Incidence and treatment of European foulbrood and sacbrood disease of honey bees (Apis mellifera linn.) in kangra valley: A review

Journal of Entomology and Zoology Studies
Honey bees and honey comb bees are very valuable for wild flowering plants and economically important crop due to their role as pollinators. However, these insects confront many diseases threats (viruses, parasites, bacteria and fungi and large pesticide

Honey Bee Colony Health in Thiamethoxam‐Treated Sugar Beet Fields: A Field‐Based Case Study

Ecology and Evolution, Volume 15, Issue 12, December 2025.
Using multi‐site field trials during Germany's 2021 emergency authorization of thiamethoxam‐treated sugar beet, we combined colony demography and residue analyses with complementary worker survival assays to characterize honey bee exposure under realistic conditions.

Development and validation of a novel field test kit for European foulbrood [PDF]

Apidologie, 2008
European foulbrood (EFB) is a serious and widespread disease of honey bee larvae. It is a notifiable disease in the United Kingdom under existing legislation, so colonies must be officially screened for signs of disease. The current study developed a rapid and sensitive test to diagnose EFB in the field.

Effects of essential oils on foulbrood bacteria and honey bee workers (Apis mellifera) under laboratory conditions

Frontiers in Insect Science
IntroductionAmerican and European foulbrood diseases (AFB and EFB, respectively) result in considerable economic losses for beekeepers. Currently, no satisfactory methods are available for the treatment of either disease. There has been a recent surge of

Honey Bee Pathogen Prevalence and Interactions within the Marmara Region of Turkey

Veterinary Sciences, 2022
Beekeeping has yet to reach its full potential in terms of productivity in Turkey where it has a relatively large role in the economy. Poor colony health is suspected to be the reason for this, but comprehensive disease monitoring programs are lacking to

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

Synthesis, Characterization and in Vitro Antibacterial Activities of CdO Nanoparticle and Nano-sheet Mixed-ligand of Cadmium(ІІ) Complex [PDF]

Nanochemistry Research, 2016
Here, we report the synthesis of a Schiff-base mixed-ligand complex of cadmium(ІІ) in bulk and nano-scales via the precipitation and sonochemical methods, respectively. The complex formula is [Cd(3-bpdh)(3-bpdb)Cl2]n (1), where the ligands are 3-bpdh = 2,

Landscape‐Wide Metabarcoding Shows Interactions Among the Gut Microbiome and Pollen Diversity in the Invasive Bumblebee, Bombus terrestris

Ecology and Evolution, Volume 15, Issue 7, July 2025.
The study examines how environmental factors and dietary diversity influence the gut microbiome of the invasive European buff‐tailed bumblebee (Bombus terrestris) in Tasmania. We found that gut bacterial composition and diversity were significantly affected by annual precipitation, pasture percentage, temperature and interactions between pollen ...

European foulbrood of honeybee – in short

, 2023
European foulbrood of honeybee (EFB) is a bacterial disease that infects young brood up to 48 hours of age. The primary causative agent is Melissococcus plutonius, a Gram-positive lanceolate or round bacterium that requires cultivation under artificial conditions.

Peritrophic matrix-degrading proteins are dispensable virulence factors in a virulent Melissococcus plutonius strain

Scientific Reports, 2021
European foulbrood (EFB) caused by Melissococcus plutonius is a major bacterial disease of honey bees. Strains of the causative agent exhibit genetic heterogeneity, and the degree of virulence varies among strains.
