Effect of honeybee venom and Egyptian propolis on the honeybee (Apis mellifera L.) health in vivo

Egyptian Journal of Biological Pest Control, 2022
Background Honeybees are one of the most important pollinators in the world, and their products are nowadays included in most anticancer, antiallergic, antimicrobial drugs and are included in cosmetic treatments.

Evidence for adaptive explanations of semelparity in animals

Biological Reviews, EarlyView.
ABSTRACT Semelparity, the reproductive strategy of reproducing once, is widespread but uncommon in animals. Classes of models to explain the evolution of semelparity are based either on age structure and mortality schedules – demographic models in which high post‐reproductive mortality risk favours high reproductive effort and semelparity results from ...

Effects of Artificial Sugar Supplementation on the Composition and Nutritional Potency of Honey from Apis cerana

Insects
In the global apiculture industry, reward feeding and supplementary feeding are essential for maintaining bee colonies. Beekeepers provide artificial supplements to their colonies, typically in the form of either a honey–water solution or sugar syrup ...

2D MXene‐Enabled Unidirectional Flexible Optoelectronic Memristor Toward Energy‐Efficient Neuromorphic Photosensing

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A transparent and flexible ITO/ZnO/TiO2/MXene optoelectronic memristor is developed via low‐temperature solution processing, exhibiting intrinsic self‐rectification and analog synaptic plasticity. The device enables wavelength‐selective photosynaptic response and multimodal learning behaviors, demonstrating strong potential for neuromorphic ...

Changes in Alternative Splicing in Apis Mellifera Bees Fed Apis Cerana Royal Jelly

Journal of Apicultural Science, 2014
The Western honey bee (Apis mellifera) is a social insect characterized by caste differentiation in which the queen bee and worker bees display marked differences in morphology, behavior, reproduction, and longevity despite their identical genomes.

Potential of Bee Pollen as a Nutraceutical And/Or Functional Ingredient for Metabolic Syndrome Management: In Vitro Antioxidant, Anti‐Inflammatory, and Digestive Enzyme Inhibitory Activities

Food Chemistry International, EarlyView.
Bee pollen samples from China and Spain exhibited in vitro antioxidant, anti‐inflammatory, and digestive enzyme inhibitory activities due to their composition, suggesting their potential as a nutraceutical or functional ingredient to help counteract oxidative stress, chronic inflammation, and metabolic disorders.

Absence of Nepotism in Waggle Communication of Honeybees (Apis mellifera)

Journal of Apicultural Science, 2020
The polyandrous mating behavior of the honeybee queen increases the genetic variability among her worker offspring and the workers of particular subfamilies tend to have a genetic predisposition for tasks preference.

Defining the pollinator garden: is conceptual flexibility a feature or a bug?

Frontiers in Ecology and the Environment, EarlyView.
Ecologists often aim to reduce conceptual ambiguity by attempting to create rigid shared lexicons. These efforts imply that ambiguity is undesirable. In some contexts, however, conceptual flexibility comes with under‐discussed benefits. Here, we use the lens of pollinator gardening to explore how conceptual flexibility is built into participatory ...

Acetamiprid Exposure Disrupts Gut Microbiota in Adult and Larval Worker Honeybees (Apis mellifera L.)

Insects
Acetamiprid is a third-generation neonicotinoid insecticide that is now widely employed for the protection of crops grown in outdoor environments. This is because it is considerably less toxic to pollinating insects than other neonicotinoids.

The Behaviour of Robber Honeybees [PDF]

Behaviour, 1955
1. The factors which cause the characteristic swaying flight of robber honeybees have been investigated. 2. This flight occurs as an innate response to the presence of a congestion of bees, of their own or another colony, at the entrance to the hive they are robbing. 3.
