Variations in Nutritional Requirements Across Bee Species

Frontiers in Sustainable Food Systems, Journal Year: 2022, Volume and Issue: 6

Published: Feb. 4, 2022

With 2,000 species currently recorded in Europe, bees are a highly diversified and efficient group of pollinating insects. They obtain their nutrients from nectar pollen flowers. However, the chemical composition these resources, especially (e.g., protein, lipid, amino acids, fatty or sterol content), is variable among plant species. While it well-known that show interspecific variation floral choices, there lack information on nutritional requirements different bee We therefore developed original experiments laboratory conditions to evaluate variations requirements. analyzed content eight blends, terms sterols total concentration profiles. Each blend was provided four model species: honey ( Apis mellifera ), bumblebees Bombus terrestris mason Osmia bicornis cornuta ). For each species, specific protocols were used monitor development weight, timing, survival) resource collection. Overall, we found across those different, low-quality diet for one not necessarily another one. negatively impacted by diets with high protein (~40%), develop normally but struggle low acid content, specifically concentrations 24-methylenecholesterol β-sitosterol. our study supports need conserving and/or introducing diversity into managed ecosystems meet natural preferences at community level.

Abstract Aim Wild bees still face striking shortfalls in knowledge of biodiversity key regions the world. This includes Europe, where despite a long tradition data gathering, continental scale distribution patterns wild have not been systematically analysed to date. study aims characterise large‐scale to: (i) understand spatial–temporal heterogeneity databases, (ii) locate genuine diversity hotspots and their relationship with biogeographical or habitats interests (iii) identify understudied species areas further design conservation actions for most at risk regions. Location Europe. Taxon Bees. Methods We present standardised bee taxonomic phylogenetic using large compilation occurrence records nearly three million validated 1515 species. Results Southern eastern Europe suffer from largest gaps availability while northern western benefit better historical coverage. Our models show that higher is hosted xeric, warm areas, as highlighted by clear latitudinal gradient. However, predicted be more homogenous across than diversity, suggesting policies strategies targeted protect richness may differ those targeting greater diversity.

Ecological, environmental, and management data indicate apple production is driven by wild bee diversity and management practices

Ecological Indicators, Journal Year: 2022, Volume and Issue: 139, P. 108880 - 108880

Published: April 23, 2022

Climate, landscape composition, management practice, and wild bee pollination are all variables thought to play significant roles in commercial apple production. However, how these affect production efficiency under field-realistic conditions has not been investigated at large geographical scales. We combined intensive standardized field surveys (using netting pan traps) with structural equation models explore the relative impact of biotic abiotic on diversity, yield fruit quality, their ability represent reliable proxies Here we show that yields mainly driven by without evidence for a significantly superior contribution managed honey bees. Total while negatively correlated dominance, promoted quality enhancing seed set number. Our study demonstrates even across broad range there is potential harness diversity as nature-based solution substitute an exclusive reliance bees context

Mason bees and honey bees synergistically enhance fruit set in sweet cherry orchards

Ecology and Evolution, Journal Year: 2023, Volume and Issue: 13(7)

Abstract Mason bees ( Osmia spp.) are efficient fruit tree pollinators that can be encouraged to occupy and breed in artificial nesting material. In sweet cherry orchards, they occasionally used as an alternative managed pollinator a replacement for or addition honey Apis mellifera ). Yet, the lack of practical guidelines on management practices, example optimal stocking rates, both mason bee material might compromise pollination service provision. this study, we assessed relationship between rates (honey hives material) abundance 17 Prunus avium ) orchards Central Germany.

Plant–pollinator interactions in apple orchards from a production and conservation perspective

Abstract In an agricultural landscape, production and conservation ideally go hand in hand. a win‐win scenario, measures, such as hedges flower strips, provide support for biodiversity crop example by increased pollination pollinator diversity. However, these measures may also decrease attracting pollinators competing with visits. Here, we studied plant–pollinator interactions from two different perspectives. First, looked at the perspective investigating whether networks differed between apple orchards without adjacent strips hedges. With help of Bayes factor, investigated similarity conclude that there are no differences or Second, analyzed impact on their plants before after bloom April. We showed used more resources across whole season compared to isolated orchards. hedges, were constant over time. beneficial being harmful pollination.

Published: April 25, 2025

Understanding the distribution of pesticides in floral landscape is critical for land managers and regulators, particularly since identifying where exposure occurs to pesticide mitigation. In this study, we developed a bee-plant network commercial sweet cherry (Prunus avium L.) system surrounding unmanaged habitat. We estimated contamination flowering plants by trapping pollen from honey bee colonies, plant species origin pollen, relating non-Apis visitation toxicity detections. Over 90 plant-bee interactions were matched with collected pollen. By combining data, attributed hazard 33 genera. Unlike previous studies, observed greatest bees did not come visits crop or drift off orchard, but an orchard understory (genus Taraxacum). The importance was related both frequency bees. Our findings caution against generalizing how become exposed pesticides.

Abstract Arthropods are essential in maintaining healthy and productive agricultural ecosystems. Agricultural crops such as apples typically pollinated by domesticated honey bees, but wild bees other arthropod flower visitors also contribute to pollination. Flower can be natural enemies of crop‐pests or herbivores. Biodiversity is under pressure knowledge wildflower an important tool designing orchards that support high functional biodiversity. In our study, we assessed the diversity four Danish apple using both molecular nonmolecular techniques study communities Arthropod DNA collected from flowers was analyzed a metabarcoding approach mitochondrial COI marker, while pollinators were recorded through visual assessment surveys. These complementary resulted total 19 taxa detected. Nonbee arthropods constituted large proportion detected methods (84%, 16 taxa). Metabarcoding 12 had 83% species resolution. Visual census recovered visiting groups order level (Coleoptera, Diptera, Hymenoptera Lepidoptera) not provided relative abundance data, which possible with methods. We demonstrated utilizing assess communities, able obtain broader overview fauna present.
