Sumario:Ethanol extracts obtained from aerial parts of 64 native plants from Central Argentina were tested for their insect antifeedant activity against Epilachna paenulata (Coleoptera: Coccinellidae) by choice test. Extracts derived from Achyrocline satureioides (Asteraceae), Baccharis coridifolia (Asterac eae), Baccharis flabellata (Asteraceae), Ruprechtia apetala (Polygonaceae) and Vernonanthura nudiflora (Asteraceae), showed more than 97% inhibition of the feeding of E. paenulata at 100  g/cm 2. These active extracts were further evaluated for their effect iveness against Spodoptera frugiperda (Lepidoptera: Noctuidae). All these extracts except for that derived from A. satureioides, negatively influenced the feeding behavior of S. frugiperda at 100  g/cm 2.
