There is evidence that specialised metabolites of flowering plants occur in both vegetative parts and floral resources (i.e., pollen nectar), exposing pollinators to their biological activities. While such may be toxic bees, it also help them deal with environmental stressors. One example heather nectar which has been shown limit bumble bee infection by a trypanosomatid parasite, Crithidia sp., because callunene activity. Besides nectar, harbours high content as flavonoids but they have poorly investigated. In this study, we aimed assess the impact its on bees using non-parasitised parasitised microcolonies fed either control diet willow pollen), diet, or flavonoid-supplemented diet. We found significantly affected decreasing collection well offspring production, increasing male fat body while parasite exposure had no significant effect except for an increase body. did not find any medicinal bees. Our results provide insights into heather-bumble bee-parasite interactions. They underline contrasting roles two emphasize importance considering when addressing effects plant pollinators.

Whether soil heavy metal pollution contributes to the decline in pollinator populations remains inconclusive. Based on detection of metals nectar, pollen, and bodies pollinating insects areas affected by pollution, this study aimed investigate impact adding four metals-zinc (Zn), lead (Pb), copper (Cu), nickel (Ni)-at realistic concentrations diet pre-oviposition period, larval development production adult bees, weight worker bees. The sought evaluate influence accumulation mediated floral rewards key stages growth bumblebee (Bombus terrestris L.). Results revealed that Zn, Pb, Cu significantly extended period queen with Pb doubling time at high Ni showing no significant effect moderate low concentrations. Lead, Cu, medium concentrations, whereas Zn only had a reduced bee yield body bees different among which 25%-40%. concentration was most obvious, reduction 30%. Our findings support hypothesis rewards, can have serious some bumblebees.

Chalkbrood is a disease of honey bee brood caused by the fungal parasite Ascosphaera apis. Many factors such as genetics, temperature, humidity and nutrition influence appearance clinical symptoms. Poor impairs immune system, which favors manifestation symptoms many diseases. However, direct link between dietary ingredients chalkbrood has not yet been established. We show here that elemental composition mummies healthy larvae from same infected hives differ, well differ hives. had highest concentration macroelements Na, Mg, P, S, K Ca some microelements Rb Sn, at time lowest B, As, Sr, Ag, Cd, Sb, Ba Pb. Larvae contained less Pb, Ba, Cs, Zn, Cu, Ni, Co, Mn, Cr, V Al in contrast to disease-free apiary. This first study demonstrate differences, suggesting an infection alters larval or predisposition for outbreak infection. Though, based on results obtained case study, rather than controlled experiment, our findings stress differences elements versus diseased larvae.

We present a review about histological sub-lethal effects due to anthropogenic contaminants on the midgut of bees and other aculeate hymenopterans. Contaminant types, damage methodology were extracted summarized from 74 published articles, then quantitatively analyzed. found that western honeybee (Apis mellifera) is by far most widely used model. Contaminants have largely been tested under laboratory conditions, particularly insecticides fungicides. Tissue-level (e.g., degradation epithelium peritrophic membrane) often detected together with cell-level cell vacuolisation, karyorrhexis). Descriptive statistics mixed models suggested herbicides may cause specific mix alterations an overall lower severity compared pesticides, while combined use light electron microscopy seemed detect more types. claim for efforts reduce biases in future studies such effects, allowing their clearer as markers human activities.

Pollution in mining areas represents a major environmental issue, significantly impacting ecosystems and human health. This study highlights propolis as an efficient natural bioindicator for detecting assessing the degree of contamination these areas. The objective this is to determine levels metals (Pb, Cd, As, Cr, Fe, Mn, Cu, Zn) from exploitation Romania, specifically counties Alba, Hunedoara, Maramureș, Caraș-Severin. Although operations are closed, anthropogenic impact varies due differences surface zones affected, occupied by waste heaps, local hydrological conditions, partial ecological rehabilitation efforts. To highlight contamination, reference area considered unaffected activities was used benchmark each county. values obtained investigated were compared with those control zone specific pollution.

Abstract Honey bees are social insects that show division of labor and sexual dimorphism. Female honey differentiate in two different castes, queens or worker bees, while males called drones. Worker have tasks the hive including collection food, its processing, caring for brood, protecting hive, producing wax. The drones’ only role is to mate with a virgin queen. Many studies dealt differences physiology, behavior, morphology workers This first study demonstrates element accumulation composition between drones bees. Using inductively coupled plasma mass spectrometry, we found higher concentrations most elements analyzed. Drones had essential Na, P, S, Zn, Cu, especially Se (2.2 × higher), which known be important sperm quality fertility many animals. Until now content was not observed male insects.

The use of sewage sludge as a soil improver has been promoted in agroecosystems. However, sludges can contain toxic trace elements because suboptimal wastewater treatment. Nonetheless, field studies investigating the negative effects these practices on pollinators are lacking. We collected honeybees from an area where is widespread, and one it precluded. Trace soils bees were quantified. Cadmium, chromium, lead, mercury, nickel investigated they least correlated to each other known be toxic. Their levels related oxidative stress energy biomarkers, midgut epithelial health, body size wing asymmetry honeybees. found increased carbohydrate content sites with higher cadmium levels, histological damage epithelium area, presence dark spherites highest lead levels.

Humans and bees share millennia of history that have resulted in ever-increasing connection interdependence. Thus, today, it is impossible to ignore the influence humans on bees, particularly regarding decrease their numbers due environmental contamination. Although they do not cause immediate mortality, heavy toxic metals, along with dangers such as bee diseases, pesticides, habitat destruction, climate change, threaten number should be ignored. Honeybees, colonies, products are recognized accumulators metals biological indicators presence these all components. This study an overview prominent research from past three decades metal levels honeybees (Apis mellifera L.), honey, wax, pollen. compares Al, As, Cd, Co, Cr, Cu, Fe, Hg, Mn, Ni, Pb, Se, Zn natural environments environment where anthropogenic pressure manifests.
