    Full Text Available O presente trabalho foi realizado com o objetivo de verificar até que altura as abelhas africanizadas deslocam-se para a coleta de alimentos e se existe preferência destas abelhas por alguma altura. Instalou-se, num eucalipto de mais de 30m, um sistema de roldana que possibilitava a colocação de armadilhas a diferentes alturas, para a captura dos insetos que ali fossem se alimentar. As médias do número de abelhas coletadas em sete alturas (de 0 a 30m decresceram com o aumento da altura e o melhor ajuste foi o de um polinômio linear. No detalhamento da primeira altura (0-5m, que apresentou a maior concentração de abelhas, o melhor ajuste foi o de um polinômio de segundo grau, com um máximo entre 1 e 2m, apesar da maior media observada corresponder à altura de 3m. Não ocorreram diferenças (P>0,05 entre as médias do número de abelhas coletadas nos períodos da manhã e da tarde.

    DAVID W ROUBIK

    Full Text Available Pocos estudios han considerado la dinámica de poblaciones de abejas en bosques o hábitats no alterados por el hombre. La presencia de abejas silvestres Africanizadas de Apis mellifera (Apidae fue estudiado por 10-17 años en áreas previamente sin esta especie. Aquí presento e interpreto resultados de tres bosques neotropicales: Guyana Francesa, Panamá y Yucatán, México (5° a 19° N. latitud. La abeja Africanizada exótica no produjo efecto negativo en las abejas nativas, incluyendo especies altamente sociales y solitarias. Diferencias mayores a través del tiempo fueron encontradas en la abundancia de las abejas de miel en flores cerca de hábitat con mayor grado de disturbio, comparado con el bosque espeso. Al nivel poblacional, muestreado en bloques de nidos trampa, en flores o con trampas ultravioletas de insectos, no hubo disminución pronta de abejas, y sí hubo una población relativamente estable o sinusoidal. Sin embargo, las abejas nativas cambiaron su hora de buscar provisiones o su selección de especies florales. Una conclusión principal es que esta competencia por los recursos es ‘silenciosa';, en las áreas florísticamente ricas estudiadas, porque las mismas abejas compensan con su comportamiento. Otros factores rigen sus poblaciones.Very little effort has been made to investigate bee population dynamics among intact wilderness areas. The presence of newly-arrived feral Africanized honey bee (AHB, Apis mellifera (Apidae, populations was studied for 10-17 years in areas previously with few or no escaped European apiary honey bees. Here I describe and interpret the major results from studies in three neotropical forests: French Guiana, Panama and Yucatan, Mexico (5° to 19° N. latitude. The exotic Africanized honey bees did not produce a negative effect on native bees, including species that were solitary or highly eusocial. Major differences over time were found in honey bee abundance on flowers near habitat

    2000-05-01

    Full Text Available The introduction of the African bees (Apis mellifera scutelata in Brazil and their expansion in the American Continent created the opportunity to study the process of species adaptation in a new environment. In that process, within intra-specific variability, normalising selection can favour individuals that present a better adaptative morphology and they will constitute the most frequent type found in the population. To test that hypothesis morphometric analyses in samples of colonies of africanized bees and in samples of the populations were performed. The development of the colonies was also evaluated in terms of the amount of their brood, honey and pollen. Analysis of the data indicates that more developed colonies are formed by individuals closer to the population average with concerning morphological traits.A introdução das abelhas africanas (Apis mellifera scutelata no Brasil e sua expansão pelo Continente Americano criou a oportunidade de se estudar o processo de adaptação de uma espécie em um novo ambiente. Nesse processo, dentro da variabilidade intra-específica, a seleção normalizante pode favorecer os indivíduos que apresentam uma morfologia mais adaptativa, os quais constituirão o tipo mais freqüente encontrado na população. Para testar essa hipótese foram feitas análises morfométricas em amostras de colônias de abelhas africanizadas e em amostras da população. Também foi avaliado o desenvolvimento das colônias em termos da quantidade de cria, mel e pólen. A análise dos dados mostrou que as colônias que mais se desenvolveram são formadas por indivíduos mais próximos da m��dia da população quanto às características morfológicas.

    alergenos del veneno, actúa como agente bloqueador que puede provocar parálisis respiratoria. La apamina representa cerca del 2% del veneno total; es menos tóxica que los compuestos anteriores y se comporta como neurotoxina de acción motora; además de desencadenar un efecto cardioestimulante parecido al de las drogas adrenérgicas, tiene propiedades antiarrítmicas. Un 2% del veneno lo constituye el péptido MCD (Mast Cell Degranulation o factor degranulador de los mastocitos, uno de los compuestos responsables de la liberación de histamina y serotonina. Adicionalmente, se han identificado compuestos como fosfatasa ácida, norepinefrina, dopamina e histamina. En esta revisión se exponen aspectos relacionados con la conformación y función del aparato picador, con la composición y acción del veneno, con el comportamiento y los hábitos de las abejas y, finalmente, con las medidas de manejo y tratamiento de sus picaduras; se procuró hacer una mirada comparativa de esos aspectos aplicados a las abejas europeas y a las africanizadas.

  8. Abelhas africanizadas Apis mellifera scutellata Lepeletier, 1836 (Hymenoptera: Apidae: Apinae exploram recursos na floresta amazônica? Do Africanized honeybees explore resources in the amazonian forest?

    Marcio Luiz de Oliveira

    2005-09-01

    Full Text Available As abelhas africanas (Apis mellifera scutellata foram trazidas para o Brasil na década de 1950 e, por acidente, cruzaram-se com outras subespécies de abelhas melíferas européias introduzidas no século XIX. Isso proporcionou o surgimento de híbridos com características predominantes das abelhas africanas, tais como rusticidade e maior capacidade de enxamear, o que lhes permitiu uma rápida adaptação e expansão por quase todo continente americano. Até hoje existem controvérsias se essas abelhas, denominadas africanizadas, causam algum impacto sobre a fauna de abelhas nativas. Nas Américas, as africanizadas estão restritas a regiões de baixas altitudes e de invernos amenos; no Brasil, ocorrem principalmente em áreas urbanas e formações vegetacionais abertas ou adulteradas, sendo dificilmente vistas ou coletadas no interior de florestas densas como a amazônica. Diante dessa observação, diversas iscas foram disponibilizadas no interior de fragmentos de florestas e de florestas contínuas na Amazônia central, para testar se operárias de abelhas africanizadas seriam capazes de penetrar nos mesmos. Nenhuma operária foi vista visitando as iscas na floresta contínua ou mesmo nos fragmentos de floresta, ocorrendo visitas somente nas áreas desmatadas e capoeiras próximas. Esse resultado, além de indicar a inexistência de competição por recursos com as abelhas nativas no interior da floresta amazônica, também indica que uma apicultura em grande escala na região seria inviável, uma vez que a floresta não é sequer visitada por essas abelhas.The African honeybees (Apis mellifera scutellata were introduced accidentally to Brazil in 1956 where it subsequently interbred with other subspecies of European honeybee here introduced in the 19th century. This resulted in hybrids with predominantly African honeybee characteristics, such as higher capacity of swarming and survival in inhospitable conditions, allowing them to adapt

    Full Text Available Introducción: El polen cosechado de las explotaciones apícolas puede verse colonizado con hongos potencialmente toxigénicos durante su producción o almacenamiento, cuyas toxinas pueden tener consecuencias graves sobre la salud de las personas que lo consuman. El objetivo del presente trabajo fue cuantificar el grado de contaminación con hongos en 19 muestras de polen recolectado por las abejas, obtenidas en la ciudad de León, Gto. Método: 19 muestras de polen en diferentes presentaciones comerciales fueron obtenidas en tiendas naturistas de León, Gto., y fueron procesadas por triplicado colocando 100 gránulos sobre el medio de cultivo Papa Dextrosa Agar, e incubados por siete días a 25 °C. Al final del período de incubación se cuantificó el número de gránulos colonizados por los diferentes hongos. Resultados y Discusión: Los resultados mostraron que las tres muestras con mayor contaminación de hongos (98, 100 y 100 % fueron manejadas a granel, resultado similar al obtenido en un estudio previo realizado en 2007 con muestras recolectadas en la ciudad de Irapuato, Gto. Por otro lado, la contaminación de las muestras empacadas en envases de plástico duro (con y sin sellos en sus tapas tendieron a ser bajas, en contraste con lo encontrado en el estudio previo ya citado, donde hubo muestras envasadas de esa forma con más del 90 % de contaminación, lo que indica que el grado de contaminación no es consecuencia solamente de la forma de envasar el polen. La incidencia de los hongos encontrados fue en general baja: Aspergillus (3.6 %, Alternaria (3.6 %, Mucor (3.1 %, Fusarium (2.9 %, Penicillium (2.9 % y Rhizopus (0.7 %, habiéndose encontrado dentro del género Aspergillus la especie A. flavus, la cual puede incluir cepas capaces de producir aflatoxinas. Esta especie fue detectada en 4 de las 19 muestras analizadas, con incidencias de 27, 14, 10 y 1 %, las cuales fueron más altas que las encontradas en el estudio previo hecho en

    Full Text Available En el Parque Nacional del Teide (Tenerife, Islas Canarias se autoriza, cada primavera, la introducción de unas 3000 colmenas de abeja doméstica (Apis mellifera, Apidae. Esto implica que unos 100 millones de abejas melíferas compiten por néctar y polen con la fauna polinizadora nativa (insectos, aves y lagartos de este ecosistema peculiar de alta montaña. Si tenemos en cuenta que A. mellifera es considerada como un polinizador poco eficaz, la masiva presencia de abejas domésticas puede además incidir negativamente tanto en la producción de frutos y semillas como en la viabilidad de las semillas y el vigor de las plántulas. El objetivo de este artículo es señalar las consecuencias ecológicas de la introducción de A. mellifera en la red de interacciones mutualistas en esta área protegida (con un elevado porcentaje de especies endémicas, además de revisar el impacto de la abeja doméstica sobre la flora y fauna nativa en otros sistemas insulares. Los resultados obtenidos muestran que la diversidad de polinizadores disminuye sustancialmente tras la introducción de A. mellifera. Además, se detecta una reducción significativa en la eficacia reproductiva de aquellas plantas (Echium wildpretii, Spartocytisus supranubius frecuentemente visitadas por A. mellifera. Por todo ello, y en base a los resultados obtenidos, se recomienda eliminar completamente la presencia de colmenas en el interior del Parque Nacional del Teide con el fin de proteger su flora y fauna endémica.

(Hymenoptera Apidae, coletados na natureza, durante 16 anos (1981 a 1996, em Jaboticabal, Estado de São Paulo e arredores. Durante a coleta foram feitas avaliações sobre o enxame quanto à: localização, posição (favos expostos ou em cavidades, presença de rainha, defensividade, áreas de cria e alimento e quantidade de abelhas presentes. Foi observada a posição dos favos em relação à entrada da colônia, classificando-os em perpendicular e paralelo. Observou-se que metade dos enxames (51,4% foi coletada dentro do Câmpus da Faculdade de Ciências Agrárias e Veterinárias de Jaboticabal - Unesp, especialmente na área de reflorestamento e no horto. Apenas 18,6% dos enxames coletados estavam expostos ao ar livre, estando preferencialmente em galhos, e 81,4% estavam alojados no interior de cavidades. Foi observado que, nos alojados em cavidades, as abelhas preferiram instalar seus enxames sob telhados (30%, ocos de árvores (20%, dentro de cavidades de cimento (12,9% e buracos no solo (10%. Observou-se que as abelhas não foram consideradas defensivas em 86,2% dos enxames coletados e que preferiram construir seus favos em posição perpendicular (70,4% à entrada da colméia, em relação à posição paralela (29,6%. Em relação à quantidade de indivíduos, cria e alimento, observou-se que 54,7% dos 70 enxames tinham grande quantidade de abelhas, 43,9% tinham área de cria considerada média e 51,7% apresentaram pouco alimento estocado.

