UR 406 Abeilles & Environnement, INRA Avignon, France Pollinators face multiple threats including agrochemicals, pathogens, habitat loss and climate change. A major new project PoshBee (Pan-European Assessment, Monitoring and Mitigation of Stressors on the Health of Bees) aims to understand the impacts of these multiple pressures on a range of bee species and develop novel…
Currently, there are four Varroa species identified worldwide, which present a high interspecific and intraspecific variability. The objective of this investigation was to identify the predominant species of Varroa and the effect of thymol on the plasticity of the mite. To determine the species and effect of thymol on the plasticity of the mite, 150…
Dear COLOSS members, On behalf of the CSI Varroa Group leaders (Janja, Nikola and myself) I am posting the final information about our initiative. Most of you probably remember the discussions we had on this subject and this final version is the results of these discussions. With this we are seeking colleagues to act as…
The Dark Side of the Hive – The Evolution of the Imperfect Honey Bee Robin Moritz, Martin Luther University Halle-Wittenberg Robin Crewe, University of Pretoria The first book of its kind to demonstrate the more maladaptative tendencies of a honey bee society Focuses on the perspective and role of the individual worker bee in the…
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…
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…
A PhD student is sought for a project on wild bee – pesticide – parasite interactions within the lab of Robert Paxton at the University of Halle, Germany. The goals of the research are to understand interactions between pesticides and parasites and their joint impact on bees, using a range of bee species. The doctoral…
European foulbrood is a globally distributed brood disease affecting honey bees. It may lead to lethal infections of larvae and, in severe cases, even to colony collapse. Lately, a profound genetic and phenotypic diversity was documented for the causative agent Melissococcus plutonius. However, experimental work on the impact of diverse M. plutonius strains on hosts with…

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,…
