Assessment of intestinal parasites in the coexisting Bombus terrestris (Apidae) and Xylocopa augusti (Apidae) in central Chile

open access: yesRevista Chilena de Historia Natural, 2020
Bombus terrestris is a European bumblebee extensively commercialized worldwide for crop pollination. In Chile, this species was introduced in 1997 and after confinement escape, it has spread and established in several localities of central-southern Chile

Dataset of the next-generation sequencing of variable 16S rRNA from bacteria and ITS2 regions from fungi and plants derived from honeybees kept under anthropogenic landscapes

open access: yesData in Brief, 2021
Forager Apis melliefera honeybees were collected from four localities located in Europe, i.e.: London, UK; Athens, Greece; Marchamalo, Spain and Lublin, Poland. Furthermore, from Asia we have collected A. mellifera as well as A.

Pollen extracts and constituent sugars increase growth of a trypanosomatid parasite of bumble bees [PDF]

open access: yesPeerJ, 2017
Phytochemicals produced by plants, including at flowers, function in protection against plant diseases, and have a long history of use against trypanosomatid infection.

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

open access: yesPeerJ, 2014
Honey bees and, more recently, bumblebees have been domesticated and are now managed commercially primarily for crop pollination, mixing with wild pollinators during foraging on shared flower resources.

No effect of dual exposure to sulfoxaflor and a trypanosome parasite on bumblebee olfactory learning

open access: yesScientific Reports, 2022
Bees are important pollinators in wild and agricultural ecosystems, and understanding the factors driving their global declines is key to maintaining these pollination services.

Parasites of the genus Nosema, Crithidia and Lotmaria in the honeybee and bumblebee populations: a case study in India

open access: yesВавиловский журнал генетики и селекции, 2018
The populations of honeybees and bumblebees have been decreasing around the world in the recent decades. A variety of pathogens and parasites, including  bacteria, fungi, protozoa, nematodes, mites and insects play signi ficant role in honeybee and ...

Infection and transmission of Nosema bombi in Bombus terrestris colonies and its effect on hibernation, mating and colony founding [PDF]

open access: yes, 2008
The impact of the microsporidium Nosema bombi on Bombus terrestris was studied by recording mating, hibernation success, protein titre in haemolymph, weight change during hibernation, and colony founding of queens that were inoculated with N.

Recognition and avoidance of contaminated flowers by foraging bumblebees (Bombus terrestris). [PDF]

open access: yesPLoS ONE, 2011
Bumblebee colonies are founded by a single-mated queen. Due to this life history trait, bumblebees are more susceptible to parasites and diseases than polyandrous and/or polygynous social insects.

Larvae act as a transient transmission hub for the prevalent bumblebee parasite Crithidia bombi. [PDF]

open access: yesJ Invertebr Pathol, 2017
Disease transmission networks are key for understanding parasite epidemiology. Within the social insects, structured contact networks have been suggested to limit the spread of diseases to vulnerable members of their society, such as the queen or brood ...

Molecular and phylogenetic characterization of honey bee viruses, Nosema microsporidia, protozoan parasites, and parasitic mites in China [PDF]

open access: yes, 2013
China has the largest number of managed honey bee colonies, which produce the highest quantity of honey and royal jelly in the world; however, the presence of honey bee pathogens and parasites has never been rigorously identified in Chinese apiaries.