    Full Text Available Recent introduction of hybrid varieties raises the question if bees (Apis mellifera L. contribute as pollinator agents in developing the full yield potential of rapeseed (Brassica napus L.. In order to evaluate the yield achieved by B. napus cv. Artus pollinated by A. mellifera testing was carried out in the district of Freire, La Araucanía Region, Chile. This consisted in isolating or excluding rapeseed plants from pollinators with exclusion cages. Treatments applied were total exclusion (T1, partial exclusion (T2 and free pollination (T0 with a density of 6.5 hives ha-1, in order to determine the following yield components traits: grains per silique, siliques per plant, 1000 grain weight and yield. The experimental design used was randomized complete blocks with three treatments and three replicates. Results obtained show that the parameter least affected by bee intervention was the grains per silique variable. In contrast, siliques per plant and 1000 grain weight parameters presented significant differences, contributing to a yield greater than 5 t ha-1; which represented a figure 50.34% higher than in the treatment without bees. It may be concluded that the inclusion of bees in crops is fully justified as a production tool.La reciente introducción de variedades híbridas plantea la interrogante de la contribución que pueda tener la presencia de abejas (Apis mellifera L. como agentes polinizadores para desarrollar en pleno el potencial productivo del raps (Brassica napus L..

    Full Text Available The Varroa destructor mite has caused the death of hundreds of thousands of Apis mellifera colonies in several countries worldwide. However, the effects determined by the Varroa mite change according to the A. mellifera subspecies. In Africanized bee colonies from South and Central America, the parasite causes little damage, as the infestation levels are relatively stable and low, thus treatments against the pest are not required. Among several factors, the grooming behavior of Africanized worker bees plays an important role in the maintenance of the low infestation levels. This study determined the daily rate of live and dead mites found at the bottom of the hive in five Africanized honey bee colonies. During fifteen days of observations, a significant increase was verified in the number of live and dead mites at the bottom of the hive as the amount of worker broods from each honey bee colony decreased. This suggests a more intense grooming activity as the Varroa concentration in the adult honey bee population increases.O ácaro Varroa destructor tem causado a mortalidade de centenas de milhares de colônias de abelhas Apis mellifera em várias partes do mundo. Os efeitos determinados pelo ácaro Varroa variam com a subespécie de Apis mellifera. Nas Américas do Sul e Central, o parasita causa poucos danos às colônias de abelhas africanizadas, a taxa de infestação é estável e baixa, não sendo necessário o tratamento químico contra a praga. Entre vários fatores que são responsáveis pela tolerância das abelhas africanizadas a esse parasita, o comportamento de grooming executado pelas operárias deve exercer importante papel na manutenção dos baixos níveis deinfestação. Neste estudo, foram avaliadas as taxas diárias de ácaros vivos e mortos encontrados no fundo das colméias de cinco colônias de abelhas africanizadas. Durante 15 dias de observações, foi verificado significativo aumento de ácaros no fundo da colméia

    Full Text Available El concepto de que el comportamiento de los animales esta determinado genéticamente no es nuevo si se considera que ya Darwin en su famosa obra El origen del hombre, en 1871 mencionaba que… “los rasgos del temperamento de los animales son heredados”. Pero solo hasta hace casi 50 años fue que la genética del comportamiento surgió como una especialidad importante dentro de la Genética; desde esa época muchos son los avances que refuerzan la idea generalmente aceptada de que todos los patrones comportamentales están determinados por componentes tanto ambientales como genotípicos. El análisis del control genético de un determinado comportamiento es complicado por el hecho de que las acciones primarias de un gene pueden afectar: 1. Los órganos sensoriales, cambiando la información recibida. 2. Sistemas intermedios (nervioso, endocrino, alterando capacidades de coordinación y percepción y 3. Órganos efectores, alterando la respuesta. Las mutaciones inducidas, que bloquean o alteran los patrones normales de comportamiento, proporcionan una herramienta muy útil para entender como los genes influencian la conducta (Hall et al, 1982. Al respecto hay muchos ejemplos, cuyo conocimiento ha servido para controlar o seleccionar caracteres indeseables o deseables (respectivamente, importantes para el mejoramiento en algunas especies animales. Por ejemplo, con la llegada de la abeja africanizada a América del Sur (Brasil,1958 (Kerr, 1967 llegaron también varios inconvenientes generados por el fuerte comportamiento defensivo de la nueva subespecie introducida (Apis mellifera scutellata , lo cual hizo que se iniciaran programas de investigación tendientes a conocer la biología y el comportamiento de la nueva especie introducida, de manera que se pudieran establecer cepas de abejas menos defensivas, conjuntamente con otras características como productividad o comportamiento higiénico.

    Full Text Available A apicultura brasileira usa da captura de enxames silvestres de abelhas melíferas africanizadas (Apis mellifera L. para repor e/ou aumentar o número de colônias dos apiários, possuindo inconvenientes como a dependência da natureza para captura dos enxames, a heterogeneidade genética das colônias capturadas e a possibilidade desses enxames serem portadores de doenças e parasitas prejudiciais à sanidade das abelhas. O presente trabalho testa e apresenta uma técnica de divisão de colônias de abelhas melíferas africanizadas para a produção de novas colônias fortes em curto espaço de tempo, a partir de recursos mínimos de cera, cria e alimento. Os resultados mostraram que núcleos de A. mellifera formados inicialmente com uma rainha jovem e fecundada, 1 kg de operárias, um quadro de cria fechada, um quadro de favo puxado e vazio e dois quadros com cera alveolada permitem a produção de novas colônias em 42 dias. Portanto, pode-se concluir que a técnica de divisão de colônias por formação de núcleos como descrito acima, oferece aos apicultores uma alternativa viável para a produção e comercialização em larga escala de novas colônias de abelhas melíferas africanizadas.The Brazilian apiculture relies upon collecting wild swarms of Africanized honey bees (Apis mellifera L. to replace and/or increase the number of colonies in the apiaries. This practice brings problems such as dependence on nature to capture any swarm, diverse genetic make-up of the colonies captured and the possibility of these swarms be carrying diseases and parasites harmful to the bees. The present work tests and presents a technique to split colonies of Africanized honey bees to produce new strong colonies in short time, departing from little resources of wax, brood and food stores. Results showed that A. mellifera nuclei formed by a young and mated queen, 1kg of workers, a frame of sealed brood, an empty frame of drawn beeswax and two frames

    Full Text Available La necesidad de diversificar cultivos ha marcado el comienzo de otras alternativas agronómicas en nuestro país tales como la producción de manzano. Hace unos 6 años se inició en Colombia la plantación de cultivares comerciales mejorados de cuya biología y necesidades poco se sabe. Se planteó un estudio sobre la influencia de la polinización entomófila en la producción de manzana Anna. El trabajo se desarrolló en un cultivo de manzano en el Municipio del Carmen de Viboral (Oriente Antioqueño, correspondiente a la zona de vida bosque húmedo montano bajo (bh-MB, con temperatura promedio anual de 14-24°C, altura de 2200 msnm y precipitación promedio anual de 1800 mm. Se propuso estimar el efecto de los insectos polinizadores en la producción, comparando ésta en ramas enjauladas excluidas de todos los visitantes florales, con la de ramas expuestas a éstos durante la floración, en árboles escogidos al azar. Se encontró que las ramas que habían sido visitadas por insectos producían significativamente más manzanas (t = 2,95, para t0.05 con 18 g.l., con mayor pesos (t=2,21, para t0.05 con 18 g.l. y mayor número de semillas (t=3.75, para t0.05 con 18 g.l., que ramas sin acceso de visitantes florales. Una medición de índices de diversidad mostró que la abeja melífera (Apis mellifera L. constituyó el 76% de los visitantes florales y que la diversidad fue muy baja (λ=0.7439. Se concluyó que el manzano Anna requiere polinización entomófila, que la abeja melífera fue el polinizador más importante y que se incrementó significativamente la producción de frutos bajo la influencia de esta especie de abeja. Se recomienda la introducción al cultivo de Apis mellifera al momento de la floración, para garantizar una producción adecuada.

However, the effects determined by the Varroa mite change according to the A. mellifera subspecies. In Africanized bee colonies from South and Central America, the parasite causes little damage, as the infestation levels are relatively stable and low, thus treatments against the pest are not required. Among several factors, the grooming behavior of Africanized worker bees plays an important role in the maintenance of the low infestation levels. This study determined the daily rate of live and dead mites found at the bottom of the hive in five Africanized honey bee colonies. During fifteen days of observations, a significant increase was verified in the number of live and dead

    Full Text Available A técnica de criação de larvas de abelhas Apis mellifera em laboratório tem sido utilizada freqüentemente em estudos de desenvolvimento larval, determinação de castas e, mais recentemente, em testes de patogênese. A quantidade e a qualidade do alimento fornecido às larvas em laboratório podem levar à formação de castas diferentes (rainha, operárias ou intercastas. Neste trabalho, crias de abelhas africanizadas foram desenvolvidas a partir de larvas de 18-24 horas de idade até atingir a fase adulta, utilizando-se durante a alimentação, 4, 15, 25, 50 e 70 µl de dieta por larva, respectivamente, do primeiro ao quinto dia de alimentação. Para determinar se as abelhas adultas obtidas em laboratório eram pertencentes à casta de operárias, de rainhas ou se eram intermediárias (intercastas, foram comparadas com um controle constituído por operárias e rainhas da mesma origem das operárias desenvolvidas no laboratório, utilizando-se o peso e as medidas dos seguintes caracteres: a comprimento da cabeça; b largura da cabeça; c comprimento do olho composto; d largura do olho composto; e comprimento do mesoscuto; f largura do mesoscuto; g comprimento da tíbia; h largura da tíbia. Foram utilizadas a Função Discriminante de Anderson e a técnica de Componentes Principais, de modo a efetuar a discriminação das castas das abelhas adultas obtidas em laboratório em relação àquelas desenvolvidas naturalmente. Entre os caracteres avaliados, os que menos contribuíram para a determinação das castas foram o comprimento do mesoscuto e a largura da cabeça, sendo, portanto, dispensáveis em estudos futuros.Apis mellifera honeybee brood rearing in laboratory conditions has been frequentely used to search for larval development, caste determination, and more recently for tests of pathogenesis. The amount and quality of food received by larvae during the feeding time can produce different castes (queen, worker or intercaste. In the

    Los polinizadores altamente especializados en su dieta, no hacen escogencias florales, ellos visitan un recurso específico siguiendo el dictado de la información almacenada en sus genes. En contraste, para la abeja social Apis mellifera una escogencia floral implica, la toma de una decisión, usualmente con criterio económico, basada en información aprendida y almacenada en alguna forma de memoria. Aunque existen numerosos estudios y modelos sobre la escogencia floral en abejas, la gran mayoría de éstos, han derivado sus conclusiones a partir de condiciones temporalmente fijas de la interacción. Muy pocos estudios han abordado la dinámica propia del contexto ecológico, en el cual el mercado floral de las abejas cambia con las estaciones del año y con los patrones diarios de antesis floral. Este cambio en la disponibilidad de especies florales enfrenta a los polinizadores, a realizar escogencias secuenciales acerca del alimento a explotar. En este trabajo abordo el tema del forrajeo secuencial en parches florales heterospecíficos, enfocándome en el uso que la abeja melífera hace de la información previamente aprendida en un contexto, cuando se enfrenta a la explotación de alimento en un contexto ecológicamente diferente. He realizado experimentos sobre escogencia floral simulando las condiciones de cambio del paisaje floral, exponiendo abejas individuales de A. mellifera a decidir sobre cuales especies forrajear en cada parche. Los resultados indican que la abeja invierte en procesos de aprendizaje en un muestreo inicial, pero una vez almacenada la información, utiliza una pieza de la información previamente aprendida (color para explotar parches florales heteroespecíficos siguiendo una imagen de búsqueda de color.

    Full Text Available Beekeeping is an activity that produces significant benefits to agriculture and the environment; Through the pollination action of bees helps to increase productivity as well as biodiversity in the ecosystem. In recent years, has significantly increased prevalence of parasites in this species, particularly the Varroasis, a disease caused by the mite Varroa destructor. The causal agent produces losses between 30% and 50% of total production and in turn can cause damage to the quality of honey by the excessive use of chemicals for disease control and the slow and progressive deterioration health of producers. Noting this, we evaluated the incidence of fungus Beauveria bassiana in natural populations of Varroa destructor in acarofauna associated, and the remains of the hive by pathogenicity tests in laboratory conditions to evaluate the effect of the biocontrol entomopathogenic then enter in apiaries infected with the disease. According to the results obtained in the adult infestation of V. destructor in Apis mellifera Africanized sampling Felisa made on the farm in the municipality of Los Patios, recorded rates of infestation in hives from 3.4% to 8.3% on the infection status of breeding was 4.5% to 13.7%. In laboratory tests it was possible to observe thatthe fungus B. bassiana attacked by an effective control mites without harming bees, propolis and honey allowing the insect to continue their normal activities, controlling the disease in a biological, not chemical.

