Resumo: | The increased corn planting grown in the late season crop and the use of a notillage planting system benefits the development of Spodoptera frugiperda, the main pest of corn crop. Thus, this study aimed to select entomopathogenic nematodes based on the mortality of S. frugiperda, and to adjust the nematode concentrations in the laboratory and evaluate the action of these organisms in greenhouse conditions. Seventeen nematode populations were tested at concentrations of 100, 250, and 500 infective juveniles (IJ)/larvae. The obtained data were submitted to the polynomial regression test. In the greenhouse, corn sowing was performed in plastic buckets with soil, corn straw, and water. After 7 days, Steinernema arenarium or Heterorhabditis sp. RSC02, and the larvae were added (40 larvae, one larvae/repetition). The data were submitted to the variance analysis and the Scott-Knott test (P<0.05). In the laboratory, tests with S. arenarium and Heterorhabditis sp. RSC02 caused mortality of 85 and 90%, respectively, being selected for the concentrations test. Concentrations of 150, 200, 250, 300, and 350IJ larvae-1 were tested. At a concentration of 200IJ larvae-1, S. arenarium and Heterorhabditis sp. RSC02 caused 100 and 97.6% mortality in laboratory, respectively, and in the greenhouse caused 77.5 and 87.5% mortality, respectively, when compared to the control (7.5%). |
