Cellular alterations in midgut cells of honey bee...

Beside many beneficial applications in industry, agriculture and medicine, nanoparticles (NPs) released into the environment might cause adverse effects. In the present study, effects of exposure to sublethal concentrations of PbO and CdO NPs, either separately or in combination on honey bee (A. mellifera) workers were assessed. Honey bee workers were fed sugar syrup contained…

Next-generation sequence data demonstrate several pathogenic bee viruses...

Reference: Haddad, N., Horth, L., Al-Shagour, B., Adjlane, N., & Loucif-Ayad, W. (2018). Next-generation sequence data demonstrate several pathogenic bee viruses in Middle East and African honey bee subspecies (Apis mellifera syriaca, Apis mellifera intermissa) as well as their cohabiting pathogenic mites (Varroa destructor). Virus genes, 1-12. RNA viruses are associated with honey bee (Apis…

Searching for nests of the invasive Asian hornet...

Abstract Asian hornets (Vespa velutina) are voracious predators of bees, and are the latest emerging threat to managed and wild pollinator populations in Europe. To prevent establishment or reduce the rate of spread of V. velutina, early detection and destruction of nests is considered the only option. Detection is difficult as their nests are well…

Characterization of Apis mellifera honey from different botanical...

Seven bee honey types identified botanically in terms of their floral origin (Clover, Cedrus, Citrus, Banana, Cotton, Brazilian pepper, and Sun flower), and their geographical regions during 2016 – 2017 have been characterized in comparison with artificial honey. Characterization of honeys was based on their physicochemical properties, antimicrobial activity, heavy metal contents and multi-pesticides residues…

The Fate of Major Royal Jelly Proteins during...

Royal jelly (RJ) is a beehive product with a complex composition, major royal jelly proteins (MRJPs) being the most abundant proteins. Cell culture and animal studies suggest various biological activities for the full-length/native MRJPs. In the field of apitherapy, it is assumed that MRJPs can positively affect human health. However, whenever RJ is administered orally,…
