The objective of this work was to evaluate the lethal and sublethal toxicity of hexane and methanolic extracts from the leaves of Annona vepretorum (Annonaceae) on Tetranychus urticae (Acari: Tetranychidae). The methanolic extract toxicity was evaluated by Potter tower application (topical + residual effect) and by immersion of Canavalia ensiformis leaf disks in the extract solution (residual contact effect). The hexane extract toxicity was evaluated exclusively through residual contact effect. Sublethal effects of the methanolic extract were evaluated through LC50 on the females. Mite preference for feeding and oviposition was evaluated by multiple choice tests, between the control and the extract concentrations, using the hexane and methanolic extracts. Estimated LC50 for the methanolic extract was 10.96 mg mL-1 for the topic + residual effect and 22.07 mg mL-1 for the residual effect. Estimated LC50 for the h exane extract was 50.61 mg mL-1. The methanolic extract at the previously estimated CL50 interfered in the fecundity and longevity of females, differing significantly from the control treatment. In the multiple choice tests, for both extracts, mites showed a significant preference for the control, both for feeding and oviposition. Annona vepretorum has acaricide effect and constitutes a botanical source with great potential for controlling T. urticae. |

Some regions of the Cerrado Biome present edaphoclimatic conditions restrictive to the maximum productive potential of agriculture and livestock. In these regions, experiments with crop-livestock system (CLS) show that this strategy allows the intensification of agricultural production in a sustainable manner. Rotation, intercropping and succession of crops producing grains or silage with forage species, and conservationist soil management such as no-till and correction of the soil profile favorable to root growth, allow the exploitation of the agricultural area, especially when there is a water deficit. In fifteen years of conducting the CLS, the production of agricultural crops met the demand for food and, also, provided grain yields above regional averages, and even national averages. In addition to the lower risk, the strategy adopted met internal demand and generated surplus grain and silage for commercialization, increasing income. In the temporal analysis of the CLS, the adoption of sustainable soil and crop management practices has, over time, overcome the region's edaphoclimatic limitations, in an economically viable way, based on adequate land use planning, and by the choice of appropriate combination of crops, properly aligned with the livestock activity of interest. |
