Summary 1. Over a million commercially produced bumblebee colonies are imported annually on a global scale for the pollination of greenhouse crops. After importation, they interact with other pollinators, with an associated risk of any parasites they carry infecting and harming native bees. National and supranational regulations are designed to prevent this, and commercially produced bumblebee colonies are accordingly now often sold and imported as being parasite-free. 2. Here, we used…

Hygienic food to reduce pathogen risk to bumblebees.

The potential for parasite spill-back from commercial bumblebee colonies: a neglected threat to wild bees?

The results show that commercial bumblebee populations do pick up infections, most likely from wild bees, and that these infections can reach prevalences where they may pose a threat to wild bees via parasite spill-back.

Prevalence of Nosema microsporidians in commercial bumblebees (Bombus terrestris) is not related to the intensity of their use at the landscape scale

The initial infection status of commercial Bombus terrestris colonies is assessed in SW Spain and spatial and seasonal influences on changes in parasite prevalence across a landscape where bumblebee colonies are intensively used to pollinate berry crops are explored.

Bumble Bee Breeding on Artificial Pollen Substitutes

Abstract Bumble bees are important pollinators for many temperate crops. Because of the growing demand for food from entomophilous crops, bumble bee colonies are commercially reared and placed in

Occurrence of Honey Bee (Apis mellifera L.) Pathogens in Wild Pollinators in Northern Italy

These results encourage the implementation of monitoring actions aiming to improve the understanding of the environmental implications of such interspecific transmission events among honey bees and wild pollinators, which is pivotal to embracing a One Health approach to pollinators’ welfare.

The relationship between managed bees and the prevalence of parasites in bumblebees

These results support previous reports of parasite spillover from commercially produced bumblebee to wild bumblebees, and suggest that the impact of stress from competing with managed bees or the vectoring of parasites by them on parasite prevalence in wild bees needs further investigation.

Introduction of Non-Native Pollinators Can Lead to Trans-Continental Movement of Bee-Associated Fungi

It is demonstrated that fungi from the genus Ascosphaera have been transported to North America along with the bee from its native range in Japan, and that O. cornifrons is exposed to fungi previously only identified from nests of other related bee species.

Pervasiveness of Parasites in Pollinators

A preliminary screening of pollinators in the UK for parasites is carried out, finding that about a third of bumblebees and wasps, as well as all honey bees, were positive for deformed wing virus, but that this virus was not present in other pollinators.

Effects of Invasive Parasites on Bumble Bee Declines

It is suggested that the development of molecular screening protocols, thorough sanitation efforts, and cooperation among nongovernmental organizations, governments, and commercial breeders might immediately mitigate these threats to native bumble bee populations.

Bumblebee commercialization will cause worldwide migration of parasitic mites

The results indicate that transportation of bumblebee colonies will cause overseas migration of parasitic mites of different origins.

Does Pathogen Spillover from Commercially Reared Bumble Bees Threaten Wild Pollinators?

A spatially explicit model of pathogen spillover in bumble bees is constructed and, using laboratory experiments and the literature, parameter values for the spillover of Crithidia bombi, a destructive pathogen commonly found in commercial Bombus are estimated.

Worldwide migration of parasitic mites as a result of bumblebee commercialization

The results suggest that bumblebee commercialization has caused overseas migration and cross-infestation of parasitic mites among natural and commercial colonies.

Consumption of a nectar alkaloid reduces pathogen load in bumble bees

Lighter pathogen loads may relieve bees from the behavioral impairments associated with the infection, thereby improving their foraging efficiency and if the collection of nectar secondary metabolites by pollinators is done as a means of self-medication, pollinators may selectively maintain secondary metabolites in the nectar of plants in natural populations.

Alien parasite hitchhikes to Patagonia on invasive bumblebee

The results suggest that Patagonia had been free of A. bombi until this parasite was co-introduced with B. terrestris, and spilled over in situ to these two previously resident species, including the native Bombusdahlbomii.
