Proteomic analysis of summer and winter Apis mellifera workers shows reduced protein abundance in winter samples

Apis mellifera workers display two stages; short lived summer bees that engage in nursing, hive maintenance and foraging, and long lived winter bees (diutinus bees) which remain within the hive and are essential for thermoregulation and rearing the next generation of bees in spring before dying. Label free quantitative proteomic analysis was conducted on A.…

4-Year Overview of Winter Colony Losses in Greece: Citizen Science Evidence That Transitioning to Organic Beekeeping Practices Reduces Colony Losses

The honey bee is one of the most important pollinators with a close relationship to humans. The questionnaire from the non-governmental association “COLOSS”, answered by beekeepers around the world, is a valuable tool for monitoring and analyzing factors involved in overwintering losses, as well as for understanding the evolution of the beekeeping sector over the…

Exploring the impact of RF-EMF exposure on planetary health

Approaches to assess the impact of emerging technology from a planetary perspective, while exploring options for exposure reduction and interacting with citizens and stakeholders about exposure levels and possible associated risks. Following a citizen science paradigm, ETAIN will develop an app and a platform able to quantify one’s personal exposure to RF-EMF (Radiofrequency Electromagnetic Fields).…

Chronic Exposure to Polystyrene Microplastic Fragments Has No Effect on Honey Bee Survival, but Reduces Feeding Rate and Body Weight

Microplastics (MPs), in the form of fragments and fibers, were recently found in honey samples collected in Ecuador as well as in honey bees collected from Denmark and China. However, little is known about how MPs impact bee health. To fill this knowledge gap, we investigated the potential toxicity of irregularly shaped polystyrene (PS)-MP fragments…

Revealing some Elements and Heavy Metals in Honeybee and Beeswax Samples Collected from Different Environments

Honeybees and their products are good bioindicators because they are inextricably linked to the natural environment they inhabit. The objectives of this research were to detect and identify pollution extent by the levels of metals in honeybees (foragers) (Apis mellifera jemenatica) and beeswax, including some elements such as K, Ca, Na, Mg, Fe, Mn, Cu,…

Chronic in‑hive exposure to a field‑relevant concentration of Closer™ SC (24% sulfoxaflor) insecticide altered immunological and physiological markers of honey bee foragers (Apis mellifera)

Sulfoxaflor (SULF), a well-known alternative for the banned neonicotinoids, is not environmentally persistent, yet numerous studies using field-realistic levels have demonstrated its detrimental impact on honey bee colonies. Despite this, even just a limited number of studies have addressed its residue-level effects on the physiological and immunological biomarkers of foraging honey bees in semi-field conditions.…

Sublethal effects of herbicides clethodim, haloxyfop-P-methyl, and their mixture on honey bee health

Herbicides are the most frequently used pesticides, accounting for more than 60% of all pesticides used in agriculture around the world. Clethodim (CTD) (Vixtol Super® 24% EC), haloxyfop-p-methyl (HFM) (Gallant Super® 10.8% EC), and their mixture (CTD (15%) + HFM (7.5%) (Fine® 22.5% EC) are among the most commonly used post-emergence graminicides in Egypt and worldwide. However,…
