Abstract Context To date, managing honey bees and wild within crop fields remains challenging. Landscape structure is often overlooked when studying the pollination contribution of bees. Increasing our understanding on how to predict bee visitation in crops crucial for sustainable management agroecosystems. Objectives With this study we investigated which landscape field-level variables determine visitation, whether or influence pollination. Methods Sixteen highbush blueberry were surveyed bees, Washington, USA. Additionally, a radius 1000 m around each field all hives located surrounding was characterized. Results Honey hive numbers positively correlate with proportion landscape. best predicted by landscape-level density m, whereas semi-natural habitat did not impact visitation. The amount had positive negative impact, respectively, effect seed set. Conclusion We conclude that determined number Hence, recommendations miss contributions from other Furthermore, contributes diversifying pollinator diets provides habitat.

Worldwide, the use of managed bees for crop pollination and honey production has increased dramatically. Concerns about pressures these increases on native ecosystems resulted in a recent expansion literature this subject. To collate update current knowledge, we performed systematic review effects introduced ecosystems, focusing wild bees. enable comparison over time, used same search terms focused impacts as earlier reviews. This covers: (a) interference resource competition between or bees; (b) plants weeds; (c) transmission infectivity pathogens; classifies into positive, negative, neutral. Compared to 2017 review, found that number papers issue by 47%. The highest increase was seen pathogen spill-over, but last five years considerable additional information also become available. Records negative have from 53% reporting 66% at present. majority studies investigated visitation foraging behaviour. While only few experimentally assessed bee reproductive output, 78% demonstrated effects. Plant composition negatively affected 7% studies, 79% pathogens reported potential Taken together, evidence increasingly suggests affect bees, knowledge should inform actions prevent further harm ecosystems.

Taking advantage formerly heterogeneous spatial distribution ectoparasitic mite Varroa destructor that acts as potent virus among honeybees Apis mellifera , we investigated impact its recent global spread on community retrospective study historical samples. We hypothesized has had an effect epidemiology several bee viruses, potentially altering their transmissibility and/or virulence, and consequently prevalence, abundance, or both. To test this, quantified prevalence loads 14 viruses from honeybee samples collected mite-free mite-infested populations four independent regions. The presence dramatically increased load deformed wing virus, cause unsustainably high colony losses. In addition, other became more prevalent were found higher areas, including not known to be actively varroa-transmitted, but which may increase opportunistically varroa-parasitized bees.

The western honey bee (Apis mellifera) is of major economic and ecological importance, with elevated rates colony losses in temperate regions over the last two decades thought to be largely caused by exotic ectoparasitic mite Varroa destructor deformed wing virus (DWV), which transmits. DWV currently exists as main genotypes: formerly widespread DWV-A more recently described rapidly expanding DWV-B. It an excellent system understand viral evolution replacement one variant another. Here we synthesise published results on distribution prevalence -B period 2008-2021 present novel data for Germany, Italy UK suggest that (i) DWV-B has expanded worldwide since its first description 2004 (ii) it potentially replacing DWV-A.

Abstract Insect pollinators face numerous threats, including habitat loss and population fragmentation. The effects of human‐altered landscapes on connectivity need to be better understood inform effective mitigation measures. We examined the literature landscape heterogeneity genetic in two key pollinator groups: bees (Hymenoptera: Anthophila) hoverflies (Diptera: Syrphidae). identified 113 studies from 59 countries, covering 96 bee 21 hoverfly species. However, biased taxonomic geographical coverage limited broad conclusions regarding species susceptibility isolation. Notably, remain significantly understudied, hampering comprehensive assessments patterns. While some demonstrated differentiation across tens kilometres, others maintained entire continents. Various features, water bodies mountain ranges, often acted as barriers gene flow, while impacts deforestation, agriculture, urbanisation were mixed. Biological traits like body size, resource specialisation, sizes found influence contrasting results precluded conclusive findings. Future research should include evaluations time lags statistical power determine appropriateness selected tools for testing hypotheses recent pollinators. Owing increased interest corridors, encompassing a wider range species, habitats, improved study designs, is needed provide an evidence‐based framework conservation
