Abstract:
Apiculture has become a profitable profession due to the high economic importance of honey and various beehive products. Honeybees are tiny social insects that perform a crucial function in the agricultural field and are necessary for good yields. Honeybees are the biological indicators of environmental health. Unforeseen rapid decrease in honeybee numbers characterized by the departure of honeybees from the colonies and accompanied by the total absence of any dead bees in the hive surrounding and inside it suggests a condition called Colony Collapse Disorder (CCD). Pesticides, pathogens, and other ecological stresses such as nutritional deficiency may add to bee extinction or CCD. Besides this, the exposure to low-level radiofrequency and microwave radiations from mobile phones also have profound undesirable effects on honeybees. Research has shown changes in biology and behaviour which includes some undesirable changes in the biomolecules concentration in honeybees because of radiation exposure. Extremely low-frequency electromagnetic field (ELF- EMF ) also affects honeybee`s immune system and navigation activities. The radiation induces emotional disturbance and genetic disorders in brood which attributes to a decline in the breeding efficiency of bees. The present review is an attempt to compile the causes of CCD and discuss the management practices to be followed by the beekeepers to avoid the devastating loss to them and the planet Earth.

Abstract:
The aim of this study was to determine the Nosema species by microscopic and molecular method and its association with honeybee colony losses (Colony Collapse Disorder) in apiaries of Urmia, Northwest of Iran. For this purpose, honeybee samples were collected from 840 colonies kept in 120 apiaries in five different location of Urmia. The specimens were examined for the presence of Nosema spores. After DNA isolation, the 16S rRNA gene was evaluated using multiplex PCR. Total infection prevalence with the microscopic evaluation was 32% while in PCR test was 58.2%. Nosema positive samples were evaluated by PCR sequencing. Based on the results of PCR, all identified cases were N. ceranae. The obtained sequences were transferred to GenBank/NCBI (samples accession numbers MT001887 and MT001893). The results showed the prevalence of Colony Collapse Disorder like symptoms in the studied honeybee colonies were 13.33%. N. ceranae was detected by PCR in 20.28 % of honeybee colonies with Colony Collapse Disorder like signs. Our findings showed that there was a significant relation between Colony Collapse Disorder and presence of N. ceranae. The results of this study concluded that N. ceranae is the only specie that affects the honeybees which may have an important role in the occurrence of collapse of bee families and depopulation of hives in this area.

Abstract:
Bees play a vital role in saving environment as they are the paramount agricultural pollinators and are the prior pollinators in the tropical ecosystem. Now a days, bees are in trouble as they are suffering from a mysterious condition known as colony collapse disorder in which honeybees leave their hives but fail to return back there because of the environmental activities done by the human. It caused a tremendous drop in the number of bees around the globe. The main reasons behind it are massive use of pesticides in agriculture, trading of bees by the humans and electromagnetic radiation emitted by the portable devices. In this research paper, importance of honeybees and the reason behind their disappearance has been studied.

Abstract:
Honeybees are the most prevalent insect pollinator species; they pollinate a wide range of crops. Colony collapse disorder (CCD), which is caused by a variety of biotic and abiotic factors, incurs high economic/ecological loss. Despite extensive research to identify and study the various ecological stressors such as microbial infections, exposure to pesticides, loss of habitat, and improper beekeeping practices that are claimed to cause these declines, the deep understanding of the observed losses of these important insects is still missing. Honeybees have an innate immune system, which includes physical barriers and cellular and humeral responses to defend against pathogens and parasites. Exposure to various stressors may affect this system and the health of individual bees and colonies. This review summarizes and discusses the composition of the honeybee immune system and the consequences of exposure to stressors, individually or in combinations, on honeybee immune competence. In addition, we discuss the relationship between bee nutrition and immunity. Nutrition and phytochemicals were highlighted as the factors with a high impact on honeybee immunity.

