Exposure of Larvae of the Solitary Bee Osmia bicornis to the Honey Bee Pathogen Nosema ceranae Affects Life History [PDF]
Wild bees are important pollinators of wild plants and agricultural crops and they are threatened by several environmental stressors including emerging pathogens. Honey bees have been suggested as a potential source of pathogen spillover.

Landscape influence on pollinator population genetic connectivity
We analysed 113 studies from 59 countries, covering 96 bee and 21 hoverfly species, to review the evidence of environmental and landscape effects on the population genetic connectivity in pollinators. Environmental conditions (precipitation and temperature), topography (elevation and sea), and land use (agriculture, deforestation, urbanisation) were ...

Unusual nesting behavior in Megachile (Eutricharaea) rotundata (Hymenoptera: Megachilidae) [PDF]
The Alfalfa Leafcutter Bee, Megachile (Eutricharaea) rotundata (Fabricius), is one of the most studied solitary bees in the world. Although its nesting biology is well documented, it has not yet been reported nesting in cavities that expose the nests to

Host‐Cleptoparasite Biogeographical Congruence Through Time: The Case of Cuckoo Oil Bees
ABSTRACT Aim Insect brood parasites (i.e., cleptoparasites), like cuckoo bees, typically attack hosts within specific lineages, but seem to be less constrained by the biogeographical movements of their hosts compared to obligate parasites. Cuckoo bees depend on stable host populations, being particularly sensitive to environmental changes and thus ...

ABSTRACT Managed crop pollination strongly relies on the honeybee Apis mellifera and the bumblebee Bombus terrestris, which is risky, may impact wild pollinator communities and does not always give the best pollination outcomes. The mason bees Osmia cornuta and Osmia bicornis are increasingly used as alternative crop pollinators, but it is not clear ...