El trabajo se llevó a cabo en Coronel Vidal, provincia de Buenos Aires. Se trabajó sobre colmenas tipo Langstroth del híbrido regional de Apis mellifera (Linneaus. En cada colmena experimental se procedió a confinar a la reina en panales trampa específicos, con el fin de poder controlar la oviposición. Estos panales, luego de ser operculados por las obreras, fueron llevados al laboratorio donde se desoperculó cada una de las celdas de cría, y se contabilizó el número de ácaros presentes. Esta técnica se aplicó variando el número de panales trampa (1-3 colocados, tanto para los constituidos por celdas de cría de obreras como de zánganos. También, se evaluó el impacto de la aplicación de esta técnica sobre el desarrollo de las colonias, mediante la medición de su productividad. Los resultados indican, que la técnica empleada sólo es efectiva, cuando se aplican tres panales de cría de zánganos de manera consecutiva, alcanzando una efectividad máxima de 84%. Cuando se aplican tres panales de obreras, la técnica mostró niveles de efectividad muy inferiores (14%. En las colonias sobre las que se aplicó esta técnica, la productividad de miel se redujo significativamente, comparada con las colonias control. Esta técnica resulta ideal para ser combinada con otros mecanismos de control, disminuyendo la aplicación de sustancias químicas que puedan contaminar la miel, y la generación de resistencia por parte del ácaro frente a los principios activos utilizados para su control.At present, Varroosis is considered the major problem to beekeeping development.

    GUIOMAR NATES-PARRA

    Full Text Available La abeja de miel (género Apis, Familia Apidae es uno de los organismos utilizados en estudios de comportamiento, debido a su forma de vida social, la cual requiere de coordinación entre todos los individuos de la comunidad. La división de trabajo dentro de una colonia de abejas es consecuencia de cambios fisiológicos relacionados con la edad de las obreras y con la variación genética entre ellas que hace que realicen diferentes tareas. Con los progresos en biología molecular, genómica y secuenciación del genoma de Apis mellifera, han surgido nuevas herramientas que permiten desentrañar las bases moleculares del comportamiento, en particular el comportamiento social. Numerosos estudios han mostrado que muchas de las conductas realizadas por las obreras están determinadas genéticamente (comportamiento defensivo, comportamiento higiénico y además que hay variación genética entre poblaciones en el desempeño de tareas como recolección de agua, néctar y polen. Igualmente algunos aspectos del comportamiento social, como el control de la reproducción en las castas estériles, también están bajo influjo genético. En este trabajo se hace una revisión de las metodologías utilizadas para estudiar la genética del comportamiento, así como la base genética de algunas de las conductas más sobresalientes de abejas.The honeybee Apis mellifera (Apidae is a model widely used in behavior because of its elaborate social life requiring coordinate actions among the members of the society. Within a colony, division of labor, the performance of tasks by different individuals, follows genetically determined physiological changes that go along with aging. Modern advances in tools of molecular biology and genomics, as well as the sequentiation of A. mellifera genome, have enabled a better understanding of honeybee behaviour, in particular social behaviour. Numerous studies show that aspects of worker behaviour are genetically determined

Los productos NeoNim 60 y OleoNim 80, obtenidos del árbol del Nim, están propuestos para su uso como insecticida, nematicida y acaricida. Con el objetivo de realizar la evaluación ecotoxicológica de estos productos, se realizaron los ensayos de toxicidad aguda en lombriz de tierra Eisenia andrei y de toxicidad aguda por contacto en abejas Apis mellifera. Cada ensayo contó con un grupo control y dos tratados. El ensayo en lombrices se realizó durante 14 días utilizando suelo artificial, realizando observaciones clínicas, conteo de animales y estudio del comportamiento de la biomasa. La prueba en abejas se prolongó por 48 horas, realizándose observaciones clínicas y conteo de animales. Se obtuvo un 100% de supervivencia en las lombrices de los grupos tratados, obteniendo en el NeoNim 60 valores de disminución de la biomasa significativamente inferiores al grupo control, mientras que el grupo tratado con OleoNim 80 mostró aumento en la biomasa del inicio al final del ensayo. En el ensayo en abejas, la comparación estadística no mostró diferencias entre grupos en cuanto a la mortalidad. Teniendo en cuenta el conjunto de los resultados obtenidos, se pudo concluir que los derivados del Nim NeoNim 60 y OleoNim 80 no producen efecto tóxico sobre las lombrices de tierra y las abejas.

    Full Text Available Las abejas silvestres de Colombia, al igual que las del resto del mundo, están sufriendo los rigores de las actividades desarrolladas por el hombre y así se catalogan como organismos en peligro. El conocimiento actual de las abejas en nuestro país, como muchos otros insectos, todavía se encuentra en una fase muy incipiente; es fragmentado, local y carece de una síntesis. Tan sólo se conoce racionalmente 5% de las abejas del país, especialmente las especies corbiculadas de la familia Apidae. Muy poco trabajo taxonómico ha sido realizado por investigadores colombianos y prácticamente no existen trabajos por autores extranjeros enfocados en la fauna colombiana. La carencia de especialistas, las dificultades para el envío de material al exterior y la falta de recursos han dificultado la tarea. Sin embargo, la alta riqueza de especies que creemos se encuentra en el país representa una razón más para avanzaren el conocimiento y entendimiento de la biodiversidad de éste grupo. En esta revisión se analizan las principales causas que ponen en riesgo las poblaciones y especies de la apifauna nativa: deforestación, pastoreo, la abeja africanizada y la explotación irracional de las abejas, entre otras. Se proponen algunas acciones a ser emprendidas conjuntamente con centros académicos, agricultores, campesinos, indígenas y la sociedad en general que permitan proteger las especies, teniendo en cuenta que median-te la polinización, se tornan en eslabones esenciales dentro de los ecosistemas permitiendo la conservación de muchas especies vegetales y otras comunidades.The Colombian wild bees, as well as those in the rest of the whole world are undergoing the rigor of human activities and so are considered to be under threat of extinction.

    Full Text Available This work studies the acute contact toxicity of oxalic acid (OA on a honeybee polyhybrid subspecies (Apis mellifera, which is the dominant biotype in southwestern zone of Uruguay (SWZU and the country's most important honey-producing region. We determined the mean lethal dose (LD50, as well as the no observed effect level (NOEL and the lowest observed effect level (LOEL values. We also estimated the total number of honeybees per hive in the test area. The aim was to assess the relationship between the maximum OA dose used in Uruguay (3.1 g OA per hive and the toxicological parameters of honeybees from SWZU. The current dose of 3.1 g OA per hive corresponds to 132.8 OA per honeybee since determined NOEL is 400 OA per honeybee; our results indicate that the current dose could be increased to 9.3 g OA per hive. The results also highlight some differences between the LD50 value in SWZU honeybees (548.95 OA per honeybee and some published LD50 values for other honeybee subspecies.Este trabajo estudió la toxicidad aguda por contacto del ácido oxálico (AO sobre una subespecie poli-híbrida de abejas (Apis mellifera, la cual es el biotipo dominante en la zona sudoeste de Uruguay (SWZU, la región más importante para la producción de miel en este país. Este estudio determinó la dosis letal 50 (DL50, así como el nivel de efecto no observado (NOEL, el nivel de efecto mínimo observado (LOEL, y el número total de individuos por colmena. El propósito fue evaluar la relación entre la dosis máxima de AO usada en Uruguay (3.1 g AO por colmena y los parámetros toxicológicos de las abejas de la SWZU.

    Full Text Available Debido a su rol como polinizador y productor de miel, la abeja Apis mellifera L. es considerado un insecto beneficioso. Si bien Argentina juega un papel de liderazgo en la producción de miel, existe un considerable vacío en el conocimiento acerca de las enfermedades de etiología protista que afectan las abejas en el país. La ameba Malpighamoeba mellificae Prell es un protista entomopatógeno que invade los túbulos de Malpighi de las abejas e interfiere con el proceso de excreción, debilitando al huésped y posiblemente facilitando la acción de otros patógenos.

    Full Text Available Entre los factores que pueden ayudar a disminuir y controlar la población de Varroa destructor en colonias de Apis mellifera está el comportamiento de acicalamiento. Este comportamiento consiste en la capacidad de la abeja de detectar, morder y eliminar los parásitos en etapa forética. En esta investigación se analizó la presencia del comportamiento de acicalamiento en colonias de abejas a través de la observación de ácaros dañados. Para ello se utilizaron seis colonias de abejas de la especie A. mellifera en colmenas tipo Langstroth, las cuales se evaluaron diariamente durante 30 días en abril y mayo del año 2008. Las muestras correspondieron a la caída diaria de ácaros a placas de metal con vaselina, ubicada en el piso de cada colmena por un periodo de 24 horas. Los resultados indicaron 95% de varroas caídas muertas y 5% vivas de un total de 2.005 varroas. Se encontró un 49% de ácaros con daños y 51% sin daños. Con base en lo observado existe la posibilidad de elegir colonias con comportamiento de acicalamiento de importancia como daño dorsal y daño completo sobre el acaro, lo cual puede ser muy útil para estudiar selección de abejas y diseñar estrategias de manejo integrado del ácaro V. destructor.Among the factors that can help to diminish and control populations of Varroa destructor in colonies of Apis mellifera is grooming behaviour. This behaviour consists of the capacity of the bee to detect, bite and eliminate parasites in the phoretic stage. In this investigation we evaluated the presence of grooming behavior in bee colonies through observations of damaged mites. For this we used six colonies of A. mellifera in Langstroth type beehives, which were evaluated daily for 30 days in April and May of 2008. The samples consisted of daily mite fall onto metal sheets coated with vaseline, placed in the floor of each beehive for a period of 24 hours. The results showed 95% of fallen mites dead and 5% alive out of a total

  14. Varroa jacobsoni infestation of adult Africanized and Italian honey bees (Apis mellifera in mixed colonies in Brazil

    Geraldo Moretto

    1999-09-01

    Full Text Available Different levels of infestation with the mite Varroa jacobsoni have been observed in the various Apis mellifera races. In general, bees of European races are more susceptible to the mite than African honey bees and their hybrids. In Brazil honey bee colonies are not treated against the mite, though apparently both climate and bee race influence the mite infestation. Six mixed colonies were made with Italian and Africanized honey bees. The percentage infestation by this parasite was found to be significantly lower in adult Africanized (1.69 ± 0.44 than Italian bees (2.79 ± 0.65. This ratio was similar to that found in Mexico, even though the Africanized bees tested there had not been in contact with varroa, compared to more than 20 years of the coexistence in Brazil. However, mean mite infestation in Brazil on both kinds of bees was only about a third of that found in Mexico.Desde o contato inicial entre o ácaro Varroa jacobsoni e a abelha Apis mellifera, diferentes níveis de infestação foram verificados entre as diversas raças dessa espécie de abelhas. O presente trabalho teve como objetivo verificar o grau de infestação determinado pelo acaro Varroa jacobsoni em abelhas Apis mellifera, africanizadas e italianas puras, quando criadas numa mesma colméia. Para isso, o grau de infestação foi obtido em seis colônias de abelhas constituídas de operárias de ambas as raças. O resultado de dezesseis repetições mostrou que as abelhas africanizadas foram menos infestadas que as abelhas italianas. Esse resultado sugere que, nas condições naturais de infestação, as abelhas africanizadas são mais defensivas ao parasita Varroa jacobsoni, garantindo a essa raça de abelhas a resistência à praga varroosis.

