A clash on the Toll pathway: competitive action between pesticides and zymosan A on components of innate immunity in Apis mellifera

open access: yesFrontiers in Immunology, 2023
BackgroundThe immune system of honeybees includes multiple pathways that may be affected by pesticide exposure decreasing the immune competencies of bees and increasing their susceptibility to diseases like the fungal Nosema spp.

A GABA Receptor Modulator and Semiochemical Compounds Evidenced Using Volatolomics as Candidate Markers of Chronic Exposure to Fipronil in Apis mellifera

open access: yesMetabolites, 2023
Among the various “omics” approaches that can be used in toxicology, volatolomics is in full development. A volatolomic study was carried out on soil bacteria to validate the proof of concept, and this approach was implemented in a new model organism ...

Economics of alternative insecticide treatments and pollinators in Winter canola

open access: yesCogent Food & Agriculture, 2023
In the US central and southern Great Plains, canola (Brassica napus) is a winter annual crop. It is pollinated by insects, particularly native bees and introduced honeybees (Apis mellifera Linnaeus, 1758). Canola is beset by many insect pests.

Combined Effects of Pesticides and Electromagnetic-Fields on Honeybees: Multi-Stress Exposure

open access: yesInsects, 2021
Honeybee and general pollinator decline is extensively reported in many countries, adding new concern to the general biodiversity loss. Many studies were addressed to assess the causes of pollinator decline, concluding that in most cases multi-stress ...

Honeybee navigation [PDF]

open access: yesCurrent Biology, 2003
Why the interest in honeybees? Many of us have marvelled at the ability of honeybees to find an attractive flower patch, miles away from their hive, and to return to it repeatedly with unerring accuracy. How do they do this with a brain smaller than a sesame seed? We don't know all the answers yet, but bees seem to be able to estimate the distance to a

Evolutionary dynamics on a regular networked structured and unstructured multi‐population

open access: yesInternational Journal of Robust and Nonlinear Control, EarlyView., 2023
Abstract In this paper, we study collective decision‐making in a multi‐population framework, where groups of individuals represent whole populations that interact by means of a regular network. Each group consists of a number of players and every player can choose between two options.
