Resistance in plants to insects is usually associated with the relative amount of damage to plants by pests compared with damage on more susceptible crops. Plant resistance mechanisms are nonpreference, antibiosis, and tolerance. Discussions are presented to illustrate the value of plant resistance in an integrated pest management system with nonpreference, antibiosis, or tolerance as the basis of the resistance. Plant resistance is also shown as the primary insect control agent or in an integrated pest management system with insecticides, biocontrol agents, inherited sterility, or cultural control. Regardless of the situation, a resistant cultivar is more desirable than a susceptible cultivar. The use of the resistant cultivar is biologically, ecologically, economically, and socially feasible.
