Parasitoid Wasp Genomes wasps, which prey on and reproduce in host insect species, play important roles plant herbivore interactions, may provide valuable tools the biological control of pest species. The Nasonia Genome Working Group (p. 343 ; see news story by Pennisi ) presents genome three very closely related species: vitripennis, N. giraulti , longicornis . findings document rapid evolution between a endosymbiont that can cause nuclear-cytoplasmic incompatibilities affect speciation.
The first generation of genome sequence assemblies and annotations have had a significant impact upon our understanding the biology sequenced species, phylogenetic relationships among study populations within across informed humans. As only few Metazoan genomes are approaching finished quality (human, mouse, fly worm), there is room for improvement most assemblies. honey bee (Apis mellifera) genome, published in 2006, was noted its bimodal GC content distribution that affected assembly some...
The shift from solitary to social behavior is one of the major evolutionary transitions. Primitively eusocial bumblebees are uniquely placed illuminate evolution highly insect societies. Bumblebees also invaluable natural and agricultural pollinators, there widespread concern over recent population declines in some species. High-quality genomic data will inform key aspects bumblebee biology, including susceptibility implicated viability threats.We report high quality draft genome sequences...
SummaryHoney bee virus research is an enormously broad area, ranging from subcellular molecular biology through physiology and behaviour, to individual colony-level symptoms, transmission epidemiology. The methods used in virology are therefore equally diverse. This article covers those that very particular virological bees, with numerous cross-referrals other BEEBOOK papers on more general methods, as well research. At the root of these realization viruses at their most primary level...
Since the last decade, unusually high honey bee colony losses have been reported mainly in North-America and Europe. Here, we report on a comprehensive pathogen screening Belgium covering 363 colonies that were screened for 18 known disease-causing pathogens correlate their incidence summer with subsequent winter mortality. Our analyses demonstrate that, addition to Varroa destructor, presence of trypanosomatid parasite Crithidia mellificae microsporidian Nosema ceranae are also predictive...
SummarySummaryAmerican foulbrood is one of the most devastating diseases honey bee. It caused by spore-forming, Gram-positive rod-shaped bacterium Paenibacillus larvae. The recent updated genome assembly and annotation for this pathogen now permits in-depth molecular studies. In paper, selected techniques protocols American research are provided, mostly in a recipe-like format that easy implementation laboratory. Topics covered include: working with larvae, basic microbiological techniques,...
This short article presents loss rates of honey bee colonies over winter 2017/18 from 36 countries, including 33 in Europe, data collected using the standardized COLOSS questionnaire. The 25,363 beekeepers supplying passing consistency checks total wintered 544,879 colonies, and reported 26,379 (4.8%, 95% CI 4.7–5.0%) with unsolvable queen problems, 54,525 (10.0%, 9.8–10.2%) dead after another 8,220 (1.5%, 1.4–1.6%) lost through natural disaster. gave an overall rate 16.4% (95% 16.1–16.6%)...
Invasive vectors can induce dramatic changes in disease epidemiology. While viral emergence following geographical range expansion of a vector is well known, the influence have at level host's pathobiome less understood. Taking advantage formerly heterogeneous spatial distribution ectoparasitic mite Varroa destructor that acts as potent virus among honeybees Apis mellifera , we investigated impact its recent global spread on community retrospective study historical samples. We hypothesized...
In this study an important and often neglected aspect of gene expression studies in insects, the validation appropriate reference genes with stable levels between sample groups, is addressed. Although paper selection for honeybee, Apis mellifera L. (Hymenoptera: Apidae) head was tested context bacterial challenge Escherichia coli, work can serve as a resource to help select screen insect any tissue under experimental manipulation. Since it recommended use multiple accurate normalization, we...