Abstract:
In the last decade there has been an increase of interest and concern for the lives and well being of honeybees. With the onset of colony collapse disorder (CCD) in 2006 where we saw the disappearance of millions of bees from North America and Europe for seemingly unknown reasons, people began to realize just how important honeybees are, not only to advanced methods of agricultural production, but also our ecological futures. This article brings to light the varied relationships that have materialized between humans and honeybees, from mid 20th century scientific discoveries, to contemporary urban beekeeping projects that seek to bring ‘nature’ into the city in order to help “save the honeybee.” It aims to articulate moments of enchantment that occur in the presence of honeybees, moments that inspire a deeper understanding of the ecological processes and spiritual dispositions that configure our place on Earth amongst the family of things. While drawing primarily from recent articles and books that sit within the emerging field of multispecies ethnography, this article also draws from, and is inspired by, recent work in philosophy, environmental sciences, and human ecology.

Abstract:
AbstractDuring the 2000s, the problem of pesticide poisoning of honeybees seemed to be almost solved. The number of cases has decreased in comparison to the 1970s. The problem of acute honeybee poisoning, however, has not disappeared, but instead has transformed into a problem of poisoning from ‘traditional’ pesticides like organophosphorus pesticides or pyrethroids, to poisoning from additional sources of ‘modern’ systemic neonicotinoids and fipronil. In this article, the biological activity of pesticides was reviewed. The poisoning symptoms, incident definitions, and monitoring systems, as well as the interpretation of the analytical results, were also reviewed. The range of pesticides, and the detected concentrations of pesticides in poisoned honeybee samples, were reviewed. And, for the first time, cases of poisoning related to neonicotinoids were reviewed. The latter especially is of practical importance and could be helpful to analysts and investigators of honeybee poisoning incidents. It is assumed that secondary poisoning induced by plant collected materials contaminated with systemic pesticides occurs. Food stored in a hive and contaminated with systemic pesticides consumed continuously by the same generation of winter bees, may result in sub-lethal intoxication. This leads to abnormal behaviour identified during acute intoxication. The final result is that the bees discontinue their social role in the honeybee colony super organism, and colony collapse disorder (CCD) takes place. The process described above refers primarily to robust and strong colonies that were able to collect plenty of food due to effective plant protection.

Abstract:
Nowadays, colony collapse disorder extensively affects honeybees. Insecticides, including acetamiprid, are considered as critical factors. As prevalent probiotics, we speculated that supplementation with lactic acid bacteria (LAB) could alleviate acetamiprid-induced health injuries in honeybees. Apilactobacillus kunkeei was isolated from beebread; it significantly increased the survival of honeybees under acetamiprid exportation (from 84% to 92%). Based on 16S rRNA pyrosequencing, information on the intestinal bacteria of honeybees was acquired. The results showed that supplementation with A. kunkeei significantly increased survival and decreased pollen consumption by honeybees under acetamiprid exportation. Under acetamiprid exportation, some opportunistic and pathogenic bacteria invaded the intestinal regions. Subsequently, the community richness and diversity of symbiotic microbiota were decreased. The community structure of intestinal bacteria was changed and differentiated. However, with the supplementation of A. kunkeei, the community richness and community diversity of symbiotic microbiota showed an upward trend, and the community structure was stabilized. Our results showed that A. kunkeei alleviated acetamiprid-induced symbiotic microbiota dysregulation and mortality in honeybees. This demonstrates the importance of symbiotic microbiota in honeybees and supports the application of Apilactobacillus kunkeei as probiotics in beekeeping.