    Full Text Available En cuatro localidades de la zona de influencia del embalse Porce II (Antioquia, Colombia, se observó el comportamiento de 23 taxones de abejas durante sus visitas a Aspilia tenella (Kunth S. F. Blake; se registró el número de individuos y el tiempo total de visita y se midieron la temperatura y la humedad relativa. Los análisis de varianza indican que hubo una relación estadísticamente significativa en cuanto a los atributos considerados para las especies de abejas y una covariación significativa con las variables ambientales. Las pruebas de rangos múltiples muestran que Trigona nigerrima es la especie con los mayores valores promedio para el número de individuos y el tiempo de visita. En el estudio de las cargas polínicas se encontraron 30 tipos polínicos, dentro de los cuales A. tenella presentó el mayor porcentaje; Piper aduncum, Miconia minuti flora, Psidium guajava, Rapanea sp., Mimosa pudica y Psychotria sp., en su orden, son otras fuentes de polen importantes para varias de las especies de abejas. El análisis de agrupamiento para las abejas capturadas permitió diferenciar dos grupos: el primero incluye a 18 especies cuyas cargas polínicas que poseían una abundancia relativa de granos de polen de A. tenella por encima de 77%; el segundo grupo estaba conformado por cinco especies de abejas que recolectaron porcentajes mayores de otros tipos polínicos: Exomalopsis sp. 1 (90,4% de M. minuti flora; Lasioglossum sp. 1 y Coelioxys aff. mexicana (77,4% y 64,1% de P. aduncum, respectivamente; Exomalopsis sp. 2 (67,1% de P. guajava y Auglochloropsis vesta (55,5% de Rapanea sp.. Trigona fulviventris y Apis mellifera presentaron los valores más altos de riqueza de tipos polínicos en las cargas de polen; ello evidencia sus nichos tróficos amplios y su comportamiento generalista de visita.We observed the behavior of 23 species of wild bees visiting Aspilia tenella (Kunth S .F.

A pesar de que su cría y manejo (meliponicultura, es una actividad que viene creciendo y tecnificándose en Latinoamérica y otras regiones del mundo, sus características y desarrollo en Colombia han sido poco documentados. Se presentan los resultados de entrevistas y visitas a 75 personas en 16 departamentos de Colombia, que cultivan 25 especies de abejas sin aguijón, agrupadas en 12 géneros. Se encontraron al menos nueve especies más sin identificación completa, se reportan cuatro nuevos registros para el país y se amplía la distribución para 21 taxones. Se presenta información sobre la distribución regional y altitudinal, el cultivo urbano y las denominaciones locales para las abejas. Se revisan algunas características de los géneros cultivados más comunes (Tetragonisca, Melipona, Paratrigona, Scaptotrigona, y Nannotrigona y se discute la importancia del vínculo entre diversidad biológica y cultural que se manifiesta en los nombres locales reportados. Ante un escenario mundial de expansión de la meliponicultura, se resaltan necesidades de investigación y riesgos para la conservación y manejo de la diversidad de abejas sin aguijón y los conocimientos asociados.

Las crías operculadas de estas colonias fueron sacrifi cadas al puncionarlas con un alfi ler entomológico (P, y congelarlas en congelador a –18ºC (CC con nitrógeno líquido a –195º C (CN2. Se determinó el porcentaje de crías removidas por las abejas 24 h después de que fueron sacrifi cadas. Como consecuencia de la poca discriminación entre colonias inicialmente encontrada con la prueba P, se realizó un experimento adicional con 50 colonias, reduciendo el tiempo de lectura a 8 h y se verifi có el efecto producido por la emanación de olores y fl uidos de las crías sacrifi cadas. Las colonias fueron signifi cativamente más higiénicas (P 0.54, P 0.37, P < 0.01. La variación entre colonias fue mayor con las pruebas CN2 y CC que con la P. La prueba P fue la más económica y práctica de aplicar (6.59 pesos, 0.58 dólares, por colonia, pero mostró menor capacidad discriminatoria, que no se incrementó aun cuando se redujo el tiempo de lectura. Este resultado pudo deberse al fuerte estímulo provocado por olores y hemolinfa emanados de las crías sacrifi cadas. Las pruebas CN2 y CC mostraron alta capacidad discriminatoria, pero la primera fue más cara (14.80 pesos, 1.31 dólares y la menos práctica. La prueba CC fue la segunda más económica (10.15 pesos, 0.90 dólares y práctica.

    Full Text Available La nosemosis es una enfermedad que afecta las funciones digestivas de las abejas melíferas causada por los microsporidios Nosema apis y Nosema ceranae. En Uruguay la única especie detectada es N. ceranae. Para determinar si la incidencia de N. ceranae en las colonias tiene un componente genético se realizó una selección bidireccional para aumento de la resistencia y la susceptibilidad a este parásito sin control de la paternidad. Las colonias fueron evaluadas en una forestación de Eucalyptus grandis en otoño. La infección de las colonias se determinó como 1 el porcentaje de abejas pecoreadoras infectadas y 2 el número promedio de esporas por campo en 10 campos. El trabajo se inició con 138 colonias y se evaluaron dos generaciones de 30 y 63 colonias. La respuesta a la selección fue muy limitada, solo en la primera generación las colonias de la línea resistente presentaron menos esporas por abejas que las colonias de la línea susceptible (19,6 ± 5,8 y 26,8 ± 10,4, respectivamente, W = 41,5; P = 0.03. Esto indicaría que la resistencia a la nosemosis está fuertemente afectada por el ambiente. Futuros esfuerzos para aumentar la resistencia de las abejas a N. ceranae a través de mejora genética deberán incluir el control de la paternidad.

    RESUMEN

    Se estudiaron las cargas polínicas de 13 taxones de abejas capturadas visitando a Mimosa pigra en la zona de influencia del Embalse Porce II (Antioquia, Colombia. De los 21 tipos polínicos encontrados, M. pigra presenta el mayor porcentaje acumulado de colecta; Mimosa pudica, Piper aduncum, Solanum diversifolium, Warszewiczia coccinea y Psidium guajava, en su orden, se pueden considerar fuentes alternativas de polen, para varias de las especies de abejas cuyas cargas polínicas fueron analizadas. Dentro de las especies de abejas capturadas visitando a M. pigra se pueden diferenciar varios grupos según el tipo y abundancia relativa de los tipos polínicos encontrados en sus cargas. Uno de ellos, incluye a siete especies de abejas con más del 85% de granos de polen de M. pigra; otro, con cuatro especies de abejas que colectaron más del 94,5% del polen en M. pigra y M. pudica. Adicionalmente, se encontraron especies como Trigona dorsalis con cargas de M. pigra (59,4%, de S. diversifolium (37,8% y especies de abejas como Lasioglossum sp. 113, en cuyas cargas polínicas predominan los granos de polen de P. aduncum (61,8% y de W.coccinea (36,4%, en contraste con los de M. pigra (1,3%. En cuanto a la riqueza de tipos polínicos colectados por las abejas sobresalen Trigona muzoensis (12 tipos polínicos y T. dorsalis (10 tipos, lo cual refleja nichos tróficos más amplios para estas especies y deja duda sobre su constancia floral o hábitos de limpieza.

Users interact with DIRAC via command line, using the web portal or accessing resources via the DIRAC python API. The current DIRAC API requires users to use a python version valid for DIRAC. Some communities have developed their own software solutions for handling their specific workload, and would like to use DIRAC as their back-end to access distributed computing resources easily. Many of these solutions are not coded in python or depend on a specific python version. To solve this gap DIRAC provides a new language agnostic API that any software solution can use. This new API has been designed following the RESTful principles. Any language with libraries to issue standard HTTP queries may use it. GSI proxies can still be used to authenticate against the API services. However GSI proxies are not a widely adopted standard. The new DIRAC API also allows clients to use OAuth for delegating the user credentials to a third party solution. These delegated credentials allow the third party software to query to DIRAC on behalf of the users. This new API will further expand the possibilities communities have to integrate DIRAC into their distributed computing models.

    2010-09-01

    Full Text Available In recent years, there has been an explosive growth in the popularity of online social networks such as Facebook. In a new twist, third party developers are now able to create their own web applications which plug into Facebook and work with Facebook's "social" data, enabling the entire Facebook user base of more than 400 million active users to use such applications. These client applications can contain subtle errors that can be hard to debug if they misuse the Facebook API. In this paper we present an experience report on applying Microsoft's new code contract system for the .NET framework to the Facebook API.We wrote contracts for several classes in the Facebook API wrapper which allows Microsoft .NET developers to implement Facebook applications. We evaluated the usefulness of these contracts during implementation of a new Facebook application. Our experience indicates that having code contracts provides a better and quicker software development experience.

  6. The API petroassist network

    Past spill responses, such as those in the Exxon Valdez and American Trader incidents, demonstrated the value of companies volunteering their in-house experts and local knowledge to help other companies in spill response. The American Petroleum Institute (API) formed the PetroAssist Network to provide a means for oil companies to readily gain access to the expertise and communications equipment of other oil companies when needed for spill responses. An API work group developed the PetroAssist Network legal agreement and management and activation procedures. To minimize red tape and reduce the burden on members, existing systems were used whenever possible. The network became operational on January 1, 1992, with more than 40 members

  7. Associated particle imaging (API)

    NONE

    1998-05-01

    Associated Particle Imaging (API) is an active neutron probe technique that provides a 3-D image with elemental composition of the material under interrogation, and so occupies a unique niche in the interrogation of unknown objects. The highly penetrating nature of neutrons enables API to provide detailed information about targets of interest that are hidden from view. Due to the isotropic nature of the induced reactions, radiation detectors can be set on the same side of the object as the neutron source, so that the object can be interrogated from a single side. At the heat of the system is a small generator that produces a continuous, monoenergetic flux of neutrons. By measuring the trajectory of coincident alpha particles that are produced as part of the process, the trajectory of the neutron can be inferred. Interactions between a neutron and the material in its path often produce a gamma ray whose energy is characteristic of that material. When the gamma ray is detected, its energy is measured and combined with the trajectory information to produce a 3-D image of the composition of the object being interrogated. During the course of API development, a number of improvements have been made. A new, more rugged sealed Tube Neutron Generator (STNG) has been designed and fabricated that is less susceptible to radiation damage and better able to withstand the rigors of fielding than earlier designs. A specialized high-voltage power supply for the STNG has also been designed and built. A complete package of software has been written for the tasks of system calibration, diagnostics and data acquisition and analysis. A portable system has been built and field tested, proving that API can be taken out of the lab and into real-world situations, and that its performance in the field is equal to that in the lab.

    Full Text Available Las abejas de las orquídeas, propias de la región neotropical, parecen haber aparecido recientemente entre el piedemonte de la cordillera de los Andes y la Amazonía. Además éstas abejas de lengua larga y vuelos amplios
    llaman la atención por sus características biológicas, fisiológicas, ecológicas y comportamentales que comparadas con el resto de las tribus más cercanas a ellas (las abejas corbiculadas: Meliponini, Bombini y Apini
    presentan diferencias importantes. Debido a esto y a que son importantes polinizadores, es de especial interés
    establecer sus patrones de distribución, particularmente en Colombia, debido a las características geográficas
    del país. Con base en el material de euglosinos depositados en la colección del LABUN, referencias bibliográficas, características morfológicas y comporamentales de la tribu, así como la localización geográfica y altitudinal de las especies, se desarrolló un análisis de correspondencia para determinar cómo las diferentes variables podrían estar implicadas en la distribución de los euglosinos en Colombia. Los resultados del análisis multivariado muestran que no hay una estrecha relación de las especies de euglosinos a las regiones naturales que ocupan, sino que dentro de las variables consideradas, el tamaño corporal (implicado en capacidad de vuelo y la termorregulación, la estructura social (asociada a aprovechamiento y optimización de recursos en el hábitat y la longitud de la lengua (relacionada con la preferencia y toma de néctares, generan la mayor variabilidad de la muestra. De acuerdo a las características morfológicas y comportamentales analizadas se propone un patrón biogeográfico para la distribución de las abejas euglosinas en Colombia.

