Concentrated vulnerabilities in bees: Diet specialists have smaller geographic ranges
Niche breadth theory predicts a positive association between range size and diet breadth, which could concentrate risk among specialists, but this is not well established for bees. Using global occurrence data (range size) and natural history collection‐derived pollen data (diet breadth), we compared these traits in 633 species from six families and ...

Native bees (Hymenoptera: Apoidea) and berry polycultures: Studying farmers’ motivations for diversification and the impact of mass floral resources on pollinator communities [PDF]
Floral resource continuity is an important component in pollinator conservation. Mass blooms early in the season may bolster pollinator communities on sequentially flowering crops by creating a resource pulse in an agricultural landscape.

Reliability of the entomovector technology using Prestop-Mix and Bombus terrestris L. as a fungal disease biocontrol method in open field [PDF]
Botrytis cinerea Pers.: Fr. is a major plant pathogen, and a new approach is needed for its control in strawberry to minimise the increasing use of synthetic fungicides.

ABSTRACT Flies (Diptera) are important pollinators in global agriculture, yet little is known about how intraspecific trait variation influences their pollination performance. We compared morphological traits, foraging behaviour and pollination‐related performance metrics between laboratory‐reared (hereafter lab‐reared) and wild populations of ...

Bumble bees (Bombus spp.) are key pollinators in Himalayan ecosystem, but habitat degradation and floral resource scarcity threaten their population. Foxglove, Digitalis purpurea, an introduced plant with deep corolla, is an important source of pollen ...

The genomes of two key bumblebee species with primitive eusocial organization [PDF]
Background: The shift from solitary to social behavior is one of the major evolutionary transitions. Primitively eusocial bumblebees are uniquely placed to illuminate the evolution of highly eusocial insect societies.

Rapid disruption of pollination function by the invasive plant Impatiens glandulifera
Invasion by Impatiens glandulifera rapidly disrupts pollination of the native plant Stachys sylvatica by altering pollen transport by shared bumblebee pollinators. A short‐term field introduction revealed a dramatic decline in conspecific pollen deposition within 4 days, showing that pollination function can collapse quickly following invasion, even ...

The large carpenter bee Xylocopa augusti (Hymenoptera: Apidae): new record for Chile [PDF]
The large carpenter bee Xylocopa (Neoxylocopa) augusti Lepeletier de Saint Fargeau, 1841, is here recorded for the first time in Chile. This new record increases to four the number of carpenter bees known for the country.
