| Diversas espécies vegetais de interesse agrícola são dependentes das abelhas para polinização. Esse é o caso das plantas auto incompatíveis, como a maioria das espécies do gênero Passiflora. Atualmente, toda a produção do maracujá comercial é obtida praticamente por meio da polinização manual, gerando maiores custos para o sistema de produção e maior dependência de mão-de-obra. Visando à proposição de medidas que promovam o aumento da polinização por abelhas, este estudo teve como objetivo conhecer a fauna de abelhas visitantes florais e potenciais polinizadoras das cultivares de maracujá doce BRS Mel do Cerrado (Passiflora alata), maracujás silvestres BRS Sertão Forte (P. cincinnata) e BRS Pérola do Cerrado (P. setacea), na região do Distrito Federal.... |

| Práticas agrícolas, como escolha e manejo adequado do solo, utilização de cultivares adaptadas à região, adoção de espaçamentos corretos, além de calagem e adubação, irrigação, podas, polinizações manuais, controle fitossanitário de pragas, entre outras, podem levar o maracujazeiro a atingir altas produtividades. Desse modo, a Embrapa Acre coloca à disposição dos produtores, professores e extensionistas, de forma objetiva e concisa, uma importante publicação que aborda as práticas inerentes ao cultivo do maracujazeiro de forma sustentável e econômica. |

| Pollination based on insect deception has been debated in the scientific community since it was first reported over two hundred years ago. A vast majority of deceptive syndromes occur within the orchid family. While many cheating flowers have been described and are well known, there are still many curious cases that need further investigation. One prime example of such a case is Cypripedium calceolus, known as European lady’s slipper orchid. While the flower has been of interest to many prominent scientists for over a century, its pollination is still not fully understood. Both visual and olfactory cues seem to play an important role in pollinator attraction. In this study we focussed on the olfactory cues in order to explore their relationship (in future... |

| • Premise of the Study: Although many species in the orchid genus Coelogyne are horticulturally popular, hardly anything is known about their pollination. Pollinators of three species were observed in the fi eld in Nepal. This information is urgently needed because many orchid species in Nepal are endangered. Whether the exudates produced by extrafl oral nectaries played a role in protection against herbivory was also investigated. • Methods: Pollinators of C. fl accida , C. nitida , and Otochilus albus were filmed, captured, and identifi ed. Ant surveys and exclusion experiments were carried out. To investigate whether pollinators are needed for fruit set, plants were wrapped in mesh wire bags. Infl orescence stems were examined with microscopy. Fehling... |

| It is controversial the role played by Meliponina bees in the pollination of mass flowering trees with small generalized flowers (FMPG), very common group of trees in the tropical forest canopy. The species richness and relative abundance of flower visiting insects of the mass flowering tree Stryphnodendron pulcherrimum were measured to test the hypothesis of tight ecological association between these generalist bees and FMPG and to evaluate the effect of this relationship upon the reproductive success variation among tree crowns. The flower visiting insects were sampled on 10 flowering tree crowns at the Atlantic Rainforest in southern Bahia. Altogether, 553 visiting insects were collected during the flowering period of S. pulcherrimum: 293 (52%)... |

| Abstract: The objective of this work was to evaluate the variations in the stored food resources and in the number of immature bees in Apis mellifera hives used for apple (Malus domestica) pollination. The study was conducted in the municipality of Vacaria, in the state of Rio Grande do Sul, Brazil, with 40 hives, over two consecutive harvests. The evaluations were done in the hive brood frames before, during, and 45 days after a pollination period, by interpreting photographic field records. Before being transported to the orchards, the bees foraged primarily in areas with native forest or canola (Brassica napus) crop, in 2014/2015, and with native forest or eucalyptus (Eucalyptus sp.) reforestation, in 2015/2016. In both harvests, the percentage of food... |

| Apple (Malus domestica Borkh.) trees, cultivars Gala and Fuji, were sprayed at full bloom with thidiazuron (TDZ) at doses of 0, 5, 10, or 20 g ha-1 of a.i. in order to evaluate its effects on plant growth and development, return bloom, fruit set, nutrition, and fruit yield. Fruit set increased with TDZ dose in 'Gala' but not in 'Fuji'. TDZ did not affect fruit yield in any cultivar. In 'Gala', the return bloom was reduced in about 50% at TDZ doses of 10 or 20 g ha-1. TDZ increased shoot growth in both cultivars. In leaves, TDZ decreased the concentration of Ca and Mg in 'Gala' and of Mg in 'Fuji', but did not affect the chlorophyll content, leaf area, length, width, and dry mass per cm² regardless of cultivar. In fruits, the effect of TDZ varied according... |
