Tests were performed to determine the presence of pests in purple corn crops under environmental conditions of the national university of the Agraria La Molina. There were records of populations of Agrotis spp., Cyanopepla alonzo (Butler), Dalbulus maidis (DeLong & Wolcott), Diabrotica viridula (Fabricius), Diatraea saccharalis (Fabricius), Elasmopalpus lignosellus (Zeller), Euxesta spp., Helicoverpa zea (Boddie), Peregrinus maidis (Ashmead), Rhopalosiphum maidis (Fitch), Spodoptera frugiperda (J.E.Smith), Sthenaridea carmelitana (Carvalho), Tallula atramentalis (Lederer) and natural enemies of these pests, since the crop's emergence to maturity. The plot was located in the so-called Free Field I of the UNALM. With an area of 3.114,8 m2 and perimeter of 227,84 m, 100 plants were picked for each test, split in 10 units per groove. The shoots, stems, 4 leafs at max, panicles and 2 corncobs were examined in each plant; and 4 lineal meters per groove. There was a total of 16 tests, divided in 4 temporary stages, in correspondece to the months of August, September, October and November of 2018. Likewise, an aditional evaluation was performed to the corncobs in the crop. In this study, the most representative pests, by their abundance in population were the order of Hermiptera, D. maidis, P. maidis, R. maidis and S. camelitana; and the order of Diptera, Euxesta spp. The preparation consisted in a deep tillage of the field with 2 previous deep waterings, so that remnant populations of Agrotis spp., S. frugiperda, E. lignosellus and H. zea didn't represent a mayor problem for the crop. insecticides that could affect the beneficial fauna were applied. The temporary stage 4 presented in total the largest population of insects, when the crop was in the maturity phase of corncobs, and records of increase temperature. The damage of insects represented the 50% of the total conrcobs evaluated.
