A scientific note on Nosema bombi infection intensity among different castes within a Bombus auricomus nest [PDF]

Apidologie, 2016
Bumble bees (Bombus) provide vital services to agricultural and natural plant systems (Kremen et al. 2002; Fontaine et al. 2006). A survey across diverse North American Bombus species detected higher prevalence of infection by the microsporidian parasite Nosema bombi in declining relative to non-declining species, indicating a correlation between ...

The Pathogens Spillover and Incidence Correlation in Bumblebees and Honeybees in Slovenia

Pathogens, 2021
Slovenia has a long tradition of beekeeping and a high density of honeybee colonies, but less is known about bumblebees and their pathogens. Therefore, a study was conducted to define the incidence and prevalence of pathogens in bumblebees and to ...

Nosema bombi(Microsporidia: Nosematidae) and Trypanosomatid Prevalence in Spring Bumble Bee Queens (Hymenoptera: Apidae:Bombus) in Kansas [PDF]

Journal of the Kansas Entomological Society, 2014
Abstract Several species of bumble bees are declining in the United States; these declining populations often show higher prevalence of Nosema bombi, a microsporidian pathogen. To date, surveys of bumble bee pathogens in the United States have only been conducted on workers and males, yet the health of a population is ultimately dependent on the ...

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

Вавиловский 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 ...

Short communication: First data on the prevalence and distribution of pathogens in bumblebees (Bombus terrestris and Bombus pascuorum) from Spain

Spanish Journal of Agricultural Research, 2017
Bumblebees provide pollination services not only to wildflowers but also to economically important crops. In the context of the global decline of pollinators, there is an increasing interest in determining the pathogen diversity of bumblebee species.

Bumble bee parasite prevalence but not genetic diversity impacted by the invasive plant Impatiens glandulifera [PDF]

Ecosphere, 2019
While many bee species are experiencing population declines, some host plant generalist bees remain common in Europe, partly because they seem able to shift to new resources.

PLoS ONE, 2019
Bumblebees (tribe Bombini, genus Bombus Latreille) play a pivotal role as pollinators in mountain regions for both native plants and for agricultural systems.

How Population Structure and Nest Membership Shape Pathogen Patterns in Bumble Bees. [PDF]

Mol Ecol
ABSTRACT Host density, genetic diversity and social groups are key factors influencing pathogen transmission in wildlife populations, but their interactions remain poorly understood in insects. Islands can provide natural laboratories with distinct populations that vary in density and genetic diversity, whereby dense, genetically homogeneous ...

Pesticide and Pathogen Exposure Causes Idiosyncratic Gene Expression Responses Across Four Diverse North American Bumble Bee Species. [PDF]

Mol Ecol
ABSTRACT Bumble bee (Bombus Latreille) populations of certain species have declined precipitously in North America over several decades. Hypotheses for declines include exposure to the pathogen Nosema bombi and neonicotinoid pesticides. Importantly, populations of some bumble bee species remain stable despite their presumed exposure to these same ...
