Technological advances for screening for and determining the mechanisms and biochemical basis of resistance in maize to the corn earworm Heliothis zea (Boddie), are discussed. Detailed descriptions and illustrations of field infestation techniques, damage rating procedures, and laboratory bioassays are presented for determining nonpreference and antibiosis of resistant maize germplasm to corn earworm.
