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

Nosema ceranae an emergent pathogen of Apis mellifera in Chile [PDF]

Parasitology Research, 2012
The microsporidian Nosema apis and Nosema ceranae have been associated with colony disorders of Apis mellifera and Apis cerana, respectively. N. apis is endemic in South America. Recently, N. ceranae has been detected in Brazil, Uruguay and Argentina. No report of its presence, distribution and prevalence in Chile is available.

Features of microsporidia Nosema apis and Nosema ceranae (Nosema species) development of winter bee (Apis mellifera L.) generation

ScienceRise: Biological Science, 2022
Temperature is one of the main abiotic factors affecting the development of causative agents of nosemosis in the bee's body. The aim of the research. To determine the influence of the winter and summer bee nest temperature (20–22 °C and 35–36 °C, respectively) on the duration of Nosema species development of winter bee generation isolated in hoarding ...

Population Genetics of Nosema apis and Nosema ceranae: One Host (Apis mellifera) and Two Different Histories. [PDF]

PLoS One, 2015
Two microsporidians are known to infect honey bees: Nosema apis and Nosema ceranae. Whereas population genetics data for the latter have been released in the last few years, such information is still missing for N. apis. Here we analyze the patterns of nucleotide polymorphism at three single-copy loci (PTP2, PTP3 and RPB1) in a collection of Apis ...

Parasitological and molecular study of nosemosis in migratory apiaries in Hormozgan Province, southern Iran [PDF]

نامه انجمن حشره‌شناسی ایران, 2023
Nosemosis is a microsporidian disease caused by Nosema ceranae and N. apis and transmitted via oral-fecal and oral-oral routes. It is globally distributed among adult bees in honeybee colonies. Considering the health importance of nosemosis in honeybees,
