee, Apis mellifera, select the flowers of Robinia pseudoacacia.

TLDR
The aim of this study was to understand when and how the bees overcome physical constraints to succeed in flower visits, and to what extent this flexibility extend from the individual to the species. Expand
Nectar robbing improves male reproductive success of the endangered Aconitum napellus ssp. lusitanicum
TLDR
It is demonstrated that A. napellus does not suffer from nectar robbery but may rather benefit via improved pollen dispersal and thus, male reproductive success. Expand
Nectar robbing improves male reproductive success of the endangered Aconitum napellus ssp. lusitanicum
TLDR
It is demonstrated that A. napellus does not suffer from nectar robbery but may rather benefit via improved pollen dispersal and thus, male reproductive success, which may lead to the reduction of geitonogamy or to increased pollen movement. Expand
Floral Nectar Guide Patterns Discourage Nectar Robbing by Bumble Bees
TLDR
This study is the first to show that beyond speeding nectar discovery, a nectar guide pattern can influence bees’ flower handling in a way that could benefit the plant. Expand

Nectar-Robbing Carpenter Bees Reduce Seed-Setting Capability of Honey Bees (Hymenoptera: Apidae) in Rabbiteye Blueberry, Vaccinium ashei, ‘Climax’
TLDR
Assessment of how nectar robbing in honey bees affects fruit production in rabbiteye blueberry found fruit set is higher in open, A, and AX plots than in X and 0 plots, and seed numbers are significantly reduced in AX plots in which X. virginica-induced illegitimate honey bee flower visitation approaches 40%. Expand
Nectar robbing, forager efficiency and seed set : Bumblebees foraging on the self incompatible plant Linaria vulgaris (Scrophulariaceae)
TLDR
It is suggested that nectar robbing has little effect on plant fecundity because legitimate foragers are present in the population, and that seed predation and seed abortion after fertilization may be more important factors in limiting seed production in this species. Expand
Reproductive biology and effect of nectar robbing on fruit production in Macleania bullata (Ericaceae)
TLDR
The frequency of nectar robbing in the studied population was very high (75% of examined flowers) and was positively correlated with reduced fruit set, and the probability of a relation between reduced Fruit set on robbed flowers and an energetic investment is discussed. Expand

TLDR
The results indicate that the nectar robbers have no negative effect on fruit set or seed set in C. caseana and that they may cause increased pollen flow distances by changing the behavior of the pollinator. Expand
Bee foraging behavior and pollinating activity on rabbiteye blueberry Vaccinium ashei Reade
TLDR
Nectar standing crop and nectar production during 24 h were affected by age of flowers and increased significantly in flowers older than one day, and Sucrose concentration was inversely correlated with relative humidity at 24 h and 12 h preceding measurements as well as at the time of measurements. Expand
ARE NECTAR ROBBERS CHEATERS OR MUTUALISTS
TLDR
The effects of nectar robbers are complex and depend, in part, on the identity of the robber, the Identity of the legitimate pollinator, how much nectar the robbers remove, and the variety of floral resources available in the environment. Expand
Changes in the thoracic temperature of honeybees while receiving nectar from foragers collecting at different reward rates.
TLDR
The results show that when foraging bees returned from a feeder delivering a higher flow rate they initiated unloading at higher thoracic temperatures and transferred the solution at higher speed and receiver bees warmed up faster in proportion to increasing forager temperature and unloading rate. Expand
Nectar production patterns in Ipomopsis aggregata (Polemoniaceae).
TLDR
How nectar production rate and sugar concentration are influenced by flower age, time of day, point in the flowering season, weather conditions and removal of nectar by pollinators and nectar robbers is described. Expand
The competition box: a graphical aid to forecasting pollinator performance
TLDR
By superimposing a bee-species-specific template on a representative nectar trajectory for a given flower species in a given situation, it is possible to make reasoned guesses about the expected interactions of foraging bee species with a novel flower species and with each other in a novel situation. Expand
Variation within and among Blueberry Taxa in Flower Size and Shape
TLDR
Large clone-to-clone variation within taxa for each flower characteristic indicates much potential for changing the shape of the blueberry flower by breeding, if the shape that maximizes fruit set can be determined. Expand
