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

Veterinary Medicine and Science, Volume 12, Issue 3, May 2026.
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

The Role of Nosema ceranae (Microsporidia: Nosematidae) in Honey Bee Colony Losses and Current Insights on Treatment [PDF]

Veterinary Sciences, 2022
Honeybee populations have locally and temporally declined in the last few years because of both biotic and abiotic factors. Among the latter, one of the most important reasons is infection by the microsporidia Nosema ceranae, which is the etiological ...

Winter Bottom Beehive Cadavers as a Tool for Assessing Nosema ceranae Infestation Intensity in Honeybee Colonies in Regions with Different Beekeeping Densities in Slovakia [PDF]

Microorganisms
Honeybee (Apis mellifera) colony density is frequently assumed to influence the level of Nosema ceranae infestation in managed colonies. In Slovakia, winter bottom beehive debris (dead worker bees) is routinely collected between January and February ...

Effect of Abscisic Acid (ABA) Combined with Two Different Beekeeping Nutritional Strategies to Confront Overwintering: Studies on Honey Bees’ Population Dynamics and Nosemosis

Insects, 2019
In temperate climates, beekeeping operations suffer colony losses and colony depopulation of Apis mellifera during overwintering, which are associated with biotic and abiotic stressors that impact bees’ health.

Composition and Efficacy of a Natural Phytotherapeutic Blend against Nosemosis in Honey Bees

Sustainability, 2020
Honey bees are essential to sustaining ecosystems, contributing to the stability of biodiversity through pollination. Today, it is known that the failure of pollination leads irremediably to the loss of plant cultures and, as a consequence, inducing food security issues. Bees can be affected by various factors, one of these being Nosema spp.

Development of Enzyme-Linked Immunosorbent and Immunochromatography Assays for Diagnosing Nosema ceranae Infection in Honey Bees [PDF]

Insects
Nosema ceranae (N. ceranae) infection is prevalent globally, causing a decline in bee populations and significant economic losses to apiarists. Although several methods have been proposed for diagnosing Nosema infections, limitations in these methods ...
