It has been difficult to manipulate the ultraviolet (UV) reflectance of flowers independently of other wavelengths to study the response of insect pollinators to this trait. One effective solution is to paint flower corollas with human sunscreen that absorbs UV wavelengths. Honeybees (Apis mellifera scutellata) foraging on the strongly UV-reflecting flowers of Hypoxis hemerocallidea Fisch. & C.A. Mey. rejected flowers that had UV reflectance eliminated by a sunscreen coating, but continued to visit control flowers painted with sunscreen solution that did not contain the UV absorbing compound. The sunscreen technique could be useful for determining the response of a wide range of pollinators to the UV component of spectral reflectance in flowers and could be used to test the functional significance of UV-contrasting "nectar guide" patterns.Key words: Apis mellifera scutellata, choice experiment, flower colour, Hypoxis hemerocallidea, pollination, foraging behaviour.

Natural Infestation

Varroa jacobsoni foi descrita em 1904 por Oldenans em Java em cria de Apis cerana. O nível de infestação com V. jacobsoni mede indiretamente o grau de tolerância da A. mellifera à V. jacobsoni. O estudo foi conduzido no Município de Mandirituba-PR. Os enxames foram capturados com caixa iscas. A percentagem de infestação V. jacobsoni foi resistrada mensalmente. Aplicando-se o teste de Friedman e usando-se o rank de cada colônia, separou-se os grupos de colônias homogêneas. A tendência sazonal foi demostrada com representação gráfica. O experimento foi delineado segundo blocos inteiramente casualizados. Em todas as amostras foi encontrado o ácaro V. jacobsoni. Diferenças significativas entre as colônias foram observadas. Na população de Apis mellifera scutellata existem três grupos homogêneos de colônias quanto ao nível de infestação com esse ácaro. O inverno é a época onde o grau de infestação com V. jacobsoni é mais elevado. Natural infestation of Apis mellifera scutellata (Hymenoptera; Apidae) by Varroa jacobsoni (Mesostigmata; Varroidae) Abstract Infestation by Varroa jacobsoni in an offspring of Apis cerana was first described as early as 1904 in Java. Since the level of infestation by V. jacobsoni may be an indirect procedure to measure the Apis mellifera scutellata tolerance degree towards it, the present research was carried out in order to evaluate such biological relationship between host and parasite and its implication in the Apis mellifera scutellata productivity. This study was carried out at Mandirituba, Paraná, Brazil. The swarms were captured with bait boxes. The percentage of V. jacobsoni infestation was established monthly. According to the Friedman test ant through the rank, homogeneous colonies were single out. The experiment has been delineated as entirely randomized blocks.

A polinização é um serviço ecossistêmico de extrema importância no ambiente natural, garantindo muitos benefícios à biodiversidade e à manutenção dos ecossistemas. O presente trabalho teve como objetivo investigar a diversidade da apifauna e delinear as redes de interações entre espécies de plantas e abelhas em áreas de várzea, na Floresta Nacional de Três Barras (SC, Brasil). Foram selecionadas três áreas de várzeas para a amostragem de abelhas nas flores, cada uma com seis parcelas de 1 ha. As coletas ocorreram durante a primavera e o verão de 2016 e 2017. Coletaram-se 1.656 abelhas, distribuídas em 99 espécies. Apidae foi a família mais abundante e Halictidae a família mais rica em espécies. As espécies mais abundantes foram Apis mellifera scutellata, Melipona (Eomelipona) marginata, Plebeia emerina, Trigona spinipes, Rhophitulus flavitarsis, Tetraglossula sp., Scaptotrigona bipunctata, Bombus (Thoracobombus) pauloensis. As interações entre as espécies de abelhas e plantas apresentaram um padrão generalista; a rede mostrou-se significativamente aninhada e modular. A comunidade de abelhas nos campos de várzea evidenciou alta riqueza de espécies em comparação a outros levantamentos na Região Sul do Brasil, especialmente se considerarmos que a área de estudo é um ambiente mais restrito. As espécies mais abundantes foram as eussociais, as quais são diversificadas nas florestas neotropicais, com destaque para Apis mellifera scutellata, uma espécie exótica, bastante populosa e generalista.

