SummaryAdult honey bees are maintained in vitro laboratory cages for a variety of purposes. For example, researchers may wish to perform experiments on caged individually or groups study aspects parasitology, toxicology, physiology under highly controlled conditions, they cage whole frames obtain newly emerged workers known age cohorts. Regardless purpose, must manage number variables, ranging from selection subjects (e.g. bee subspecies) experimental environment temperature and relative...
SummaryHere we cover a wide range of methods currently in use and recommended modern queen rearing, selection breeding. The recommendations are meant to equally serve as standards for both scientific practical beekeeping purposes. basic conditions different management techniques rearing described, including suitable technical equipment. As the success breeding programmes strongly depends on selective mating queens, subchapter is dedicated quality control stations. Recommendations handling...
Abstract Sustainable agriculture requires balancing crop yields with the effects of pesticides on non-target organisms, such as bees and other pollinators. Field studies demonstrated that agricultural use neonicotinoid insecticides can negatively affect wild bee species 1,2 , leading to restrictions these compounds 3 . However, besides neonicotinoids, field-based evidence landscape pesticide exposure is lacking. Bees encounter many in landscapes 4–9 this colony growth development any remains...
SummaryThe survival and performance of 597 honey bee colonies, representing five subspecies 16 different genotypes, were comparatively studied in 20 apiaries across Europe. Started October 2009, 15.7% the colonies survived without any therapeutic treatment against diseases until spring 2012. The duration was strongly affected by environmental factors (apiary effects) and, to a lesser degree, genotypes origin queens. Varroa identified as main cause losses (38.4%), followed queen problems...
Abstract: Although pollinator declines are a global biodiversity threat, the demography of western honeybee ( Apis mellifera ) has not been considered by conservationists because it is biased activity beekeepers. To fill this gap in decline censuses and to provide broad picture current status honeybees across their natural range, we used microsatellite genetic markers estimate colony densities diversity at different locations Europe, Africa, central Asia that had patterns land use. Genetic...
SummaryBeekeepers in Europe, North America and other parts of the world have repeatedly been afflicted by elevated sometimes unexplained colony losses. Multiple factors considered connection with increased winter In addition to national programmes investigating possible causes for honey bee mortality, scientists collaborate at an international level on different aspects health within COLOSS network. Within this network, Working Group 4 explores genetic diversity relation vitality...
SummaryAdaptation of honey bees to their environment is expressed by the annual development pattern colony, balance with food sources and host—parasite balance, all which interact among each other changes in environment. In present study, we analyse patterns over a period two years colonies belonging 16 different genotypes placed areas grouped within six environmental clusters across Europe. The were maintained no chemical treatment against varroa mites. aim study was investigate presence...

Pressures on honey bee health have substantially increased both colony mortality and beekeepers’ costs for hive management across Europe. Although technological advances could offer cost-effective solutions to these challenges, there is little research into the incentives barriers adoption by beekeepers in Our study first investigate willingness adopt Bee Health Card, a molecular diagnostic tool developed within PoshBee EU project which can rapidly assess monitoring changes bees. The based...
Beekeeping is a crucial agricultural practice that significantly enhances environmental health and food production through effective pollination by honey bees. However, bees face numerous threats, including exotic parasites, large-scale transportation, common practices may increase the risk of parasite pathogen transmission. A major threat Varroa destructor mite, which feeds on bee fat bodies transmits viruses, leading to significant colony losses. Detecting defining intervention thresholds...
SummaryDiseases are known to be one of the major contributors colony losses. Within a Europe-wide experiment on genotype—environment interactions, an initial 621 colonies were set up and maintained from 2009 2012. The monitored investigate occurrence levels key pathogens. These included mite Varroa destructor (mites per 10 g bees), Nosema spp. (spore loads species determination), viruses (presence/absence acute bee paralysis virus (ABPV) deformed wing (DWV)). Data 2010 spring 2011 analysed...
The Western honeybees Apis mellifera carnica and A. m. ligustica are closely related subspecies living in neighbouring regions. Metabolism the upper lethal thermal limits crucial physiological traits, adapted evolutionary process to environment climate conditions. We investigated whether samples from these two ecotypes differ traits. standard metabolic rate was higher population only at a high temperature (T ~ 40 °C; dVCO2 = 12 nl s−1; P < 0.05), probably due body (dTthorax 1.5 0.01)....
SummaryHoney bee colonies exhibit a wide range of variation in their behaviour, depending on genetic origin and environmental factors. The COLOSS Genotype-Environment Interactions Experiment gave us the opportunity to investigate phenotypic expression swarming, defensive hygienic behaviour 16 genotypes from five different honey subspecies various conditions. In 2010 2011, total 621 were monitored tested according standard protocol for estimation these three behavioural traits. factors: year,...
With numerous endemic subspecies representing four of its five evolutionary lineages, Europe holds a large fraction Apis mellifera genetic diversity. This diversity and the natural distribution range have been altered by anthropogenic factors. The conservation this heritage relies on availability accurate tools for diagnosis. Based pool-sequence data from 2145 worker bees 22 populations sampled across Europe, we employed two highly discriminative approaches (PCA FST) to select most...
With 2,000 species currently recorded in Europe, bees are a highly diversified and efficient group of pollinating insects. They obtain their nutrients from nectar pollen flowers. However, the chemical composition these resources, especially (e.g., protein, lipid, amino acids, fatty or sterol content), is variable among plant species. While it well-known that show interspecific variation floral choices, there lack information on nutritional requirements different bee We therefore developed...
There is growing evidence that pesticides may be among the causes of worldwide bee declines, which has resulted in repeated calls for their increased scrutiny regulatory assessments. One recurring concern current frameworks biased towards assessing risks to honey bee. This paradigm requires extrapolating toxicity information across species. Most research effort therefore focused on quantifying differences sensitivity However, our understanding how responses vary within a species still very...
Abstract The Tropilaelaps spp. (Mesostigmata: Laelapidae), an ectoparasitic mite originally associated with such Asian giant honey bees as Apis dorsata , A. breviligula and laboriosa has increasingly become a focus of global concern due to its severe effects on Western bee colonies ( mellifera ) recent geographic expansion. This study documents the first reported presence Tr opilaelaps mercedesae in Georgia’s Samegrelo-Zemo Svaneti region, specifically seven caucasica from three apiaries. We...