Abstract:
Under vintrarna 2006/2007 och 2007/2008 vittnade man i USA om storskaliga förluster avhonungsbin (Apis mellifera). Gemensamma symptom för dessa förluster var att arbetarbinförsvann från kolonierna fastän det fanns rikligt med mat och inga tecken på infektion av någonparasit. Fenomenet fick namnet Colony Collapse Disorder (CCD) eftersom det slutgiltigastadiet var att kolonierna kollapsade. Denna översiktstudie ämnar till att reda ut begreppetCCD och se över vilka potentiella orsaker den rådande forskningen föreslår och vad man harkommit fram till sedan utbrottet 2006. Resultaten indikerar att det antagligen inte är en ensamfaktor bakom CCD utan att flera faktorer samverkar. Det finns ett antal hot mot bina medsymptom som liknar CCD och som antas bidra till försvinnandet. Ett hot är det parasitiskakvalstret Varroa destructor som förutom att det suger binas hemolymfa även agerar vektor åtflera CCD-förknippade patogener som Nosema ceranae och Israeli acute paralysis virus(IAPV). Dessutom sänker V. destructor binas immunförsvar vilket gör att virus som överförsvia kvalstret replikeras snabbare och blir dödligare. Man har även visat att vanligt förekommandebekämpningsmedel kan göra bina mer mottagliga för sjukdomar. Där hittade man ettsignifikant samband med just N. ceranae vilket är i enlighet med teorin om att flera faktorersamverkar. I nuläget bidrar CCD fortfarande till bidöd men är inte lika akut som 2006/2007.Istället är det andra hot såsom biodlares svårighet att behandla invasion av varroakvalster,kalla vintrar och att bisamhällen svälter ihjäl för att de invintras i för små populationer, som ärett större hot än CCD.

Abstract:
Nosema ceranae, a microsporidian, has been given much attention in recent years as it has been linked with Colony Collapse Disorder (CCD), which leads to the sudden deaths of honey bee colonies. It has been described that many pathogenic organisms secrete virulence factors in order to hijack its host`s cellular functions, but in most cases the underlying mechanisms of this process still remains to be deciphered. Cornman et al. (2009) have identified in N. ceranae a list of putative effector proteins (called secretome) destined to be secreted into the host, and I have taken this list for further investigation using a bioinformatical and experimental approaches. The principal aim of this project was to generate a N. ceranae ORFeome for genes predicted to be secreted, elucidate the function of effector candidates important for N. ceranae biology and/or pathogenicity, as well as to investigate any interactions between N. ceranae proteins and its host utilising two eukaryotic model organisms, budding yeast, S. cerevisiae, and fruit fly, D. melanogaster. A library of S. cerevisiae strains expressing N. ceranae proteins was generated utilising the Gateway® technology, and phenotypic and localisation screens were undertaken to investigate the N. ceranae secretome. Two N. ceranae ORFs, NcORF-15 (NcORF-02039) and NcORF-16 (NcORF-01159) encoding a putative thioredoxin and a hexokinase, respectively, were subjected to yeast complementation assays in order to assess their catalytic activity. NcORF-15, the putative thioredoxin, was able to rescue the sensitive phenotype of S. cerevisiae Δtrx2 under oxidative stress, whereas NcORF-16, the putative hexokinase, did not complement YSH7.4-3C, a triple knockout lacking hexokinase activity. A third N. ceranae effector candidate NcORF-4 (NcORF-00654), a putative proteasome subunit, was investigated for its nuclear localisation and protein interactions in both S. cerevisiae and D. melanogaster.

