    A jurubeba (Solanum paniculatum) é uma planta medicinal indicada para o tratamento de diferentes tipos de doenças. Ela é um arbusto nativo das regiões Norte e Nordeste do Brasil, possui folhas de sabor amargo e frutos amarelo-esverdeados, que também podem ser incluídos na alimentação. O objetivo deste trabalho foi identificar os visitantes florais da jurubeba, tipo de coleta (pólen, néctar e/ou resina) e a frequência dessas visitações. O experimento foi realizado no Setor de Meliponicultura do Departamento de Zootecnia, na Universidade Federal Rural de Pernambuco, em Recife, PE. As observações foram realizadas das 6h às 16h, nos 10 minutos iniciais de cada horário, com três repetições, em três dias distintos, em janeiro de 2024. Foi observada a presença de várias espécies de abelhas, coletando pólen nas flores da jurubeba, entre elas: Augochloropsis sp. (53,7%), Bombus atratus (31,5%) e Melipona scutellaris (3,7%). Outros insetos como dípteros (11,1%) também foram observados nas flores. As abelhas Augochloropsis sp., da família Halictidae, aumentaram sua frequência até 11h, diminuindo após esse horário. As abelhas B. atratus visitaram as flores da jurubeba durante todo o dia, com pico de frequência entre 6h e 7h. As abelhas M. scutellaris visitaram as flores da jurubeba apenas entre 7h e 8h. Os dípteros foram observados apenas entre 9h e 12h. Concluiu-se que a jurubeba é uma planta que fornece pólen para diversas espécies de abelhas, sendo importante para a manutenção da biodiversidade dos polinizadores.

    Importância do Trapiá (Crataeva tapia) como fonte de alimento para abelhas africanizadas e nativas
    (2019-01-22) Sousa, Lucas Delano Nascimento de; Souza, Darclet Teresinha Malerbo de; http://lattes.cnpq.br/3266223126925865; http://lattes.cnpq.br/2653613823408122
    The knowledge of the plants of a certain region, its flowering season and the characteristics of the pollen, help in the survey of the availability of food for the bees. Crataeva tapia is a plant of the family Capparidaceae, known as trapiá, that occurs from Pernambuco to São Paulo and Minas Gerais, in the rainforest Atlantic and in the Mato Grosso Pantanal. This study aimed to clarify the importance of trapiá pollinators and their advantages for the mapping of nectar and pollen sources available to Africanized honeybees and native bees. The study was carried out in the Meliponicultura Sector, in the Department of Animal Science, at the Federal Rural University of Pernambuco with a duration of three days of observation, in October and November of 2018. Floral visitors were evaluated, beginning at 6:00 a.m. during 10 minutes and 1 hour intervals until 5:00 p.m., evaluating the habit of collecting each species of insect. The data were statistically analyzed using the Bioestat program and the statistical design used was the Fully-randomized (DIC). Tukey's test was used for the comparison of averages at a 5% probability level. Several species of insects were observed preferably bees. The insects observed were stingless bees Partamona helleri (36.43%) and Plebeia sp. (26.35%), vespids (14.35%), Africanized honeybees Apis mellifera (12.0%), stingless bees Melipona scutellaris (8.13%), carpenter bees Xylocopa frontalis (1.94%) and X. griscenses (0.80%). These bees preferred to collect pollen compared to nectar and only the Africanized honeybees visited these flowers for the collection of nectar and pollen. It was concluded that this plant species can be planted close to apiary and meliponariy being an important source of food for Africanized honeybees and native bees

    “Visitantes florais no margaridão (tithonia diversifolia) com ênfase em abelhas africanizadas e nativas”
    (2019-01-22) Gabriel, Rafaella Ingrid Omena de Abreu; Souza, Darclet Teresinha Malerbo de; http://lattes.cnpq.br/3266223126925865; http://lattes.cnpq.br/1316248218596105
    Bees are undoubtedly the most important pollinators for the reproduction of most angiosperms, either in natural ecosystems or in agricultural plantations. The frequent visit of the bees in the flowers is related to the dependence of the floral resources (nectar and pollen), from the larval phase until the adult phase, being the pollen the source protein and the nectar the energetic source. The objective of this experiment will be to identify floral visitors in daisy (Tithonia Dversifolia), with an emphasis on Africanized and native bees. This experiment will be conducted at the Center for the Conservation of Native Bees, Department of Animal Science, Federal Rural University of Pernambuco, Recife, PE, from August to September 2018. After the start of flowering, the frequency and type of collection (nectar and / or pollen) of the flower visitors, during the day, by counting in the first 10 min of each time, between 6.00 and 17.00, with four replications (four different days). A randomized experimental design with four replications will be used and the Tukey test at the 5% level and polynomial regression in time, using the Bioestat program, will be used. Africanized bees Apis mellifera and native bees were observed in daisy flowers, collecting nectar and pollen. The native bees observed were Melipona scutellaris, Magachile rotundata and Trigona spinipes. Different species of lepidoptera (butterflies) and dipterans (flies) also used daisy flowers as food resources. It was observed that the predominance of the Africanized bees in the flowers compared to the native ones. This species should be planted close to the meliponarios and apiaries, being an important source of food resources for the bees, in Recife, PE, especially after the rainy winter.

    O que faz a polinização ser “o menor dos mundos”? Uma análise a partir de estudos de caso
    (2018) Araújo, Karoline Couto; Bezerra, Elisangela Lucia de Santana; http://lattes.cnpq.br/4360870964749577; http://lattes.cnpq.br/7885361436753765
    Plant-pollinator interaction networks express a typical structure, marked by strong connectivity, degree of dependence and its size. Modularity may also be characterized in this system, especially when it comes to specialized syndromes, involving partners with certain more specific specificities and abilities. Particularly noteworthy are poricidal flowers and vibrating bees, oil flowers and bees collecting floral oils, resin flowers and Euglossini, tubular flowers and their related pollinators, ranging from long-tailed bees or specific hummingbirds to bats and sphingids.In this way, we aim to present a brief analysis to try to portray the biological system that involves the pollinator network in a fragmented Atlantic Forest scenario. Data collection was done through a bibliographic survey based on case studies developed in the PEDI. The works were collected in the database Pergamum and Google Scholar, using theses, dissertations and scientific articles. The keywords used in the search were pollination, reproductive biology and floral biology (pollination, reproductive biology and floral biology).The following information was extracted from the works for the construction of the network: I – name of plant species, II- name of the pollinators identified in the interactions. Then, the binary matrix was applied to Program R for the creation of the network of interaction in graph form. The size of the net found in the PEDI was equal to 60 (49 species of pollinators, being bees, flies and hummingbird and 11 species of plants). The bipartite graph presented heterogeneous connectivity, most interactions were simple, where many species interacted with few partners. From the perspective of pollinators, only Phaethornis ruber made generalist interactions (4). Among the plants, the Byrsonima sericea species presented the most connections (17). The present work concluded that the interaction network presented characteristics that confirm the expected patterns for pollination networks, especially for specialized syndromes.
