| Honey bees (Apis mellifera) pollinate melon (Cucumis melo) and improve production and quality of fruits. However, little is known about bee behavior and number of hives required. The aims of this study were to compare bees visiting flowers in crop areas with different number of hives (0, 1, 2, and 3), and to evaluate which is the best number. Flowers were observed (n=78) from 5 am to 6 pm, for five consecutive days, in four experimental areas (0.5ha each). Comparisons were made for male (MF) and hermaphrodite (HF) flowers, number of hives and fruit production. The HF were always more visited than MF. Most comparisons made for three hives presented significant differences, since visits increased drastically, competition among bees for floral resources... |

| In true social hymenopterans, such as many species of bees, wasps and all species of ants, the main characteristics are the overlapping of generations, the care with the offspring and the division of labor among the members of the colony. The first biological feature means that in a same moment there are groups of individuals, with variable ages, that execute different activities in the colony. In order to study the division of labor among the members of the colony, or to estimate the life span of these insects, or even to analyze any kind of behavior in non-social insects, it is necessary to know the exact age of each individual. For this reason, the insects must be identified soon after emergence. The identification of insects with numbers is an... |

| La varroosis de las abejas continúa siendo el principal problema sanitario de la apicultura mundial. El control químico ha sido el método de control más empleado pero puede conducir al desarrollo de cepas de ácaros resistentes a los acaricidas, elevar los costos de producción, causar efectos tóxicos en las abejas y el hombre, y contaminar los productos de la colmena, por lo que dificulta su comercialización. Con el propósito de conocer el comportamiento de los índices de infestación por Varroa en colmenas no tratadas, de un apiario de selección natural, se realizó un muestreo mensual de abejas adultas y fragmentos de panales de crías de obreras y zánganos durante 13 meses. En un grupo control se trabajó con seis apiarios con diferente tiempo... |

| The objective of this study was to evaluate the influence of pollinating insects on canola productivity for different commercial hybrids, Hyola 61 and Hyola 433, in Minas Gerais State, Brazil. The studies were conducted at the Fazenda Experimental Água Limpa of the Federal University of Uberlândia. To evaluate the influence of pollination by bees on the production of canola seeds, an experiment was carried out to exclude floral visitors and compare canola seed production following four treatments: (a) autogamy in Hyola 61, (b) autogamy in Hyola 433, (c) open pollination in Hyola 61, with insects having free access, and (d) open pollination in Hyola 433, with insects having free access. Flowers that were available for pollination had 25% and 18.8% heavier... |

| This study was undertaken to develop an experimental protocol using insects as biological models to assay venom toxicity of the following spiders Loxosceles gaucho, Phoneutria nigriventer, Nephilengys cruentata and Tityus serrulatus scorpion. Three different insect species were bioassayed: Apis mellifera (Hymenoptera), Grillus assimilis (Orthoptera), and Diatraea saccharalis (Lepidoptera). Venoms were injected into the hemocele of insects with a microsyringe at concentrations that caused dose/weight-dependent effects; doses causing either paralysis (ED50) or death (LD50) were recorded for each venom and insect test-species. T. serrulatus and L. gaucho venoms were lethal to all tested species, while P. nigriventer venom caused paralysis and death, and N.... |

| Exfoliated vermiculite is a light-weight and cheap product that, because of its thermal resistance, has become a valuable insulating material. With regard to its use in beekeeping, this research tested whether the box for honey bees constructed with cement-vermiculite mortar (CVM) presents physical characteristics similar to those of wood. The experiment was carried out at Seropédica, RJ, Brazil, for eight months. The cement-vermiculite mortar was compared with a control material (pinewood), in the construction of Langstroth boxes and boards, in a completely randomized design, with respect to thermal control, thermal conductivity and its capacity to absorb and lose water. The production cost for a CVM box was estimated. There were no internal temperature... |

| Abstract Background Apis mellifera venom, which has already been recommended as an alternative anti-inflammatory treatment, may be also considered an important source of candidate molecules for biotechnological and biomedical uses, such as the treatment of parasitic diseases. Methods Africanized honeybee venom from Apis mellifera was fractionated by RP-C18-HPLC and the obtained melittin was incubated with promastigotes and intracellular amastigotes of Leishmania (L.) infantum. Cytotoxicity to mice peritoneal macrophages was evaluated through mitochondrial oxidative activity. The production of anti- and pro-inflammatory cytokines, NO and H2O2 by macrophages was determined. Results Promastigotes and intracellular amastigotes were susceptible to melittin... |

| 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... |

| O presente experimento teve como objetivo avaliar métodos de atração da abelha Apis mellifera L. (Hymenoptera, Apidae) em duas variedades de abacate (Persea americana Mill.). Os atrativos utilizados foram extratos de Cymbopogon citratus, Ocimum basilicum, Lippia alba, folha de Citrus sp, folha de Eucaliptus sp. e o eugenol e o linalol (SIGMA). Os tratamentos utilizados foram: coberto; descoberto pulverizado (DP); descoberto com tubos e descoberto não pulverizado (DNP). Observou-se que a atratividade das substâncias testadas desapareceu minutos após a sua aplicação, utilizando ou não a glicerina, em ambas as variedades. A pulverização dos extratos de falsa melissa, folhas de eucalipto e folhas de laranja apresentaram um aumento no número de abelhas Apis... |

| Este estudo objetivou identificar a origem botânica das cargas de pólen coletadas por abelhas africanizadas. Em Piracicaba (SP), foram instaladas, durante as quatro estações do ano, cinco colmeias de A. mellifera com um coletor de pólen frontal em cada uma. A preparação palinológica foi pelo uso de acetólise, sendo identificados e contados aproximadamente 900 grãos de pólen por amostra. A partir da composição polínica, calculou-se a riqueza, os índices de diversidade e equitabilidade. Ao longo do ano, foram encontrados 81 tipos polínicos, pertencentes a 32 famílias botânicas sendo Fabaceae, Asteraceae e Malvaceae, as famílias com maior frequência de tipos polínicos (≥5 tipos polínicos), e Myrtaceae, a família com dois tipos polínicos (Eucalyptus sp. e... |

| The mite Varroa destructor (Anderson & Truemann 2000) (Acari: Varroidae) is one of the most studied parasites of Apis mellifera, as it causes many losses in apicultural business worldwide. Several research studies have demonstrated distinct levels of virulence of the mite and increased colony mortality rates due to its infestation; however only a few studies report the mite's effects on specific tissues, glands or other organs in bees. In this context, this study was conducted with the aim of studying the parasitic effect of the mite V. destructor on hypopharyngeal glands of Africanized A. mellifera. Mean gland cell areas for bees with and without mite infestations were significantly different. Variations in the number of vesicles and the presence of... |

| The increasing demand for propolis has caused a raise in its production. However, an increasingly pesticide-dependent agriculture is a great concern with regard to bees, their produce and environmental contamination. Current analysis evaluates the presence of pesticides (organochlorines, organophosphates, pyrethroids, carbamates, herbicides, fungicides and acaricides) in samples of propolis from the state of São Paulo, Brazil. Beekeepers from several localities in the state provided samples of propolis (50), which were collected, stored in non-toxic plastic bags and maintained in a freezer for analyses. Possible pesticide residues were examined by gas chromatography method but no pesticide residues were detected in the examined propolis samples. Propolis... |
