Antigonon leptopus Hook. & Arn. (Polygonaceae), popularly known as amor-agarradinho, is an ornamental plant widely used as a resource for honey bees and stingless bees, however, there is little information on the diversity of bees that use its floral resources, especially in Brazil. The objective of this study was to identify the diversity and behavior of A. leptopus floral visiting bees, as well as to investigate the influence of the microclimate on floral visits, and the efficiency of bees in pollination of the plant. The data collection occurred in the peak of the blooming of the plant, in an area of semi-arid (Petrolina, Pernambuco State, Brazil). Fourteen species of bees were recorded, most collecting nectar and pollinating the flowers from intrafloral behavior. Apis mellifera, Centris trigonoides, and Trigona spinipes were the most frequent species, respectively. The floral visits were concentrated in the morning period, where lower temperature values and higher relative air humidity were recorded. The bees were very efficient in the pollination of flowers (71.08%), compared to spontaneous self-pollination (2.86%). A. leptopus has mellitophilous flowers, attracting a considerable diversity of species, being characterized as a plant with potential for honey bees and stingless bees, and for providing resources for wild bees.

The horizon of this research is to understand the historian's labor of working with digitized historical sources and digital repositories. The investigation is situated at the intersection of the fields of History of Education and Digital History, producing reflections on the main transformations and challenges faced, both in the production of knowledge and in the investigative practice of historical science. The discussion is theoretically and methodologically supported in the literature on digitized historical sources (Chartier, 2002; Brasil & Nascimento, 2020), as well as in authors who deal with the importance of the creation and maintenance of digital repositories (Bica, Rodrigues & Gervasio, 2019; Andrade, 2017). In this sense, we have selected the repository of the magazine Pour l'Ère Nouvelle as an example. We have concluded that the use of these technological tools has been of great relevance for the Humanities area, above all, due to the influence on the historiographical production that, in turn, derives from the different views, perspectives and actions constituted through the virtual access.
