Identification of Nosema ceranae in the Valparaíso District, Chile [PDF]

Archivos de medicina veterinaria, 2014
El presente estudio demostró por primera vez la presencia de Nosema ceranae en la V Región de Valparaíso. Las muestras analizadas fueron obtenidas en la Región de Valparaíso, pertenecientes a colmenas ubicadas en las localidades de San Antonio, Limache y La Ligua. Las muestras obtenidas de grupos de 60 abejas fueron maceradas y analizadas por

First Detection of Nosema ceranae Infecting Apis mellifera in India

Journal of Apicultural Science, 2019
Apis mellifera colonies were sampled for over twelve months to study the Nosema infection in different apiaries of Himachal Pradesh, India. We found that the infection incidence was highest in the winter season (48.40 %) followed by autumn and rainy ...

Long-Term Temporal Trends of Nosema spp. Infection Prevalence in Northeast Germany: Continuous Spread of Nosema ceranae, an Emerging Pathogen of Honey Bees (Apis mellifera), but No General Replacement of Nosema apis

Frontiers in Cellular and Infection Microbiology, 2017
The Western honey bee (Apis mellifera) is widely used as commercial pollinator in worldwide agriculture and, therefore, plays an important role in global food security.

Urban landscapes tend to increase the presence of pathogenic protozoa, microsporidia and viruses, but likely decrease the abundance of viruses in wild bees and wasps

Insect Science, Volume 32, Issue 6, Page 1911-1925, December 2025.
• The bees Anthophora plumipes and Osmia cornuta had a higher occurrence probability of the neogregarine protozoan Apicystis bombi in more fragmented urban areas.• In the bee Halictus scabiosae and wasp Polistes dominula, hotter urban areas increased the likelihood of occurrence of viruses.• The viruses were found to be replicative in the samples, and ...

Molecular Surveillance of Honey Bee Hives Using eDNA Metabarcoding During Pollination Season

Environmental DNA, Volume 7, Issue 6, November–December 2025.
Healthy honey bees are critical in safeguarding our food supply, but monitoring their health may present a significant challenge. Here, we used environmental DNA (eDNA) metabarcoding on bee hive debris and detected species of arthropods, bacteria and fungi contributing to form the bee hive environment, including hive pests and pathogens as well as hive

Nosema distribution across Portugal. Results from the first nationwide survey (2011-12) [PDF]

, 2013
A nationwide field sampling exercise was launched in 2011, to address mounting anecdotal evidence of atypically high honey bee colony mortalities of unexplained origin occurring throughout Portugal. The first approach was to contact 662 beekeepers (≈ 4%

How Population Structure and Nest Membership Shape Pathogen Patterns in Bumble Bees

Molecular Ecology, Volume 34, Issue 22, November 2025.
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 ...

The State of Beekeeping in India: Insights, Gaps, and Emerging Opportunities

Entomological Research, Volume 55, Issue 10, October 2025.
ABSTRACT India's beekeeping industry primarily revolves around two domesticated honey bee species, Apis cerana and A. mellifera, which are central to commercial beekeeping. In addition, there are four wild honey bee species—A. dorsata, A. laboriosa (sympatric with A. dorsata), A. florea, and A. andreniformis (sympatric with A.

Innovative Airborne DNA Approach for Monitoring Honey Bee Foraging and Health

Environmental DNA, Volume 7, Issue 4, July–August 2025.
Using a novel modification of our simple hand airborne eDNA samplers this pilot study demonstrates that eDNA filtered from the air of a honey been colony has the strong potential for rapid screening of honey bee health and for the study of bee foraging behavior. ABSTRACT Environmental DNA (eDNA) refers to genetic material collected from the environment

Identification of candidate agents active against N. ceranae infection in honey bees: establishment of a medium throughput screening assay based on N. ceranae infected cultured cells. [PDF]

PLoS ONE, 2015
Many flowering plants in both natural ecosytems and agriculture are dependent on insect pollination for fruit set and seed production. Managed honey bees (Apis mellifera) and wild bees are key pollinators providing this indispensable eco- and agrosystem ...
