Urbanisation is associated with reduced sp. infection, higher colony strength and higher richness of foraged pollen in honeybees.

Apidologie 2020 8;51(5):746-762. Epub 2020 Apr 8.

School of Biological Sciences, Royal Holloway University of London, Egham, UK.

Bees are vital pollinators, but are faced with numerous threats that include loss of floral resources and emerging parasites amongst others. Urbanisation is a rapidly expanding driver of land-use change that may interact with these two major threats to bees. Here we investigated effects of urbanisation on food store quality and colony health in honeybees () by sampling 51 hives in four different land-use categories: urban, suburban, rural open and rural wooded during two seasons (spring and autumn).

Since its foundation, has steadily gained recognition as a journal that reports results from high-quality scientific research on the biology of bees, and this means Apidae in general, not only on its most prominent species, the Western honey bee, . All started 50 years ago in a conversation between two eminent scientists, Jean Louveaux, director of one of INRA's bee research unit in Bures-sur-Yvette and editor of the French , and Friedrich Ruttner, director of the Bee Research Institute in Oberursel and editor of the German , where they discussed the possibility of merging these two journals to create an international bee research journal. Here, we take 's 50th anniversary as an opportunity to provide our readers with background information on the journal's history, especially on the persons and their contributions along this journey.

Assessing virulence of mites from different honey bee management regimes.

Apidologie 2020 10;51(2):276-289. Epub 2019 Dec 10.

The mite is an important honey bee parasite that causes substantial losses of honey bee colonies worldwide. Evolutionary theory suggests that the high densities at which honey bees are managed in large-scale beekeeping settings will likely select for mites with greater growth and virulence, thereby potentially explaining the major damage done by these mites. We tested this hypothesis by collecting mites from feral bee colonies, "lightly" managed colonies (those from small-scale sedentary operations), and "heavily" managed colonies (those from large-scale operations that move thousands of colonies across the US on a yearly basis).

Fine scale population genetic structure of , an ectoparasitic mite of the honey bee ().

Apidologie 2016 13;2016:1-9. Epub 2016 Jun 13.

is an obligate ectoparasitic mite and the most important biotic threat currently facing honey bees (). We used neutral microsatellites to analyze previously unreported fine scale population structure of , a species characterized by extreme lack of genetic diversity owing to multiple bottleneck events, haplodiploidy, and primarily brother-sister matings. Our results surprisingly indicate that detectable hierarchical genetic variation exists between apiaries, between colonies within an apiary, and even within colonies. Read More

Distance Between Honey Bee Colonies Regulates Populations of at a Landscape Scale.

Apidologie 2016 2;2016:1-9. Epub 2016 May 2.

Department of Entomology, University of Georgia, 413 Biological Sciences Building, Athens, GA 30602 USA.

Inter-colony distance of significantly affects colony numbers of the parasitic mite . We set up 15 apiaries, each consisting of two colonies. Each apiary pair was assigned an inter-colony distance of 0, 10, or 100 m. Read More

Pathogen prevalence and abundance in honey bee colonies involved in almond pollination.

Apidologie 2016;47:251-266. Epub 2015 Oct 21.

Department of Plant Sciences and Plant Pathology, Montana State University, Bozeman, MT 59717 USA ; Institute on Ecosystems, Montana State University, Bozeman, MT 59717 USA.

Honey bees are important pollinators of agricultural crops. Since 2006, US beekeepers have experienced high annual honey bee colony losses, which may be attributed to multiple abiotic and biotic factors, including pathogens. However, the relative importance of these factors has not been fully elucidated. Read More

Establishment risk of the commercially imported bumblebee -can they survive UK winters?

Apidologie 2016;47:66-75. Epub 2015 Jul 21.

School of Biosciences, University of Birmingham, Edgbaston, Birmingham, B15 2TT UK.

Bumblebees are regularly exported to countries outside their native range for the purposes of commercial pollination. In contrast to the tight regulations imposed on biological control introductions, the movement of bumblebees has largely been without risk assessment. This study represents the first formal assessment of establishment risk for in the UK. Read More

Immune responses of honeybees and their fitness costs as compared to bumblebees.

Apidologie 2015;46(2):238-249. Epub 2014 Oct 17.

Department of Zoology, Universitätsplatz 2, Karl-Franzens University of Graz, A-8010 Graz, Austria.

Immune responses of invertebrates imply more than developing a merely unspecific response to an infection. Great interest has been raised to unveil whether this investment into immunity also involves fitness costs associated to the individual or the group. Focusing on the immune responses of honeybees, we use the well-studied insect bumblebee for comparison. Read More

The Architecture of the Pollen Hoarding Syndrome in Honey Bees: Implications for Understanding Social Evolution, Behavioral Syndromes, and Selective Breeding.

Social evolution has influenced every aspect of contemporary honey bee biology, but the details are difficult to reconstruct. The reproductive ground plan hypothesis of social evolution proposes that central regulators of the gonotropic cycle of solitary insects have been coopted to coordinate social complexity in honey bees, such as the division of labor among workers. The predicted trait associations between reproductive physiology and social behavior have been identified in the context of the pollen hoarding syndrome, a larger suite of interrelated traits.

Metabolism and the upper lethal thermal limits are crucial physiological traits, adapted in the evolutionary process to environment and climate conditions. We investigated whether samples from these two ecotypes differ in these traits. Read More

Contribution of honeybee drones of different age to colonial thermoregulation.

Apidologie 2009 Jan;40(1):82-95

Karl-Franzens-Universität Graz, Institut für Zoologie, Universitätsplatz 2, 8010 Graz, Austria.

In addition to honeybee workers, drones also contribute to colonial thermoregulation. We show the drones' contribution to thermoregulation at 5 different experimental temperatures ranging from 15-34 °C. The frequency and the degree of endothermy depended on the drones' local ambient temperature and age. Read More
