ABSTRACT: Proper management of natural areas requires phisical (soil, climate and topography) and biological (fauna, flora and microorganisms) characterization. Such information is extremaly useful for management plans of conservation unit such as National Parks, Extractive Reserves of Natural Resources Reserve (RPPN). This study aimed characterize floristic and phytosociological aspects of the microregion of the Trijuncao Farms. The main phytophysiognomies were evaluated in order to select species with economical potential. The phytofionomics of Mata de Galeria Inundavel (swamped gallery forest), Cerradão, Cerrado, Vereda, Campo Sujo and Campo Limpo, and also Carrasco, a typical vegetation of the transition between Cerrado and Caatinga biome were identified. In the studied are it 478 plant especies were found. This figure represents almost 38% of the flora of the region and at least 7% of the flora of all the Cerrado biome. The most representative botanical family was leguminosae with 53 species. Also, the area presented 125 species with some kind economic potential . A list with each one of these species is presented with vernacular name and possible uses. Althrough preliminary, these are important and show the intense diversity of the Cerrado flora and the significance of its utilization in sustainable manner. |

The persistence and high dispersal of weeds during the off-season can favor the survival of pests and diseases that threaten cultivated crops in Brazil. The fall armyworm, Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae), is one of the principal polyphagous pests that takes advantage of the no-tillage system. Despite its pest status, little is known about S. frugiperda survival and development in alternative hosts, including those resistant to glyphosate. The purpose of this study was to investigate, in laboratory and greenhouse conditions, the adaptive capacity of S. frugiperda in volunteer maize and 6 weeds commonly found in Brazilian agroecosystems, including species with biotypes known for glyphosate resistance, such as fleabane, sourgrass, and goosegrass. We found that S. frugiperda survival and biomass were significantly higher in goosegrass, maize, and johnsongrass in both laboratory and greenhouse conditions. In contrast, fleabane, benghal dayflower, sourgrass, and smooth pigweed caused a decrease in S. frugiperda fitness. Along with S. frugiperda adaptive capacity, our results suggest that its persistence in the field can be directly related to weed control inefficiency during the off-season, increasing the demand for integrated pest and weed management. |
