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 ...

Detection of Nosema spp. in Worker Bees of Different Ages During the Flow Season

Journal of Apicultural Science, 2012
Celem badań było ustalenie, który gatunek Nosema występuje u robotnic Apis mellifera pobieranych z różnych miejsc ula w sezonie pasiecznym. W lutym 2010 roku zbadano osypy zimowe pszczół z 30 rodzin pszczelich.

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

, 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.

Animal medical systems from Apis to apes: history, recent advances and future perspectives

Biological Reviews, Volume 100, Issue 6, Page 2608-2624, December 2025.
ABSTRACTAnimal medical systems encompass a wide range of behaviours aimed at maintaining or improving health. It has become clear that these behaviours are not limited to animals treating themselves (self‐medication) but also include the treatment of group members, resulting in the adoption of the more inclusive term “animal medication”. Behaviour with

North American Propolis Extracts From Upstate New York Decrease Nosema ceranae (Microsporidia) Spore Levels in Honey Bees (Apis mellifera)

Frontiers in Microbiology, 2020
Nosema ceranae infections in honey bees (Apis mellifera) pose a severe threat to colony health. Beekeepers have used dicyclohexylammonium fumagillin to control Nosema apis, although it may be ineffective against N. ceranae. We investigated the ability of

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

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 ...
