Worldwide occurrences of honey bee colony losses have raised concerns about bee health and the sustainability of pollination-dependent crops. While multiple causal factors have been identified, seed coating with insecticides of the neonicotinoid family has been the focus of much discussion and research. Nonetheless, few studies have investigated the impacts of these insecticides under field con...

Honey bee mortality has recently been associated with Israeli acute paralysis virus (IAPV), a proposed etiological agent for a new syndrome known as Colony Collapse Disorder. Bees infected with this virus show shivering wings, progress into paralysis, and finally die outside the hive. During the last years, honey bee mortality became a serious problem for Argentinean beekeepers. We herein repor...

Honey bee samples collected between 1995 and 2007 from 12 states were examined for the presence of Nosema infections. Our results showed that Nosema ceranae is a wide-spread infection of the European honey bee, Apis mellifera in the United States. The discovery of N. ceranae in bees collected a decade ago indicates that N. ceranae was transferred from its original host, Apis cerana to A. mellif...

Bee pollen has been used as an apitherapy agent for several centuries to treat burns, wounds, gastrointestinal disorders, and various other diseases. The aim of our study was to investigate the hepatoprotective effects of chestnut bee pollen against carbon tetrachloride (CCI4)-induced liver damage. Total phenolic content, flavonoid, ferric reducing/antioxidant power, and DPPH radical activity m...

Feral honey bee populations have been reported to be in decline due to the spread of Varroa destructor, an ectoparasitic mite that when left uncontrolled leads to virus build-up and colony death. While pests and diseases are known causes of large-scale managed honey bee colony losses, no studies to date have considered the wider pathogen burden in feral colonies, primarily due to the difficulty...

honey is an important product of honey bee that rich in carbohydrate. compounds of honey in each area are different due to weather conditions, type of plants, bee species and management methods. honey quality and effective factors on it can be determined by microbial and physicochemical tests in each area and the producers of fine honey will be supported. in this way, the research has been done...

Bee pollen has been reported to show antioxidant and radical scavenging activities; contributing to anti-inflammatory and gastroprotective properties. Venezuelan honeybee pollen has been little studied, but is consumed because its properties are known from other countries reports. On the basis of these reports, water, ethanol and methanol soluble fractions were prepared from dried bee-pollen co...

Specialized relationships with bacteria often allow animals to exploit a new diet by providing a novel set of metabolic capabilities. Bees are a monophyletic group of Hymenoptera that transitioned to a completely herbivorous diet from the carnivorous diet of their wasp ancestors. Recent culture-independent studies suggest that a set of distinctive bacterial species inhabits the gut of the honey...

Honey bees face new challenges, ranging from climate crisis to emerging pathogens such as Vairimorpha (Nosema) ceranae that synergistically cause a syndrome designated colony collapse disorder (CCD). This study employed metataxonomic approach in order investigate if V. affects gut microbiota (bacteria and fungi) of adult A. mellifera honey well bee bread (BB) stored colonies demonstrating sever...

Abstract This study assessed the conservation status of Saharan honey bee ( Apis mellifera sahariensis ) from southeastern Morocco using 12 microsatellite loci to examine genetic diversity and hybridization with other subspecies. Samples 148 colonies were clustered into seven populations representing expected distribution A. m. intermissa , reference samples two European subspecies, carnica inc...