    2006-03-01

    Full Text Available JUSTIFICATIVA E OBJETIVOS: As abelhas empregadas inicialmente na produção melífera eram de origem européia, sendo de baixa produtividade e mansas. Em 1956 foram trazidas espécies africanas com maior capacidade produtiva, porém extremamente agressivas. Houve soltura acidental destas abelhas na natureza e ocorreu cruzamento entre as espécies, gerando linhagem de abelhas africanizadas. O objetivo deste relato é sugerir uma padronização de atendimento a pacientes vítimas da síndrome de envenenamento dado o número crescente de casos de ataques maciços por estas abelhas e a literatura escassa sobre o assunto. RELATO DO CASO: Paciente do sexo masculino, 19 anos, que durante treinamento militar foi atacado por enxame de abelhas africanizadas. CONCLUSÕES: As abelhas africanizadas por serem muito agressivas, atacam suas vítimas com elevado numero de picadas inoculando grande quantidade de veneno. As reações às picadas podem variar desde reação inflamatória local em indivíduos não sensibilizados, reação de hipersensibilidade e choque anafilático em indivíduos sensibilizados ou síndrome de envenenamento, quando devido a grande quantidade de veneno inoculado, os efeitos tóxicos se sobrepõem à reação anafilática. O atendimento a este tipo de acidente deve ser o mais precoce possível, com a realização de suporte clínico adequado e remoção mecânica dos ferrões. A estabilização hemodinâmica é de suma importância.BACKGROUND AND OBJECTIVES: Honeybees first used in the honey production came from Europe. They were gentle but their productivity was very low. In 1956 it was brought from Africa some species of honeybees that were more productible but also extremely aggressive. There was an accidental release of those bees, that proliferated by hybridizing with the European honeybees generating a new specimen of bees: the Africanized honeybees. The objective of this article is to suggest a pattern of treatment for this

En los análisis realizados se utilizó GC-MS previa extracción con solventes orgánicos. Debido a dificultades iniciales en la identificación de plaguicidas sobre tres de las muestras, se procedió al reprocesamiento de los cromatogramas utilizando selección de las relaciones de masas m/z 158, 173 y 143. Utilizando es herramienta analítica se obtuvieron los correspondientes cromatogramas, y los espectros de masas con coincidencia frente al divulgado para el producto de descomposición de bromadiolona (PDB, determinando que tanto las abejas como las colmenas habían tenido contacto con bromadiolona (3-[3-(4'-bromobifenil-4-il- 3-hidroxi-1-fenilpropil]-4- hidroxicumarina, un anticoagulante cumarínico de utilización agraria para combatir roedores, que parece ser prácticamente no tóxico para las abejas según informes internacionales. Se observó que en la literatura no se halla propuesta una estructura química definida para el PDB, lo cual podría constituir el fundamento para encarar trabajos futuros con el fin de elucidar el comportamiento de la droga madre en el contexto del caso.As a result of an investigation boosted by ordinary justice, samples from a probable deliberate spill of pesticide over bees and hives were analyzed.

    In this lesson, you’ll learn how to use python with the Zotero API to interact with your Zotero library. The Zotero API is a powerful interface that would allow you to build a complete Zotero client from scratch if you so desired. But like most APIs, it works in small, discrete steps, so we have to build our way up to the complicated requests we might want to use to access our Zotero libraries. But this incremental building gives us plenty of time to learn as we go along.

    CLARA ISABEL AGUILAR SIERRA

    Full Text Available Se estudiaron las cargas polínicas de 13 taxones de abejas capturadas visitando a Mimosa pigra en la zona de influencia del Embalse Porce II (Antioquia, Colombia. De los 21 tipos polínicos encontrados, M. pigra presenta el mayor porcentaje acumulado de colecta; Mimosa pudica, Piper aduncum, Solanum diversifolium, Warszewiczia coccinea y Psidium guajava, en su orden, se pueden considerar fuentes alternativas de polen, para varias de las especies de abejas cuyas cargas polínicas fueron analizadas. Dentro de las especies de abejas capturadas visitando a M. pigra se pueden diferenciar varios grupos según el tipo y abundancia relativa de los tipos polínicos encontrados en sus cargas. Uno de ellos, incluye a siete especies de abejas con más del 85% de granos de polen de M. pigra; otro, con cuatro especies de abejas que colectaron más del 94,5% del polen en M. pigra y M. pudica. Adicionalmente, se encontraron especies como Trigona dorsalis con cargas de M. pigra (59,4%, de S. diversifolium (37,8% y especies de abejas como Lasioglossum sp. 113, en cuyas cargas polínicas predominan los granos de polen de P. aduncum (61,8% y de W.coccinea (36,4%, en contraste con los de M. pigra (1,3%. En cuanto a la riqueza de tipos polínicos colectados por las abejas sobresalen Trigona muzoensis (12 tipos polínicos y T. dorsalis (10 tipos, lo cual refleja nichos tróficos más amplios para estas especies y deja duda sobre su constancia floral o hábitos de limpieza.We studied the pollen loads of 13 taxa of wild bees visiting the flowers of Mimosa pigra on the influence zone of the Dam Project Porce II (Antioquia, Colombia.

    2001-01-01

    As programmers we have worked with many Application Development Interface API development kits. They are well suited for interaction with a particular system. A vast source of information can be made accessible by using the http protocol through the web as an API. This setup has many advantages including the vast knowledge available on setting web servers and services. Also, these tools are available on most hardware and operating system combinations. In this paper I will cover the various types of systems that can be developed this way, their advantages and some drawbacks of this approach.

  13. ECOLOGICAL IMPACT ON NATIVE BEES BY THE INVASIVE AFRICANIZED HONEY BEE

    ROUBIK DAVID

    2009-08-01

    Full Text Available ABSTRACT

    Very little effort has been made to investigate bee population dynamics among intact wilderness areas. The presence of newly-arrived feral Africanized honey bee (AHB, Apis mellifera (Apidae, populations was studied for 10-17 years in areas previously with few or no escaped European apiary honey bees. Here I describe and interpret the major results from studies in three neotropical forests: French Guiana, Panama and Yucatan, Mexico (5° to 19° N. latitude. The exotic Africanized honey bees did not produce a negative effect on native bees, including species that were solitary or highly eusocial. Major differences over time were found in honey bee abundance on flowers near habitat experiencing the greatest degree of disturbance, compared to deep forest areas. At the population level, sampled at nest blocks, or at flower patches, or at light traps, there was no sudden decline in bees after AHB arrival, and relatively steady or sinusoidal population dynamics. However, the native bees shifted their foraging time or floral species. A principal conclusion is that such competition is silent, in floristically rich habitats, because bees compensate behaviorally for competition. Other factors limit their populations.

    Key words: Africanized honey bee, native bees, competition, population dynamics, neotropical forests

    RESUMEN Pocos estudios han considerado la dinámica de poblaciones de abejas en bosques o hábitats no alterados por el hombre.

    Full Text Available Cassava producers in the region of Marília-São Paulo are integrating their farming activity with beekeeping to diversify their income. The aim of this study was to evaluate the physicochemical and microbiological quality of honey samples produced by Africanized honeybees Apis mellifera from cassava flower in 2008. Analysis were carried out for pH, total soluble solids (TSS, acidity, moisture, reducing and total sugars, apparent sucrose, hydroxymethylfurfural, color, ash, proteins, water insoluble solids, diastasic activity, mineral content, microbiological evaluations, and mineral and hydrocyanic acid (HCN content. The honey samples showed physicochemical and microbiological characteristics favorable to commercialization, with the exception of apparent sucrose and acidity, which show the need for a narrow focus of attention to the honey maturation degree at the harvest time and more careful monitoring during production and processing. The commercialization of Brazilian cassava honey, still little explored, can be widely spread in the market since the levels of hydrocyanic acid (HCN showed no consumption risk; in addition the simultaneous production of honey and cassava provides an alternative to family income increase.Produtores de mandioca da região de Marília, Estado de São Paulo, estão consorciando a atividade da apicultura em meio à cultura visando diversificar a renda obtida pela propriedade rural. Este trabalho teve como objetivo avaliar a qualidade físico-química e microbiológica do mel produzido por abelhas Apis mellifera africanizadas, elaborado a partir de flores de mandioca, no ano de 2008. Foram realizadas análises de pH, sólidos solúveis totais (SST, acidez, umidade, açúcares redutores e totais, sacarose aparente, hidroximetilfurfural, cor, cinzas, proteínas, sólidos insolúveis em água, atividade diastásica, teor de minerais e monitoramento dos teores de ácido cianídrico (HCN, além de avaliações microbiol

  4. API Requirements for Dynamic Graph Prediction

    Gallagher, B; Eliassi-Rad, T

    2006-10-13

    Given a large-scale time-evolving multi-modal and multi-relational complex network (a.k.a., a large-scale dynamic semantic graph), we want to implement algorithms that discover patterns of activities on the graph and learn predictive models of those discovered patterns. This document outlines the application programming interface (API) requirements for fast prototyping of feature extraction, learning, and prediction algorithms on large dynamic semantic graphs. Since our algorithms must operate on large-scale dynamic semantic graphs, we have chosen to use the graph API developed in the CASC Complex Networks Project. This API is supported on the back end by a semantic graph database (developed by Scott Kohn and his team). The advantages of using this API are (i) we have full-control of its development and (ii) the current API meets almost all of the requirements outlined in this document.

    Sacbrood virus(SBV) is one of the most destructive viruses in the Asian honeybeeApis ceranabut is much less destructive inApis mellifera In previous studies, SBV isolates infectingA. cerana(AcSBV) and SBV isolates infectingA. mellifera(AmSBV) were identified as different serotypes, suggesting a species barrier in SBV infection. In order to investigate this species isolation, we examined the presence of SBV infection in 318A. melliferacolonies and 64A. ceranacolonies, and we identified the genotypes of SBV isolates. We also performed artificial infection experiments under both laboratory and field conditions. The results showed that 38A. melliferacolonies and 37A. ceranacolonies were positive for SBV infection. Phylogenetic analysis based on RNA-dependent RNA polymerase (RdRp) gene sequences indicated thatA. ceranaisolates and mostA. melliferaisolates formed two distinct clades but two strains isolated fromA. melliferawere clustered with theA. ceranaisolates. In the artificial-infection experiments, AcSBV negative-strand RNA could be detected in both adult bees and larvae ofA. mellifera, although there were no obvious signs of the disease, demonstrating the replication of AcSBV inA. mellifera Our results suggest that AcSBV is able to infectA. melliferacolonies with low prevalence (0.63% in this study) and pathogenicity. This work will help explain the different susceptibilities ofA. ceranaandA. melliferato sacbrood disease and is potentially useful for guiding beekeeping practices. PMID:26801569

  9. Internet SCADA Utilizing API's as Data Source

    Robles, Rosslin John; Kim, Haeng-Kon; Kim, Tai-Hoon

    An Application programming interface or API is an interface implemented by a software program that enables it to interact with other software. Many companies provide free API services which can be utilized in Control Systems. SCADA is an example of a control system and it is a system that collects data from various sensors at a factory, plant or in other remote locations and then sends this data to a central computer which then manages and controls the data. In this paper, we designed a scheme for Weather Condition in Internet SCADA Environment utilizing data from external API services. The scheme was designed to double check the weather information in SCADA.

    Calibrations and conditions databases can be accessed from within the JANA Event Processing framework through the API defined in its JCalibration base class. The API is designed to support everything from databases, to web services to flat files for the backend. A Web Service backend using the gSOAP toolkit has been implemented which is particularly interesting since it addresses many modern cybersecurity issues including support for SSL. The API allows constants to be retrieved through a single line of C++ code with most of the context, including the transport mechanism, being implied by the run currently being analyzed and the environment relieving developers from implementing such details.

    This paper describes a software architecture for industrial robots used in manufacturing equipment. In order to achieve software portability, the application software is dissociated from the low-level robot controller software. The interaction between these two pieces of software is achieved by a portable application programming interface (API) for industrial robots. We discuss the requirements for such an API, and propose a design called PINROB.

    Full Text Available Entomopalynological studies of Asteraceae in Argentina revealed that 64 taxa occurred in food stored by honeybees. The most visited plant tribes were classified according to both the type of reward provided by the different taxa and the intensity that such reward is collected by honeybees. Exotic plant taxa were intensely visited inside the disturbed areas (e.g. Cardueae and Cichorieae tribes, whereas native taxa (e.g. Barnadesioideae, Mutisieae, Astereae and Eupatorieae were intensely visited in less disturbed areas. A large number of identified taxa of Asteraceae and the evaluation of its importance to honeybee nutrition were presented. The present study contributes to the knowledge of relationship between Asteraceae and honeybees.A partir de estudios entomopalinológicos se encontró que 64 taxa pertenecientes a la familia Asteraceae están presentes en los alimentos almacenados por las abejas melíferas.

The results of the research are not yet finalised, but the contribution is already emerging of this work to the debate about APIs being either the way forward for digital cultural heritage collections, or the Emperor’s New Clothes (or maybe a bit of both.

