Zymography of proteases in honey bees (Apis Mellifera) infected with Nosema ceranae [PDF]

Veterinarski Glasnik
Nosemosis is one of the most important honey bee diseases and is caused by two fungal species of the genus Nosema, i.e., Nosema apis and Nosema ceranae.

Unraveling Long‐Term Microsporidia Diversity and Dynamics in Lake Aydat (France) Through Paleogenomics

Environmental DNA, Volume 8, Issue 3, May–June 2026.
Sedimentary ancient DNA study revealed 138 years of hidden microsporidian (unicellular eukaryotic parasite) diversity and host–parasite dynamics in a freshwater lake. A major community shift in the 2000s, linked to anthropogenic pressures, shows how paleogenomics reveals the diversity and long‐term ecological trajectories of these previously overlooked

Genome Structure, Evolution, and Host Shift of Nosema

Biology
Nosema is a diverse fungal genus of unicellular, obligate symbionts infecting various arthropods. We performed comparative genomic analyses of seven Nosema species that infect bees, wasps, moths, butterflies, and amphipods.

Presence of Nosema ceranae associated with honeybee queen introductions

, 2014
Microsporidiosis caused by Nosema species is one of the factors threatening the health of the honeybee (Apis mellifera), which is an essential element in agriculture mainly due to its pollination function.

Las asociaciones entre Nosema spp. hongos, ácaros Varroa destructor, y tratamientos químicos en abejas de la miel, Apis mellifera [PDF]

, 2016
Nosema spp. and Varroa destructor are common parasites of honey bee colonies. Beekeepers routinely treat colonies with the fungicide fumagillin to control Nosema and an array of miticides to control V. destructor. Interactions between these parasites and

Environment and Pollen Diversity Differentially Affect the Gut Microbiomes of Introduced Honeybees and Bumblebees

Evolutionary Applications, Volume 19, Issue 4, April 2026.
ABSTRACT Invasive species may exhibit shifts in their gut microbiome in response to novel environments and diet, but this may differ across host species and their time since colonisation. We investigate if site environmental variables and foraged pollen resources differentially shape the gut microbiomes of two bee species with contrasting introduction ...

Drivers of Viral Prevalence in Landscape‐Scale Pollinator Networks Across Europe: Honey Bee Viral Density, Niche Overlap With This Reservoir Host and Network Architecture

Ecology Letters, Volume 29, Issue 1, January 2026.
Viral spill‐over from honey bees is a potential threat to wild pollinators. We used causal modelling approaches to detect the main drivers of spill‐over. Honey bee viral density, niche overlap with honey bees, urbanisation and plant‐pollinator network structure all played an important role in the transmission of BQCV, DWV‐A and DWV‐B.

Midgut proteases from larval spodoptera littoralis (lepidoptera: noctutoae) [PDF]

, 1992
The presence and properties of proteases present in larval midgut extracts from Spodoptera littoralis was investigated. Trypsin and chymotrypsin activities were found mainly in the midgut lumen while leucine aminopeptidase and dipeptidyl aminopeptidase ...

Translocation of imidacloprid from coated rape (Brassica napa) seeds to nectar and pollen [PDF]

, 2013
Bees and other pollinating insects contribute significantly to the world’s production of edible crops. Bees and bumblebees are threatened by modern agricultural practices like monocropping, destruction of natural habitats and pesticide use.
