    Notes: Summary Airborne sound signals emitted by dancing bees (Apis mellifera) play an essential role in the bees' dance communication. It has been shown earlier that bees can learn to respond to airborne sounds in an aversive conditioning paradigm. Here we present a new training paradigm. A Y-choice situation was used to determine the frequency range and amplitude thresholds of hearing in bees. In addition, spontaneous reactions of bees to airborne sound were observed and used to determine thresholds of hearing. Both methods revealed that bees are able to detect sound frequencies up to about 500 Hz. The hearing threshold is 100–300 mm/s peak-to-peak velocity and is roughly constant over the range of detectable frequencies. The amplitude of the signals emitted in the dance language is 5 to 10 times higher, so we can conclude that bees can easily detect the dance sounds.

    Notes: Summary The behaviour of young honeybee queens and of worker bees was studied in an observation hive. Tooting and quacking signals emitted by the queens were recorded as airborne sound and as substrate vibrations of the combs by means of a microphone and a laser vibrometer, respectively. The fundamental frequency component is larger than the harmonics when the signals are measured as vibration velocity, and it is argued that the signals are carried mainly by the fundamental frequency component. The frequencies emitted depend on the queens' age, and the tooting syllables contain a frequency sweep. These observations may explain some of the very diverse frequency values reported in the literature. The fundamental carrier frequencies of the toots and quacks overlap, but the tooting syllables have longer rise times than the quacking syllables. Recordings of the vibration of cells in which queens were confined allowed us to measure the threshold for the release of quacking in the confined queens by artificial toots and by natural toots from emerged queens. Artificial toots with long syllable rise time are more efficient in releasing quacking responses than are toots with short syllable rise time. This observation may suggest that the bees recognize these signals mainly by their temporal structure. A comparison of the threshold, emission level, and attenuation with distance, suggests that these and other vibration signals are used by honey bees only for local communication within a restricted area of the comb.

    The acoustic near field of a dancing honeybee (1987)

    Notes: Summary The acoustic near field close to honeybees performing the wagging dance was investigated with pairs of small, matched microphones placed in various positions around the dancing bees. The dance ‘sounds’ are produced by the wings, which act as an asymmetrical dipole emitter. Close to the abdomen, the ‘sound’ pressures in the air spaces above and below the plane of the wings are totally out of phase. A zone of very intense acoustical short-circuiting exists close to the edges of the wings, where pressure gradients of about 1 Pa/mm are observed in the dorso-ventral direction (perpendicular to the plane of the wings). The pressure gradients drive air movements with velocity amplitudes up to about 1 m/s. The pressure gradients are much smaller in directions radially away from the bee and decrease rapidly with increasing distance from the wings. The ‘sound’ pressure detected by a stationary probe at one side of the bee is strongly modulated at 12–13 Hz as a result of the bee's side-to-side wagging. Surprisingly little ‘sound’ is found near the dancer's head. The positions of the follower bees reflect the properties of the acoustic field: The follower bees place their antennae in the zone of maximum acoustical short-circuiting where the air particle movements are most intense. These observations suggest 1) how follower bees can avoid mixing up the messages carried by the dance ‘sounds’ when two or more bees are dancing only a few cm apart and 2) how the followers might extract information about a dancer's spatial orientation from the acoustic near field she produces. The observations also provide clues regarding the nature of the putative ‘sound’ receivers.

    Notes: Abstract Although several independent lines of evidence show that bees can make use of information provided by their dance language, there is an ongoing controversy about the significance of the dance information versus odor cues in the search behavior of recruited bees. A series of experiments was performed to assess the relative significance of dance information and odors for the site-specific search of recruit bees. In these experiments recruit bees were trapped automatically at arrays of artificial flowers at various distances from the hive. The distribution of directions in which the recruits searched for food was compared between recruitment by dancers performing well-oriented dances on the vertical side of the comb and dancers performing disoriented dances on a horizontal comb. The results show quantitatively that bees use both odor cues and the dance information. The greater the distance to the feeding site, the greater is the relative significance of the dance information.