    Full Text Available An experiment was conducted to determine the foraging behavior of Apis mellifera L. and Apis cerana F. in rapeseed under cage condition in Chitwan, Nepal during 2012-2013. This experiment showed that Apis cerana F. foraged extra 42 minute per day as compared to Apis mellifera L. Apis cerana F. were more attracted to nectar, whereas Apis mellifera L. were more attracted to pollen collection throughout the day. The activities, in into hives and out from hives, for both species were recorded more at 2:00 pm and least at 8:00 am. The highest in-out were observed at 2:00 pm on both species as Apis mellifera L. 44.33 bees entered into hives and 49.66 bees went out of hives, whereas lower number of Apis cerana F. 43.66 bees entered into hives and 48.16 bees were out of hives. Apis mellifera L. collect 1.22:1 and 0.41:1 pollen nectar ratio at 10:00 am and 4:00 am whereas at same hours Apis cerana collect 1.16:1 and 0.30:1 pollen nectar ratio. Apis cerana F. foraged significantly higher number of rapeseed flowers and plants as compared to Apis mellifera L. under caged condition. It shows that Apis cerana F. was more efficient pollinator as compared to Apis mellifera L. under caged condition.

  6. Comparative virulence and competition between Nosema apis and Nosema ceranae in honey bees (Apis mellifera).

    Milbrath, Meghan O; van Tran, Toan; Huang, Wei-Fong; Solter, Leellen F; Tarpy, David R; Lawrence, Frank; Huang, Zachary Y

    2015-02-01

    Honey bees (Apis mellifera) are infected by two species of microsporidia: Nosema apis and Nosemaceranae. Epidemiological evidence indicates that N. ceranae may be replacing N. apis globally in A. mellifera populations, suggesting a potential competitive advantage of N. ceranae. Mixed infections of the two species occur, and little is known about the interactions among the host and the two pathogens that have allowed N. ceranae to become dominant in most geographical areas. We demonstrated that mixed Nosema species infections negatively affected honey bee survival (median survival=15-17days) more than single species infections (median survival=21days and 20days for N. apis and N. ceranae, respectively), with median survival of control bees of 27days. We found similar rates of infection (percentage of bees with active infections after inoculation) for both species in mixed infections, with N. apis having a slightly higher rate (91% compared to 86% for N. ceranae). We observed slightly higher spore counts in bees infected with N. ceranae than in bees infected with N. apis in single microsporidia infections, especially at the midpoint of infection (day 10). Bees with mixed infections of both species had higher spore counts than bees with single infections, but spore counts in mixed infections were highly variable. We did not see a competitive advantage for N. ceranae in mixed infections; N. apis spore counts were either higher or counts were similar for both species and more N. apis spores were produced in 62% of bees inoculated with equal dosages of the two microsporidian species. N. ceranae does not, therefore, appear to have a strong within-host advantage for either infectivity or spore growth, suggesting that direct competition in these worker bee mid-guts is not responsible for its apparent replacement of N. apis.

    Recent advancements in technology and methodology have led to growing amounts of increasingly complex neuroscience data recorded from various species, modalities, and levels of study. The rapid data growth has made efficient data access and flexible, machine-readable data annotation a crucial requisite for neuroscientists. Clear and consistent annotation and organization of data is not only an important ingredient for reproducibility of results and re-use of data, but also essential for collaborative research and data sharing. In particular, efficient data management and interoperability requires a unified approach that integrates data and metadata and provides a common way of accessing this information. In this paper we describe GNData, a data management platform for neurophysiological data. GNData provides a storage system based on a data representation that is suitable to organize data and metadata from any electrophysiological experiment, with a functionality exposed via a common application programming interface (API). Data representation and API structure are compatible with existing approaches for data and metadata representation in neurophysiology. The API implementation is based on the Representational State Transfer (REST) pattern, which enables data access integration in software applications and facilitates the development of tools that communicate with the service. Client libraries that interact with the API provide direct data access from computing environments like Matlab or Python, enabling integration of data management into the scientist's experimental or analysis routines.

  18. API and ISO standards can be combined

    This paper reports that oil field equipment and product manufacturers can maintain a competitive advantage and minimize costs by integrating American Petroleum Institute (API) licensing programs with International Standards Organization (ISO) 9001 standards under one quality system. A combined quality system approach can position a company for quality system certification under ISO 9001 while maintaining API specifications. Furthermore, only one quality system manual is needed for API licensing and ISO certification, avoiding duplication of effort. The benefits of a documented quality program include the flowing: Job descriptions and personnel qualification requirements are documented; The improved documentation allows direct tracing of specific production activities; Laboratory test methods and calibration of test equipment follow accepted standards for more reliable and reproducible test data; Quality control becomes proactive, not reactive, through internal process controls previously not implemented; Employee attitudes improve through appreciation for the overall goals of the company; Ambiguous quality issues, such as documenting special customer requirements, are easily resolved; and The company image improves with customers, particularly for those that require API Specification Q1 or ISO 9001 compliance or those having their own quality performance standards

  19. Using USNO's API to Obtain Data

    Lesniak, Michael V.; Pozniak, Daniel; Punnoose, Tarun

    2015-01-01

    The U.S. Naval Observatory (USNO) is in the process of modernizing its publicly available web services into APIs (Application Programming Interfaces). Services configured as APIs offer greater flexibility to the user and allow greater usage. Depending on the particular service, users who implement our APIs will receive either a PNG (Portable Network Graphics) image or data in JSON (JavaScript Object Notation) format. This raw data can then be embedded in third-party web sites or in apps.Part of the USNO's mission is to provide astronomical and timing data to government agencies and the general public. To this end, the USNO provides accurate computations of astronomical phenomena such as dates of lunar phases, rise and set times of the Moon and Sun, and lunar and solar eclipse times. Users who navigate to our web site and select one of our 18 services are prompted to complete a web form, specifying parameters such as date, time, location, and object. Many of our services work for years between 1700 and 2100, meaning that past, present, and future events can be computed. Upon form submission, our web server processes the request, computes the data, and outputs it to the user.Over recent years, the use of the web by the general public has vastly changed. In response to this, the USNO is modernizing its web-based data services. This includes making our computed data easier to embed within third-party web sites as well as more easily querying from apps running on tablets and smart phones. To facilitate this, the USNO has begun converting its services into APIs. In addition to the existing web forms for the various services, users are able to make direct URL requests that return either an image or numerical data.To date, four of our web services have been configured to run with APIs. Two are image-producing services: "Apparent Disk of a Solar System Object" and "Day and Night Across the Earth." Two API data services are "Complete Sun and Moon Data for One Day" and "Dates

  2. Linked Vocabulary API for the Earth Sciences Community

    Zednik, S.; Fox, P. A.; Fu, L.; West, P.; Ma, X.

    2014-12-01

    The Linked Vocabulary API is a specification for publishing RESTful APIs of vocabularies represented in the Simple Knowledge Organization System (SKOS) as Linked Data on the web. This work began as part of the Coastal and Marine Spatial Planning Vocabularies (CMSPV) project in response to the need for a standard manner for agencies to publish and consume hierarchical vocabularies on the web. The RESTful architecture of the API provides a simple mechanism for consumption of full vocabularies, single vocabulary terms, related terms, and searches on terms. The Linked Data nature of the API promotes interoperability by exposing vocabulary resources as resolvable URIs that may be referenced from other vocabularies or sources of Linked Data and by allowing the published vocabulary to contain references as links to terms from other vocabularies. The Linked Vocabulary API is formally defined in a Linked Data API specification and may be deployed using standard implementations of the Linked Data API such as the Epimorphics Linked Data API (ELDA). Recent presentations of work done with the Linked Vocabulary API as part of the CMSPV project have resulted in the API receiving growing interest from the broader scientific community. In this contribution we present the Linked Vocabulary API design and deployment process.

Los resultados mostraron que los panales viejos presentaron niveles de infestación significativamente superiores a los registrados en panales nuevos (13,52% ± 3,35 y 6,18% ± 2,12 respectivamente; t = 10,62; p = 1,9 E-9; g. l.= 19. El mismo patrón fue observado en el número promedio de ácaros por panal (443,3 ± 70,54 y 217,85 ± 51,76 para panales viejos y nuevos respectivamente; t = 23,87; p = 1,24 E-15; g. l.= 19. Los ácaros presentan una marcada preferencia por los panales viejos. Esta selección estaría guiada por olores propios de las celdas, que actuarían como atrayentes. Además, posiblemente enmascaran su presencia de esta manera y evitan así ser detectados y eliminados por las abejas nodrizas mediante los comportamientos higiénicos.The aim of this work was to

  10. Population Genetics of Nosema apis and Nosema ceranae: One Host (Apis mellifera) and Two Different Histories

    Two microsporidians are known to infect honey bees: Nosema apis and Nosema ceranae. Whereas population genetics data for the latter have been released in the last few years, such information is still missing for N. apis. Here we analyze the patterns of nucleotide polymorphism at three single-copy loci (PTP2, PTP3 and RPB1) in a collection of Apis mellifera isolates from all over the world, naturally infected either with N. apis (N = 22) or N. ceranae (N = 23), to provide new insights into the genetic diversity, demography and evolution of N. apis, as well as to compare them with evidence from N. ceranae. Neutral variation in N. apis and N. ceranae is of the order of 1%. This amount of diversity suggests that there is no substantial differentiation between the genetic content of the two nuclei present in these parasites, and evidence for genetic recombination provides a putative mechanism for the flow of genetic information between chromosomes. The analysis of the frequency spectrum of neutral variants reveals a significant surplus of low frequency variants, particularly in N. ceranae, and suggests that the populations of the two pathogens are not in mutation-drift equilibrium and that they have experienced a population expansion. Most of the variation in both species occurs within honey bee colonies (between 62%-90% of the total genetic variance), although in N. apis there is evidence for differentiation between parasites isolated from distinct A. mellifera lineages (20%-34% of the total variance), specifically between those collected from lineages A and C (or M). This scenario is consistent with a long-term host-parasite relationship and contrasts with the lack of differentiation observed among host-lineages in N. ceranae (< 4% of the variance), which suggests that the spread of this emergent pathogen throughout the A. mellifera worldwide population is a recent event.

  14. Effects of Nosema apis, N. ceranae, and coinfections on honey bee (Apis mellifera) learning and memory.

    Charbonneau, Lise R; Hillier, Neil Kirk; Rogers, Richard E L; Williams, Geoffrey R; Shutler, Dave

    2016-01-01

    Western honey bees (Apis mellifera) face an increasing number of challenges that in recent years have led to significant economic effects on apiculture, with attendant consequences for agriculture. Nosemosis is a fungal infection of honey bees caused by either Nosema apis or N. ceranae. The putative greater virulence of N. ceranae has spurred interest in understanding how it differs from N. apis. Little is known of effects of N. apis or N. ceranae on honey bee learning and memory. Following a Pavlovian model that relies on the proboscis extension reflex, we compared acquisition learning and long-term memory recall of uninfected (control) honey bees versus those inoculated with N. apis, N. ceranae, or both. We also tested whether spore intensity was associated with variation in learning and memory. Neither learning nor memory differed among treatments. There was no evidence of a relationship between spore intensity and learning, and only limited evidence of a negative effect on memory; this occurred only in the co-inoculation treatment. Our results suggest that if Nosema spp. are contributing to unusually high colony losses in recent years, the mechanism by which they may affect honey bees is probably not related to effects on learning or memory, at least as assessed by the proboscis extension reflex.

This paper presents the design and the results of an empirical study on the directives of API documentation of object-oriented libraries. Its main contribution is to propose and extensively discuss a taxonomy of 23 kinds of API directives.

  20. Rare royal families in honeybees, Apis mellifera

    Moritz, Robin F. A.; Lattorff, H. Michael G.; Neumann, Peter; Kraus, F. Bernhard; Radloff, Sarah E.; Hepburn, H. Randall

    2005-10-01

    The queen is the dominant female in the honeybee colony, Apis mellifera, and controls reproduction. Queen larvae are selected by the workers and are fed a special diet (royal jelly), which determines caste. Because queens mate with many males a large number of subfamilies coexist in the colony. As a consequence, there is a considerable potential for conflict among the subfamilies over queen rearing. Here we show that honeybee queens are not reared at random but are preferentially reared from rare “royal” subfamilies, which have extremely low frequencies in the colony's worker force but a high frequency in the queens reared.

