Natural areas can increase the number of natural enemies (NE) of agricultural pests in cultivation areas. The level of damage (LD) caused by the fall armyworm in a corn crop was studied in Sete Lagoas, MG. We tested whether the LD increases with the distance to the natural area and that the effect of the distance is null on the new damage in the reproductive period of corn. Rated the LD (450 plants, five distances and five moments), we found that the it was lower in plants close to the natural area and that it was homogeneous in the reproductive period. This suggests that the NE are closer to the natural area, with more food resources and that the NE have homogenized distribution due to their attraction to the resources of the reproductive period of plants. It is suggested that landscape conservation may reduce pest damage in cultivation areas.
