Anatomy of a Bee
Honey bee stingers have this characteristic that causes the stinger to become lodged in the target and sever from the bee’s abdomen. When this occurs, alarm pheromones are released by the bee, helping other bees orient to the place of attack.
What is barbed?
Some compounds in alarm pheromones do not appear to elicit behavioral responses when presented alone to bees. These compounds likely play this role in the pheromone.
What is a carrier?
Stressed bees release alarm pheromones that might smell like this to the human nose.
What are bananas?
This insect is an ambushing predator. One or two individuals will ambush a bee, causing the release of alarm pheromones which act as a signal to other nearby predators to help catch the prey.
What is an ant?
Pheromones are referred to as this type of signal due to the fact that they are a reflection of an organism’s quality, status, and/or condition. Further, these signals are difficult to fake.
What are honest signals?
In bees, organs related to this function are capable of producing alarm pheromones.
What are fighting organs (mandibles and stingers used in stinging and biting)?
Several plant species have been found to produce benzyl acetate. This is a main compound in the alarm pheromones of the Asian honey bee (A. Cerana) and other bees. It is speculated that plants produce benzyl acetate for this purpose.
What is to attract pollinators?
Bees with this job in the colony are specially equipped to produce alarm pheromones. This type of bee produces alarm pheromones when there is a perceived danger, causing the recruitment of nest mates.
What are guard bees?
Bees give the I-see-you-signal to hornets outside the nest to dissuade these predators from entering the nest. This signal is given using this special behavior.
What is the abdomen shaking behavior?
When a nest mate is exposed to an alarm pheromone, they will enter this heightened state which prepares these bees to defend the colony.
What is an alert state or an aggressive state?
The Koshevnikov gland produces alarm pheromones during defensive behaviors. This gland is associated with this anatomical part of the bee.
What is the sting apparatus or stinger?
In Apis mellifera, 1-hexanol, octyl acetate, butyl acetate, 1-butanol, 1-octanol, hexyl acetate, and 2-nonanol alarm pheromones do not trigger stinging. Instead, these pheromones cause nest mates to do what?
What is recruitment of nest mates to join the defense activity?
To protect the colony from an intruding Vespa velutina hornet, bees will perform this behavior to kill the intruder. Alarm pheromones are released from both the bees and the hornet during this process.
What is forming a heat ball that bakes and smothers the intruder?
Research has shown that several hive parasites have the capability of detecting bee alarm pheromones. This parasite, specifically, was attracted to the Isopentyl acetate compound present in bee alarm pheromones.
What is the small hive beetle?
To attract predators for pollination, plants may release compounds such as octadecan-1-ol, eicosan-1-ol, and (Z)-11-eicosen-1-ol. Bees have not been found to produce these compounds. Therefore, these plants are using this strategy to attract pollinators that are predators of bees.
What is mimicking the compounds used in bee alarm cues?
In the Apis genus, this gland and the Koshevnikov gland are the main alarm pheromone producing organs. This gland can produce alarm pheromones and forage-marking pheromones.
What is the Mandibular gland?
The alarm pheromone, 2-heptanone, has not shown an effect on guard bees. This is the most probable function of this pheromone.
What is forage-marking?
Bees often change their behaviors depending on the context. If a reward is combined with an alarm pheromone, a foraging bee may respond to the cue in this way (contrary to what may be expected).
What is attraction to the cue?
Wax moths are a frequent pest of bee hives. This moth can detect bee alarm pheromones but has not been shown to avoid them. This is because wax moths are unlikely to be attacked by guard bees for this reason.
What is invading bee colonies at night?
Pheromones are an important driving factor of this evolutionary phenomenon in plant-pollinator-predator interactions.
What is co-evolution?
When a hornet finds a nest, they leave this from their van der Vecht gland. Honeybees can find this and try to remove it.
What is a marking chemical?
This was the first alarm pheromone compound identified and associated with stinging in bees. It is also associated with recruitment and repelling foraging activity. This compound can be produced by most honey bee species.
What is Isopentyl acetate?
To help conspecific mates, bees may leave this type of pheromone on a plant. Leaving this pheromone will help a mate find quality food sources.
What is a trail pheromone or a marking pheromone?
Neocypholaelaps indica (phoretic mites) will infest these locations to increase the likelihood of encountering A. cerana bees. The mites likely find these locations and A. cerana using bee alarm pheromones.
What are flowers or inflorescences?
Pheromones are a blend composed of various chemical components. These components can each cause different defensive behaviors in bees including alarming, recruitment, and this third behavior associated with bee movement.
What is flight activity or trajectory?