    2013-05-01

    Increased HPC capability comes with increased complexity, part counts, and fault occurrences. In- creasing the resilience of systems and applications to faults is a critical requirement facing the viability of exascale systems, as the overhead of traditional checkpoint/restart is projected to outweigh its bene ts due to fault rates outpacing I/O bandwidths. As faults occur and propagate throughout hardware and software layers, pervasive noti cation and handling mechanisms are necessary. This report describes an initial investigation of fault types and programming interfaces to mitigate them. Proof-of-concept APIs are presented for the frequent and important cases of memory errors and node failures, and a strategy proposed for lesystem failures. These involve changes to the operating system, runtime, I/O library, and application layers. While a single API for fault handling among hardware and OS and application system-wide remains elusive, the e ort increased our understanding of both the mountainous challenges and the promising trailheads. 3

  7. Hymenoptera venom review focusing on Apis mellifera

    P. R. de Lima

    2003-01-01

    Full Text Available Hymenoptera venoms are complex mixtures containing simple organic molecules, proteins, peptides, and other bioactive elements. Several of these components have been isolated and characterized, and their primary structures determined by biochemical techniques. These compounds are responsible for many toxic or allergic reactions in different organisms, such as local pain, inflammation, itching, irritation, and moderate or severe allergic reactions. The most extensively characterized Hymenoptera venoms are bee venoms, mainly from the Apis genus and also from social wasps and ant species. However, there is little information about other Hymenoptera groups. The Apis venom presents high molecular weight molecules - enzymes with a molecular weight higher than 10.0 kDa - and peptides. The best studied enzymes are phospholipase A2, responsible for cleaving the membrane phospholipids, hyaluronidase, which degrades the matrix component hyaluronic acid into non-viscous segments and acid phosphatase acting on organic phosphates. The main peptide compounds of bee venom are lytic peptide melittin, apamin (neurotoxic, and mastocyte degranulating peptide (MCD.

  10. Compositional mining of multiple object API protocols through state abstraction.

    Dai, Ziying; Mao, Xiaoguang; Lei, Yan; Qi, Yuhua; Wang, Rui; Gu, Bin

    2013-01-01

    API protocols specify correct sequences of method invocations. Despite their usefulness, API protocols are often unavailable in practice because writing them is cumbersome and error prone. Multiple object API protocols are more expressive than single object API protocols. However, the huge number of objects of typical object-oriented programs poses a major challenge to the automatic mining of multiple object API protocols: besides maintaining scalability, it is important to capture various object interactions. Current approaches utilize various heuristics to focus on small sets of methods. In this paper, we present a general, scalable, multiple object API protocols mining approach that can capture all object interactions. Our approach uses abstract field values to label object states during the mining process. We first mine single object typestates as finite state automata whose transitions are annotated with states of interacting objects before and after the execution of the corresponding method and then construct multiple object API protocols by composing these annotated single object typestates. We implement our approach for Java and evaluate it through a series of experiments. PMID:23844378

  11. The IRMIS object model and services API

    The relational model developed for the Integrated Relational Model of Installed Systems (IRMIS) toolkit has been successfully used to capture the Advanced Photon Source (APS) control system software (EPICS process variables and their definitions). The relational tables are populated by a crawler script that parses each Input/Output Controller (IOC) start-up file when an IOC reboot is detected. User interaction is provided by a Java Swing application that acts as a desktop for viewing the process variable information. Mapping between the display objects and the relational tables was carried out with the Hibernate Object Relational Modeling (ORM) framework. Work is well underway at the APS to extend the relational modeling to include control system hardware. For this work, due in part to the complex user interaction required, the primary application development environment has shifted from the relational database view to the object oriented (Java) perspective. With this approach, the business logic is executed in Java rather than in SQL stored procedures. This paper describes the object model used to represent control system software, hardware, and interconnects in IRMIS. We also describe the services API used to encapsulate the required behaviors for creating and maintaining the complex data. In addition to the core schema and object model, many important concepts in IRMIS are captured by the services API. IRMIS is an ambitious collaborative effort for defining and developing a relational database and associated applications to comprehensively document the large and complex EPICS-based control systems of today's accelerators. The documentation effort includes process variables, control system hardware, and interconnections. The approach could also be used to document all components of the accelerator, including mechanical, vacuum, power supplies, etc. One key aspect of IRMIS is that it is a documentation framework, not a design and development tool. We do not

  20. GIANT API: an application programming interface for functional genomics.

    Roberts, Andrew M; Wong, Aaron K; Fisk, Ian; Troyanskaya, Olga G

    2016-07-01

    GIANT API provides biomedical researchers programmatic access to tissue-specific and global networks in humans and model organisms, and associated tools, which includes functional re-prioritization of existing genome-wide association study (GWAS) data. Using tissue-specific interaction networks, researchers are able to predict relationships between genes specific to a tissue or cell lineage, identify the changing roles of genes across tissues and uncover disease-gene associations. Additionally, GIANT API enables computational tools like NetWAS, which leverages tissue-specific networks for re-prioritization of GWAS results. The web services covered by the API include 144 tissue-specific functional gene networks in human, global functional networks for human and six common model organisms and the NetWAS method. GIANT API conforms to the REST architecture, which makes it stateless, cacheable and highly scalable. It can be used by a diverse range of clients including web browsers, command terminals, programming languages and standalone apps for data analysis and visualization. The API is freely available for use at http://giant-api.princeton.edu. PMID:27098035

  4. The Apis mellifera Filamentous Virus Genome

    Laurent Gauthier

    2015-07-01

    Full Text Available A complete reference genome of the Apis mellifera Filamentous virus (AmFV was determined using Illumina Hiseq sequencing. The AmFV genome is a double stranded DNA molecule of approximately 498,500 nucleotides with a GC content of 50.8%. It encompasses 247 non-overlapping open reading frames (ORFs, equally distributed on both strands, which cover 65% of the genome. While most of the ORFs lacked threshold sequence alignments to reference protein databases, twenty-eight were found to display significant homologies with proteins present in other large double stranded DNA viruses. Remarkably, 13 ORFs had strong similarity with typical baculovirus domains such as PIFs (per os infectivity factor genes: pif-1, pif-2, pif-3 and p74 and BRO (Baculovirus Repeated Open Reading Frame. The putative AmFV DNA polymerase is of type B, but is only distantly related to those of the baculoviruses. The ORFs encoding proteins involved in nucleotide metabolism had the highest percent identity to viral proteins in GenBank. Other notable features include the presence of several collagen-like, chitin-binding, kinesin and pacifastin domains. Due to the large size of the AmFV genome and the inconsistent affiliation with other large double stranded DNA virus families infecting invertebrates, AmFV may belong to a new virus family.

  5. Honeybee (Apis mellifera ligustica) drone embryo proteomes.

    2011-03-01

    Little attention has been paid to the drone honeybee (Apis mellifera ligustica) which is a haploid individual carrying only the set of alleles that it inherits from its mother. Molecular mechanisms underlying drone embryogenesis are poorly understood. This study evaluated protein expression profiles of drone embryogenesis at embryonic ages of 24, 48 and 72h. More than 100 reproducible proteins were analyzed by mass spectrometry on 2D electrophoresis gels. Sixty-two proteins were significantly changed at the selected three experimental age points. Expression of the metabolic energy requirement-related protein peaked at the embryonic age of 48h, whereas development and metabolizing amino acid-related proteins expressed optimally at 72h. Cytoskeleton, protein folding and antioxidant-related proteins were highly expressed at 48 and 72h. Protein networks of the identified proteins were constructed and protein expressions were validated at the transcription level. This first proteomic study of drone embryogenesis in the honeybee may provide geneticists an exact timetable and candidate protein outline for further manipulations of drone stem cells.

  6. Magnetoreception system in honeybees (Apis mellifera.

    Chin-Yuan Hsu

    Full Text Available Honeybees (Apis mellifera undergo iron biomineralization, providing the basis for magnetoreception. We showed earlier the presence of superparamagnetic magnetite in iron granules formed in honeybees, and subscribed to the notion that external magnetic fields may cause expansion or contraction of the superparamagnetic particles in an orientation-specific manner, relaying the signal via cytoskeleton (Hsu and Li 1994. In this study, we established a size-density purification procedure, with which quantitative amount of iron granules was obtained from honey bee trophocytes and characterized; the density of iron granules was determined to be 1.25 g/cm(3. While we confirmed the presence of superparamagnetic magnetite in the iron granules, we observed changes in the size of the magnetic granules in the trophycytes upon applying additional magnetic field to the cells. A concomitant release of calcium ion was observed by confocal microscope. This size fluctuation triggered the increase of intracellular Ca(+2 , which was inhibited by colchicines and latrunculin B, known to be blockers for microtubule and microfilament syntheses, respectively. The associated cytoskeleton may thus relay the magnetosignal, initiating a neural response. A model for the mechanism of magnetoreception in honeybees is proposed, which may be applicable to most, if not all, magnetotactic organisms.

  7. Inhibiting DNA methylation alters olfactory extinction but not acquisition learning in Apis cerana and Apis mellifera.

    Gong, Zhiwen; Wang, Chao; Nieh, James C; Tan, Ken

    2016-07-01

    DNA methylation plays a key role in invertebrate acquisition and extinction memory. Honey bees have excellent olfactory learning, but the role of DNA methylation in memory formation has, to date, only been studied in Apis mellifera. We inhibited DNA methylation by inhibiting DNA methyltransferase (DNMT) with zebularine (zeb) and studied the resulting effects upon olfactory acquisition and extinction memory in two honey bee species, Apis cerana and A. mellifera. We used the proboscis extension reflex (PER) assay to measure memory. We provide the first demonstration that DNA methylation is also important in the olfactory extinction learning of A. cerana. DNMT did not reduce acquisition learning in either species. However, zeb bidirectionally and differentially altered extinction learning in both species. In particular, zeb provided 1h before acquisition learning improved extinction memory retention in A. mellifera, but reduced extinction memory retention in A. cerana. The reasons for these differences are unclear, but provide a basis for future studies to explore species-specific differences in the effects of methylation on memory formation. PMID:27262427

    2003-10-01

    Full Text Available Abstract Background Biological data resources have become heterogeneous and derive from multiple sources. This introduces challenges in the management and utilization of this data in software development. Although efforts are underway to create a standard format for the transmission and storage of biological data, this objective has yet to be fully realized. Results This work describes an application programming interface (API that provides a framework for developing an effective biological knowledge ontology for Java-based software projects. The API provides a robust framework for the data acquisition and management needs of an ontology implementation. In addition, the API contains classes to assist in creating GUIs to represent this data visually. Conclusions The Knowledge Discovery Object Model (KDOM API is particularly useful for medium to large applications, or for a number of smaller software projects with common characteristics or objectives. KDOM can be coupled effectively with other biologically relevant APIs and classes. Source code, libraries, documentation and examples are available at http://www.bcgsc.ca/bioinfo/software.

    Abstract. The mite Varroa destructor (Anderson & Trueman, has been, until now, one of the pest that causes more damage to the beekeeping worldwide, alone or associated with another bee diseases. Several factors affects the variation of the indexes of infestation and reproduction, such as climate, bee breed, development time, hygienic behavior; being that temperature is a environmental variable that acts on the variation of these indexes: the infestation increases in the colder months and decrease in warmer months, so in the months of autumn and winter occurs the biggest infestation by varroa in the beehives. Were evaluated the indexes of infestation by V. destructor on adult worker and brood cells to ascertain how these indexes rates, in months of autumn, in an africanized bees apiary located in region of Cerrado, surrounded by plantations of sugar cane, with a tropical climate and food in nature. The sample was collected in two years, in the months of May and June 2005 and April and June 2007 in the Experimental Apiary of Franca University-UNIFRAN, located in the municipality of Restiga-SP. The medium indexes of infestation in broods were higher in May/2005 (12.44% than June/2005 (7.78%, were also higher in April/2007 (3% than in June/2007 (0%; all the differences weren’t statistically significant. The medium indexes of infestation in adult workers were lesser in May/2005 (0.95% than June/2005 (1.90% and lesser in April/2007 (0.90% than in June/2007 (4.43%; the difference observed in 2005 was not statistically significant, unlike that observed in 2007 (P=0.031.