Dissertação de Mestrado Integrado em Medicina Veterinária
A morte e o desaparecimento de colónias de abelhas (Apis mellifera) e mesmo de apiários inteiros têm vindo a preocupar cientistas do mundo inteiro. Várias doenças e outros fatores foram associados ao colony collapse disorder (distúrbio do colapso das colmeias). Os ácaros da espécie Varroa destructor são apontados como um dos principais culpados deste problema.Com o crescente aparecimento de resistência aos acaricidas por parte de Varroa sp., devido à utilização sucessiva da mesma molécula ou por má aplicação destes, criou-se uma necessidade de desenvolver novos métodos de combate a este parasita. A utilização de protocolos de tratamento combinando mais de um acaricida, têm-se apresentado como uma boa alternativa à utilização convencional de apenas um medicamento. O principal objetivo deste estudo realizado no Posto Apícola da Tapada da Ajuda (em Lisboa), consistiu em determinar a eficácia e qual o melhor método de aplicação de dois acaricidas homologados em Portugal no controlo de Varroa destructor. Assim, foram estabelecidos dois grupos de colónias para o estudo, um deles em que foi aplicado em primeiro lugar timol (Thymovar®) e depois o fluvalinato (Apistan®) (TA; n=10) e outro em que se aplicou em primeiro lugar o fluvalinato e depois o timol (AT; n=10). Para determinar o valor de eficácia de tratamento, foi aplicado um terceiro acaricida como controlo (amitraz). Foi contabilizada a queda de Varroas três vezes por semana, do momento de aplicação do primeiro acaricida, até perfazer duas semanas após a aplicação do acaricida controlo. A média de eficácia do grupo TA foi de 87,3%, apresentando valores mínimo e máximo de 72,6% e 97,9%, respetivamente. O grupo AT apresentou média de eficácia 91,2%, com valores entre 72,1% e 99%. Comparando os valores de média dos dois grupos, conclui-se que não apresentaram diferença significativa (p=0,304), aplicando um teste-t não emparelhado. Foram medidas as temperaturas mínimas e máximas, e a partir daí a temperatura média. Vários picos de valores de queda de Varroa são consistentes com o aumento da temperatura, o que indica haver uma possível relação entre estes. Apesar de não ter sido encontrada diferença entre os dois grupos, os valores de eficácia obtidos foram superiores aos obtidos nos últimos anos em Portugal, aquando da aplicação de apenas um acaricida. Podemos assim concluir que estes protocolos terapêuticos são ambos uma boa escolha para o controlo de Varroa destructor, de preferência juntamente com outras técnicas de maneio que reduzam a reprodução destes ácaros.
ABSTRACT - Efficacy evaluation of a new strategy against Varroa destructor in honey bees (Apis mellifera) in Portugal: combined treatment with approved acaricides - Death and disappearance of bee colonies (Apis mellifera) and entire apiaries increased worldwide. Several diseases have been associated to the Colony collapse disorder, and the mite Varroa destructor infestation has been noted as one of the main causes of the problem. The increasing emergence of tolerance to acaricides by Varroa sp., due to successive use of the same molecule or wrong use of these chemicals, lead to the development of new methods to control this parasite. New protocols combining more than one acaricide have shown to be a good alternative to conventional use of only one drug. The main objective of this study accomplished at Posto Apícola in Tapada da Ajuda (Lisbon, Portugal), was to determine the efficacy and the best method to fight Varroa destructor using two acaricides approved in Portugal. Thus, two groups of colonies were established, one that used first thymol (Thymovar®) and then fluvalinate (Apistan®) (TA, n=10), and the other using fluvalinate first and then thymol (AT, n=10). To assess the efficacy of treatment, a third treatment with amitraz was used as control. Mites fall was measured three times in a week, during the assay, starting at the first treatment and ending two weeks after the control treatment. The mean efficacy of the treatment protocol for TA group was 87.3%, with 72.6% as a minimum and 97.9% as a maximum. The group AT presented a mean efficacy of 91.2%, with values between 72.1% and 99%. It was concluded, after the statistical analysis with unpaired T-test, that no significant difference (p=0,304) was found between the two groups. The average temperature was calculated with measurement of minimum and maximum daily temperature, and indicated a possible link between these and mite population profile, as several peaks of Varroa fall were consistent with temperature peaks. Although no difference was found between the groups, efficacy results were higher than others obtained in the last years in Portugal, when only one acaricide is used. So, both protocols are a good choice to fight Varroa destructor, along with management techniques that reduce the reproduction of these mites.

