The Prevalence of Nosemosis in Honey Bee in The Province of Kars

, 2004
 Kars yöresindeki bal arılarında (Apis mellifera) nosemosis’ in prevalansını saptamak amacıyla 8 ana yerleşim yerinden tesadüfen seçilen 50 arılıktan arı numuneleri alınmıştır. Arılıklar Mayıs 2001- Eylül 2002 tarihleri arasında bir kez ziyaret edilmiş ve toplam 1892 koloniden rastgele seçilen 343 (% 18.13) arı kovanından arı örnekleri alınmıştır.

Extracts From Grapefruit (Citrus paradisi) Peel via Microwave-Assisted and Conventional Extractions: Evaluation of Nosema Infection and Toxicity in Honey Bees. [PDF]

Vet Med Sci
Conventional and microwave‐assisted extractions of grapefruit peels were optimized using response surface methodology (RSM) based on TPC, TFC, and antioxidant activity (DPPH). The phytochemical profiles of the two optimum extracts were characterized via HPLC before evaluating their acute and chronic toxicity, as well as their effects on honey bee (Apis

Safety and efficacy of a feed additive consisting of Pediococcus acidilactici CNCM I‐4622 for all insect species (Danstar Ferment AG)

EFSA Journal, Volume 21, Issue 12, December 2023., 2023
Abstract Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the safety and efficacy of Pediococcus acidilactici CNCM I‐4622 as a zootechnical additive (functional group: physiological condition stabilisers) for all insects. The active agent used in the additive is already authorised for use in all animal

Honeybee visitation to shared flowers increases Vairimorpha ceranae prevalence in bumblebees

Ecology and Evolution, Volume 13, Issue 9, September 2023., 2023
We conducted an observational study among different pollinator communities in agricultural fields to understand (1) how floral visitation patterns differ among pollinator species and (2) whether the visitation patterns are linked with V. ceranae prevalence in honeybees and bumblebees.

Integrative population genetics and metagenomics reveals urbanization increases pathogen loads and decreases connectivity in a wild bee

Global Change Biology, Volume 29, Issue 15, Page 4193-4211, August 2023., 2023
Metagenomics is a powerful tool to track both the population genetics and environmental stressors wildlife encounter across landscapes. This study examines wild bees across an urban gradient to determine gene flow and changes in microbiome. Densely urban areas have lower habitat connectivity and higher pathogen loads indicating regions of immediate ...

Molecular Detection and Differentiation of Arthropod, Fungal, Protozoan, Bacterial and Viral Pathogens of Honeybees

Veterinary Sciences, 2022
The honeybee Apis mellifera is highly appreciated worldwide because of its products, but also as it is a pollinator of crops and wild plants. The beehive is vulnerable to infections due to arthropods, fungi, protozoa, bacteria and/or viruses that manage ...

Molecular histoproteomy by MALDI mass spectrometry imaging to uncover markers of the impact of Nosema on Apis mellifera

PROTEOMICS, Volume 22, Issue 9, May 2022., 2022
Abstract Matrix‐assisted laser desorption/ionization imaging mass spectrometry (MALDI IMS) is a powerful technology used to investigate the spatio‐temporal distribution of a huge number of molecules throughout a body/tissue section. In this paper, we report the use of MALDI IMS to follow the molecular impact of an experimental infection of Apis ...