  3. PrismTech Data Distribution Service Java API Evaluation

    Riggs, Cortney

    2008-01-01

    My internship duties with Launch Control Systems required me to start performance testing of an Object Management Group's (OMG) Data Distribution Service (DDS) specification implementation by PrismTech Limited through the Java programming language application programming interface (API). DDS is a networking middleware for Real-Time Data Distribution. The performance testing involves latency, redundant publishers, extended duration, redundant failover, and read performance. Time constraints allowed only for a data throughput test. I have designed the testing applications to perform all performance tests when time is allowed. Performance evaluation data such as megabits per second and central processing unit (CPU) time consumption were not easily attainable through the Java programming language; they required new methods and classes created in the test applications. Evaluation of this product showed the rate that data can be sent across the network. Performance rates are better on Linux platforms than AIX and Sun platforms. Compared to previous C++ programming language API, the performance evaluation also shows the language differences for the implementation. The Java API of the DDS has a lower throughput performance than the C++ API.

  4. API manager implementation and its use for Indus accelerator control

    The control system software needed for operation of Indus accelerators is coupled to the underlying firmware and hardware of the control system by the Application Programming Interface (API) manager. In the three layered architecture of Indus control system, PVSS-II SCADA is being used at the layer-1(L1) for control and monitoring of various sub-systems. The layer-2(L2) consists of VME bus based system. The API manager plays a crucial role in interfacing the L1 and L2 of the control system. It has to interact with both the PVSS database and the L2. In order to access the PVSS database it uses the PVSS API, a C++ class library, whereas in order to access the L2 custom functions have been built. Several other custom functionalities have also been implemented. The paper presents the important aspects of the API manager like its implementation, its interface mechanism to the lower layer and features like configurability, reusable classes, multithreading capability etc. (author)

Invasive Nosema ceranae is particularly worrisome because some evidence suggests it has greater virulence than its congener N. apis. N. ceranae appears to have recently switched hosts from Asian honey bees (Apis cerana) and now has a nearly global distribution in honey bees, apparently displacing ...

  11. Africanized honey bees (Apis mellifera L. are more efficient at removing worker brood artificially infested with the parasitic mite Varroa jacobsoni Oudemans than are Italian bees or Italian/Africanized hybrids

    Full Text Available Africanized honey bees are more tolerant of infestations with the mite Varroa jacobsoni than are honey bees of European origin. The capacity of these bees to detect and react to brood infested with this mite could be one of the factors determining this tolerance. We tested colonies of Africanized bees headed by queens from swarms collected in Ribeirão Preto, São Paulo State. The Italian colonies had queens imported directly from the USA, or from the Brazilian Island of Fernando de Noronha, where varroa-infested Italian colonies have been maintained, untreated, since 1984. Recently sealed worker brood cells were artificially infested by opening the cell capping, inserting live adult female mites and resealing the cells. Control cells were treated in the same way, but without introducing mites. The ability of the Africanized honey bees to recognize and remove this artificially infested brood was compared with that of first generation Italian/Africanized hybrid bees, and with the two groups of "pure" Italian bees, in three separate experiments. Africanized colonies removed a mean of 51% of the infested brood, while Italian/Africanized hybrid colonies removed 25%. Africanized colonies also removed a significantly greater proportion of infested brood than did Italian colonies, headed by queens from the USA (59 vs. 31%, respectively. Similarly, when Africanized colonies were compared with colonies of Italian bees from Fernando de Noronha, the former were found to be significantly more efficient at removing infested brood (61 vs. 35%, respectively, even though the population of Italian bees on this island has been exposed to and survived varroa infestations (without treatment for more than 12 years. Only the Africanized honey bees removed a significant proportion of varroa-infested brood, when the data was corrected for brood removal from control cells.Abelhas africanizadas são mais tolerantes à infestação com o ácaro Varroa jacobsoni do que

    Full Text Available El uso de la miel en medicina tradicional y complementaria/alternativa necesita evidencias para explicar las características bioactivas de este producto de la colmena. Las técnicas analíticas sugeridas por la Comisión del Codex Alimentarius para la inocuidad y los propósitos del control de calidad y de comercialización, no son suficientes para diferenciar este complejo producto de las abejas, aparentemente homogéneo. En este trabajo se midió la capacidad antioxidante de la miel producida por los géneros Apis, Melipona y Trigona de Venezuela, utilizando tres sistemas oxidativos, para probar la eficacia de la miel en la inhibición del anión del superóxido (O2●-, la formación del radical hidroxilo (OH● y la degradación del benzoato (AOA. Todas las muestras de miel genuina diluida presentaron indicadores antioxidantes más altos que los de la miel artificial y del ácido lipoico utilizado como control antioxidante suave. Sin embargo, la melatonina y la quercetina, los controles antioxidantes potentes usados aquí, fueron mejores limpiadores que las mieles genuinas en los análisis de OH● y del AOA, que son sistemas generadores de radicales hidroxilo. Ésta es la primera vez que se utiliza AOA para determinar la capacidad antioxidante de la miel. Además de su uso para medir características bioactivas, los indicadores de capacidad antioxidante aquí usados podrían proponerse en como análisis para controlar la miel adulterada. El origen entomológico no se relacionó con las características antioxidantes de la mielThe use of honey in traditional and complementary/alternative medicine needs evidence to explain the bioactive properties of this product from the hive. The analytical techniques of the Codex Alimentarius Commission for safety and trading quality control purposes, are not sufficient to differentiate this apparently homogeneus but complex bee product.

  13. Changes in Alternative Splicing in Apis Mellifera Bees Fed Apis Cerana Royal Jelly

    Full Text Available The Western honey bee (Apis mellifera is a social insect characterized by caste differentiation in which the queen bee and worker bees display marked differences in morphology, behavior, reproduction, and longevity despite their identical genomes. The main causative factor in caste differentiation is the food fed to queen larvae, termed royal jelly (RJ. Alternative splicing (AS is an important RNA-mediated post-transcriptional process in eukaryotes. Here we report AS changes in A. mellifera after being fed either A. mellifera RJ or A. cerana RJ. The results demonstrated that the RJ type affected 4 types of AS in adult A. mellifera: exon skipping, intron retention, alternative 5’ splice sites, and alternative 3’splice sites. After feeding with A. cerana RJ, AS occurred in many genes in adult A. mellifera that encode proteins involved in development, growth, the tricarboxylic acid cycle, and substance metabolism. This study provides the first evidence that heterospecific RJ can influence the AS of many genes related to honey bee development and growth.

  14. Host Specificity in the Honeybee Parasitic Mite, Varroa spp. in Apis mellifera and Apis cerana.

    The ectoparasitic mite Varroa destructor is a major global threat to the Western honeybee Apis mellifera. This mite was originally a parasite of A. cerana in Asia but managed to spill over into colonies of A. mellifera which had been introduced to this continent for honey production. To date, only two almost clonal types of V. destructor from Korea and Japan have been detected in A. mellifera colonies. However, since both A. mellifera and A. cerana colonies are kept in close proximity throughout Asia, not only new spill overs but also spill backs of highly virulent types may be possible, with unpredictable consequences for both honeybee species. We studied the dispersal and hybridisation potential of Varroa from sympatric colonies of the two hosts in Northern Vietnam and the Philippines using mitochondrial and microsatellite DNA markers. We found a very distinct mtDNA haplotype equally invading both A. mellifera and A. cerana in the Philippines. In contrast, we observed a complete reproductive isolation of various Vietnamese Varroa populations in A. mellifera and A. cerana colonies even if kept in the same apiaries. In light of this variance in host specificity, the adaptation of the mite to its hosts seems to have generated much more genetic diversity than previously recognised and the Varroa species complex may include substantial cryptic speciation.

  17. Infra-population and -community dynamics of the parasites Nosema apis and Nosema ceranae, and consequences for honey bee (Apis mellifera hosts.

    Geoffrey R Williams

    Full Text Available Nosema spp. fungal gut parasites are among myriad possible explanations for contemporary increased mortality of western honey bees (Apis mellifera, hereafter honey bee in many regions of the world. Invasive Nosema ceranae is particularly worrisome because some evidence suggests it has greater virulence than its congener N. apis. N. ceranae appears to have recently switched hosts from Asian honey bees (Apis cerana and now has a nearly global distribution in honey bees, apparently displacing N. apis. We examined parasite reproduction and effects of N. apis, N. ceranae, and mixed Nosema infections on honey bee hosts in laboratory experiments. Both infection intensity and honey bee mortality were significantly greater for N. ceranae than for N. apis or mixed infections; mixed infection resulted in mortality similar to N. apis parasitism and reduced spore intensity, possibly due to inter-specific competition. This is the first long-term laboratory study to demonstrate lethal consequences of N. apis and N. ceranae and mixed Nosema parasitism in honey bees, and suggests that differences in reproduction and intra-host competition may explain apparent heterogeneous exclusion of the historic parasite by the invasive species.

  18. The Auroral Planetary Imaging and Spectroscopy (APIS) service

    Lamy, Laurent; Henry, Florence; Sidaner, Pierre Le

    2015-01-01

    The Auroral Planetary Imaging and Spectroscopy (APIS) service, accessible online, provides an open and interactive access to processed auroral observations of the outer planets and their satellites. Such observations are of interest for a wide community at the interface between planetology and magnetospheric and heliospheric physics. APIS consists of (i) a high level database, built from planetary auroral observations acquired by the Hubble Space Telescope (HST) since 1997 with its mostly used Far-UltraViolet spectro-imagers, (ii) a dedicated search interface aimed at browsing efficiently this database through relevant conditional search criteria and (iii) the ability to interactively work with the data online through plotting tools developed by the Virtual Observatory (VO) community, such as Aladin and Specview. This service is VO compliant and can therefore also been queried by external search tools of the VO community. The diversity of available data and the capability to sort them out by relevant physical...

    Apis mellifera intermissa is the native honeybee subspecies of Algeria. A. m. intermissa occurs in Tunisia, Algeria and Morocco, between the Atlas and the Mediterranean and Atlantic coasts. This bee is very important due to its high ability to adapt to great variations in climatic conditions and due to its preferable cleaning behavior. Here we report the draft genome sequence of this honey bee, its Whole Genome Shotgun project has been deposited at DDBJ/EMBL/GenBank under the accession JSUV00000000. The 240-Mb genome is being annotated and analyzed. Comparison with the genome of other Apis mellifera sub-species promises to yield insights into the evolution of adaptations to high temperature and resistance to Varroa parasite infestation.

  1. “Wrapping” X3DOM around Web Audio API

    Andreas Stamoulias

    2015-12-01

    Full Text Available Spatial sound has a conceptual role in the Web3D environments, due to highly realism scenes that can provide. Lately the efforts are concentrated on the extension of the X3D/ X3DOM through spatial sound attributes. This paper presents a novel method for the introduction of spatial sound components in the X3DOM framework, based on X3D specification and Web Audio API. The proposed method incorporates the introduction of enhanced sound nodes for X3DOM which are derived by the implementation of the X3D standard components, enriched with accessional features of Web Audio API. Moreover, several examples-scenarios developed for the evaluation of our approach. The implemented examples established the achievability of new registered nodes in X3DOM, for spatial sound characteristics in Web3D virtual worlds.

  2. The simulation of CAMAC system based on Windows API

    Based on Windows API, a kind of design method to simulate the CAMAC System, which is commonly used in nuclear physics experiments, is developed. Using C++ object-oriented programming, the simulation is carried out in the environment of Visual Studio 2010 and the interfaces, the data-way, the control commands and the modules are simulated with the functions either user-defined or from Windows API. Applying this method, the amplifier plug AMP575A produced by ORTEC is simulated and performance experiments are studied for this simulation module. The results indicate that the simulation module can fulfill the function of pole-zero adjustment, which means this method is competent for the simulation of CAMAC System. Compared with the simulation based on LabVIEW, this way is more flexible and closer to the bottom of the system. All the works above have found a path to making the virtual instrument platform based on CAMAC system. (authors)

    Honigbienen (Apis mellifera carnica) regulieren die Temperatur ihrer Brut in einem sehr engen Temperaturfenster, da vor allem die gedeckelte Brut sehr temperaturempfindlich reagiert (Groh et al. 2004). Die Thermoregulation ist nicht – wie lange angenommen – Beiprodukt von alltäglichen Arbeiten der Bienen im Brutbereich, sondern eine aktive und Energie- und Zeitaufwändige eigene Tätigkeit. Arbeiterinnen ziehen sich mit ihren Beinen an die Brutoberfläche, drücken ihren warmen Thorax auf die Bru...
