| This study aimed to evaluate the influence of the distance from the edge of native forests on the abundance of aphidophagous hoverflies in wheat fields. The study was conducted in four commercial fields in the North of Paraná State, Brazil, during the wheat crop season of 2009. Two transects were surveyed parallel to the edge of the forest at two distances: 25 (“near”) and 525 meters (“far”) from the edge. The abundance of hoverflies was compared using a χ2 test (p ≤ 0.05). In total, 1,845 hoverflies adults were collected, which represented 15 species and three genera. The most abundant species was Allograpta exotica (60.43%), followed by Toxomerus dispar (17.78%) and Toxomerus watsoni (7.26%) (Diptera: Syrphidae). An important inference was that all... |

| In recent years, the Brazilian production of beans (Phaseolus vulgaris L.) has stood out due to the increase in productivity and Paraná has great representativeness in the national context of the product, making relevant the analysis of the economic aspects associated with its production. Thus, this article aimed to present studies associated with the economics of bean production in Paraná, which are the characterization of operating costs and revenues for beans in the black and color group, produced in 1ª and 2ª crops in the period from 2014 to 2018, in 49 production units in the state of Paraná, as well as operating revenues and analysis of grain commercialization margins. The results point to differences between 1ª and 2ª crops in the bean culture in... |
