“…Hisses were part of how colonies responded to hornet attacks in our study, but colonies also hissed under no-attack conditions. This latter finding agrees with previous studies showing that A. cerana colonies hiss without apparent provocation [80,136]. Because of their timing in this study, it is unlikely that hisses are used to deter high-threat hornet predators.…”

“…Discrete signal features help to avoid ambiguity, aligning with predictions of greater communicative complexity when species are highly social and have sophisticated predator defences [9,129,130]. While hisses are considered aposematic warning signals in many animal taxa, including bees [32,48,80,127,131–135], the role hisses play in A. cerana defence is not clear [77,80,136]. Hisses were part of how colonies responded to hornet attacks in our study, but colonies also hissed under no-attack conditions.…”

Giant hornet (Vespa soror) attacks trigger frenetic antipredator signalling in honeybee (Apis cerana) colonies

Asian honeybees use an impressive array of strategies to protect nests from hornet attacks, although little is understood about how antipredator signals coordinate defences. We compared vibroacoustic signalling and defensive responses of Apis cerana colonies that were attacked by either the group-hunting giant hornet Vespa soror or the smaller, solitary-hunting hornet Vespa velutina . Apis cerana colonies produced hisses, brief stop signals and longer pipes under hornet-free conditions. However, hornet-attack stimuli—and V. soror workers in particular—triggered dramatic increases in signalling rates within colonies. Soundscapes were cacophonous when V. soror predators were directly outside of nests, in part because of frenetic production of antipredator pipes, a previously undescribed signal. Antipredator pipes share acoustic traits with alarm shrieks, fear screams and panic calls of primates, birds and meerkats. Workers making antipredator pipes exposed their Nasonov gland, suggesting the potential for multimodal alarm signalling that warns nestmates about the presence of dangerous hornets and assembles workers for defence. Concurrent observations of nest entrances showed an increase in worker activities that support effective defences against giant hornets. Apis cerana workers flexibly employ a diverse alarm repertoire in response to attack attributes, mirroring features of sophisticated alarm calling in socially complex vertebrates.

“…Lasso logistic regression and singular value decomposition are currently available to analyse the sound of hives to identify sound patterns in queenless bee colonies (Robles-Guerrero et al, 2019). Kawakita et al (2019) recorded hive sounds of Apis cerana japonica over 24 h, and they found that Apis cerana japonica hissing had unique temporal patterns. Cejrowski et al (2020) also presented a method that uses Mel Frequency Cepstral Coe cients (MFCCs) features and an SVM classi er to de ne the start and the end of the presumed bees-night in summer.…”

Honey bees (Apis spp.) are widely used as biological indicators of environmental changes. Recently, bees have been explored by researchers to monitor air contamination by listening to their hive sound. However, no study has determined whether beehive sound reflects the responses of bees to in-hive or out-hive chemicals. In this study, we conducted a feeding experiment to address this. First, we fed colonies with pure syrup (PS), syrup containing acetone (SA) or syrup containing ethyl acetate (SE) to collect beehive sound to establish multiple classifications using machine learning (ML) models. Then, we orderly fed colonies with PS, followed by SE, SA and PS. Next, we fed colonies in PS, SA, SE and PS order. Eventually, we evaluated the recall and precision of the model in detecting each syrup type. The result built on orderly feeding had a recall of 99%, 80%, 30%, 53% in detecting PS, SE, SA, PS, respectively. In the reverse feeding experiment, the ML model has a recall of 99%, 89%, 37% and 44% in detecting PS, SA, SE, and PS, respectively. Because the collected syrup in the two orderly feeding sessions was not removed from the frames during the experiment, the results indicate that beehive sound responds to chemicals in or out of the beehive.

“…Buzzing sounds are associated with nest defense and are believed to serve to communicate with nestmates [ 25 , 29 ]. Hissing sounds are also emitted by some honeybee species [ 30 , 31 , 32 , 33 , 34 , 35 , 36 , 37 , 38 , 39 , 40 ]. As in bumblebees, hissing is believed to be primarily an aposematic alarm signal.…”

Guarding Vibrations—Axestotrigona ferruginea Produces Vibrations When Encountering Non-Nestmates

Flower visiting stingless bees store collected pollen and nectar for times of scarcity. This stored food is of high value for the colony and should be protected against con- and heterospecifics that might rob them. There should be high selective pressure on the evolution of mechanisms to discriminate nestmates from non-nestmates and to defend the nest, i.e., resources against intruders. Multimodal communication systems, i.e., a communication system that includes more than one sensory modality and provide redundant information, should be more reliable than unimodal systems. Besides olfactory signals, vibrational signals could be used to alert nestmates. This study tests the hypothesis that the vibrational communication mode plays a role in nest defense and nestmate recognition of Axestotrigona ferruginea. Substrate vibrations induced by bees were measured at different positions of the nest. The experiments show that guarding vibrations produced in the entrance differ in their temporal structure from foraging vibrations produced inside the nest. We show that guarding vibrations are produced during non-nestmate encounters rather than nestmate encounters. This further supports the idea that guarding vibrations are a component of nest defense and alarm communication. We discuss to whom the vibrations are addressed, and what their message and meaning are.
