Food alert in bumblebees (Bombus terrestris): possible mechanisms and evolutionary implications

Abstract. The return of a successful bumblebee forager stimulates nestmates to leave the nest and search for food. Here we investigate the mechanisms by which this happens. Successful Bombus terrestris foragers perform irregular runs in their nest, often lasting for several minutes. Run duration is at its maximum when food has just been discovered. Running likely serves to distribute a pheromone, since the information flow between "runners" and "recruits" can be disrupted by eliminating air… Expand

Figures from this paper

Bumble bees (Bombus terrestris) store both food and information in honeypots
It is shown here that bees in the nest continuously monitor honeypots and sample their contents, thus obtaining information on supply and demand of nectar, and that the readiness of bees to respond to recruitment signals or incoming nectar also depends on colony demand. Expand
Chemical compounds of the foraging recruitment pheromone in bumblebees
The presence of two monoterpenes and one sesquiterpene (eucalyptol, ocimene and farnesol) in the nest airspace and in the tergal glands increases strongly during foraging, which suggests independent evolutionary roots of food recruitment in these two groups of bees. Expand
Information flow and regulation of foraging activity in bumble bees (Bombus spp.)
Information exchange in the nest enables bumble bees to base their decision to forage on demand and the presence and profitability of food, and allows them to learn the scent of food sources at the nest, which may reduce their search time. Expand
Foraging distance in Bombus terrestris L. (Hymenoptera: Apidae)
The spatial distribution and the quality of forage plots are found to be the major determinants for the bees foraging decision-making, explaining over 80% of the foraging frequency. Expand
Colony and Individual Forager Responses to Food Quality in the New World Bumble Bee, Bombus occidentalis
Testing the ability of the species, Bombus occidentalis, to stimulate colony foraging for food varying in quality and the behavior of successful foragers inside the nest to learn more about potential foraging activation movements found it to be positively correlated with food sucrose concentration. Expand
Chemical ecology of bumble bees.
The development of new and more sensitive analytical tools and improvements in sociogenetic methods significantly enhanced knowledge about chemical compounds that mediate the regulation of reproduction in the social phase of colony development, about the interactions between host bumble bees and their social parasites, about pheromones involved in mating behavior, as well as about the importance of signals, cues and context-dependent learning in foraging behavior. Expand
Bumble bees alert to food with pheromone from tergal gland
It is shown that a hexane extract from tergites V–VII of bumble bee workers elicits higher activity, like a successful forager does, which suggests that bumble bees possess a pheromone-producing gland, similar to the Nasanov gland in honey bees. Expand
How floral odours are learned inside the bumblebee (Bombus terrestris) nest
It was found that releasing floral scent in the air of the colony was sufficient to trigger learning and that learning performance was improved when the chemosensory cue was provided in the nectar in honeypots; probably because it guarantees a tighter link between scent and reward, and possibly because gustatory cues are involved in addition to olfaction. Expand
Potential application of the bumblebee foraging recruitment pheromone for commercial greenhouse pollination
It is concluded that artificial recruitment pheromone can reliably boost bee traffic leaving previously inactive colonies and could improve foraging activity and pollination in greenhouse colonies. Expand
Honeypot visitation enables scent learning and heightens forager response in bumblebees (Bombus impatiens)
Bumblebees integrate cues associated with food that they experience within their nest. Both experienced and naive workers rely on odours in the nectar collected by foragers and stored in honeypots toExpand


Insect behaviour: Evolutionary origins of bee dances
New light is shed on the early evolutionary origins of the elaborate dance language of the honeybee by showing that bumble-bee communication uses a primitive, but surprisingly efficient, recruitment system. Expand
Social Wasp (Hymenoptera: Vespidae) Foraging Behavior
A forager’s ability to learn odors and landmarks, which direct its return to foraging sites, and to associate cues such as odor or leaf damage with resource availability provide the behavioral foundation for facultative specialization by individual foragers. Expand

There is no careful description of within-nest recruitment behavior for this species or for any other stingless bee, so this paper is to provide a detailed description of the behaviors of recruiting M. panamica foragers within the nest. Expand
Navigation without vision: bumblebee orientation in complete darkness
In flight cages, worker bumblebees (Bombus impatiens) spontaneously explored the surroundings of their nest and foraged in complete darkness, by walking instead of flying, from feeders up to 150 cmExpand
Repellent scent-marking of flowers by a guild of foraging bumblebees (Bombus spp.)
It is found that flowers were repellent to other bumblebee foragers for approximately 20 min and also that after this time nectar levels in S. officinale flowers had largely replenished, Thus bumblebees could forage more efficiently by avoiding flowers with low rewards. Expand

The results presented here reveal that the nature of the floor on which the bees dance has a considerable influence on the recruitment of nestmates to a food source. Expand

Phylogenetic analyses of DNA sequence information from the mitochondrial genome of representative apid bees suggest that advanced eusocial behavior evolved twice independently within this assemblage. Expand
Sound: An Element Common to Communication of Stingless Bees and to Dances of the Honey Bee
The social organization of communities of stingless bees is more primitive than that of honey bees, yet certain common features of communication behavior in these two groups lead to a new hypothesis of the evolution of dancing behavior of the honey bee. Expand
What attracts honeybees to a waggle dancer?
Abstract In the vicinity of a dancer, a honeybee can become a dance follower after touching the dancer or a dance follower with an antenna. If the attraction occurs without such antennal contact, theExpand