Abstract:
Brevibacillus laterosporus (B. laterosporus) is a pathogen difficult to distinguish from Paenibacillus larvae (P. larvae), and contributes to Colony Collapse Disorder (CCD) of honeybees. To develop a biocontrol agent to limit its presence, bacteriophages were isolated from Utah County soil samples and used to infect B. laterosporus isolated from Utah County honey and larvae samples. Since CCD is prevalent in Utah beehives, bacteriophage that infect and lyse B. laterosporus may be isolated and characterized. Pathogens were isolated from soil samples, and 16S rRNA gene tests initially identified the strains as P. larvae. Bacteriophages were isolated, purified, and amplified sufficiently to obtain images by electron microscope and genome sequencing by 454 pyrosequencing. Genomes were annotated with DNA Master, a Multiple Document Interface (MDI) program. Open reading frames (ORF's) were compared to the National Center for Biotechnology Information's (NCBI) database of primary biological sequence information via the Basic Local Alignment Search Tool (BLAST) algorithm. Later testing determined the pathogen to actually be B. laterosporus. Plaques demonstrated lytic activity, and electron microscopy revealed bacteriophages of the myoviridae family. The five sequenced genomes were composed of linear dsDNA ranging from 45,552 to 58,572 base pairs in length, 92 to 100 genes per genome, and a 38.10% to 41.44% range of G + C content. Discovering and describing new bacteriophages is a reasonably reproducible process and contributes to appreciating the diverse relationships between bacteriophage, bacteria, and eukaryota. Scientific facilitation of the bacteriophages role in limiting detrimental bacteria may contribute as an adjunctive therapy for CCD.

The ectoparasitic mite Varroa destructor that parasitize honey bees has become a global problem. Although this mite is unlikely to, by itself, cause the mortality of hives, it plays an important role as a vector for many viral diseases. These diseases are identified as some of the most important reasons for the Colony Collapse Disorder. The effects of V.destructor infestation are disparate in different parts of the world. Greater morbidity - in the form of colony losses - has been reported in colonies of European honey bees (EHB) in countries of Europe, Asia and North America. However, this mite has been in Brasil for many years and there are no reports of losses of Africanized honey bees (AHB) colonies. Studies carried out in Mexico showed that some resistance behaviors to the Varroa mite - especially grooming and hygienic behavior - appear to be different in each subspecies. Could those mechanisms explain why the AHB are less susceptible to Colony Collapse Disorder? In order to answer this question, we propose a mathematical model based on differential equations, to analyze the role of these resistance mechanisms in the overall health of the colony, and it’s ability to face environmental challenges.
Os ácaros ectoparasitas Varroa destructor, que parasitam as abelhas tornaram-se um problema global. Embora seja pouco provável que estes ácaros, por si só, provoquem a mortalidade das colmeias, eles desempenham um importante papel como vetor de muitas doenças virais. E estas doenças são identificados como algumas das mais importantes razões para a Desordem do Colapso das Colônias. Os efeitos da infestação do V.destructor são distintas em diferentes partes do mundo. Maiores mortalidades de colônias têm sido relatadas em colônias de abelhas européias (AE) em países da Europa, Ásia e América do Norte. No entanto, este ácaro está presente no Brasil já por muitos anos e não existem relatos de perdas em colônias das abelhas africanizadas (AA). Estudos realizados no México mostraram que alguns comportamentos de resistência ao ácaro Varroa - especialmente o grooming e o comportamento higiênico - são diferentes em cada uma das subespécie. Poderiam então esses mecanismos explicar por que as abelhas africanizadas são menos suscetíveis à Desordem do Colapso das Colônias? A fim de responder a esta pergunta, propomos um modelo matemático baseado em equações diferenciais, com o objetivo de analisar o papel desses mecanismos de resistência na saúde geral da colônia e na capacidade da colônia para enfrentar desafios ambientais.

Det här arbetet handlar om tambins inverkan på naturligt förekommande pollinatörer. Min frågeställning berör: tillgången på näring, hälsotillståndet och populationsnivån hos naturligt förekommande pollinatörer i förhållande till tambins närvaro. Det som framkommit av den här litteraturstudien är att introducerade tambin leder till att naturligt förekommande pollinatörer minskar i antal kring bikuporna, en del arter söker föda på andra blommor eller senare på dygnet än tidigare. Den minskade tillgången på föda som denna konkurrens innebär har en negativ inverkan på humlors kroppsstorlek och därmed deras överlevnad. Samt att tambin kan föra över patogener så som varroakvalster, nosemasjuka och deformed wing virus till humlor vilket leder till minskad livslängd och sämre fortplantning.
This study is about the impact of honeybees on native pollinators. My questions concerns: availability of food, the health and population level of native pollinators in relation to the presence of honeybees. What has emerged from this literature review is that the introduction of honeybees lead to a decline in numbers of bee and bumblebee pollinators in proximity of the hives and also alters their behaviour, some species choose to forage on other flowers, or later in the day than before honeybees where introduced. The reduced availability of food that this competition induces has a negative impact on the size of bumblebees body’s and thus their survival. What was also discovered was that honeybees can transfer pathogens such as varroa mites, the microsporidium Nosema ceranae and deformed wing virus to bumblebees, leading to reduced life expectancy and poor propagation.