Um dos principais objetivos do presente trabalho é o de estudar a seleção de Apis melifera scutellatas em razão de suas características genéticas. Para tal efeito, duas variáveis foram avaliadas: mel e pólen, bem como a separação de dois grupos, um grupo homogêneo superior e um grupo homogêneo inferior. Na área estudada (Mandirituba, Estado do Paraná), quatro estágios successivos de desenvolvimento secundário foram estabelecidos, as colônias sendo habitadas com iscas de captura em colmeias Langsthroth. O experimento foi delineado em blocos randomizados, a oferta de fontes de alimentos = néctar e pólen = estando na direta dependência das condições ambientais. Diferenças significantes foram encontradas entre as colônias, com relação às seguintes variáveis: área, mel e pólen. Abstract One of the aims of the present paper is to study Apis melifera scutellatas’ selection, because of its genetic characteristics. For this purpose, two variables were evaluated: honey and pollen as well as the separation of two groups namely the superior homogeneous group and the inferior homogeneous group. In the studied area (Mandirituba, State of Paraná), four stages of bee’s successional secondary development were established, the colonies being populated with capture baits in Langsthroth’s beehives. The experiment was delineated in randomized blocks, the bee’s availability for food resources = nectar and pollen = being in direct dependence of the environmental conditions. Significant differences were found among the colonies in regard to the following variables: area, honey and pollen.

Winter Crop

Brassica napus Linnaeus is considered a self-compatible crop; however, studies show that bee foraging elevates their seed production. Considering bee food shortages during the winter season and that the canola is a winter crop, this study aimed to evaluate the foraging behaviour of Apis mellifera Linnaeus, 1758 regarding those flowers, and to verify if it presents adequate behaviour for successfully pollinating this crop in Rio Grande do Sul State. The study was carried out in a canola field, in Southern Brazil. The anthesis stages were morphologically characterised and then related to stigma receptivity and pollen grain viability. Similarly, the behaviour of A. mellifera individuals on flowers was followed, considering the number of flowers visited per plant, the amount of time spent on the flowers, touched structures, and collected resources. Floral fidelity was inferred by analysing the pollen load of bees collected on flowers. The bees visited from 1-7 flowers/plant (x = 2.02; sd = 1.16), the time spent on the flowers varied between 1-43 seconds (x = 3.29; sd = 2.36) and, when seeking nectar and pollen, they invariably touched anthers and stigmas. The pollen load presented 100% of B. napus pollen. The bees' attendance to a small number of flowers/plants, their short permanence on flowers, their contact with anthers and stigma and the integral floral constancy allows their consideration as potential B. napus pollinators.

Honeybee Population

Honeybee populations in Côte d’Ivoire have been previously identified as belonging to one subspecies, Apis mellifera scutellata, but other studies have since reported a mixed population consisting of A. m. adansonii and A. m. jemenitica. The population structure and the geographic distribution of honeybees in Côte d’Ivoire remain unclear. This study aimed to profile the population structure of honeybees and their biogeography in Côte d’Ivoire. A total of 33 honeybee colonies were sampled from 15 localities to investigate the maternal ancestry of indigenous honeybee populations using the DraI COI-COII mtDNA test. The results revealed that the honeybee population in Côte d’Ivoire is composed of African haplotypes, all belonging to the AI sublineage. Haplotypes A1 and A4 were recorded with five new sequence variants, including three types of haplotype A1 and two types of haplotype A4. The A1e variant was the most frequent in the A. m. adansonii distributional area. The distribution of the haplotype variants was correlated with the climate pattern in Côte d’Ivoire. This is the first study in Côte d’Ivoire that gives insights into the biogeography and mitotype structure of the local honeybee populations.
