The Rhipicephalus microplus tick causes enormous economic losses in livestock farming around the world. Despite several promising studies carried out with plant extracts such as Achyrocline satureioides against this ectoparasite, a major obstacle is related to pharmaceutical presentation forms. There is no study showing xantan gum-based hydrogel and polycaprolactone nanoparticles containing A. satureioides extract against R. microplus larvae. The objective of this study was to incorporate A. satureioides extract to develop a nanoformulation (AScn) and a hydrogel (ASlh) and evaluate them against R. microplus larvae with the purpose of increasing the contact time of the extract with the larvae and improve the effectiveness. The ethanolic extracts were incorporated in polycaprolactone nanoparticles and characterized via analysis of the mean hydrodinamic diameter and polidispersity index. The xanthan gum-based hydrogel formulation was prepared with crude extract of A. satureioides 40 mg/mL, 0.25% xanthan gum, and 8% poloxamer, to determine the bioadhesiveness of the formulation in bovine leather and the flow rate of the formulation in the animal. The results in larvae demonstrated that when evaluated in the form of a hydrogel (ASlh), mortality was higher, with 91.48% mortality at a concentration of 20 mg/mL presenting itself as an interesting alternative for controlling this ectoparasite. |

The recent increase on oil prices at the international market, associated with the imminent need to reduce the emission of greenhouse gases, has led governments in several countries, and consequently the international scientific community, to search for new energy sources that could increase the options of the global energy matrix. Among the various sources of materials, currently evaluated as alternatives for energy production, the use of biomass is presented as the most viable (HALL;HOUSE, 1997). Biomass can be defined as a product of the process by which plants capture energy from the sun and transform it into chemical energy through the photosynthesis process. This energy can be converted into electricity, fuel or heat. In this sense, tropical forage grasses are considered as important alternatives sources for energy and biomaterials. Factors such as the large amount of biomass produced by some species, wide climatic and soil adaptation, relatively low demand for inputs; perenniality of the crops, and of course the possibility of their use for production of products such as meat and milk, make them assume an important role in this new energy scenario. For this reason tropical grasses can be grown as a multiple-purpose crop, allowing great flexibility to producers, that can use their fields for both livestock and energy, according to the convenience or market value of each product. Compared to others tropical grasses, Panicum maximum can be considered one of the most promising species to be used as an energy crop, primarily due to its high biomass productivity and wide adaptability (JANK, 1995). The objective of this research was to evaluate the biomass productivity of 24 genotypes of P. maximum, at the Cerrados Research Center (Planaltina, DF), using a crop management to allow maximum biomass productivity and dry matter content.
