In the greenhouse, a fall armyworm-resistant (intermediate- preference) cultivar ('Gahi') of pearl millet, Pennisetum typhoides (Bunn.) Stapf and C. E. Hubb, was fertilized with a recommended rate of a complete (NPK) fertilizer and all component nutrient combinations. When larvae of Spodoptera frugiperda (J. E. Smith) were fed the respective foliages, the insect's life cycle was affected significantly. Further, the cultivar as fertilized, also varied in growth vigor and expressed extremes of ranges of host plant resistance (for preference, antibiosis, and tolerance) to the insect. Data show that crop fertilizers induce various insect-control effects in pearl millet forage that must be considered in investigations of field-planted host-plant resistance.
