Effects of exposure of honey bee colonies to neonicotinoid seed–treated maize crops

open access: yesJournal of Apicultural Science, 2013
The effects to honeybee colonies (Apis mellifera L.) during and after exposure to flowering maize (Zea mays L.), grown from seeds coated with clothianidin and imidacloprid was assessed in field-realistic conditions.

Reproduction Number And Asymptotic Stability For The Dynamics of a Honey Bee Colony with Continuous Age Structure [PDF]

open access: yesarXiv, 2016
A system of partial differential equations is derived as a model for the dynamics of a honey bee colony with a continuous age distribution, and the system is then extended to include the effects of a simplified infectious disease. In the disease-free case we analytically derive the equilibrium age distribution within the colony and propose a novel ...

Tracking all members of a honey bee colony over their lifetime [PDF]

open access: yesarXiv, 2018
Computational approaches to the analysis of collective behavior in social insects increasingly rely on motion paths as an intermediate data layer from which one can infer individual behaviors or social interactions. Honey bees are a popular model for learning and memory.

Novel eDNA approaches to monitor Western honey bee (Apis mellifera L.) microbial and arthropod communities

open access: yesEnvironmental DNA
Pests and pathogens are a continuous threat to the health of Western honey bee Apis mellifera L. Monitoring honey bee colonies for arthropod pests, disease‐causing bacteria and fungi, and early detection of new invasions is essential to maintain the ...

First molecular detection of Chronic Bee Paralysis Virus (CBPV) in Iran

open access: yesArchives of Razi Institute, 2015
Among the viruses infecting honey bees, chronic bee paralysis virus (CBPV) is known to induce significant losses in honey bee colonies. CBPV is an unclassified polymorphic single stranded RNA virus. Using RT-PCR, the virus infections in honey bees can be

Adaptive Bee Colony in an Artificial Bee Colony for Solving Engineering Design Problems [PDF]

open access: yesarXiv, 2012
A wide range of engineering design problems have been solved by the algorithms that simulates collective intelligence in swarms of birds or insects. The Artificial Bee Colony or ABC is one of the recent additions to the class of swarm intelligence based algorithms that mimics the foraging behavior of honey bees.

The complex world of honey bee vibrational signaling: A response to Ramsey et al. (2017) [PDF]

open access: yesarXiv
Ramsey et al. report on the characteristics and temporal distribution of an interesting vibrational signal that they term the whooping signal, primarily based upon a long-term study of vibrations recorded by accelerometers placed inside two honey bee (Apis mellifera) colonies, one in France and one in the United Kingdom. The goal of the study, the long-