    The dance language of the honeybee mutant diminutive wings (1992)
    Springer
    Behavioral ecology and sociobiology 30 (1992), S. 181-184

    Notes: Summary The dance communication of honeybees was studied using the short-winged mutant diminutive wings. The wing area of the mutant is reduced to 67% that of the wild type. This reduction in wing area leads to increases in both the wing beat frequency and the frequency of the sounds emitted during the dances. At the same time the amplitude of the sound signals is reduced. These changes have a strong effect on the recruitment success of the dances, which is reduced to less than 50%. Thus, the acoustical signals emitted by dancing bees play an essential role in the bees' dance communication.

    How honeybees perceive communication dances, studied by means of a mechanical model (1992)

    Notes: Summary A mechanical model of a dancing honeybee was used to investigate the role of various components of the wagging dance in the transfer of information to follower bees. The model simulates the dance, carries a scent, and has an acoustic near-field similar to that of live dancers. The movements of the model are controlled by a computer, and selected components of the dance can be manipulated independently of others. The number of bees approaching scented baits at various distances and directions from the hive was observed, both during simulated “normal” dances and dances in which different components provided potentially conflicting information about the location of the food. The results indicate that the wagging run is the “master component” of the dance. The figure-of-eight dance path does not seem to convey information. Both sound and wagging must be present in the dance, but no specific roles were found for these components. Both sound and wagging convey information about distance and direction, and they appear to be largely redundant.

    Acoustical signals in the dance language of the giant honeybee, Apis dorsata (1993)

    Notes: Summary Acoustical signals emitted by dancing bees have recently been shown to transmit information about the location of food sources in the western honeybee, Apis mellifera. Towne (1985) reported that in the Asian honeybee species Apis dorsata, which builds a single comb in the open under overhanging rocks or tree branches, sound signals were not emitted by the dancers. This led to the conclusion that acoustical communication is restricted to bees that nest in the dark, like A. mellifera. Here we show that in fact A. dorsata produces dance sounds similar to those emitted by A. mellifera, and that these acoustical signals contain information about distance, direction and profitability of food sources. The acoustical transfer of information has thus evolved independently of nesting in dark cavities. The significance of nocturnal activity in Apis dorsata for the evolution of sound communication is discussed.

    Sound and vibrational signals in the dance language of the honeybee, Apis mellifera (1986)

    Notes: Summary Sound and vibrational signals exchanged by honeybees during the performance of wagging dances were simultaneously recorded by means of a microphone and a laser vibrometer. Previous descriptions of the 280-Hz sounds emitted by the dancing bee were confirmed, and no vibrational (substrate-borne) component could be detected. In contrast, the 320-Hz “begging signals” (emitted by bees following a dancer and used as a request for food samples from the dancer) do vibrate the comb with peak-peak displacement amplitudes up to 1.5 μm. Artificially-generated comb vibrations of sufficient amplitude cause bees standing on the comb to “freeze”. The threshold for obtaining a detectable freezing response was measured for frequencies between 100 Hz and 3 kHz. At 320 Hz it is just below the amplitude of the natural begging signals. Thus it seems likely that these signals are received by the bees as vibrations of the comb. The propagation velocity of waves, damping, and mechanical input impedance of honeybee combs were studied. These results, combined with the observed amplitudes of the begging signals, support the assumption that the begging signals are generated with the flight muscles. The begging signal propagates as a bending wave. The attenuation of the begging signal with distance is relatively small, so the amplitude of the signal probably needs to be carefully adjusted in order to restrict the range of the communication.

    The causes of the tremble dance of the honeybee, Apis mellifera (1994)

    Notes: Abstract Tremble dances are sometimes performed by returning forager bees instead of waggle dances. Recent studies by Seeley (1992) and Kirchner (1993) have revealed that this behaviour is part of the recruitment communication system of bees. The ultimate cause of tremble dances is, according to Seeley (1992), an imbalance between the nectar intake rate and the nectar processing capacity of the colony. This imbalance is correlated with a long initial search time of returning foragers to find bees to unload them. However, it remained unclear whether a long search time is the direct proximate cause of tremble dancing. Here we report that a variety of experimental conditions can elicit tremble dances. All of them have in common that the total search time that foragers spend searching for unloaders, until they are fully unloaded, is prolonged. This finding supports and extends the hypothesis that a long search time is the proximate cause of tremble dancing. The results also confirm the previous reports of Lindauer (1948) and others about factors eliciting tremble dancing.
