In order to know the harmful species (insects and weeds) and beneficial species (arthropods), and their populations, it is that this study was considered important. The results obtained in terms of diversity, population levels of arthropods and weed cover, according to the techniques recommended for each sample, provide insight for this center area of the province of San Luis, species that may act as potential pests and bilógicos controllers.