Abstract With the Nasonia vitripennis genome sequences available, we attempted to determine proteins present in venom by two different approaches. First, searched for transcripts of a bioinformatic approach using amino acid known hymenopteran proteins. Second, performed proteomic analyses crude N. removed from reservoir, implementing both an off‐line two‐dimensional liquid chromatography matrix‐assisted laser desorption/ ionization time‐of‐flight (2D‐LC‐MALDI‐TOF) mass spectrometry (MS) and...
Abstract Trypanosomatids are increasingly recognized as prevalent in European honey bees ( Apis mellifera ) and by default attributed to one species, Crithidia mellificae Langridge McGhee, 1967. We provide reference genetic ultrastructural data for type isolates of C. ATCC 30254 30862) comparison with two recent from A. BRL SF ). Phylogenetics unambiguously identify strains / a novel taxonomic unit distinct 30254/30862 assign all four lineages clade within the subfamily Leishmaniinae. In...
In this short note we present comparable loss rates of honey bee colonies during winter 2016/2017 from 27 European countries plus Algeria, Israel and Mexico, obtained with the COLOSS questionnaire. The 14,813 beekeepers providing valid data collectively wintered 425,762 colonies, reported 21,887 (5.1%, 95% confidence interval 5.0–5.3%) unsolvable queen problems 60,227 (14.1%, CI 13.8–14.4%) dead after winter. Additionally asked for lost due to natural disaster, which made up another 6,903...
The eusocial societies of honeybees, where the queen is only fertile female among tens thousands sterile worker bees, have intrigued scientists for centuries. proximate factors, which cause inhibition bee ovaries, remain largely unknown; as are factors activation ovaries upon loss and brood in colony. In an attempt to reveal key players regulatory network, we made a proteomic comparison hemolymph profiles workers with completely activated vs. rudimentary ovaries. An unexpected finding this...
This article presents managed honey bee colony loss rates over winter 2018/19 resulting from using the standardised COLOSS questionnaire in 35 countries (31 Europe). In total, 28,629 beekeepers supplying valid data wintered 738,233 colonies, and reported 29,912 (4.1%, 95% confidence interval (CI) 4.0–4.1%) colonies with unsolvable queen problems, 79,146 (10.7%, CI 10.5–10.9%) dead after 13,895 (1.9%, 1.8–2.0%) lost through natural disaster. gave an overall rate of 16.7% (95% 16.4–16.9%),...
Several studies have suggested that covert stressors can contribute to bee colony declines. Here we provide a novel case study and show using radiofrequency identification tracking technology deformed wing virus (DWV) infections in adult honeybee workers seriously impact long-term foraging survival under natural conditions. In particular, our experiments injected with low doses of DWV experienced increased mortality rates, caused start at premature age, the reduced workers' total activity...
In a Belgian pilot study honey bee wax combs from ten hives were analyzed on the presence of almost 300 organochlorine and organophosphorous compounds by LC-MS/MS GC-MS/MS. Traces 18 pesticides found not single sample was free residues. The number residues per ranged 3 to 13, could be categorized as (1) for solely apicultural (veterinary) application, (2) agricultural (crop protection) (3) mixed application. frequencies quantities some environmental pollutants bear us high concerns. Most...
In this short note we present comparable loss rates of honey bee colonies during winter 2015/16 from 29 countries, obtained with the COLOSS questionnaire. Altogether, received valid answers 19,952 beekeepers. These beekeepers collectively wintered 421,238 colonies, and reported 18,587 unsolvable queen problems 32,048 dead after winter. This gives an overall rate 12.0% (95% confidence interval 11.8–12.2%) 2015/16, marked differences among countries. Beekeepers in study assessed 7.6% CI...
The beekeeping sector is suffering from the detrimental effects of climate change, both directly and indirectly. Despite numerous studies conducted on this subject, large-scale research incorporating stakeholders' beekeepers' perspectives has remained elusive. This study aims to bridge gap by assessing extent which stakeholders involved in European beekeepers perceive experience impacts change their operations, whether they had adapt practices accordingly. To end, a mixed-methods including...
