Honey bees show dance pattern to communicate – A review

The honey bee language is considered by many to be one of the most interesting systems for animal communications, used for recruitment to food sources. Honeybee's forager dancers communicate food and other resources to the household by quantity, consistency, direction, and spatial location. The waggle dance was interesting and complex, which bees used for spatial information on desired resources. All honeybee species use the waggle dance to convey their position and distance from food sources and possible new nest sites. The research was carried out on dance communication, earlier ideas, controversies, and solutions gave a broad overview. In this analysis, unique problems are focused on as follows: (a) multiple dance forms. (b) Distance and path calculation (c) How bees do dark hive dance.? Several experiments verified that bees perform various kinds of dance, depending on their particular task. There is, however, still a lack of comprehensive knowledge on other types of dances, which help us solve numerous questions and help us better understand the meaning of the different kinds of dances carried in and outside the hive by honeybees.

Parallel processing of olfactory and mechanosensory information in the honeybee antennal lobe.

We report that airflow produces a complex activation pattern in the antennal lobes of the honeybee Apis mellifera. Glomerular response maps provide a stereotypical code for the intensity and the dynamics of mechanical stimuli that is superimposed on the olfactory code. We show responses to modulated stimuli suggesting that this combinatorial code could provide information about the intensity, direction, and dynamics of the airflow during flight and waggle dance communication.

Einstein, von Frisch and the honeybee: a historical letter comes to light

The work of the Nobel Laureate Karl von Frisch, the founder of this journal, was seminal in many ways. He established the honeybee as a key animal model for experimental behavioural studies on sensory perception, learning and memory, and first correctly interpreted its famous dance communication. Here, we report on a previously unknown letter by the Physicist and Nobel Laureate Albert Einstein that was written in October 1949. It briefly addresses the work of von Frisch and also queries how understanding animal perception and navigation may lead to innovations in physics. We discuss records proving that Einstein and von Frisch met in April 1949 when von Frisch visited the USA to present a lecture on bees at Princeton University. In the historical context of Einstein’s theories and thought experiments, we discuss some more recent discoveries of animal sensory capabilities alien to us humans and potentially valuable for bio-inspired design improvements. We also address the orientation of animals like migratory birds mentioned by Einstein 70 years ago, which pushes the boundaries of our understanding nature, both its biology and physics.

Absence of Nepotism in Waggle Communication of Honeybees (Apis mellifera)

The polyandrous mating behavior of the honeybee queen increases the genetic variability among her worker offspring and the workers of particular subfamilies tend to have a genetic predisposition for tasks preference. In this study, we intended to understand whether there is nepotism in dance communication of honeybees during natural conditions. Microsatellite DNA analyses revealed a total of fourteen and twelve subfamilies in two colonies. The subfamily composition of the dancer and the followers did not deviate from random. The majority of the subfamilies did not show kin recognition in dance-recruit communication in honeybee colonies, but some subfamilies showed significant nepotism for workers to follow their super-sister dancer. Because it seems unlikely that honeybee would change the tendency to follow dancers due to the degree of relatedness, we conclude that honeybees randomly follow a dancer in order to e benefit colony gain and development.

Circadian plasticity in honey bees

Circadian rhythms of about a day are ubiquitous in animals and considered functionally significant. Honey bees show remarkable circadian plasticity that is related to the complex social organization of their societies. Forager bees show robust circadian rhythms that support time-compensated sun-compass navigation, dance communication and timing visits to flowers. Nest-dwelling nurse bees care for the young brood around the clock. Here, we review our current understanding of the molecular and neuroanatomical mechanisms underlying this remarkable natural plasticity in circadian rhythms.

Similarities in the behaviour of dance followers among honey bee species suggest a conserved mechanism of dance communication

Group living organisms rely on intra-group communication to adjust individual and collective behavioural decisions. Complex communication systems are predominantly multimodal and combine modulatory and information bearing signals. The honey bee waggle dance, one of the most elaborate forms of communication in invertebrates, stimulates nestmates to search for food and communicates symbolic information about the location of the food source. Previous studies on the dance behaviour in diverse honey bee species demonstrated distinct differences in the combination of visual, auditory, olfactory, and tactile signals produced by the dancer. We now studied the behaviour of the receivers of the dance signals, the dance followers, to explore the significance of the different signals in the communication process. In particular, we ask whether there are differences in the behaviour of dance followers between the 3 major Asian honey bee species, A. florea, A. dorsata and A. cerana, and whether these might correlate with the differences in the signals produced by the dancing foragers. Our comparison demonstrates that the behaviour of the dance followers is highly conserved across all 3 species despite the differences in the dance signals. The highest number of followers was present lateral to the dancer throughout the waggle run, and the mean body orientation of the dance followers with respect to the waggle dancer was close to 90° throughout the run for all 3 species. These findings suggest that dance communication might be more conserved than implied by the differences in the signals produced by the dancer. Along with studies in A. mellifera, our results indicate that all honey bee species rely on tactile contacts between the dancer and follower to communicate spatial information. The cues and signals that differ between the species may be involved in attracting the followers towards the dancer in the different nest environments.
