Honey bees (genus Apis) are well known for the impressive suite of nest defenses they have evolved to protect their abundant stockpiles of food and the large colonies they sustain. In Asia, honey bees have evolved under tremendous predatory pressure from social wasps in the genus Vespa, the most formidable of which are the giant hornets that attack colonies in groups, kill adult defenders, and prey on brood. We document for the first time an extraordinary collective defense used by Apis cerana…

Hornets and Honey Bees: A Coevolutionary Arms Race between Ancient Adaptations and New Invasive Threats

A comprehensive review of the existing studies that have investigated the interactions between hornets and honey bees throughout the world is provided, highlighting the complexity of the specialized strategies adopted by Asian honey bees and their sympatric predators and the relative lack of coevolution and effective defenses of Western honey bees against invasive hornets.

Linking the Morphology of Sternal Glands to Rubbing Behavior by Vespa soror (Hymenoptera: Vespidae) Workers During Recruitment for Group Predation

The morphology of the sternal glands of the giant hornet Vespa soror du Buysson are described and their potential to contribute to a marking pheromone is considered and insight is provided into the use of exocrine secretions by giant hornets as they recruit nestmates to prey colonies for group attacks.

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

Comparison of the External Morphology of the Sternal Glands for Hornets in the Genus Vespa

The external morphology associated with both glands for workers of nine Vespa species using scanning electron microscopy was characterized, finding that giant hornets and their close relatives had comparatively larger glands than the other species, some of which had glands that were approximately half as large.

Olfactory Strategies in the Defensive Behaviour of Insects

How insects use smell to detect threats and perform behaviours of ‘flight or fight’ such as avoidance, escape or attack, in order to protect themselves, and how chemical signals such as the alarm pheromone are processed in the insect brain are reviewed.

Risk Assessment for the Establishment of Vespa mandarinia (Hymenoptera: Vespidae) in the Pacific Northwest, United States

By design, the tier-1 risk assessment most likely overestimates the risk of establishment of V. mandarinia in Washington, Oregon, Montana, and Idaho, but considering its negative effects, these counties should be prioritized in ongoing monitoring and eradication efforts.

Peripheral taste detection in honey bees: What do taste receptors respond to?

An evolutionary and comparative perspective is adopted to understand the neural principles of honey bee taste and define key questions that should be answered in future gustatory research centered on this insect.

Defensive shimmering responses in Apis dorsata are triggered by dark stimuli moving against a bright background

It is suggested that this is an effective anti-predatory strategy in open-nesting A. dorsata colonies which are exposed to high ambient light, as flying predators are more easily detected when they appear as dark moving objects against a bright sky.

An easy, effective and cheap method of the European hornets eradication

A cheap, versatile and effective method of hornets elimination based on the contact of flying individuals with the 20-30% solution of NaOH is reported. Importantly, the insects survived from the

Extending the Reach of Tooling Theory: A Neurocognitive and Phylogenetic Perspective

It is suggested that the adoption of Fragaszy and Mangalam's (2018) tooling framework, which is characterized by the creation of a body-plus-object system that manages a mechanical interface between tool and surface, should be adopted.



Behavioral responses of honey bees, Apis cerana and Apis mellifera, to Vespa mandarinia marking and alarm pheromones

The marked differences in responses of the two honey bee species suggest that Asian honey bees are able to alter their behavior in response to one of their major predators while honey bees that are not exposed to this predator do not.

Agonistic interactions between the honeybee (Apis mellifera ligustica) and the European wasp (Vespula germanica) reveal context-dependent defense strategies

It is found that agonistic events supported by other nestmates were typically the most intense ones, involving physical combat and prolonged attacks at the entrance to the hive, supporting the hypothesis that A. mellifera ligustica can adapt its behavior to match the severity of the threat and the context of the attack.

Colony Defense Strategies of the Honeybees in Thailand

Each species' colony defense system consists of numerous interwoven lines of adaptation, including nest site, nest architecture, colony population, labor allocation to defense, age polyethism schedule, colony mobility, and worker morphology, physiology, and behavior.

Unusual thermal defence by a honeybee against mass attack by hornets

THE giant hornet Vespa mandarinia japonica (Hymenoptera: Vespidae) is the only hornet species known to have evolved en masse predation of other social bees and wasps. Here we show that hornets is

Defence reactions of Apis mellifera ligustica against attacks from the European hornet Vespa crabro

Comparing the differences and similarities of this behaviour with those observed in other species of Apis and Vespa reveals that these two species are an interesting model for the study of the evolutionary arms race.

Defensive behavior of honey bees: organization, genetics, and comparisons with other bees.

Comparisons between A. mellifera and other species of Apis, as well as with allodapine, halictine, bombine, and meliponine bees, illustrate the wide variety of evolutionary solutions to problems in colony defense in the Apoidea.

Foraging on some nonfloral resources by stingless bees (Hymenoptera, Meliponini) in a Caatinga region.

The variety and intriguing abundance of bees in nonfloral resources suggests that these are an important part of the stingless bee niches, even if these resources are used for nest construction and defense.

A colony defence difference between two honey bee subspecies (Apis mellifera cypria and Apis mellifera caucasica)

Summary Colony defence differences between two honey bee subspecies Apis mellifera cypria and A. m. caucasica are reported. A. m. cypria formed significantly (P < 0.001) more defensive balls of bees
