Significance Varroa destructor causes considerable damage to honey bees and subsequently the field of apiculture through just one process: feeding. For five decades, we have believed that these mites consume hemolymph like a tick consumes blood, cause harm primarily by vectoring viruses. Our work shows they more directly. externally digest fat body tissue rather than blood. These findings explain failure some previous attempts at developing effectively targeted treatment strategies for...
SummaryVery rapidly after Varroa destructor invaded apiaries of Apis mellifera, the devastating effect this mite prompted an active research effort to understand and control parasite. Over a few decades, varroa has spread most countries exploiting A. mellifera. As consequence, large number teams have worked with organism, developing diversity methods. Often different approaches been followed achieve same goal. The methods made results difficult compare, thus hindering our understanding In...
SummaryA variety of methods are used in honey bee research and differ depending on the level at which is conducted. On an individual level, handling bees, including queen, larvae pupae required. There different for immobilising, killing storing as well determining weight bees. The precise timing developmental stages also important aspect sampling individuals experiments. In order to investigate manipulate functional processes e.g. memory formation retrieval gene expression, microinjection...
Managed honey bee colony losses are of concern in the USA and globally. This survey, which documents rate loss during 2015–2016 season, is tenth report winter losses, fifth summer annual losses. Our results summarize responses 5725 valid survey respondents, who collectively managed 427,652 colonies on 1 October 2015, an estimated 16.1% all USA. Responding beekeepers reported a total 40.5% [95% CI 39.8–41.1%] between April 2015 2016. Total was 26.9% 26.4–27.4%] while 23.6% 23.0–24.1%], making...

Most of the world's crops depend on pollinators, so declines in both managed and wild bees raise concerns about food security. However, degree to which insect pollination is actually limiting current crop production poorly understood, as role species (as opposed honeybees) pollinating crops, particularly intensive areas. We established a nationwide study assess extent pollinator limitation seven at 131 locations situated across major crop-producing areas USA. found that five out showed...
Global trends in pollinator‐dependent crops have raised awareness of the need to support managed and wild bee populations ensure sustainable crop production. Provision sufficient forage resources is a key element for promoting within human impacted landscapes, particularly those agricultural lands where demand pollination service high land use management practices reduced available flowering resources. Recent government incentives North America Europe planting wildflowers benefit...
Declines of pollinators and high mortality rates honey bee colonies are a major concern, both in the USA globally. Long-term data on summer, winter, annual colony losses improve our understanding forces shaping viability pollination industry. Since mass die-offs during winter 2006–2007, generally termed "Colony Collapse Disorder" (CCD), loss surveys have been conducted. These gage among beekeepers all operation sizes, recruited to participate via regional beekeeping organizations, phone...
AbstractIn 1988, a comprehensive review of world bee health was published in Bee World. Intended as an accessible and reliable reference to worldwide status, updates have been at intervals since then, including one devoted viruses. These reviews proved valuable accurate source information on health. The last 10years ago the long-awaited latest series is presented here.
The importance of honey bees to the world economy far surpasses their contribution in terms production; they are responsible for up 30% world's food production through pollination crops. Since fall 2006, U.S. have faced a serious population decline, due part phenomenon called Colony Collapse Disorder (CCD), which is disease syndrome that likely caused by several factors. Data from an initial study investigators compared pathogens affected CCD suggested putative role Israeli Acute Paralysis...
SummaryGreater (Lepidoptera: Pyralidae, Galleria mellonella) and Lesser Achroia grisella) wax moths are ubiquitous pests of honey bee colonies globally. The economic importance has led to a number investigations on moth life history, biology, behaviour, ecology, molecular physiology, control. Despite the apicultural industry, they investigated considerably more as model organism for studies in insect genomics, proteomics, etc. Those studying from an perspective typically use only small total...
SummarySummaryAn understanding of the anatomy and functions internal external structures is fundamental to many studies on honey bee Apis mellifera. Similarly, proficiency in dissection techniques vital for more complex procedures. In this paper, which a prelude other papers COLOSS BEEBOOK, we outline basic techniques.ResumenEl conocimiento de la anatomía y las funciones estructuras internas externas es para muchos estudios sobre abeja miel Del mismo modo, el dominio técnicas disección...
Pollinators, including honey bees, are responsible for the successful reproduction of more than 87% flowering plant species: they thus vital to ecosystem health and agricultural services world-wide. To investigate bee exposure pesticides, 168 pollen samples 142 wax comb were collected from colonies within six stationary apiaries in U.S. states. These analyzed evidence pesticides. Samples taken bi-weekly when each colony was active. Each apiary included thirty colonies, which five randomly...
The in vitro rearing of worker honey bees (Apis mellifera L.) has become an increasingly important method bee research general, and pesticide risk assessment specifically. Authorities from the European Organization for Economic Co-operation Development United States Environmental Protection Agency are requesting data on impacts immature survivorship prior to registering new crop protection products. Those using current protocols have had variable success with survival protocol repeatability....
SummarySmall hive beetles, Aethina tumida, are parasites and scavengers of honey bee other social colonies native to sub-Saharan Africa, where they a minor pest only. In contrast, the beetles can be harmful European subspecies. Very rapidly after A. tumida established populations outside its endemic range, devastating effect this beetle under suitable climatic conditions prompted an active research effort better understand control invasive species. Over decade, has spread almost over entire...
The parasitic mite Varroa destructor has a significant worldwide impact on bee colony health. In the absence of control measures, parasitized colonies invariably collapse within 3 years. synthetic pyrethroids tau-fluvalinate and flumethrin have proven very effective at managing this apiaries, but intensive programs based mainly one active ingredient led to many reports pyrethroid resistance. Europe, modification leucine valine position 925 (L925V) V. voltage-gated sodium channel was...
For honey bees (Apis mellifera), colony maintenance and growth are highly dependent on worker foragers obtaining sufficient resources from flowering plants year round. Despite the importance of floral diversity for proper bee nutrition, urban development has drastically altered resource availability these important pollinators. Therefore, understanding foraged by in urbanized areas is key to identifying promoting that enhance health those environments. In this study, we identified pollen...
The COLOSS BEEBOOK is a practical manual compiling standard methods in all fields of research on the western honey bee, Apis mellifera.The network was founded 2008 as consequence heavy and frequent losses managed bee colonies experienced many regions world (Neumann Carreck, 2010).As world's teams began to address problem, it soon became obvious that lack standardized seriously hindering scientists' ability harmonize compare data colony obtained internationally.In its second year activity,...
The reported high loss rates of managed honey bee colonies have been attributed to diverse stressors including pesticides. Honey larvae can be exposed pesticides in contaminated nectar, pollen and wax. Due the difficulties rearing vitro, research focusing on adult exposure is more common than that larva Herein, we aimed assess acute toxicity five insecticides using an improved vitro method.LC50 LD50 were calculated for at 72 h following a single diet administered when 84 ± 12 old. Solvent...
The effects of chronic exposure to two neonicotinoids (clothianidin and imidacloprid) organophosphates (chlorpyrifos dimethoate) on survival, developmental rate larval weight honey bee larvae reared in vitro were determined. Diets containing chemicals fed with the range concentrations for each compound based published acute toxicity experiments residues found pollen nectar, both components diet.Four controls tested: chlorpyrifos: 0.5, 0.8, 1.2, 8 mg/L; clothianidin: 0.1, 0.4, 2, 10 mg L-1 ;...
