HONEYBEE VIRUSES PRESENCE IN SERBIAN APIARIES: A REVIEW

open access: yesArchives of Veterinary Medicine, 2021
The honey bee Apis mellifera is an important beneficial insect recognized by production of honeybee products, having an important role in agricultural production through pollination, and play an equally crucial role in conserving the biodiversity in ...

Review of the methods to determine the hazard and toxicity of pesticides to bumblebees [PDF]

open access: yes, 2001
Methods to determine the impact of pesticides on bumblebees are described. They are classified into laboratory tests to determine the acute toxicity and the hazard to bumblebees, (semi) field tests, and brood tests.

Robustness of the honeybee neuro-muscular octopaminergic system in the face of cold stress

open access: yesFrontiers in Physiology, 2022
In recent decades, our planet has undergone dramatic environmental changes resulting in the loss of numerous species. This contrasts with species that can adapt quickly to rapidly changing ambient conditions, which require physiological plasticity and ...

Evidence that no liquid equilibrium process is involved in the comb building of honey bees (Apis Mellifera) [PDF]

open access: yes, 2017
According to Pirk et al. (2004), honeybees first build free standing cylindrical cells which are then transformed to hexagonal cross-section by wax-flow in a kind of self-organization. We show that there is no self-organization of the wax.

Numerical cognition in honeybees enables addition and subtraction

open access: yesScience Advances, 2019
Honeybees learn to add or subtract one item from a set using color cues and can interpolate operations to a novel number. Many animals understand numbers at a basic level for use in essential tasks such as foraging, shoaling, and resource management ...

CRISPR/Cas9 mediated mutations as a new tool for studying taste in honeybees

open access: yesbioRxiv, 2020
Background Honeybees rely on nectar as their main source of carbohydrates [1]. Sucrose, glucose and fructose are the main components of plant nectars [2] [3]. Intriguingly, honeybees express only three putative sugar receptors (AmGr1, AmGr2 and AmGr3) [4]

Knock‐on community impacts of a novel vector: spillover of emerging DWV‐B from Varroa‐infested honeybees to wild bumblebees

open access: yesEcology Letters, 2019
Novel transmission routes can directly impact the evolutionary ecology of infectious diseases, with potentially dramatic effect on host populations and knock‐on effects on the wider host community.

A Pediococcus strain to rescue honeybees by decreasing Nosema ceranae- and pesticide-induced adverse effects.

open access: yesPesticide Biochemistry and Physiology, 2020
Honeybees ensure a key ecosystemic service by pollinating many agricultural crops and wild plants. However, since few decades, managed bee colonies have declined worldwide.

The Waggle Dance as an Intended Flight: A Cognitive Perspective [PDF]

open access: yes, 2019
The notion of the waggle dance simulating a flight towards a goal in a walking pattern has been proposed in the context of evolutionary considerations. Behavioral components, like its arousing effect on the social community, the attention of hive mates ...
