Apis mellifera
- Honeybees fail to discriminate floral scents in a complex learning task after consuming a neonicotinoid pesticide
Summary: Honeybees exposed to the neonicotinoid pesticide thiamethoxam cannot perform a complex learning task. Honeybees exposed to other neonicotinoids such as imidacloprid and clothianidin, can learn this task, but at a slower rate.
- Honey bee caste lipidomics in relation to life-history stage and the long life of the queen
Summary: The extraordinary difference in lifespan between honey bee castes may be partially explained by oxidative damage as a result of the diet-induced increase in membrane polyunsaturated fatty acids in workers.
- Honeybees generalize among pollen scents from plants flowering in the same seasonal period
Summary: The proboscis extension response of honey bees was conditioned using different pollen scents, then tested with novel pollen scents. Honey bees generalized the pollen scents from plants that share the same flowering period.
- Exosome-like vesicles in Apis mellifera bee pollen, honey and royal jelly contribute to their antibacterial and pro-regenerative activity
Summary: Apis mellifera honeybee hypopharyngeal gland secretions contain exosome-like vesicles, which contribute to their antibacterial and pro-regenerative activity.
- Honey bees flexibly use two navigational memories when updating dance distance information
Summary: Individual honey bees flexibly use recently acquired navigation experience and previously stored navigation information to generate waggle dance duration for a novel feeder distance.
- A new, practicable and economical cage design for experimental studies on small honey bee colonies
Summary: A new, practicable, low-cost cage system for effectively housing small bee colonies to enable investigation of physical conditions, biological factors and environmental contaminants on honey bee responses.
- High experience levels delay recruitment but promote simultaneous time-memories in honey bee foragers
Summary: High experience levels at one food source delay recruitment to another food source at the same time of day but, nevertheless, promote simultaneous time-memories in honey bee foragers.
- Reanalysis of an oft-cited paper on honeybee magnetoreception reveals random behavior
Summary: Re-creation of the results of a well-cited study on honeybee magnetoreception using a random number generator demonstrates that the conclusions of the original paper were due to incorrect data analyses.
- Visual discrimination transfer and modulation by biogenic amines in honeybees
Summary: Honeybees can transfer visual information from a classical to an operant context and appetitive visual learning in honeybees is modulated by octopamine and dopamine.
- Impaired associative learning after chronic exposure to pesticides in young adult honey bees
Highlighted Article: Imidacloprid and glyphosate affect gustatory responsiveness and learning in young honey bees, which show differential sensitivity according to their age, making them successful models for studying pesticide effect on physiology and behaviour.
