Pollen foraging: learning a complex motor skill by bumblebees (Bombus terrestris)

  title={Pollen foraging: learning a complex motor skill by bumblebees (Bombus terrestris)},
  author={Nigel E. Raine and Lars Chittka},
To investigate how bumblebees (Bombus terrestris) learn the complex motor skills involved in pollen foraging, we observed naïve workers foraging on arrays of nectarless poppy flowers (Papaver rhoeas) in a greenhouse. Foraging skills were quantified by measuring the pollen load collected during each foraging bout and relating this to the number of flowers visited and bout duration on two consecutive days. The pollen standing crop (PSC) in each flower decreased drastically from 0530 to 0900 hours… 
Foraging errors play a role in resource exploration by bumble bees (Bombus terrrestris)
It is demonstrated that the time taken to discover the novel, more profitable, food source is positively correlated with foraging success and suggested that foraging errors are part of an ‘exploration’ foraging strategy, which could be advantageous in changeable foraging environments.
Individual lifetime pollen and nectar foraging preferences in bumble bees
Monitoring all foraging visits made by every bee in multiple colonies showed that individual foragers exhibit consistent lifetime foraging preferences, and suggested that generalists can alter their foraging preference in response to the loss of a small subset of foragers.
Floral Sonication is an Innate Behaviour in Bumblebees that can be Fine-Tuned with Experience in Manipulating Flowers
Investigation of the ability of the buff-tailed bumblebee (Bombus terrestris) to modify the frequency and amplitude of their buzzes with increasing experience manipulating flowers of the buzz-pollinated plant Solanum rostratum suggests that bumblebees are able to modified the characteristics of their Buzzes with experience manipulating buzz- pollinated flowers.
Bumble bee pollen foraging regulation: role of pollen quality, storage levels, and odor
Pollen stores can act as an information center regulating colony-level foraging according to pollen protein quality and colony need and are tuned to the protein quality of pollen collected by foragers and to the amount of stored pollen inside the colony.
Foraging Economics of the Hunt Bumble Bee, a Viable Pollinator for Commercial Agriculture
This study provides data on how long it takes for B. huntii to forage in open field conditions and will be useful when comparing foraging rates in controlled crop systems.
Bumble bees exhibit daily behavioral patterns in pollen foraging
This work developed a highly controlled mechanistic framework to measure pollen foraging preferences of the bumble bee Bombus impatiens to nine plant species native to Pennsylvania, and demonstrates that B. impatisens exhibit predictable daily patterns in their pollen foraged choices, and their preferences are dominated by the host-plants they visit first.
Manuscript in preparation for Behavioral Ecology and Sociobiology Bumble bee pollen foraging regulation: role of pollen quality, storage levels, and odor
Evidence is presented that pollen stores can act as an information center regulating colony-level foraging according to pollen protein quality and colony need and that bumble bee colony foraging levels and pollen storage behavior are tuned to the protein quality of pollen collected by foragers and to the amount of stored pollen inside the colony.
Effects of Experience on Short- and Long-term Foraging Performance in Bumblebees
Bumblebees foraging on pepper plants inside a greenhouse suggests that a variety of flower-handling tasks, flower choice and movements between plants can be learned quickly under the simple greenhouse settings.
Onset of morning activity in bumblebee foragers under natural low light conditions
Bumblebee colonies have the potential to balance the benefits of deploying large‐sized or experienced foragers during dawn against the risks and costs of foraging under low light by regulating the onset of their activity at different stages of the colony's life cycle and in changing environmental conditions.
Divergent Rules for Pollen and Nectar Foraging Bumblebees – A Laboratory Study with Artificial Flowers Offering Diluted Nectar Substitute and Pollen Surrogate
It is shown that bumblebee (Bombus terrestris) workers do not specialise in nectar or pollen collection, but regularly collect both rewards on the same day, and how the bumblebees' ability to sense sugar, and their apparent inability to sense the pollen protein content, shaped their foraging behaviour is discussed.


Behavioral responses by bumble bees to variation in pollen availability
Simulation results indicate that the observed movement patterns of bumble bees on Lupinus inflorescences would return the most pollen per unit of expended energy, and the increased foraging efficiency resulting from facultative responses by bees to variation in pollen availability, especially changes in the frequency and intensity of grooming, could correspondingly decrease pollen dispersal between plants.
Overnight memory retention of foraging skills by bumblebees is imperfect
The results indicate that bees learn to approach and probe flowers faster, as they gain experience, during a foraging day, but that these skills are partially forgotten overnight.
Foraging dynamics of bumble bees: correlates of movements within and between plant species
It is concluded that the bees' choices were determined by a set of rules that guided them to stay with the current plant species as long as flowers were rewarding and available within close distance but to switch to another species if flowers offered low rewards or were not encountered at close range.
The foraging behavior of bumblebees is discussed from a comparative standpoint with other bees and in relation to food distribution and availability in the environment.
Bumble bee learning and flower morphology
In general, morphologically complex flower designs took bees longer to learn than open-tubed or cup-shaped designs, however, specific predictions about the relative difficulty of learning to handle flowers could not be made from general flower morphology.
The specialist bee, Hoplitis anthocopoides, foraged for pollen from Echium vulgare, its preferred plant, more efficiently than did four generalist species and supports the assumption in models of resource partitioning and optimal foraging theory and in hypotheses explaining the evolution of pollen-specializing bee species, that specialists are more efficient at using their preferred resources.
Sensori-motor learning and its relevance for task specialization in bumble bees
While bees would become proficient at two tasks more quickly if their acquisition phase included switches, such switches had no measurable effect in the saturation phase, and the implications of these findings for foraging are discussed using modern learning theory.
Sensorimotor learning in bumblebees: long-term retention and reversal training
The results suggest that sensorimotor information is rarely lost from long-term memory, either during extended lay-offs or during interfering reversal training sessions, which indicates that bees can learn actively to suppress irrelevant information, but only with an extended training schedule.
Bees, like their wasp relatives, forage for and transport food to a nest as provisions for their offspring. Unlike female Sphecoidea which transport arthropods one at a time as prey, bees transport

In tristylous Pontederia cordata (Pontederiaceae), conspicuous differences in the size of pollen grains and discrete variation in the length of reproductive organs provide a suitable experimental