Abstract:
Bee crisis is threatening worldwide food security. Pesticides are extensively used in the agricultural zone. Unfortunately, these pesticides cause severe toxicity toward pollinators than the target pests such as honeybees. This review summarizes the different studies related to pesticide hazards of bees. This paper reported risks of pesticides neurological and physiological poisoning toward honeybees. Pesticides act as poison and ruin vital functions involved in leaning and cognition, behavior and, the body physiological mechanisms. Many laboratory and field research data evaluated the lethal and sub-lethal poisoning on bee foraging dance, learning, and memory abilities of honeybees. Insecticide residues are detected in bee bodies and LD50 and LC50 values evaluated. It is also studied that in honeybees systemic insecticide residues and, its metabolite adulterated in their body during foraging activities. Similarly, pesticide-contaminated food stored in a hive consumed continuously by honeybees may cause sub-lethal toxicity effects. Which causes anomalous bee social behavior and ultimately leads to colony collapse disorder. If population of pollinator decline it will disturb the food chain and leads to food crisis. This review emphasized causes of bee decline with the emergence of pesticides in agricultural domains.

Abstract:
The concept of the political opportunity structure from social movement studies has undergone various expansions, including the development of a theory of the industry opportunity structure in social movement studies and of the intellectual opportunity structure in science and technology studies. The chapter then discusses how the theory of the political opportunity structure can be further developed through systematic consideration of its epistemic dimension. This dimension has two pairs of basic features: the level of scientization (the use of technical decision-making criteria) and the extent of public participation in the policy process, and the epistemic culture of risk evaluation (the preference of government regulators for narrow or inclusive methods) and the degree of precautionary preference when making decisions in situations of uncertain evidence. The framework is applied to cases of colony collapse disorder, the regulation of genetically modified food, nanotechnology, the smart meter movement, and climate science denialism.

Abstract:
O Distúrbio do Colapso das Colônias (Colony Collapse Disorder, CCD) é um fenômeno associado ao desaparecimento repentino de abelhas melíferas em colônias manejadas. Registrado nos EUA desde 2006, o CCD tem como possíveis causas desde as variações climáticas, uso incorreto de defensivos químicos até pragas e doenças. Neste sentido, soluções computacionais criativas podem contribuir para um melhor entendimento da sanidade e do bem-estar das abelhas. Neste artigo, aplicamos modelos de aprendizagem de máquina para detectar anomalias em padrões acústicos de abelhas melíferas africanizadas (Apis mellifera L.) e em padrões de temperatura e de umidade sazonais internas em colmeias com abelhas de raça europeia. Três modelos preditivos foram implementados: Modelo de Mistura de Gaussianas (GMM), Máquina de Aprendizado Extremo (ELM) e Máquina de Vetor de Suporte para uma classe (OC-SVM). Utilizamos datasets com dados de temperatura e umidade internas de duas colmeias de abelhas melíferas localizadas nas cidades de Bournemouth (Inglaterra) e Würtzburg (Alemanha) e um dataset com áudio de uma colônia melífera em Fortaleza-CE (Brasil). Para temperatura e umidade, os melhores resultados ocorreram para anomalias sazonais, nas quais o algoritmo ELM alcançou uma acurácia média de 92,6%. Para os áudios, destacamos o algoritmo GMM (acurácia média de 84,9%) na detecção de ausência da rainha.
