Specialized relationships with bacteria often allow animals to exploit a new diet by providing novel set of metabolic capabilities. Bees are monophyletic group Hymenoptera that transitioned completely herbivorous from the carnivorous their wasp ancestors. Recent culture-independent studies suggest distinctive bacterial species inhabits gut honey bee, Apis mellifera. Here we survey microbiotae diverse bee and test whether acquisition these was associated transition herbivory in bees...
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...
Ectoparasitic mites of the genera Varroa and Tropilaelaps have evolved to exclusively exploit honey bees as food sources during alternating dispersal reproductive life history stages. Here we show that primary source utilized by destructor depends on host stage. While feeding adult bees, dispersing V. feed abdominal membranes access fat body reported previously. However, when bee pupae their stage, they primarily consume hemolymph, indicated wound analysis, preferential transfer biostains, a...
The ectoparasitic mite Varroa destructor remains a great threat for the beekeeping industry, example contributing to excessive winter colony loss in Canada. For decades, beekeepers have sequentially used registered synthetic varroacides tau-fluvalinate, coumaphos, amitraz, and flumethrin, leading risk of resistance evolution mites. In addition widespread coumaphos pyrethroids, decline amitraz efficacy has recently been reported numerous regions goals this study were assess Canadian...
The first draft of the honey bee genome sequence and improved genetic maps are utilized to analyze a displaying 10 times higher levels recombination (19 cM/Mb) than previously analyzed genomes eukaryotes. exceptionally high rate is distributed genome-wide, but varies by two orders magnitude. Analysis chromosome, sequence, gene parameters with respect showed that local associated distance telomere, GC content, number simple repeats as described for low-recombining genomes. Recombination does...
Abstract Most pollination in large-scale agriculture is dependent on managed colonies of a single species, the honey bee Apis mellifera . More than 1 million hives are transported to California each year just pollinate almonds and bees trucked across country for various cropping systems. Concerns have been raised about whether such “migratory management” causes undue stress; however date there no longer-term studies rigorously addressing migratory management detrimental health. To address...
Social insect colonies represent distinct units of selection. Most individuals evolve by kin selection and forgo individual reproduction. Instead, they display altruistic food sharing, nest maintenance self-sacrificial colony defence. Recently, self-removal diseased worker ants from their was described as another important kin-selected behaviour. Here, we report corroborating experimental evidence honey bee foragers theoretical analyses. We challenged with prolonged CO(2) narcosis or feeding...
Honeybees form complex societies with a division of labor for reproduction, nutrition, nest construction and maintenance, defense. How does it evolve? Tasks performed by worker honeybees are distributed in time space. There is no central control over behavior there genome on which selection can act effect adaptive change. For 22 years, we have been addressing these questions selecting single social trait associated nutrition: the amount surplus pollen (a source protein) that stored combs...
The ectoparasitic Varroa destructor mite is a major contributor to the ongoing honey bee health crisis. interacts with viruses, exacerbating their pathogenicity. In addition vectoring immunosuppression of developing hosts by has been proposed explain synergy between viruses and mites. However, evidence for immune suppression V. contentious. We systematically studied quantitative effects experimentally introduced mites on gene expression at five specific time points during development hosts....
The ongoing decline of honey bee health worldwide is a serious economic and ecological concern. One major contributor to the are pathogens, including several viruses. However, information limited on biology viruses molecular interactions with their hosts. An experimental protocol test these systems was developed, using injections Israeli Acute Paralysis Virus (IAPV) into pupae reared ex-situ under laboratory conditions. infected developed pronounced but variable patterns disease. Symptoms...
ABSTRACT Resistance to and avoidance of stress slow aging confer increased longevity in numerous organisms. Honey bees other superorganismal social insects have two main advantages over solitary species avoid or resist stress: individuals can directly help each by resource information transfer, they cooperatively control their environment. These benefits been recognised the context pathogen parasite as concept immunity, which has extensively studied. However, we argue that immunity is only a...
Ovarioles are the functional unit of female insect reproductive organs and number ovarioles per ovary strongly influences egg-laying rate fecundity. Social evolution in honeybee (Apis mellifera) has resulted queens with 200-360 total workers usually 20 or less. In addition, variation ovariole among relates to worker sensory tuning, foraging behavior, ability lay unfertilized male-destined eggs. To study genetic architecture number, we performed a series crosses between Africanized European...
The existence of behavioral traits connected to defense against pathogens manifests the importance in evolution social insects. However, very little is known about how pathogen pressure has affected molecular genes involved their innate immune system. We have studied sequence several ants and honeybees. results show high rates both honeybees as measured by ratio amino acid changes silent nucleotide changes, being clearly higher than Drosophila or nonimmunity bees. This conforms our...
Background Ultrasonic vocalizations (USVs) emitted by muroid rodents, including laboratory mice and rats, are used as phenotypic markers in behavioral assays biomedical research. Interpretation of these USVs depends on understanding the significance USV production rodents wild. However, there has never been a study rodent ultrasound function wild comparisons produced lacking to date. Here, we report first comparison captive recorded from same species, Peromyscus californicus. Methodology...
Deformed wing virus (DWV) is an important pathogen in a broad range of insects, including honey bees. Concordant with the spread Varroa, DWV present majority bee colonies and can result either low-level infections asymptomatic bees that nonetheless exhibit increased colony loss under stress, or high-level acute effects on health viability. be transmitted vertically horizontally evidence suggests horizontal transmission via Varroa associated symptomatic infections. Vertical also occurs...
Life-history theory predicts a trade-off between reproductive investment and self-maintenance. The negative association fertility longevity found throughout multicellular organisms supports this prediction. As an important exception, the reproductives of many eusocial insects (ants, bees, termites) are simultaneously very long-lived highly fertile. Here, we examine proximate basis for exceptional relationship by comparing whole-body transcriptomes differently aged queens ant Cardiocondyla...
The health of the honey bee Apis mellifera is challenged by ectoparasitic mite Varroa destructor, and numerous harmful pathogens it vectors. Existing pesticide-based controls are not sustainable. In contrast, one promising approach for improved breeding hygienic bees, capable detecting removing brood that parasitized or diseased. three experiments we find evidence to support hypothesis stock-specific chemical signals induced Deformed Wing Virus, elicit response in bee. By collecting,...
