Abstract
Field data from studies in Colombia and Florida [USA] involving the fall armyworm (FAW), S. frugiperda (J. E. Smith), are presented to illustrate the potential of manipulating plant diversity within crop systems to provide additional safeguards against pest insects. Measurements were made on FAW damage, larval parasitism [Meteorus sp.], predator abundance and crop yields in different corn cropping systems. There is a need for research that is designed to establish the complementarity of a range of crop and weed species in regulating FAW populations in different ecological zones.
